However,before you bring home loads of chicken ,nuggets , kebabs and eggs , you may want toconsider a few things:1. Low carb (ketogenic) diets deplete and you exercise and move less (often without realizing it) which is not good forthe healthy glycogen (the storage form of caloric expenditure and basal metabolicglucose) stores in your muscles and liver. rate (metabolism).When you deplete glycogen stores, youalso dehydrate, often causing the scale to 3.

Some proponents of low carbdiets recommend avoiding carbohydratessuch as bread, pasta, potatoes, carrots, etc.because of they are high on the glycemicindex - causing a sharp rise in insulin.Certain carbohydrates have always been,and will always be the bad guys: candy,cookies, baked goods with added sugar,sugared drinks, processed / refined whitebreads, pastas, and rice, and any foodswith added sugar. These are not good forhealth or weight loss. However, carbohydrates such asfruits, vegetables, legumes, wholegrain breads and pastas, and brownrice are good for health and weightloss. Just like with proteins and fats,these carbohydrates should beeaten in moderation. Largevolumes of any proteins, fats orcarbohydrates are not condu-cive to weight loss and

Weight loss (mostly muscle and muscle fluid) is often rapid during the first fewweeks. This causes people to think they’re losing fat rapidly.B. It gives you "permission" to eat the "bad foods": eggs, fried chicken, steak, cheese,etc., and lots of fat.C.
