GLP-1 vs Lifestyle-Only Weight Loss

GLP-1 therapy produces 12–20% mean weight loss; lifestyle-only typically produces 3–8%. Lifestyle remains the foundation under both pathways, and combined therapy is the most durable provider-reviewed approach.

Choose GLP-1 therapy

GLP-1 therapy is the provider-reviewed pathway when BMI thresholds and metabolic risk indicate pharmacologic support, combined with lifestyle.

Choose Lifestyle-only

Lifestyle-only is the appropriate pathway for candidates below pharmacologic thresholds or when GLP-1 is contraindicated.

Educational. Final pathway selection is provider-reviewed via synchronous video consultation against your biomarkers, history, and goals.

Frequently asked

Do I need lifestyle change on a GLP-1?

Yes — protein intake, resistance training, and sleep determine body composition outcomes.

What happens when GLP-1 is stopped?

Weight regain is common without sustained lifestyle infrastructure.
