Common myths about dieting and weight loss include beliefs like "carbs are bad" or "skipping meals accelerates weight loss." In reality, carbohydrates are a crucial energy source and skipping meals can slow metabolism and lead to overeating later. Another myth is that more exercise alone guarantees weight loss; nutrition plays an equally important role. Additionally, some people believe that detox diets or supplements are effective for weight loss, but they often lack scientific backing. Understanding these myths is essential for a balanced approach to healthy eating and maintenance of a healthy weight.
