"Problems arise in that one has to find a balance between what people need from you and what you need for yourself." ~Jessye Norman~
This is such a great quote to think about. Once again it brings us to our favorite word, BALANCE. It is so important to find that perfect balance of what people need and what you give and also what you need and give to yourself. Sometimes we find ouselves pleasing others and constantly giving to others but don’t that take away from yourself. It is important to always be giving and looking out for others, but don’t let yourself go to the wasteside… Find that balance of giving to others and to yourself.
one for someone, one for you… one for someone, one for you…
Kind of like the daisy, does he love me, does he love me not analogy.
There are so many times you may find yourself giving giving giving, if that is the type of person you are. Then there comes a day where you look back and maybe you haven’t done some of the things you use to do such as your nails, getting to the gym on a regular basis, watching your diet, spending time with friends, going out for a girls or guys night, reading a book, or whatever it may be. Every now and then you have to check yourself and make sure you are still in that balance of giving to yourself, while still giving to others.
Remember you can not give to others if you don’t give to yourself first. You are so much more productive and there is so much more of you to give when you feel great and have put time and energy into yourself. Some people may see this as being selfish to be thinking about themselves and their needs. Don’t see it as being selfish but see it completely different, flip that attitude… if you are not giving to yourself first you become spread too thin by only giving to others… you are then being self-less because you are not doing much for yourself, and it has the greatest potential to hurt only you until you learn to give to yourself fully FIRST!
It is all about that perfect balance. Don’t worry it is something we all are working towards and it does not come easy. It takes practice and first of all acknowledgment.
How can you give your all to others when you haven’t given it to yourself first?
Finding that balance can be tough but it can be done.
Something to think about….

FOOD ON THE GO OPTIONS…
1-Jamba Juice Hot Oatmeal (w/o Brown Sugar Crumble)
PER SERVING (one container with fruit topping ONLY! 240 - 250 calories, 2.5 - 3g fat, 20 - 30mg sodium, 49 - 52g carbs, 5 - 6g fiber, 16 - 18g sugars, 8 - 9g protein
three fruity toppings: Banana, Blueberry & Blackberry and Apple Cinnamon
Keep in mind the oatmeal will NOT taste like yours that you make with water because it is made with creamy soymilk. Don’t be surprised when it is super delicious!
————————
IHOP Spinach, Mushroom & Tomato Omelette (on the IHOP For Me menu)
PER SERVING (1 order): 330 calories, 7g fat, 660mg sodium, 37g carbs, fiber n.a., sugars n.a., 30g protein
Made with fat-free egg substitute (a.k.a. Egg Beaters), it’s stuffed with spinach, mushrooms, onions and Swiss cheese, topped with diced tomatoes, and served with a side of fruit. It even has a small amount of pancake batter in the mix for added fluff factor. One word of advice, though: Be SURE to specify that you want the “IHOP For Me” omelette — the standard Spinach & Mushroom Omelette has 980 - 1,620 calories and 30 - 41g saturated fat (and the total fat is likely WAY higher than that).
I ask to remove the cheese…. Now these dining out for breakfast options are emergencies only! In my book… but it is good to know that they are out there if you are in a rut!
They are not bad options but I would rather have my oats with water and fruit. It tastes just as good but you are by passing the sugar/calories of the soymilk… Or the Ihop omelet, do you really need that batter. Your egg white omelet is probally just as good if not better and does have that added batter for fluff and flavor!
Even though restaurants are now offering cleaner options, I always say you are better off to A) eat at home, B) Bring your own food OR DO NOT ORDER THEIR “MODIFIED” VERSION BUT RATHER MODIFY ONE OF THEIR MENU OPTIONS ON YOUR OWN. FOR EXAMPLE YOU CAN ORDER AN EGG WHITE OR EGG SUBSTITUTE OMELET WITH VEGGIES WITH NO PROBLEM. THERE MAY BE A SMALL ADDED FEE BUT IT IS WORTH IT…

Water Retention and Bloating- Joanne Lee
I hear these type of situations so often….
