Short answer: A weight loss ad on Meta can only reach people 18 and over. It can’t attack how anyone looks, zoom in on pinched fat or promise a specific outcome within a set time without qualifiers. Google doesn’t accept ads that claim unrealistic weight loss in a set time or with little effort. The FTC asks that a testimonial show typical results, or that the ad say clearly what they are.
Before you read: Here is what Meta, Google, the FTC and the FDA publish about weight loss ads, for clinics that sell weight loss programs. This is general information, not legal advice. Review each ad, page and testimonial with your medical director and your attorney.
What Meta allows in a weight loss ad
Under its health and wellness policy, Meta requires that any ad for a weight loss product or service be aimed at people aged 18 or older.
Those ads also can’t make statements of inferiority, which Meta defines as negative words, descriptions or questions that attack a person’s looks, a specific body part or hygiene.
For weight loss, Meta also rules out close ups of a body area where fat is being pinched, and claims that a wearable product alone brings the result.
In a health or weight loss context, Meta treats sensational language with exaggerated or extreme claims as clickbait. So is a promise of a specific outcome within a set time with no disclaimers or qualifiers.
Aimed at adults, Meta’s policy allows ads that promote “dietary weight loss or weight gain products and services such as supplements or pills”. For those, “the ad can illustrate people using the product or the service, and its impact of using it”. It can also “clearly indicate the time taken to achieve noticeable results”. The policy page doesn’t say whether a clinic’s medical weight loss program falls under that line.
Meta’s rules on personal attributes add a limit on copy: an ad can’t imply that the advertiser knows medical information about the viewer. Among Meta’s own examples, “Do you have diabetes?” is turned down and “New diabetes treatment available” is accepted. In our view, “Struggling with your weight?” is the same kind of question, so write about the program.
A weight loss product that needs a prescription must also meet Meta’s drugs and pharmaceuticals policy. That policy sets its own rules on where the ad can run and on written permission.
Google turns down unrealistic weight loss claims
Google’s unreliable claims policy doesn’t allow claims of unrealistic weight loss within a specific time frame or with little effort. Extreme weight loss products or programs are on its list of examples.
Its specific example is a weight loss ad that says you can eat whatever you want and lose 10 pounds in a month.
Testimonials that claim specific results need a visible disclaimer saying that no specific result is guaranteed and that results can vary. An ad that guarantees a result needs a refund policy that is clear and easy to find.
Google sends a warning at least 7 days before it suspends an account under this policy. If it happens anyway, our Google Ads suspension guide explains how to appeal.
In personalized advertising, Google counts some health content as a sensitive interest category. Its list names injections and the products, services or procedures that treat chronic health conditions. Those ads may reach predefined Google audiences, not audiences the advertiser curates, such as a client list.
In our view, if your weight loss program is built on injections, run its Google campaigns with predefined Google audiences only. Our guide to IV therapy marketing covers what IV drip ads can claim on Google and Meta.
What the FTC expects from testimonials and photos
For weight loss products, the FTC says advertisers need scientific proof for the objective claims in their ads before the ads run.
It adds that false or misleading claims can come through words or images, and it names eye-catching before-and-after pictures among them.
The FTC’s rules on endorsements apply to all weight loss products, programs and services. Either the results in the ad are typical of what other people can expect, or the ad discloses the typical results clearly and conspicuously.
As a rule, a testimonial of more than 15 pounds in all should come with a disclosure of how much weight people can typically expect to lose. The same goes for two pounds or more a week for a month or more. Writing “results not typical” or “your results will vary” is not enough.
A clear and conspicuous disclosure sits close to the claim, in an easy-to-read font and a shade that stands out from the background, in words people understand. In a video, it stays on screen long enough to be read.
In our view, a weight loss testimonial that runs on Google needs both lines: Google’s note that results can vary, and the typical result the FTC asks for.
The FTC’s list of seven “gut check” claims includes weight loss for every user and weight loss that lasts after the product is stopped. The list is written for supplements, over-the-counter drugs and products worn on the body or rubbed into the skin, not for prescription drugs or special diets. In our view, it still marks what a clinic should never promise.
