Can You Advertise Weight Loss Products on Facebook?

Weight loss is one of the categories Meta allows with conditions rather than bans. The conditions fall into two groups. Eligibility depends on what you sell: a supplement, a programme, a wearable, a prescription drug or a cosmetic procedure each sits under a different rule. Creative rules then decide what the ad may say and show, and most rejections in this category come from the creative, not the product.

Which weight-loss products can you advertise on Facebook?

Most of them, at 18+. By product type:

The unsafe-substance row is the one stores miss. Meta’s Help Center list of unsafe substances includes anabolic steroids, chitosan, comfrey, dehydroepiandrosterone, ephedra and human growth hormones, and says the list is not limited to those. One of its own rejected examples is a human growth hormone pill sold as making weight loss easier (About Meta’s Drugs and Pharmaceuticals advertising policy). Check the ingredient list before you build the ad.

What can a weight-loss ad say and show?

Four creative rules name weight-loss ads directly; the first also covers cosmetic ads and the last also covers health ads (About Meta’s Health and Wellness advertising policy):

1. No statements of inferiority about appearance. Meta defines them as terms, descriptions or questions that are negative and attack a person’s appearance, specific body parts or hygiene. “Tired of your belly fat?” attacks; “A protein shake with 20 g of protein and 2 g of sugar” describes.
2. No fat-pinching close-ups. Meta bans depicting a close-up on a specific body area with pinched fat.
3. No wearable-only results. An ad cannot claim results come solely from using a wearable product.
4. No clickbait. No sensational language with exaggerated or extreme claims, and no promise of a specific outcome within a set timeframe without a disclaimer or qualifier.

What Meta does allow, at 18+, is showing people using the product, its impact, and a clear indication of the time it took to get noticeable results. Meta’s summary of the policy describes it as prohibiting ads that “generate a negative self perception or imply unrealistic or unexpected results” (About Meta Advertising Standards). Result photos have their own rules; see can I use before-and-after photos in Facebook ads?

The example copy above is ours, not Meta’s. The nutrient figures are placeholders: use your own label.

How do I set up a weight-loss ad that gets approved?

1. Check every ingredient against Meta’s unsafe-substances list, and drop products that contain one.
2. If the product needs a prescription, stop and apply for Meta’s written authorization before building the ad.
3. In Advertising settings, click Audience controls, toggle on “My business sells or advertises age-restricted goods or services” and set the Minimum age to 18 or older.
4. In Ads Manager, open the ad set, find Audience, and confirm Minimum age under Controls shows 18 or older.
5. If the ad uses the WhatsApp Status placement, deselect Unknown age on WhatsApp in Audience controls.
6. Rewrite any line that comments on the viewer’s body, and put a qualifier next to every timeframe.
7. Replace fat-pinching or body-part close-ups with full shots of the product in use.

Step 3 follows Set audience and placement controls for your ad account, which Meta is still rolling out, so you may not see it yet. Step 4 follows Create a campaign using Advantage+ audience, where Meta says a minimum age set in Audience controls can’t be overruled. Step 5 matters because Meta says the WhatsApp Status placement includes people whose age is unknown, and ads shown to them must suit all ages (Age and gender targeting).

Do I need authorization to advertise GLP-1 or other weight-loss drugs?

Yes, if the product requires a prescription. Meta’s Health and Wellness policy sends prescription weight-loss products to its Drugs and Pharmaceuticals policy, with its geo-targeting and written-permission requirements. That policy lets only qualified advertisers run prescription drug ads: online pharmacies and telehealth providers need active LegitScript certification, pharmaceutical manufacturers can go through Meta’s internal review, and the ads must target people 18 or older in the United States, Canada or New Zealand, and only where the advertiser is certified (Drugs and Pharmaceuticals).

Our reading: because the rule turns on the advertiser’s certification and Meta’s authorization, a seller without them cannot advertise a prescription weight-loss drug in any form. If you are unsure whether your product counts as prescription, ask a pharmacist or lawyer before you build the ad.

How is this different from general wellness ad rules?

The 18+ rule and the ban on curing listed diseases cover dietary, health and cosmetic products broadly; those are covered in what are Meta’s ad rules for wellness products? What is specific to weight loss is the list above: fat-pinching, wearable-only claims, the timeframe qualifier in a weight-loss context, and the route for prescription weight-loss drugs.

Can software help?

Bach.ai connects to your Meta ad account, audits it daily and estimates the revenue impact of what it finds, and it reports a disapproved ad as a policy blocker rather than weak performance. It applies changes on Meta only after you approve them. Ingredient checks and any authorization request stay with you; for the wider policy review, use the Facebook ad policy guide.

FAQ

Can I target under-18s with a weight-loss ad?

No. Meta’s Health and Wellness policy says ads promoting dietary, health, weight-loss or weight-gain products and services must target people at least 18 years old. Set the minimum age in Audience controls, where Meta says it can’t be overruled, and remove the unknown-age WhatsApp audience if you use that placement.

Can a weight-loss ad say “lose 10 pounds in 30 days”?

Only with a disclaimer or qualifier next to the claim. Meta treats promises of specific outcomes within a set timeframe without disclaimers or qualifiers as clickbait in a weight-loss context. Even qualified, the result must be one customers can expect; how to evidence it is a separate job from getting it approved.

Are slimming belts and sauna suits allowed?

They can be advertised to people 18 and over, but the ad cannot claim that results come solely from using the wearable. Show the product as part of a routine, such as exercise, and avoid close-ups that pinch fat or copy that is negative about the wearer’s body.

Can fitness ads show weight loss?

Meta’s own Help Center marks an image that focuses on physical fitness as compliant. Once the ad promotes a weight-loss product or service, the weight-loss rules apply: 18+ targeting, no statements of inferiority, no fat-pinching close-ups and qualified timeframes.