You have a great couple weeks with your eating and exercise. You’re starting to really see progress i.e. your clothes are fitting looser, your face looks leaner, your stomach’s tightening up, your energy’s increasing… You’re fired up to weigh yourself because you feel like you have dropped a few lbs! You step on the scale and… what the heck… Your weight is actually up…??? You don’t get it! You see it in the mirror and feel great in your clothes but why is the number on th scale up!? You feel discouraged and frustrated. Sometimes that number does mean something… and sometimes it doesn’t.
There are many factors that determine your weight. The biggest one is water retention. Your body’s made up of between 55%-75% of water. This means that your weight will be directly affected by your body’s retention of water. What causes your body to hold water and what causes it to shed water? This will help you with knowing the difference between water and body fat! Hopefully this will help you avoid those little freakouts! Every cell in your body controls its water balance through a sodium/potassium pump. Potassium resides inside the cell and sodium stays outside the cell. Both of these are electrolytes. An equal balance of sodium to potassium must remain in each cell so that proper cell integrity and water/electrolyte balance can be maintained.
As with every other system in the body, the goal is to maintain homeostasis (balance). Water retention is a side effect of the disruption of this balance. Why does the body retain water? Once the balance is lost, the body will need to make an internal adjustment in order to regain cell balance. Many times, the body adjusts by retaining water. The main reason for this is blood flow. Our circulatory system is the method in which our body is supplied with oxygen. Without water, our blood cannot flow. When there’s a cell imbalance with possible dehydration (lack of water), the body triggers the release of hormones to retain and protect its remaining water and ensure the proper hydration of the body’s blood supply.
What causes water retention? This cell imbalance can be affected by many things; the most frequent are: high sodium and/or carbohydrate foods, a lack of water intake, the ingestion of diuretics (substances that force your body to release water), women’s menstrual cycle and stress. Every gram of sodium and carbohydrates attract 3-4 water molecules. This means when you eat too much sodium or carbohydrates, you’ll will force the body to retain excessive water. Many people also think that drinking water causes water retention… Not true.
In fact, the exact opposite is true. Please remember that the body is a "feed as it goes" machine…
If the body is being fed consistently, it will release consistently. This means by drinking more water, your body will release more water and in turn flush out excess sodium. Taking diuretics or “water pills” are also a big cause of water retention. These substances force the body to release its water and directly affects the sodium/potassium pump of each cell. By taking diuretics, your body begins to rely on them, and temporarily loses its ability to self regulate this internal water balance. This means that when the substances aren’t taken, the body doesn’t know how to release water, causing heavy water retention. Diuretics taken for long periods of time can cause permanent damage to the body’s water regulating system as well as the kidneys.
Another cause of water retention is a women’s menstrual cycle. This is caused by the increased levels of hormones present. Typically, a woman on her menstrual cycle can gain 5-6 lbs. The last thing that frequently causes water retention is stress. Stress is defined as the body’s reaction to change, producing a physical, mental, or emotional response. Stress naturally occurs in life, so in moderation it’s a non-factor. When stress levels reach a high point, they cause a hormonal response that triggers the accumulation and retention of water and toxins in the body.
What are the effects of water retention? When the sodium/potassium pump goes out of balance, the main effect of water retention is weight gain. I’ve seen clients gain 10 lbs of water by eating a heavy sodium/carbohydrate meal alongside a stressful few days. That same 10 lbs will then dissappear a couple days later by eating correctly and managing stress. In this circumstance, the increase of weight is just a sign of water retention and nothing else. It is important to understand and accept that there will be times when your body will retain water and get bloated.
