Adherence

Structured behavioral interventions (diet, exercise, lifestyle counseling) are effective for modest weight loss and diabetes prevention in overweight/obese adults, whereas routine pharmacologic interventions (orlistat, metformin) are not recommended due to adverse event profiles outweighing benefits.

Focus on sustainable lifestyle changes (diet, exercise, counseling) rather than seeking quick fixes like weight-loss drugs. Behavioral interventions provide modest but clinically meaningful weight loss (approx. 3 kg) and diabetes prevention with fewer side effects than medications. Consult your primary care provider for a structured program.
