Care must be taken to make sure that you are getting enough of all essential nutrients. A diet of less than 1000 calories for women and 1200 calorie for men is likely to led to nutritional deficiencies. Your diet plan must be individually planned by a nutritionist or dietician based on your current health status and requirements. Nowhere is hucksterism more evident than in the promotion of crash diets. Going on and off diets, losing weight, gaining it back giving up and feeling desperate are situations faced by many of those trying to lose weight.
Many people live in a polarised state of feast or famine.
The truth is that crash diets will not keep anyone thin. This makes the cure rate for overweight worse than that for cancer. The only winners are those who become rich by promoting these fads and gimmicks to a nutritionally naive and diet-obsessed public. The only way to lose weight safely and effectively is through dietary reductions and increased physical activity. Every fad diet is unbalanced in one way or another and many are downright dangerous, even if followed by relatively healthy people for a short time.
