Which provider does what?
| Provider type | Examples | What they say they do on claims | Best when |
|---|---|---|---|
| Managed creator studio | Kiko | Briefs start from your approved claim list; every script and cut is checked against the FTC Endorsement Guides and platform rules; measurement without health-data leakage. Kiko has run programs for 70+ venture-backed startups since 2023, including 5 health and fitness apps. A seed-stage strength-training app got 14,500 trial starts in 8 weeks; 34% still training at day 30. With creators, paid ads and product growth run together as a full growth system, a Series B nutrition-coaching app grew subscribers from 40,000 to 155,000 in 9 months. | You also want paid amplification and retention measurement run by one team |
| Health and wellness influencer agency | inBeat | Briefs list approved claims, what to avoid and where each claim is sourced; says "your legal and compliance team has the final say" | You want HCP and patient-advocate creators as well as fitness creators |
| Fitness influencer agency | LMG Media | Says supplement and nutrition content is reviewed for unsubstantiated health claims before publication; runs app campaigns with codes and trials | Fitness, nutrition and supplement-adjacent apps |
| Your counsel or regulatory consultant | In-house or outside | Substantiation and final sign-off | Always required |

Which creator claims need what proof?
Health benefit claims need "competent and reliable scientific evidence", which the FTC says generally means randomized, controlled human trials (Health Products Compliance Guidance, III.B, December 2022). The guidance covers health apps and counts influencer marketing as advertising. "Risk" is Kiko's rating.
| Claim type | Example line | Primary rule | Proof to ask for | Risk |
|---|---|---|---|---|
| Feature or content | "200 guided workouts, no equipment" | FTC Act Section 5 | Current catalog | Low |
| Personal experience, no outcome | "I like the 10-minute sessions" | 16 CFR 255.1(a), (c) | Creator actually used the app | Low |
| General wellness outcome | "I sleep better since I started" | 255.2(b): may be read as typical | Typical-results evidence, or a clear statement of what users can expect | Medium |
| Specific weight or body result | "Down 20 pounds in 8 weeks" | 255.2(b); guidance III.C.1 (testimonials aren't substantiation) | Typical results under the same program | High |
| Condition or disease | "Fixed my insomnia" | Guidance III.A–B: implied claims need the same support | Clinical evidence matched to claim and population; check FDA device rules (FTC Mobile Health Apps tool) | Very high |
| "Clinically proven" | "It's backed by science" | Guidance III.B.1 | The studies, and whether they tested this app | High |
| Expert endorsement | "As a physical therapist, I recommend…" | 255.3 | Credential and what the expert reviewed | Medium–high |
| Before-and-after visuals | Side-by-side photos | 255.2(b); TikTok weight management ad policy | Same as a specific result; editing check | High |
The FTC's 2014 "gut check" guide lists seven weight-loss claims that should prompt a second look, such as major loss whatever a person eats. Treat those as never-say lines.
Does "results not typical" fix a creator testimonial?
No. Under 255.2(b), without proof a featured result is typical, the ad must clearly say what users can generally expect, and the FTC's own examples (255.2(e)(2)) find "results not typical" disclaimers insufficient.
| Version of a creator's 20-lb, 8-week story | Problem or fix |
|---|---|
| "I lost 20 lbs in 8 weeks! #ad" | Implies 20 lbs is typical |
| Same + "Results not typical" in small text | FTC examples say this doesn't cure it |
| Same + spoken and on-screen: "Most members who finished the 8-week plan lost about {X} lbs" | Works only if {X} comes from your own analysis of all users who followed the same plan, with the method on file for counsel |
| Reframed around the routine: "Here's my 8-week plan and how I kept going" | Lower risk; any number mentioned still needs the typical-results line |
What limits apply to health data and campaign measurement?
