Because protein does not appear to be the sole type of food mankind is designed to consume, it is recommended that you talk to your physician before undertaking such a diet. Whatever opinions are expressed in this article, they are just opinions based on small observations that may only apply to individuals other than you. Consult your doctor about anything you read here before making any major changes in how you eat.
What we don't know is just how reliably weight loss with high protein diets can be predicted. We do know that some people have lost a lot of weight on high protein diets. We also know that a lot of people have not lost weight on high protein diets. Probably a greater majority just can't stand to eat nothing but protein for a prolonged period of time. The reason I mention that is that weight loss is generally recorded in the first month or two of high protein diets.
High Protien Diet
Another thing we know is that among those who have lost a lot of weight, there are also signs of dehydration or at least a lack of bloating. That may be why the weight loss ceases after a period of time. After all, you can only give up so much water.
The interesting thing here is that on standard diets, which consist of balanced diets, weight loss is much slower, but continues on as long as the person keeps the total calorie count down. Many do give up, however, because at times weight loss may be so slow as to be unnoticeable. However, those who stick with it a long time come to realize that the weight loss does continue even when it is unnoticeable.
Weight loss with high protein diets seems to have an opposite psychological effect. A bunch of weight is lost right away when beginning the high protein diets. The encouraged dieter is led to continue, but suddenly notices the weight loss has stopped. Tired of the limited diet plan, the discouraged dieter usually quits the high protein diet right away.
Unproven theories about how weight loss composition occurs may have been the most damaging part of the development of high protein diets. For example, one theory was that you would lose less muscle on a high protein diet because your body wouldn't need to break down as much protein from your body to burn as energy. But when someone tried to back that up with a study, the results showed the opposite. People who ate balanced diets while dieting had a slightly lower percentage of their weight loss occur as a result of muscle loss. The theory of weight loss by ketosis when eating only fats and proteins has also come from questionable amounts of evidence.
Mankind just isn't designed to exist on one type of nutrient. Our bodies are designed to use a wide variety of nutrients, and dysfunction well when missing any of them. So you should definitely consult at least your doctor, and probably a nutritionist as well, before you begin any extreme diets, such as high protein diets.
