Hormonal

Lifestyle interventions alone are often insufficient for long-term weight maintenance due to hormonal and metabolic adaptations that drive weight regain, necessitating adjunctive therapies for many patients.

If you regain weight after lifestyle changes, do not blame yourself. Your body's hormones and metabolism are adapting to store energy. This is a common biological response, and it is why medical guidelines recommend considering additional therapies (like medication) if lifestyle changes alone do not sustain your results.

GoodRefutesHIGH confidence
most individuals are unable to sustain their weight loss achieved via lifestyle interventions alone, often regaining more than half of the weight lost within 2 years and more than 80% within 5 years... largely driven by hormonal and metabolic adaptations that occur to compensate for the initial weight loss.
