High protein diets for weight lossA high protein diet can aid weight loss although for reasons not previously foreseen by many dieters. It is believed that a high protein diet, low in carbohydrates helps burn more calories when the body converted protein to glucose, a process known as gluconeogenesis. In fact evidence suggests that the amount of extra energy used for this process is insignificant.
Many Atkins diet devotees were also lead to believe that additional energy is lost in the urine when in ketosis, a metabolic condition often experienced on high protein diets. A recent study proved there is no real difference in energy losses in urine between low fat dieters and high protein diet followers. So how do high protein diets aid weight loss? Atkins dieters believed they had the best of both worlds, the ability to eat high protein, high fat foods and as much as desired while still losing weight quicker than on conventional low fat diets. The weight loss is fast and mainly during the initial stages on a high protein diet, however the loss is caused by a net loss of body fluids. Protein and carbohydrates both help hold water in cells, during the high protein diet there is a net loss of protein and carbohydrate stores are virtually emptied. When lost from the body these nutrients draw water and thus extra weight from the body but fat stores are hardly changed. Despite the loss in body fluids a high protein diet continues to produce weight loss after this initial period. A study has revealed people on high protein diets actually ended up consuming less calories even though Atkins high protein regime suggests they eat all they want. Protein seems to act like an appetite suppressant thus hunger pangs are easily controlled. High protein dieters no longer seem to binge between meals. Eating only high protein foods also restricts food choices, there is less variety of foods. Studies have shown eating the same or similar foods at each meal dulls the palate and encourages people to eat less. People will consume more when a meal or diet contains a greater variety of food. They believe this may be linked to primitive times, its possible our ancestors were born with a physiologically active appetite that craved a variety of foods in order to obtain all nutrients, this would help decrease any chances of nutritional deficiencies. This new research suggests it is not the type of diet that is the key to weight loss but rather what many scientists have always believed, the need to control energy intake. The first law of thermodynamics still holds true, "energy cannot be created or destroyed it is merely transferred from one form into another". Is a high protein diet with all the negative characteristics and potential health problems really worth the hassle just to form an appetite suppressant?
