Metabolism Part 2 - Understanding Your Metabolism - Part 1!

This is the second part of metabolism series on healthpub.co.cc, this is for you to really understand how your metabolism works and what can be changed, here are the first three of six important facts you must remember:

1. Fat sorage is a Survival Mechanism
Early humans needed some kind of physical means to store energy so that they could do the wearing work of hunting down large animals, sometimes over great distances, and running down smaller swift animals. This energy took the form of extra body fat.
While each person has a different ideal percentage of body fat depending on gender and frame size, generally an average healthy body fat is 18–22 percent for women and 15–17 percent for men.

2. Eat more
Eating too few calories for the efficient functioning of your metabolism ultimately results in more stored fat. This might sound like a contradiction, but eating a low-calorie diet over a long period of time actually causes the body to begin to hang on to the fat supplies it has and even add to them. Almost everyone who has ever been on a low-calorie deprived diet knows that at first the pounds just melt off. But eventually you reach a plateau where you stop losing weight, no matter how hard you try. That is your body’s natural fat-storing survival mechanism kicking in.

3. Do not fear carbohydrates
People avoid carbohydrates because they think they are fattening. But you should not do that, because you need a basic amount of carbohydrates just to keep brain function and other metabolic processes efficient. That is because a low-carbohydrate diet can make you feel exhausted and irritable. If you do not eat carbohydrates at all (fasting) you can induce ketosis. This condition occurs when the body is unable to completely burn fat for energy. You should at least consume 50 grams of carbohydrates daily to avoid ketosis.

Simple carbohydrates
These are those that have been processed and broken down before being put back together again in an unnatural way such as to produce a sweet product. Sugary and over-processed foods such as candy, cake, and soft drinks are simple carbohydrates.

Complex carbohydrates
Bran muffins, brown rice, and whole-grain breads are complex carbohydrates. Also, each fruit, vegetable, and grain has a different rate of digestion based on the glycemic index. Carbohydrates that digest slowly and release their energy into the bloodstream gradually result in less stored fat than those that digest quickly, releasing their energy in amounts greater than the body can use.
