Hormonal

Lifestyle interventions for obesity typically result in modest long-term weight loss (5-10%) and high rates of weight regain due to potent biological adaptations, specifically increased appetite and reduced energy expenditure.

If you lose weight through diet and exercise, expect your body to fight back with increased hunger and a slower metabolism. This is a normal biological response, not a failure of willpower. To maintain loss, you may need ongoing support or pharmacological intervention to counteract these specific hormonal signals.