The goal is to know how to avoid this and minimize its happenings…
1. Drink Water You should drink at least 64 oz (2 liters) of water per day, and ideally 96-128 oz (3-4 liters) per day. The best way to tell if you’re drinking enough water is by the color of your urine. If it’s clear you are doing well, if it’s yellow, you’re dehydrated and should increase your daily water intake.
2. Exercise on a regular basis! Movement equals optimal circulation. The more efficient you are with your exercise, the better your body can remove excess water.
3. Eat High Quality Foods The ideal sodium/potassium ratio in mg is 1:3. The great news is that if you eat high quality foods, you’ll automatically hit that ratio. If it has 3 or less ingredients, it is of great quality. More ingredients means more processing, and that typically means higher sodium. A good rule is to center your meals on higher quality foods. This will ensure minimal water retention and bloating.
4. Manage Stress Levels Stress causes the over release of the hormone cortisol. Cortisol is a water retaining, fat storing hormone. Managing your stress levels will help reduce water retention and bloating. Remember this the next time you step on the scale. If you know you have been following your program and have done nothing that could have possibly caused weight gain, it is most likely just water!
So the next time you step on that scale, if your socks leave an imprint in your legs (I hate that!), or your face looks fuller than normal, or your rings don’t fit your fingers… I invite you to remember your new found understanding about water retention and bloating. If the cause of those things is an occasional “off plan” meal or a stressful day, it’s just excess water. If you get back on track by implementing these 4 strategies that water retention will be gone in a day or two… there is never a need to panic once you understand the process.

The Cheat Meal
The Cheat Meal… There comes a day in most dieters’ lives when a cheat meal is necessary. And depending on your personality, you either love it or hate it. There are those who look forward to a cheat meal because it gives some psychological relief from the strictness of a stringent diet and gives an energy boost that rejuvenates a heavily trained body! Then there are the dieters who use a cheat meal as a license to overeat. This, by the way, is not a true cheat! It is a binge!
On the other side of the spectrum, we have dieters who dread a cheat meal…athletes who are so locked into "the zone" that they are afraid to eat anything other than what is on their base meal plan. Even though their metabolism may be slowing, they may be losing muscle and they may be suffering from the fatigue a tough diet can induce, they refuse to cheat.
The benefits of cheating, and the importance of cheating when you are told to (and only when you are told to in some cases!)
What is a Cheat Meal?
The definition of a Cheat Meal is a meal that is higher in calories (and potentially higher in carbs or healthy fats) but is still nutritionally dense. In other words, eating foods that your body can put to good use, such as a steak and a potato (or even Chipotle!) and NOT eating empty calories like sweets and highly processed foods.
An important note that many dieters may not be aware of, is that a cheat meal is meant to be consumed within a 20 minute time frame. It is a MEAL not a DAY! The benefits are to be gained from one caloric boost, not a day long binge that, instead of stoking the metabolism, instead overwhelms the body’s systems. Such prolonged overeating stresses your digestive system and leads to unwanted fat storage.
Benefits of Cheating
When you are on a very restrictive diet, as time goes on, the metabolism begins to slow, adapting to the current calorie intake you are taking in. So, for example, if you used to require 1800 calories to maintain your weight, but have been dieting at a level closer to around 1300, you now may only require 1600 calories to just maintain because of the fact the metabolism has slowed. The degree of slow-down that you experience will vary depending on how severe your diet is and how lean you are to start with, but one thing is for certain, long periods of dieting can spell trouble for metabolic rates. When you incorporate in a cheat meal you may trick your metabolism into thinking that it’s okay to speed up once again. Basically, that famine it thought was occurring is not.
Physically, as you diet to break down fat, you also inevitably break down muscle. The less fat you have to lose, the more your body will turn to muscle when it requires a source of energy. By eating a cheat meal, you fill your glycogen stores, offsetting catabolism and maintaining that hard earned muscle. Since muscle tissue burns calories at a higher rate than other body tissues, you are also maintaining a higher metabolic rate based on your body composition!
