Article # 533. Benefits of High Protein Diet Foods in Weight Loss

Scientists now believe they know why protein rich diets, such as the Atkins diet, curb hunger pangs. High protein diet foods spark glucose production in the small intestine, which satiates hunger and makes you feel full. (satiety) Researchers concluded that the findings may help development of new treatments for eating disorders, such as bulimia and anorexia.

Researchers found that feeding rats high protein diet foods significantly increased the activity of genes involved in glucose production in the rat's small intestine. This action, led to increased glucose production, (recognized by the liver then relayed to the brain), which caused the animals to cut down their food consumption.

In simple terms, eating high protein diet foods suppresses your appetite, which helps you eat less food. Some evidence also suggest that diets higher in protein increase fat loss as compared to diets lower in protein.

High protein diet foods improve body composition, enhance weight loss, and improve glucose and insulin homeostasis. (balance) Proteins should be selected carefully however, as many high-protein foods are also high in fat. (Steak, bacon, sausage.) If you modify your diet to include more high protein diet foods, you should also include some plant protein food sources, such as soy, beans, and pulses, which they are naturally low in fat. Good sources of animal proteins are baked or broiled fish and chicken. They are low in saturated fat and high in unsaturated fats, such as omega-3 fatty acids. Fried chicken and fish are awfully good to eat, but are high in saturated fat and are not considered good sources of high protein diet foods.

A good protein rich diet is required for optimum health as your muscles, (which constitute about 40-50% of the body mass), are mostly composed of it.
Amino acids supplied from dietary protein are needed for synthesis of body proteins in muscle, organs, bone and skin, and for synthesis of enzymes, certain hormones, antibodies and a host of specialized products. Certain amino acids are essential for proper functioning of the body and the brain, such as 
Tryptophan found in corn and turkey.

Various specific proteins, (produced as a result of gene expression), carry out all general functioning of the body. That is, the genetic pool of the human body that is composed of DNA and its associated genes give rise to specific proteins that carry out very specific functions. Deficiencies in protein of one or more of the essential amino acids can lead to reduced growth in children or loss of muscle mass in adults.

In summary:

• Higher protein diets have been associated with lower blood pressure and reduced risk of coronary heart disease.

• The exchange of protein for carbohydrates has been shown to improve blood lipids.

• Higher protein diets facilitate significant weight loss when compared to a lower protein diet.

• Evidence suggests that protein exerts an increased thermic effect when compared to fats and carbohydrates.

• High protein diet foods increase satiety when compared to lower protein diet foods.
