"If you have ever struggled to lose weight only to see the pounds creep back, you are not alone, and it is not your fault. The frustrating cycle of weight loss and regain is not a personal failure but a biological one, with your own brain actively working against your efforts. Modern science reveals that our bodies are evolutionarily wired to defend a certain weight level, treating weight loss as a threat to survival."
"For our early human ancestors, storing fat was a key to survival during periods of famine. The human body evolved powerful mechanisms to protect these energy reserves. Today, in a world of abundant food, these same ancient survival systems sabotage modern weight loss goals. Your brain establishes a "set point" weight range and deploys a host of defenses to maintain it."
"When you lose weight, your body reacts as if it is under threat. "Every time there's an opportunity, your body will try to defend you from losing weight because it's trying to protect you from starvation," says endocrinologist and obesity specialist Marcio Griebeler, MD. This defense is not passive; it is a vigorous biological counterattack. The body's defense mechanisms The assault is hormonal."
Human bodies evolved mechanisms to defend a favored weight range, treating fat loss as a starvation threat. The brain sets a 'set point' and activates hormonal and metabolic defenses when weight falls. Weight loss increases appetite hormones (for example, ghrelin) and lowers resting metabolic rate, which amplifies hunger and conserves energy. Obesity is primarily a biological condition shaped by evolutionary pressures and modern food abundance rather than a moral failing. Effective responses address underlying biology through nutrient-dense diets, strength training to preserve lean mass, adequate sleep, and stress management. Repeated weight regain reflects physiological defenses, not personal weakness.
