Girls, Listen. Eating less than 1200 calories is seriously unhealthy.
While these diets may appear to work, they are actually extremely ineffective. Most of the weight you lose initially is water weight, not fat. This happens because when your body is given only a small amount of calories, your body gets the energy it needs from glycogen stores. Glycogen holds water, so when it is burned the water is released.
Low calorie diets also mean that your body will go into starvation mode, where metabolism slows down and muscle is lost as your body begins using muscle for energy. Your body also will hold onto fat as an energy store. Also, when you return to normal eating your body now has a slower metabolism and less muscle meaning that you are likely to gain back the weight or even more than before the diet.
Diets like this can even cause an obsession with calories and fitness that could potentially develop into an eating disorder. You do not want an eating disorder. It is not glamorous or fun. It is a serious illness and it can be life threatening. Ask any one who has ever experienced one and they will tell you that they are horrible and not something that any one should ever want or aim for.
If you want to lose weight, then the only way to do it is through healthy eating and exercise. Developing a healthy lifestyle is hard and takes time, but the benefits are great. Not only will you achieve permanent weight loss and a strong, lean, beautiful body; you will be happier, more energetic, your skin will glow, your hair will be shiny, your nails will be strong, you will become more confident and you will be proud of your body.
