When people go on diets, they often disconnect from natural body responses, such as hunger, shifting their focuses to caloric guidelines. This can lead to a life that revolves around dieting. Dieting can make food the enemy so that you feel guilty when you eat it. Even worse, restricting foods can cause cravings for them, which can lead to yo-yo dieting. Dieting can have many consequences including damaged health, increased risk of obesity and side effects resulting from nutritional deficiencies.