Our HIPAA social media guide covers the written authorization a patient’s photo or testimonial needs before it appears in an ad.
Compounded GLP-1 drugs in your ads
The FDA says compounded drugs are not FDA approved, so it doesn’t review them for safety, effectiveness or quality before they are marketed. That includes compounded semaglutide and tirzepatide.
The FDA’s red flags for people buying from telehealth companies include a claim that a compounded drug is the same as an FDA-approved drug. Prices that seem too good to be true are on the list, and so is medicine provided with no screening and prescription by a licensed doctor.
Retatrutide and cagrilintide can’t be used in compounding under federal law. The FDA has warned telehealth companies for marketing unapproved drugs such as retatrutide, including direct marketing to consumers.
In our view, neither the ad nor the page of a compounded GLP-1 program should present the drug as the same as an FDA-approved one. Nor should either lead with a discount that looks too good to be true.
Google lists semaglutide and tirzepatide among the prescription drugs it monitors. It restricts ads for services related to the online prescribing, dispensing and sale of prescription drugs, and advertisers need its certification to serve them. Some certifications may first need accreditation from a third party such as LegitScript. Meta requires online pharmacies and telehealth providers to be actively certified with LegitScript, and then to request Meta’s authorization.
Our Botox advertising guide has a section on semaglutide and tirzepatide programs.
Checking a weight loss ad before it runs
- On Meta, make 18 the minimum age for every weight loss ad.
- Take out of the copy and the images any claim of unrealistic weight loss within a set time or with little effort.
- Next to each testimonial, put the typical result and Google’s note that results can vary.
- Replace questions about the viewer’s weight with lines about your program and your team.
- Check that no ad or page presents a compounded drug as the same as an FDA-approved one.
Steps 1 to 3 follow Meta’s, Google’s and the FTC’s rules. Steps 4 and 5 are our advice, based on Meta’s rules on personal attributes and the FDA’s red flags.
Before a weight loss campaign goes live
- Every Meta weight loss ad has 18 as its minimum age.
- No ad claims unrealistic weight loss within a set time or with little effort.
- No image zooms in on fat being pinched.
- Every testimonial has the typical result next to it.
- No line asks about the viewer’s weight or health.
- No ad or page calls a compounded drug the same as an FDA-approved one.
RememberAim weight loss ads at adults and write about your program, not the viewer’s body. Leave out unrealistic weight loss tied to a date or to little effort. Put the typical result next to every testimonial, and never present a compounded drug as FDA approved.

Common questions about weight loss ads
Can a weight loss ad show before and after photos?
Meta’s policy covers “dietary weight loss or weight gain products and services such as supplements or pills”. For those, “the ad can illustrate people using the product or the service, and its impact of using it”. The page doesn’t say whether a clinic’s medical program falls under that line. No weight loss ad can zoom in on pinched fat. The FTC names before-and-after pictures as one way to mislead.
Can a weight loss ad promise a number of pounds in a month?
Google doesn’t allow claims of unrealistic weight loss within a specific time frame; its example is losing 10 pounds in a month while eating whatever you want. Meta counts a promise of a specific outcome within a set time, with no disclaimers or qualifiers, as clickbait. In our view, keep both the pounds and the date out of the promise.
Is “results may vary” enough under a testimonial?
Not for the FTC, which says “results not typical” or “your results will vary” is not enough and asks for the typical result. Google requires testimonials that claim specific results to carry a visible disclaimer that results aren’t guaranteed and can vary. In our view, use both lines.
Can I advertise compounded semaglutide?
Google lists semaglutide and tirzepatide among the prescription drugs it monitors and requires certification for ads for prescription drug services. On Meta, a weight loss product that needs a prescription falls under the drugs policy, which requires online pharmacies and telehealth providers to be actively certified with LegitScript. The FDA says compounded drugs are not FDA approved. In our view, never call it FDA approved.
Can a weight loss ad ask about the viewer’s weight?
On Meta, an ad can’t imply that the advertiser knows medical information about the viewer, and “Do you have diabetes?” is one of the lines its examples turn down. In our view, a question such as “Struggling with your weight?” runs the same risk. Write about your program, your team and what a visit includes instead.
