Keep your Carbohydrates Tank on Full
When you eat a meal, some of the carbohydrate you consume tops up the glycogen stores. If you skimp on carbohydrates because you are following a low-calorie, low-carbohydrate, and/or high-protein diet, your glycogen stores will be inadequate and you will feel it. You will have diminished energy, stamina, and endurance.

Excess Carbohydrate Calories Don’t Turn to Fat
Although scientific research has proven over and over that excess carbohydrates are burned and released as heat, people still believe that carbohydrates turn to fat. Scientific experiments have shown that only if you were to eat more than 2200 calories of pure carbohydrate in addition to your normal daily total calorie intake for 5 to 6 days in a row might the excess carbohydrates possibly turn to fat. This is called glycogen loading and is not so easy to do.

Protein: Overrated
The role of protein in our diets is greatly misunderstood. Although many people associate rippling muscles with a diet of steaks and chops, the protein you eat doesn’t build bulging biceps and triceps. It is used to rebuild muscle.

We tend to think of muscle as a permanent structure, but it is constantly being broken down and rebuilt (in response to use). When muscle is broken down, protein is released and burned. Since only small amounts of muscle are broken down and rebuilt each day, you don’t need much protein in your diet. Scientific research has shown that adults need only about 12-15% of their calories from protein. And no matter what we eat, we generally get that amount.

Most Americans eat more than enough protein for good health. Consuming too much protein can put stress on the kidneys. In addition, since many people equate high-quality protein with red meat, and since red meat is filled with saturated fat, by eating lots of red meat you may be raising your cholestrol level and putting your heart at risk.
