Weight Loss Advertising Rules on Facebook

Quick Answer

Meta bans before-and-after weight loss images, ads implying body insecurity, and ads targeting users 18 or under for diet, weight loss or weight management products. The FTC's Weight Loss Claims guidance enforces strict evidence standards and the ASA in the UK has banned hundreds of weight loss ads. GLP-1 medications (Ozempic, Wegovy, Mounjaro) face additional restrictions as prescription drugs.

What the rule actually says

Meta's personal attributes policy and ad standards prohibit:

• Before-and-after images for weight loss, beauty or any health transformation.
• Negative body imagery or content that creates body insecurity.
• Targeting minors with weight loss content.
• Unrealistic outcomes implied by the creative.
• Idealised body imagery.

FTC rules and the seven 'gut check' claims warn against weight loss promotions that promise:

• Weight loss of two pounds or more per week without diet or exercise.
• Substantial weight loss no matter what or how much the user eats.
• Permanent weight loss even after stopping the product.
• Blocks fat or calories.
• Substantial weight loss for all users.
• Weight loss by wearing or applying to the skin.
• Weight loss greater than 20 pounds for the average user.

ASA rules in the UK ban any ads that promote dangerously thin body types, target under-18s, or make unsupportable health claims.

What is allowed and what is banned

Allowed: gym memberships, fitness apps and healthy lifestyle content with realistic before-and-after-style framing (where Meta permits), nutrition coaching from qualified providers, and prescription weight loss medications from licensed pharmacies (with prior Meta approval).

Banned: before-and-after weight loss imagery, targeting minors with diet content, unsupported claims, body shaming, GLP-1 ads without pharmacy authorisation, miracle product claims, and weight loss product ads that imply rapid or guaranteed results.

Step-by-step compliance setup

1. Audit creative for before-and-after framing and remove or restructure.
2. Frame messaging around health, fitness and lifestyle rather than body dissatisfaction.
3. Target users 18+ and exclude minors from weight management campaigns.
4. For GLP-1 ads, apply for Meta's pharmaceutical/restricted category approval.
5. Substantiate every claim with peer-reviewed evidence and document the basis.
6. Add appropriate disclaimers (results not typical, individual results vary).
7. For prescription products, comply with local pharmaceutical advertising rules (FDA DTC for US, MHRA for UK).
8. Avoid linking to clickbait or sensationalised landing pages.
9. Comply with Meta's quality and integrity policies (no fake testimonials).
10. Train marketing staff on personal attributes and prohibited claims.

Frequently asked questions

Can I show a person's body in a fitness ad?
Yes, but in a healthy, lifestyle-oriented way. Avoid framing that implies the viewer should feel bad about their body.

Are GLP-1 ads allowed?
They require Meta's restricted category approval, must come from a licensed pharmacy or telehealth provider, and must comply with FDA direct-to-consumer drug advertising rules.

Can I use the word 'transformation'?
Yes, but framed around health and lifestyle. Avoid imagery showing dramatic body transformation.

Is intermittent fasting content allowed?
Lifestyle and educational content is generally allowed. Specific weight loss claims require evidence.

What is the FTC's gut check standard?
A list of seven claims the FTC considers facially false and not credible regardless of evidence offered.
