The Science Behind Dieting
By Michael Branin
Most people when they look up how to diet you get the basic you need to burn more calories than you take in and they believe that they found the “secret.” Not so fast their is more to it than that.
What they don’t know is once you start restricting calories it affects your metabolism. The first thing your body does when it is in a caloric deficit is decrease energy output and attempt to increase intake thus it’s attempting to reach metabolic homeostasis.
Your fundamental metabolic rate slows down meaning your body burns less calories while resting.
The thermic affect of food (TEF) decreases meaning the amount of energy used to digest foods decreases. Although restricted calories doesn’t directly affect TEF. The reduction in overall food intake naturally decreases TEF.
You burn less calories during spontaneous activity. Spontaneous activity is non organized exercise, like walking around, talking on the phone, or bobbing your legs while you sit.
You burn less energy through exercise. It makes good sense the less you weigh, the less energy it takes to move. Unfortunately science has shown that you burn less calories even with artificial weight, like a weight vest.
Don’t be discouraged though that why maintaining your macros, sticking to your diet, and exercise are very important parts of losing weight. Remember this a marathon, not a sprint.
