Proponents of Low-carbohydrate diets claim that in order to lose weight, a person should severely lower his carbohydrate intake so that the body goes into a ketogenic state. That's when the body feeds off of body fat for energy. However, researchers discovered that people on low-carb diets do not really lose actual body fat, instead they lose muscle glycogen which quickly leads to muscle loss (this also happens to people on low-calorie diets). (The body stores carbohydrate, mostly in your liver and muscles, in the form of glycogen.) Low Carb Dieters also lose water weight since glycogen carries a lot of water. For this reason, people look slimmer when going on low-carb diets. However, after losing the initial 5-10 pounds, weight loss may begin to stagnate. If the diet is continued over a period of weeks or months serious side effects can ensue.
The problem with the theory that people must enter the ketogenic state to lose weight, is that fat burns much more slowly that carbohydrate. This means that if you’re on a strict low carbohydrate diet, you can say goodbye to weight training or any strenuous physical activity. But these activities add lean muscle to your body and boost your metabolism! The way it works is that being in the ketogenic fat burning mode promotes a slow and sluggish metabolism, for this reason people usually gain the weight right back when then stop the diet and in fact suffer from slow metabolism for months or years to come, making weight loss even harder in the long term.
When you deplete muscle glycogen, there is an increase in muscle fatigue, and also an increase in muscle catabolism (direct metabolism of your body’s own muscle protein). Many people on a low-carbohydrate diet simply stop exercising, because it can suck up so much energy. The theory behind the low carb diet simply makes no sense and even more concerning is that is can lead to muscle weakness, brittle bones, depression, mental deterioration, kidney disease, fatigue, severe digestive distress, and reduce immunity (susceptabilty to disease).
Also concerning is the high amounts of animal protein and dairy consumed by low carb dieters. Over-consumption of animal protein including red meat, chicken and fish severely taxes the kidneys, the heart, and the digestive system. The liver can break down some of the protein, but the body has to store the rest of the protein somewhere. The excess protein is converted into collagen fiber built into the basal membranes of the capillary walls. Collagen is 100% pure protein. This res
