Short answer: Meta allows weight loss ads on Facebook and Instagram, including before and after results, as long as the ad targets people 18 or older and follows four framing rules. Its current Health and Wellness standard says a dietary weight loss ad "can illustrate people using the product or the service, and its impact of using it, and clearly indicate the time taken to achieve noticeable results." What gets rejected is the copy around the transformation: attacks on how the viewer looks, fat-pinching close-ups, wearable-only claims, and a set result in a set time with no qualifier.
That last sentence matters more than the first one. Most rejected weight loss ads were never going to fail on the product. They fail on a single line of voiceover or one close-up that the creator improvised on the day, because nobody told them what the policy says.
A disclosure before the rules. We sell a generator that writes ad briefs and on-camera scripts, including the brief for a before and after ad. We do not buy media, submit ads to Meta or supply creators, so we have no stake in which agency or platform you use. Everything attributed to Meta and the FTC below was read on their own pages in September 2026 and is quoted word for word.
Can you run weight loss ads on Facebook?
Yes. Meta lists "Ads promoting or marketing dietary, health, or weight loss or weight gain products" as a restricted category, not a prohibited one. Restricted means you can run them with conditions attached. The first condition applies to everything in the category: the ad "must be targeted to people at least 18 years or older." Set the age floor in the ad set before you do anything else, because an ad that is fine on every other count is still rejected if it can reach a 17-year-old.
Here is how the standard sorts the products a weight loss brand is likely to sell. The quotes come from Meta's Health and Wellness page on its Transparency Center, whose change log shows its most recent entry in July 2026.
| What you sell | Can you advertise it? | What Meta's text says |
|---|---|---|
| Supplements, pills, shakes, meal plans sold for weight loss | Yes, 18+ only | "Dietary weight loss or weight gain products and services such as supplements or pills. The ad can illustrate people using the product or the service, and its impact of using it, and clearly indicate the time taken to achieve noticeable results." |
| Prescription weight loss drugs, including GLP-1 telehealth | Only under a separate policy | "For weight loss products that require prescription, please refer to Drugs and Pharmaceuticals ads policy" |
| Gyms, fitness classes, equipment, workout apps | Yes, and the 18+ floor does not apply | Exempt as "Products and services marketed for general wellbeing, such as fitness services and equipments" |
| Protein bars, powders, general food | Yes, and the 18+ floor does not apply | Exempt as "General food products, including protein products" |
Notice the fitness exemption. A personal trainer or a gym selling a transformation program is advertising a fitness service, not a dietary product, and it sits outside the age requirement. The moment the same trainer bundles a fat burner into the offer, the ad moves into the dietary row.
Are before and after pictures allowed in weight loss ads on Facebook?
Yes, and this is where a lot of the advice ranking for this topic is out of date. Several of the pages you will find tell you flatly not to use before and after images in weight loss ads. Meta's own current wording says the opposite for dietary products: the ad can show "its impact of using it" and should "clearly indicate the time taken to achieve noticeable results." That is a description of a before and after ad with a stated timeline.
What the text does not allow is the bad version of the format. The four restrictions below all describe how a transformation is framed, not whether you may show one. So the practical job is not avoiding the format. It is scripting it so the before shot shows the problem without insulting anyone, the timeline is on screen, and the result is one a typical buyer can expect. Our before and after ads brief is built around exactly those three things.
What gets a weight loss ad rejected on Facebook?
Four patterns, each named in Meta's text. Here they are next to the kind of line a creator ad-libs and a version a reviewer has nothing to object to.
| Meta's restriction (verbatim) | Line that trips it | Line that doesn't |
|---|---|---|
| "statements of inferiority about physical appearance (i.e., terms, descriptions, or questions that are negative and attack an individual's appearance" | "Tired of hiding your belly fat?" | "I wanted something I could stick to on a work schedule." |
| "Close up on specific body area by pinching fat" | A hand gripping a stomach in the before shot | A mid-shot of the creator, same angle and light as the after shot |
| "Claims that results can be achieved solely by using wearable products" | "Just wear it and watch the pounds melt" | "I wore it during my workouts and changed what I ate." |
| "promises of specific outcomes within a set timeframe" | "Lose 20 pounds in 30 days" | "Twelve weeks in, down 9 pounds. Most customers lose less than that." (only if your data supports it) |
The last row is the one brands misread. Meta's clickbait rule targets "sensational language with exaggerated or extreme claims, or promises of specific outcomes within a set timeframe." A promise is the problem, not a timeframe. The same standard asks dietary ads to show the time taken. The difference between the rejected line and the reviewable one is that the first promises the viewer a result and the second reports one person's result with the typical result beside it.
One more thing the policy page cannot tell you: Meta reviews the whole ad, including the landing page and the on-screen text. A clean script does not guarantee approval. It removes the patterns the written policy names, which is where most rejections start.
What about GLP-1 and prescription weight loss ads?
They are a different job with a gate in front of it. Meta routes prescription weight loss to its Drugs and Pharmaceuticals policy, which says "Meta requires online pharmacies and telehealth providers to be actively certified with LegitScript." Manufacturers can use LegitScript or Meta's internal review instead. Advertisers must "Only target people in eligible countries (United States, Canada or New Zealand)" and "Only target people 18 years or older."
