Extreme dieting can have several potential downsides, including nutritional deficiencies and negative metabolic impacts. Restrictive diets often limit essential nutrients, leading to energy depletion and potential health complications. With inadequate caloric intake, the body may enter starvation mode, slowing metabolism and making weight loss more difficult. Emotional consequences, such as increased stress and a negative relationship with food, can also arise. Sustainable changes to eating habits that prioritize balance and moderation are far superior to extreme diets for long-term health and well-being.