A fitness app that syncs with a wearable is "probably" a vendor of personal health records under the Health Breach Notification Rule (16 CFR Part 318, amended 2024), according to FTC guidance. Sharing identifiable health data with an ad platform without authorization counts as a breach.
| Rule point | Number or date | Source |
|---|---|---|
| Notice to individuals | Within 60 calendar days of discovery | Part 318 |
| FTC notice at the same time | Breaches affecting 500+ people | Part 318 |
| Media notice | 500+ residents of one state | Part 318 |
| Civil penalty | Up to $53,088 per violation (January 2025 figure) | FTC guidance |
| First enforcement under the rule | February 2023: proposed $1.5 million penalty and a ban on sharing health data for ads | FTC press release |
Practical consequence: creator promo codes and post-install "how did you hear about us?" questions keep attribution inside your own systems. Pixel or SDK events whose names reveal a goal ("started_weight_loss_plan") are the question to take to counsel. Since February 2025, Meta has stopped accounts it classifies as health and wellness from tracking or optimizing for lower-funnel conversion events (Triple Whale summary), so plan to optimize health-app ads to upper-funnel events.
What do the platforms allow?
| Platform | Rule |
|---|---|
| TikTok ads | US weight management policy (updated Sept 2026): weight-loss or muscle-gain claims limited to 18+; no "product alone" results, no "easy" or "guaranteed", no body shaming |
| TikTok branded content | Global policy (Nov 2023) prohibits "weight loss products or services" and "pharmaceuticals, healthcare and medicine products", with region-specific exceptions; the market-specific page (Nov 2025) has no US weight-loss, health or fitness entry. Kiko's rule: brief workout and nutrition apps as training and habit tools, never as weight loss, with no weight, body-result or condition claims |
| YouTube | "Includes paid promotion" required; healthcare and medicines restricted in Branded Content Policies |
| Meta | Run boosted creator posts as partnership ads, which carry an automatic "Paid partnership" label (ContentGrip). Health and wellness accounts can't track or optimize for lower-funnel conversion events (since February 2025) |
What does Kiko's claims checklist cover?
Kiko checks every script and ad against the FTC Endorsement Guides and platform branded-content rules. Health claims are signed off by the client's counsel before posting. The checklist for non-prescription health and fitness apps:
| Check | Pass rule |
|---|---|
| Approved claim list | Every claim in the script appears on the client's list, with its proof attached |
| Disclosure | Paid relationship spoken and on screen in the first seconds, not only in the caption |
| Weight or body result | Cut, or paired with the client's substantiated typical-results line |
| Condition or disease words | None ("fixes", "cures", "treats" and named conditions are struck) |
| Before-and-after visuals | Only with counsel sign-off and an editing check |
| Expert credentials | Stated accurately, with what the expert actually reviewed |
| Attribution | Codes and survey questions; no goal-revealing event names sent to ad platforms |
Example creators for a health or fitness app
Three fitness and nutrition creators from our wellness and fitness creator shortlist, each with an upload in the last 90 days. Kiko has no paid relationship with any of them.
| Creator | Platform | Audience | Why they fit a claims-reviewed program |
|---|---|---|---|
| Mind Pump TV (@MindPumpTV) | YouTube and podcast | 807K YouTube subscribers (vidIQ) | A near-daily lifting and fat-loss show whose listeners already act on coded host reads. Fits a workout app, with fat-loss talk kept off the approved claim list. |
| Abbey Sharp (@AbbeysKitchen) | YouTube | 717K subscribers (vidIQ) | Non-diet nutrition and myth-busting videos. Fits food-logging or meal-planning demos where claims stay tightly scoped to features. |
| Barbell Medicine (@BarbellMedicine) | YouTube and podcast | 75.2K YouTube subscribers (vidIQ) | A clinical, evidence-led framing of training and protein research. Fits a training or recovery app that wants a credible explainer rather than a results story. |
What should you ask any agency?
- Do your briefs list approved claims with the proof behind each one?
- Who reviews scripts and cuts, against which FTC standard, and how fast?
- How will you measure results without sending health data to ad platforms?
- Will you run creator videos as ads, and who re-checks claims before spend?
Frequently asked questions
Can a fitness creator share their own weight-loss results in a sponsored post?
Yes, but the FTC says a featured result may be read as typical. Without proof it is typical, the ad must clearly say what users can generally expect; a small "results not typical" line doesn't fix it.
Are testimonials enough proof for a health claim?
No. The FTC's Health Products Compliance Guidance says testimonials aren't substantiation; health benefit claims generally need randomized, controlled human trials.
Which agencies handle claims review for health and fitness app creators?
Managed creator studios such as Kiko and health-focused agencies such as inBeat and LMG Media describe claims review in their process. Your own counsel still gives final approval.
