Why is losing 20 lbs so hard?

Losing 20 pounds is challenging because it requires consistent lifestyle changes over several months. Your body naturally resists weight loss to protect against starvation. As you lose weight, your metabolism slows slightly and hunger hormones increase. Other factors include emotional eating habits, busy schedules, food environments, stress, lack of sleep, and the difficulty of breaking old patterns. Success requires patience, consistency, and addressing both physical and emotional aspects of eating.
