Fad Diets are Unhealthy
Some fad diets focus on one particular food or type of food. Other fad diets are fasting-type-diets and limited in duration to a few days.
This is bad diet-nutrition. The No 1. rule of good diet nutrition is:
Eat a balanced diet that includes a variety of foods.
Fad diets may cause you to develop nutritional deficiencies, because no one type of food has all the nutrients necessary for good health.
In particular, beware fad diets that promote “fat-burning” foods. There are no foods that have special “fat-burning” properties.
That’s why you should eat moderate amounts from all food groups, not large amounts of a few special foods.
Fad dieting can sometimes lead to weight-cycling or yo-yo dieting – i.e. weight loss, followed by regain, followed by weight loss then regain etc. New research suggests that such weight cycling may lead to obesity.
So, avoid fad diets and fad dieting. Instead, pay attention to the Food Pyramid Guidelines and eat a balanced diet that includes foods from ALL food groups.
