The Real Reason It's So Hard to Lose Weight

Losing weight is challenging due to the body's resistance, driven by hormonal changes. Hormones like leptin and ghrelin play a significant role in regulating appetite and energy conservation. The body becomes more energy-efficient during dieting, making it harder to lose weight. Even after returning to normal eating, hormonal changes can persist, leading to weight regain. Studies show that metabolic rates drop after weight loss, requiring more effort to maintain or lose weight again. Individual responses to dieting vary, influenced by genetics and other factors.