Cheat meals also offer a great energy boost. When trying to lose body fat, you are not only dieting, but you are training hard as well. A depleted body cannot work as hard and thereby burns fewer calories. A nutritious cheat meal can boost energy levels for days, allowing for increased training intensity and more effective workouts.
In addition to this, cheat meals can also help your psychological mindset, making it that much easier to stick with a diet program. A bit of relief and slight indulgence can satisfy cravings and make the focus and discipline required for intense dieting possible.
To Cheat Or Not To Cheat
Cheat meal frequency and/or size should be minimized when you are carrying high levels of body fat. Basically, the more fat you carry, the more likely that any excess food will be shuttled toward body-fat storage rather than muscle mass, whereas, the leaner you are, the more likely you are to burn those calories or use them for muscle retention.
Here are the physiological benefits of cheating, when it is appropriate:
- Increased release of thyroid hormone (T3 and T4).
- Increased thermic effect of feeding. This is the energy expenditure for metabolizing the food.
- Increased spontaneous activity or NEAT (non-exercise activity thermogenesis). This represents the activities of daily living, changes of posture, and fidgeting.
It’s important to note that individual responses are quite variable. In fact, as you might expect, your genetic make-up and exercise activity have a lot to do with your response. Your degree of leanness is also an important factor. This is where the timing of a cheat in a diet plan is crucial!! Cheat too soon and you undo your hard work and set yourself back days and even weeks in the process!
Physiological responses to cheating based on these variables:
- Lean people have a significant increase in sympathetic autonomic nervous system activity while obese people often have no response.
- Lean and obese people show increases in T3 and T4 release but there’s large variability. This variability may be explained by the fact that the obese may release less thyroid hormone when overfeeding.
- When exercise-trained people overeat, they may store more carbohydrate while burning more fat. Non-exercisers, on the other hand, may store more fat and burn more carbohydrate.
- Weight-gain resistant people tend to experience huge increases in NEAT as a result of cheating (most of the extra calories are burned, not stored), while people who gain weight easily tend to store most of the extra calories as fat. In one overfeeding study, subjects were given 1000 calories above maintenance per day. The weight-gain resistant subjects in this study oxidized 70% of those 1000 calories. Those who gain weight easily actually stored most of those calories as fat. After 8 weeks of this cheating pattern, fat gain varied almost 10-fold among subjects, ranging from a gain of only 0.79 lb to a gain of 9.31 lb!
- In lean people, the normal insulin response to a meal only minimally affects fat mobilization and fat storage. However, in fatter people, the normal insulin response to a meal nearly shuts down fat mobilization and leads to large increases in fat storage.
As you can see, reaping the benefits of a cheat meal depend on a few different factors. The more body fat you carry, the more likely you are to store those “cheat” calories as fat; the leaner you are, the more likely you are to burn those calories. In addition, genetics play a big role. Since some people respond to cheating by boosting their metabolisms dramatically while others respond by storing that energy as fat. You must also define exactly what you’re hoping to accomplish with the cheat. Are you hoping to make the diet psychologically easier? Are you hoping to increase the intensity of your subsequent workouts so that you can burn more calories during and after the workout? All of these factors play a role in determining whether to cheat or not to cheat.
SO, start considering all of these variables when incorporating cheat meals into your nutrition plan. If you do not have them on your plan given bya trainer or nutritionist, do not take or add them! Your body is not ready for it and there will be no benefits, only set backs and the undoing of weeks of focus and hard work. If you are asked to take a cheat meal, enjoy it! Eat something to replenish your body and know that you are refueling your muscles and, if eating responsibly, you are increasing your metabolism!
Remember: “Don’t Cheat Yourself, Treat Yourself”…but only when it’s appropriate!

Found this great article in TIME magazine online…..
