Weight loss triggers several physiological adaptations that can make maintaining reduced body weight challenging. The body responds to calorie restriction by adjusting energy expenditure, appetite, and hormone levels, often promoting weight regain.Key Points:Reduced Resting Metabolic Rate (RMR): Energy expenditure decreases as body mass drops.Hormonal Changes: Levels of leptin, ghrelin, and thyroid hormones shift, increasing hunger and decreasing satiety.Adaptive Thermogenesis: The body becomesmore efficient at conserving energy, slowing weight loss.Behavioral Impact: Increased appetite and cravings can challengeadherence to dietary changes.Management Strategies:Gradual, sustainable weight loss rather than rapid restriction.Incorporation of resistance training to preserve lean muscle mass.Ongoing behavioral and dietary support to maintain lifestyle changes.Understanding metabolic adaptations helps design effective long-term weight management strategies and prevents weight regain.
