In addition to the above, fast weight loss diets have many other side effects. For starters, when you suddenly change your diet and start eating less than normal this may trigger your body's starvation response. When this occurs your body wants to conserve its energy and doesn't want to let go of your body fat, which means your fat loss will slow down to a halt. Another factor to consider is that it is very likely that you will re-gain any weight you lost on a fast weight loss diet when you complete your diet. This is due to the extremely restrictive nature of low-carb diets which can result in cravings and subsequent binges as you fall back into your old way of eating, and is also due to the muscle loss which slows down your metabolism. Some fast weight loss diet programs promise very optimistic results but charge you lots of money for the shakes and food bars which are a "necessary" part of the program. What's more, 95% of dieters put the weight they lose back on, and end up going back on a diet. How would you feel if you invested hundreds of dollars every month on a fast weight loss diet, and then put it all back on when you got off the diet? The key to successfully and permanently losing the fat is not to drastically lower calories, nor to label carbs as evil and avoid them like the plague, as many fast weight loss diets advocate. Instead, you will get more.