As I write this, tomorrow is Tuesday, which is a cardio day. I’ll spend five minutes warming up on the VersaClimber, a towering machine that requires you to move your arms and legs simultaneously. Then I’ll do 30 minutes on a stair mill. On Wednesday a personal trainer will work me like a farm animal for an hour, sometimes to the point that I am dizzy — an abuse for which I pay as much as I spend on groceries in a week. Thursday is "body wedge" class, which involves another exercise contraption, this one a large foam wedge from which I will push myself up in various hateful ways for an hour. Friday will bring a 5.5-mile run, the extra half-mile my grueling expiation of any gastronomical indulgences during the week.
I have exercised like this — obsessively, a bit grimly — for years, but recently I began to wonder: Why am I doing this? Except for a two-year period at the end of an unhappy relationship — a period when I self-medicated with lots of Italian desserts — I have never been overweight. One of the most widely accepted, commonly repeated assumptions in our culture is that if you exercise, you will lose weight. But I exercise all the time, and since I ended that relationship and cut most of those desserts, my weight has returned to the same 163 lb. it has been most of my adult life. I still have gut fat that hangs over my belt when I sit. Why isn’t all the exercise wiping it out? (Read “The Year in Medicine 2008: From A to Z.”)
It’s a question many of us could ask. More than 45 million Americans now belong to a health club, up from 23 million in 1993. We spend some $19 billion a year on gym memberships. Of course, some people join and never go. Still, as one major study — the Minnesota Heart Survey — found, more of us at least say we exercise regularly. The survey ran from 1980, when only 47% of respondents said they engaged in regular exercise, to 2000, when the figure had grown to 57%.
And yet obesity figures have risen dramatically in the same period: a third of Americans are obese, and another third count as overweight by the Federal Government’s definition. Yes, it’s entirely possible that those of us who regularly go to the gym would weigh even more if we exercised less. But like many other people, I get hungry after I exercise, so I often eat more on the days I work out than on the days I don’t. Could exercise actually be keeping me from losing weight?
The conventional wisdom that exercise is essential for shedding pounds is actually fairly new. As recently as the 1960s, doctors routinely advised against rigorous exercise, particularly for older adults who could injure themselves. Today doctors encourage even their oldest patients to exercise, which is sound advice for many reasons: People who regularly exercise are at significantly lower risk for all manner of diseases — those of the heart in particular. They less often develop cancer, diabetes and many other illnesses. But the past few years of obesity research show that the role of exercise in weight loss has been wildly overstated. (Read “Losing Weight: Can Exercise Trump Genes?”)
“In general, for weight loss, exercise is pretty useless,” says Eric Ravussin, chair in diabetes and metabolism at Louisiana State University and a prominent exercise researcher. Many recent studies have found that exercise isn’t as important in helping people lose weight as you hear so regularly in gym advertisements or on shows like The Biggest Loser — or, for that matter, from magazines like this one.
The basic problem is that while it’s true that exercise burns calories and that you must burn calories to lose weight, exercise has another effect: it can stimulate hunger. That causes us to eat more, which in turn can negate the weight-loss benefits we just accrued. Exercise, in other words, isn’t necessarily helping us lose weight. It may even be making it harder.
The Compensation Problem
Earlier this year, the peer-reviewed journal PLoS ONE — PLoS is the nonprofit Public Library of Science — published a remarkable study supervised by a colleague of Ravussin’s, Dr. Timothy Church, who holds the rather grand title of chair in health wisdom at LSU. Church’s team randomly assigned into four groups 464 overweight women who didn’t regularly exercise. Women in three of the groups were asked to work out with a personal trainer for 72 min., 136 min., and 194 min. per week, respectively, for six months. Women in the fourth cluster, the control group, were told to maintain their usual physical-activity routines. All the women were asked not to change their dietary habits and to fill out monthly medical-symptom questionnaires.
The findings were surprising. On average, the women in all the groups, even the control group, lost weight, but the women who exercised — sweating it out with a trainer several days a week for six months — did not lose significantly more weight than the control subjects did. (The control-group women may have lost weight because they were filling out those regular health forms, which may have prompted them to consume fewer doughnuts.) Some of the women in each of the four groups actually gained weight, some more than 10 lb. each.
