Average Weight Loss on Ozempic (What Studies Show)
In people with type 2 diabetes, Ozempic-dose semaglutide produces modest-to-moderate average weight loss, with higher doses generally associated with somewhat greater reductions. In the 40-week SUSTAIN FORTE trial, participants receiving semaglutide 2.0 mg lost an average of about 6.9 kg, compared with about 6.0 kg with 1.0 mg among participants who remained on treatment without rescue medication. Weight loss varies substantially between individuals, and body-weight change was a secondary confirmatory outcome in this diabetes trial.
People without diabetes have generally lost a higher percentage of body weight in semaglutide obesity trials, but these studies usually used 2.4 mg weekly - the weight-management dose marketed as Wegovy, not an Ozempic dose. In STEP 1, adults without diabetes receiving semaglutide 2.4 mg plus lifestyle intervention lost about 14.9% of body weight on average at 68 weeks. These results should not be treated as typical Ozempic outcomes.
There is no single percentage of weight loss that applies to everyone taking Ozempic. Results depend on dose, diabetes status, treatment duration, baseline weight, adherence, tolerability, and other clinical factors. Trial averages are useful for context but should not be treated as a personal prediction.
