A new study funded by the National Institutes of Health published in
the Journal of the American Medical Association this week shows that
dieters who were trying to maintain their weight loss burned
significantly more calories eating a low-carb diet than they did eating a
From USA today:
"scientists had 21 obese participants, ages 18 to 40, lose 10% to 15% of their initial body weight (about 30 pounds). After their weight had stabilized, each
participant followed one of three different diets for four weeks.
Participants were fed food that was prepared for them by diet experts.
The dieters were admitted to the hospital four times for medical and
The diets had the same number of calories, but the fat, protein and carbohydrate content varied. Those diets:
- A low-fat diet which was about 20% of calories from fat and emphasized whole-grain products and fruits and vegetables.
- A low-carb diet, similar to the Atkins diet, with only 10% of calories
from carbohydrates. It emphasized fish, chicken, beef, eggs, cheese,
some vegetables and fruits while eliminating foods such as breads,
pasta, potatoes and starchy vegetables.
- A low-glycemic index diet, similar to a Mediterranean diet, made up of vegetables, fruit, beans, healthy fats (olive oil, nuts) and mostly healthy grains
(old-fashioned oats, brown rice). These foods digest more slowly,
helping to keep blood sugar and hormones stable after the meal.
Findings, published in this week's Journal of the American Medical Association:
Participants burned about 300 calories more a day on a low-carb diet
than they did on a low-fat diet. "That's the amount you'd burn off in an
hour of moderate intensity physical activity without lifting a finger,"
says senior author David Ludwig, director of the New Balance Foundation
Obesity Prevention Center at Boston Children's Hospital.
"Participants burned 150 calories more on the low-glycemic index diet than the
low-fat diet. That's about an hour of light physical activity," he says.
The reason for the low-carb advantage is unclear, he says.
"We think the low-carb and low-glycemic index diets, by not causing the
surge and crash in blood sugar, don't trigger the starvation response.
When the body thinks it's starving, it turns down metabolism to conserve
energy," he says."

Muscle time under tension during resistance exercise stimulates differential muscle protein sub-fractional synthetic responses in men.
"...greater muscle time under tension increased the acute amplitude of
mitochondrial and sarcoplasmic protein synthesis and also resulted in a
robust, but delayed stimulation of myofibrillar protein synthesis 24-30 h
after resistance exercise."
i just wanted you to know that i had an awesome day today.
& i hope that you did, too.

ok, so you may or may not know that storing food and heating up food in plastics can be hazardous to your health. do you know what those little recycling codes on your plastic containers mean? you know, the little symbol that looks like this:
each symbol has a different number inside of it representing the type of polymer that makes up the plastic. here's a handy little guide showing the symbol, the polymer name, and it's abbreviation. it also has a little blurb with some interesting info about each polymer.
