Common myths about weight loss and dieting include the belief that certain foods can "burn fat" or that restrictive diets are the only way to lose weight. Another prevalent myth is that skipping meals leads to faster weight loss, when in fact it can slow metabolism and lead to overeating later. Sustainable weight loss is usually achieved through a balanced approach combining healthy eating, regular physical activity, and making long-term lifestyle changes rather than relying on quick-fix diets.
