Fad diet
From W8MD weight loss and sleep centers
Fad diet - a fad diet is a diet that is popular for a short period of time but lacks scientific evidence to support its claims or is not a sustainable long-term dietary plan. Fad diets often promise rapid weight loss, but they may not provide a balanced and nutritious diet and can be harmful to health. Examples of fad diets include the cabbage soup diet, the grapefruit diet, and the juice cleanse diet.