What’s going on here? Church calls it compensation, but you and I might know it as the lip-licking anticipation of perfectly salted, golden-brown French fries after a hard trip to the gym. Whether because exercise made them hungry or because they wanted to reward themselves (or both), most of the women who exercised ate more than they did before they started the experiment. Or they compensated in another way, by moving around a lot less than usual after they got home.
The findings are important because the government and various medical organizations routinely prescribe more and more exercise for those who want to lose weight. In 2007 the American College of Sports Medicine and the American Heart Association issued new guidelines stating that “to lose weight … 60 to 90 minutes of physical activity may be necessary.” That’s 60 to 90 minutes on most days of the week, a level that not only is unrealistic for those of us trying to keep or find a job but also could easily produce, on the basis of Church’s data, ravenous compensatory eating.
It’s true that after six months of working out, most of the exercisers in Church’s study were able to trim their waistlines slightly — by about an inch. Even so, they lost no more overall body fat than the control group did. Why not?
Church, who is 41 and has lived in Baton Rouge for nearly three years, has a theory. “I see this anecdotally amongst, like, my wife’s friends,” he says. “They’re like, ‘Ah, I’m running an hour a day, and I’m not losing any weight.’” He asks them, “What are you doing after you run?” It turns out one group of friends was stopping at Starbucks for muffins afterward. Says Church: “I don’t think most people would appreciate that, wow, you only burned 200 or 300 calories, which you’re going to neutralize with just half that muffin.”
You might think half a muffin over an entire day wouldn’t matter much, particularly if you exercise regularly. After all, doesn’t exercise turn fat to muscle, and doesn’t muscle process excess calories more efficiently than fat does?
Yes, although the muscle-fat relationship is often misunderstood. According to calculations published in the journal Obesity Research by a Columbia University team in 2001, a pound of muscle burns approximately six calories a day in a resting body, compared with the two calories that a pound of fat burns. Which means that after you work out hard enough to convert, say, 10 lb. of fat to muscle — a major achievement — you would be able to eat only an extra 40 calories per day, about the amount in a teaspoon of butter, before beginning to gain weight. Good luck with that.
Fundamentally, humans are not a species that evolved to dispose of many extra calories beyond what we need to live. Rats, among other species, have a far greater capacity to cope with excess calories than we do because they have more of a dark-colored tissue called brown fat. Brown fat helps produce a protein that switches off little cellular units called mitochondria, which are the cells’ power plants: they help turn nutrients into energy. When they’re switched off, animals don’t get an energy boost. Instead, the animals literally get warmer. And as their temperature rises, calories burn effortlessly.
Because rodents have a lot of brown fat, it’s very difficult to make them obese, even when you force-feed them in labs. But humans — we’re pathetic. We have so little brown fat that researchers didn’t even report its existence in adults until earlier this year. That’s one reason humans can gain weight with just an extra half-muffin a day: we almost instantly store most of the calories we don’t need in our regular (”white”) fat cells.
All this helps explain why our herculean exercise over the past 30 years — all the personal trainers, StairMasters and VersaClimbers; all the Pilates classes and yoga retreats and fat camps — hasn’t made us thinner. After we exercise, we often crave sugary calories like those in muffins or in “sports” drinks like Gatorade. A standard 20-oz. bottle of Gatorade contains 130 calories. If you’re hot and thirsty after a 20-minute run in summer heat, it’s easy to guzzle that bottle in 20 seconds, in which case the caloric expenditure and the caloric intake are probably a wash. From a weight-loss perspective, you would have been better off sitting on the sofa knitting.
