Fad diets are not the best way to lose weight and keep it off. Fad diets often promise quick weight loss or tell you to cut certain foods out of your diet. Weight loss may happen initially on one of these diets. But they are hard to follow and the tendency is to get tired of them and regain any lost weight.
Fad diets can also be unhealthy because not all of the nutrients your body needs are provided for. Also, losing weight at a very rapid rate are unhealthy. Diets that provide less than 800 calories per day also could result in heart rhythm abnormalities, which can be fatal.
No foods can burn fat. Some foods with caffeine may speed up the body’s metabolism for a short time, but they do not cause weight loss.
A pound of fat contains 3,500 calories. To lose weight try reducing caloric intake by 350-500 calories along with exercising each day (burning about 350 to 500 calories). This will provide for a reasonable and maintainable weight loss through life style change.
