Nutrition - Carbohydrates-Insulin
October 28, 2008This post is in reguard to carbs and losing unwanted body fat. Theres so many different ideas when it comes to diet and proper nutrition. I’m gonna layout some backround on why lowering carbohydrates assist in weight reduction.
Carbohydrates should be eaten and not expelled from your daily diet. However, they should be eaten in moderation and from the proper sources. As you know carbohydrates is sugar. When digested it causes the pancreas to secrete insulin. When insulin raises to high it activates the bodies fat production and storage. This process is further more known as lipogenesis.
Raising insulin can be what you want when trying to increase mass. Raising insulin does prevent fat loss but, makes your body anabolic. An example would be the affect it has on testostrone levels. When insulin is low throughout the body glucose is no longer used and the body turns to fat as a source of energy.
Effects of insulin:
Increases DNA replication and protein synthesis, increases glycogen sythesis, Increases fatty acid sythesis ( lack of insulin causes the reverse ), Increased esterfication of fatty acids sythesis ( insulin makes the adipose tissue to make fats. ), and increased pottasium uptake.
The first step in breaking down carbs is know as glycolysis. This makes a single molecule called glucose. Glucose is produced into ATP. ATP is responsible for all muscle movement. During excercise glucose is split into pyruvate and lactic acid. Lactic acid is the result of muscle fatigue. Lactic acid also causes what we like to call, THE PUMP. Which is something everyone loves lol.
Now we can talk about glycogen. The process in which glycogen arrives is called glycogenesis. This is the convertion of glucose to glycogen. This occurs in the liver where some is also stored. Glycogen is also stored throughout the skeletal system. The glycogen stored in our muscles is the first to be used. This is why it is very important to eat high glycemix carbs after workouts. It’s also important to digest carbs in those longer extended workouts.
Stay away from High fructose corn syrup. It’s literally everywhere. It’s a common sweetner that I believe is the reason for our rediculous obiese rate. Fructose reduces the rate of protein synthesis. It’s also proven to transform into fat faster then any other sugar. If your eating something thats processed, theres a good chance it contains fructose.
More to think about. A significant cut back in carbs upsets the bodies chemical balance. It causes fluids to be expelled from the muscles which you may think is fat loss. Also, muscle tissue is broken down. I’ve been at fault for this in preperation for competition.
Suggestions- Lower your carbs but dont delete them. Eat carbs from the right sources such as whole grains, vegetables and fruits. I generally stick with low glycemic carbs during the day except for post workout. I fluctuate carbohydrates based on my daily activity level.
I wish you all the best.
and remember," Nothing tastes as good as looking good."