Self-Control Is like a Muscle
Many people assume that weight is mostly a matter of willpower — that we can learn both to exercise and to avoid muffins and Gatorade. A few of us can, but evolution did not build us to do this for very long. In 2000 the journal Psychological Bulletin published a paper by psychologists Mark Muraven and Roy Baumeister in which they observed that self-control is like a muscle: it weakens each day after you use it. If you force yourself to jog for an hour, your self-regulatory capacity is proportionately enfeebled. Rather than lunching on a salad, you’ll be more likely to opt for pizza.
If evolution didn’t program us to lose weight through exercise, what did it program us to do? Doesn’t exercise do anything?
Sure. It does plenty. In addition to enhancing heart health and helping prevent disease, exercise improves your mental health and cognitive ability. A study published in June in the journal Neurology found that older people who exercise at least once a week are 30% more likely to maintain cognitive function than those who exercise less. Another study, released by the University of Alberta a few weeks ago, found that people with chronic back pain who exercise four days a week have 36% less disability than those who exercise only two or three days a week.
But there’s some confusion about whether it is exercise — sweaty, exhausting, hunger-producing bursts of activity done exclusively to benefit our health — that leads to all these benefits or something far simpler: regularly moving during our waking hours. We all need to move more — the Centers for Disease Control and Prevention says our leisure-time physical activity (including things like golfing, gardening and walking) has decreased since the late 1980s, right around the time the gym boom really exploded. But do we need to stress our bodies at the gym?
Look at kids. In May a team of researchers at Peninsula Medical School in the U.K. traveled to Amsterdam to present some surprising findings to the European Congress on Obesity. The Peninsula scientists had studied 206 kids, ages 7 to 11, at three schools in and around Plymouth, a city of 250,000 on the southern coast of England. Kids at the first school, an expensive private academy, got an average of 9.2 hours per week of scheduled, usually rigorous physical education. Kids at the two other schools — one in a village near Plymouth and the other an urban school — got just 2.4 hours and 1.7 hours of PE per week, respectively.
To understand just how much physical activity the kids were getting, the Peninsula team had them wear ActiGraphs, light but sophisticated devices that measure not only the amount of physical movement the body engages in but also its intensity. During four one-week periods over consecutive school terms, the kids wore the ActiGraphs nearly every waking moment.
And no matter how much PE they got during school hours, when you look at the whole day, the kids from the three schools moved the same amount, at about the same intensity. The kids at the fancy private school underwent significantly more physical activity before 3 p.m., but overall they didn’t move more. “Once they get home, if they are very active in school, they are probably staying still a bit more because they’ve already expended so much energy,” says Alissa Frémeaux, a biostatistician who helped conduct the study. “The others are more likely to grab a bike and run around after school.”
Another British study, this one from the University of Exeter, found that kids who regularly move in short bursts — running to catch a ball, racing up and down stairs to collect toys — are just as healthy as kids who participate in sports that require vigorous, sustained exercise.
Could pushing people to exercise more actually be contributing to our obesity problem? In some respects, yes. Because exercise depletes not just the body’s muscles but the brain’s self-control “muscle” as well, many of us will feel greater entitlement to eat a bag of chips during that lazy time after we get back from the gym. This explains why exercise could make you heavier — or at least why even my wretched four hours of exercise a week aren’t eliminating all my fat. It’s likely that I am more sedentary during my nonexercise hours than I would be if I didn’t exercise with such Puritan fury. If I exercised less, I might feel like walking more instead of hopping into a cab; I might have enough energy to shop for food, cook and then clean instead of ordering a satisfyingly greasy burrito.
The problem ultimately is about not exercise itself but the way we’ve come to define it. Many obesity researchers now believe that very frequent, low-level physical activity — the kind humans did for tens of thousands of years before the leaf blower was invented — may actually work better for us than the occasional bouts of exercise you get as a gym rat. “You cannot sit still all day long and then have 30 minutes of exercise without producing stress on the muscles,” says Hans-Rudolf Berthoud, a neurobiologist at LSU’s Pennington Biomedical Research Center who has studied nutrition for 20 years. “The muscles will ache, and you may not want to move after. But to burn calories, the muscle movements don’t have to be extreme. It would be better to distribute the movements throughout the day.”
