Yesterday, we ran a piece on protein. See http://hollywoodhealthletter.com/2013/05/28/eat-protein-for-better-body-firming/ . Today the emphasis is on dieting and protein.
Sometimes dieters may need more protein.
When dieting, your body requires a little additional protein, but not much.* This is due to the stress and strain you’re placing it under. Failure to replenish the loss, however, results in a decrease in muscle tissue. Don’t forget: Muscles are mainly made up of protein. When you limit protein intake, you risk severe tissue breakdown. This process, known as catabolism, is where the actual muscle tissues are broken down to be used as protein.
Remember, muscle tissue increases your metabolic rate. As a rule, muscles don’t require additional protein for energy.
However, a diet too low in protein may cause a deterioration of muscle tissue, dryness and weakness in the hair, wrinkled skin and lack of stamina. When protein intake is reduced beyond about 12 percent of the total calories consumed, the body uses muscle tissue as a source of energy. Wait! It gets worse. Not only will you lose existing muscle mass, but less tissue will be developed as a result of the drastic protein deficit. Why sacrifice all that strenuous exercising only to lose all that hard-earned muscle tissue?
* This is true unless you’re in a severe state of starvation. When all carbohydrate and fat reserves have been depleted, protein is converted into energy. When you rely upon protein for your major energy supply, the body must rid itself of the excess nitrogen (a by-product of digested protein) in the system. Much of the excretion occurs while urinating. It’s important to drink plenty of water at this time in order to keep the system clean.