If you are a telehealth brand without LegitScript certification, no script fixes that. Get certified first. If you are certified, everything else in this article still applies on top, and the FTC rules below apply with more force, because a drug result is the kind of claim regulators check.
What does the FTC require in a weight loss ad?
Two things that Meta's review will not catch for you. First, the FTC's Gut Check guide for media, published in January 2014 and still on the FTC site, lists seven weight loss claims that "experts say simply cannot be true." If your script contains one of them, the problem is not the wording.
| # | The claim, as the FTC words it |
|---|---|
| 1 | "causes weight loss of two pounds or more a week for a month or more without dieting or exercise" |
| 2 | "causes substantial weight loss no matter what or how much the consumer eats" |
| 3 | "causes permanent weight loss even after the consumer stops using product" |
| 4 | "blocks the absorption of fat or calories to enable consumers to lose substantial weight" |
| 5 | "safely enables consumers to lose more than three pounds per week for more than four weeks" |
| 6 | "causes substantial weight loss for all users" |
| 7 | "causes substantial weight loss by wearing a product on the body or rubbing it into the skin" |
Second, the typical-results rule. Under 16 CFR 255.2(b), an ad in which a consumer describes their experience "will likely be interpreted as representing that the endorser's experience is representative of what consumers will generally achieve." The FTC's own worked example is a weight loss ad: before and after pictures of a woman who lost 50 pounds in six months. Its reading is that the ad should disclose what users typically lose, in the example "women who use QRS Weight-Loss for six months typically lose 15 pounds." A line like "You should not expect to have similar results" does not fix the ad on its own.
In a script this becomes one line of on-screen text during the reveal, written from your own customer data. If you do not have that number yet, you are not ready to run a transformation ad. Run a UGC testimonial about taste, routine or convenience instead, and collect the data while it runs.
How do you script a weight loss video ad that passes review?
Write it backwards from the reveal, because the after shot decides how the before shot has to be filmed. A 30-second cut for Reels or the Facebook feed looks like this.
| Beat | Time | What the creator does | What the brief has to lock down |
|---|---|---|---|
| Hook | 0 to 3s | States their own goal or routine problem in their words | No question aimed at the viewer's body. The hook is about the creator, not the audience. |
| Before | 3 to 8s | Mid-shot, dated on screen | Camera position, window, time of day, clothing. No close-ups on a body area. |
| Routine | 8 to 18s | The product inside a real day: meals, workouts, check-in | Everything else they changed, so the ad never implies the product did it alone |
| After | 18 to 25s | Same framing as the before shot | No new filter, no new lighting, no retouching |
| Results line and ask | 25 to 30s | The typical result as on-screen text, then where to buy | Your generally expected result, from your data, with its timeframe |
Captions matter more here than in most categories, because a lot of Reels viewers watch with the sound off and the results line has to be readable without audio. For the full caption and scene format see the video ad script brief, and for the Meta-specific placements and ratios see UGC for Meta ads.
Before you write any of it, it is worth spending twenty minutes on what rival brands keep live. An ad that has run for months in your category has survived review and is probably profitable, and you can track the ads competing brands keep running rather than guessing at the angles from a swipe file.
How much does weight loss ad creative cost?
Less than one rejected launch, which is the number to compare against. The creative for a weight loss ad has three separate costs, and only one of them is the video.
| Cost | Who you pay | What drives it |
|---|---|---|
| The brief and script | A strategist, an agency, or a generator like ours | How many angles you want to test. Ours is $49 a month for unlimited briefs on Pro and $129 a month on Studio, and the first brief needs no account. |
| The creator's fee | The creator directly, or a platform that adds its own fee | Length, raw footage, and paid usage rights. Our UGC creator rates breakdown covers what US creators charge. |
| Time on camera | Nobody invoices it, but it is the big one | A real transformation takes weeks to film. A reshoot after a rejection costs the whole timeline again, not just a day. |
That third row is why the brief is worth getting right. A skincare reshoot costs a week. A weight loss reshoot can cost three months, because you cannot refilm a before shot once the creator has already changed. The cheapest insurance is a brief that spells out the framing, the timeline and the results line before day one.
Should a real customer or a hired creator film it?
A real customer if you can find one, and a creator only with honest framing. The FTC's Endorsement Guides say an ad that presents people as actual consumers should use actual consumers or disclose that they are not. A hired creator who films a genuine 12-week routine with your product is fine. A hired creator who reads a stranger's result as their own is not.
The practical answer for most supplement and program brands is both: a paid creator for the routine and product-in-use ads, where nobody is claiming a transformation, and a real customer with a documented timeline for the before and after. Our UGC for supplement brands and UGC for fitness brands pages cover recruiting for each.
Do weight loss ads on Facebook need a disclaimer?
They need the typical result, which is more than a disclaimer. A generic "results not typical" line does not satisfy the FTC example quoted above, and Meta's text asks dietary ads to show the time taken. The combination that covers both is one on-screen line: what most customers see, over what period. If the person in the ad was paid or given the product, that connection needs to be disclosed too.
Can I target women over 40 for a weight loss ad?
You can choose an age range of 18 or above, but the copy cannot call out the viewer's age or body. Meta's inferiority rule covers "terms, descriptions, or questions that are negative," so "Over 40 and can't lose the weight?" is exactly the shape it describes. Let the targeting do the selecting and let the creator talk about their own routine.