For his part, Berthoud rises at 5 a.m. to walk around his neighborhood several times. He also takes the stairs when possible. “Even if people can get out of their offices, out from in front of their computers, they go someplace like the mall and then take the elevator,” he says. “This is the real problem, not that we don’t go to the gym enough.
I was skeptical when Berthoud said this. Don’t you need to raise your heart rate and sweat in order to strengthen your cardiovascular system? Don’t you need to push your muscles to the max in order to build them?
Actually, it’s not clear that vigorous exercise like running carries more benefits than a moderately strenuous activity like walking while carrying groceries. You regularly hear about the benefits of exercise in news stories, but if you read the academic papers on which these stories are based, you frequently see that the research subjects who were studied didn’t clobber themselves on the elliptical machine. A routine example: in June the Association for Psychological Science issued a news release saying that “physical exercise … may indeed preserve or enhance various aspects of cognitive functioning.” But in fact, those who had better cognitive function merely walked more and climbed more stairs. They didn’t even walk faster; walking speed wasn’t correlated with cognitive ability.
There’s also growing evidence that when it comes to preventing certain diseases, losing weight may be more important than improving cardiovascular health. In June, Northwestern University researchers released the results of the longest observational study ever to investigate the relationship between aerobic fitness and the development of diabetes. The results? Being aerobically fit was far less important than having a normal body mass index in preventing the disease. And as we have seen, exercise often does little to help heavy people reach a normal weight. (Read “Physical Fitness — How Not to Get Sick.”)
So why does the belief persist that exercise leads to weight loss, given all the scientific evidence to the contrary? Interestingly, until the 1970s, few obesity researchers promoted exercise as critical for weight reduction. As recently as 1992, when a stout Bill Clinton became famous for his jogging and McDonald’s habits, the American Journal of Clinical Nutrition published an article that began, “Recently, the interest in the potential of adding exercise to the treatment of obesity has increased.” The article went on to note that incorporating exercise training into obesity treatment had led to “inconsistent” results. “The increased energy expenditure obtained by training may be compensated by a decrease in non-training physical activities,” the authors wrote.
Then how did the exercise-to-lose-weight mantra become so ingrained? Public-health officials have been reluctant to downplay exercise because those who are more physically active are, overall, healthier. Plus, it’s hard even for experts to renounce the notion that exercise is essential for weight loss. For years, psychologist Kelly Brownell ran a lab at Yale that treated obese patients with the standard, drilled-into-your-head combination of more exercise and less food. “What we found was that the treatment of obesity was very frustrating,” he says. Only about 5% of participants could keep the weight off, and although those 5% were more likely to exercise than those who got fat again, Brownell says if he were running the program today, “I would probably reorient toward food and away from exercise.” In 2005, Brownell co-founded Yale’s Rudd Center for Food Policy and Obesity, which focuses on food marketing and public policy — not on encouraging more exercise.
Some research has found that the obese already “exercise” more than most of the rest of us. In May, Dr. Arn Eliasson of the Walter Reed Army Medical Center reported the results of a small study that found that overweight people actually expend significantly more calories every day than people of normal weight — 3,064 vs. 2,080. He isn’t the first researcher to reach this conclusion. As science writer Gary Taubes noted in his 2007 book Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health, "The obese tend to expend more energy than lean people of comparable height, sex, and bone structure, which means their metabolism is typically burning off more calories rather than less."
In short, it’s what you eat, not how hard you try to work it off, that matters more in losing weight. You should exercise to improve your health, but be warned: fiery spurts of vigorous exercise could lead to weight gain. I love how exercise makes me feel, but tomorrow I might skip the VersaClimber — and skip the blueberry bar that is my usual postexercise reward.
