In adults with overweight or obesity who have already lost weight, anti-obesity medications significantly prevent weight regain and produce additional weight loss of approximately 8.68 kg over the maintenance phase compared to placebo, improving long-term metabolic health outcomes.

Why this might work

The brain reduces hunger signals and increases how many calories the body burns, causing fat stores to shrink even after weight loss has already happened.
