8 Best Affiliate Programs for Weight Loss (2026)

We reviewed publicly available affiliate terms — commission rates, cookie windows, and network — for weight-loss programs with verifiable, primary-source or consistently cross-referenced data. Eight programs met that bar. Two additional programs we checked were excluded: one operates as a multi-level marketing structure rather than a standard affiliate program, and one had commission figures that conflicted too widely across sources to confirm. Data last checked: August 14, 2026.

Noom

Noom pays $10 to $15 per trial signup through a 30-day cookie window on the Impact network, with a $100 minimum payout. It's a CPA model, not revenue share, so earnings per conversion stay flat regardless of what the customer eventually spends. Noom fits affiliates who can drive trial signups directly — comparison content, app-review posts, and "does Noom work" search traffic tend to convert well. Approval typically takes 24–72 hours.

HUM Nutrition

HUM Nutrition runs a 10% revenue-share commission with a 30-day cookie on ShareASale. Average order value sits around $57, which puts a typical commission near $5–6 per sale — moderate compared to flat-fee weight-loss programs, but HUM's product range (supplements, not a subscription program) makes it easier to combine with broader health and wellness content rather than dedicated weight-loss posts.

BistroMD

BistroMD's own affiliate page states a $20 flat commission per sale, with custom rates available depending on promotion type, a 30-day default cookie, and monthly payouts through Impact. As a meal-delivery program rather than an app or supplement, it suits content built around meal-plan comparisons and "best diet delivery services" searches. Applications are manually reviewed.

Trim Down Club

Trim Down Club offers 70% recurring commission on the full lifetime value of a referred member, including upsells, run through ClickBank. The company reports a refund rate under 7%, low for a digital subscription product in this niche. The recurring structure means income compounds with retained members rather than resetting each month — but ClickBank-hosted digital programs in this space draw more affiliate competition than physical-product offers.

Weight Watchers (WW)

WW pays a flat $10 per sale with a 14-day cookie window — one of the shorter windows in this list, so it favors affiliates with high-intent, ready-to-buy traffic over long research-phase content. Its brand recognition is a genuine advantage for conversion, though the program is seasonal: sales concentrate heavily around January.

ColonBroom

ColonBroom pays 30–40% commission with a 30-day cookie. It's positioned at the intersection of digestive health and weight loss, which broadens the content angles available (gut health, bloating, detox-adjacent search terms) beyond a narrow weight-loss framing.

Diet-to-Go

Diet-to-Go pays $40 per sale with a 45-day cookie through FlexOffers — one of the longer cookie windows here, useful for content that ranks for comparison or "best meal delivery for weight loss" queries where buyers take longer to decide. The company reports some partners earning over $1,000/month, though individual results vary by traffic volume and quality.

Nutrisystem

Nutrisystem's cookie duration is consistently reported at 20 days across FlexOffers listings, but commission figures conflict sharply across sources — from 2.4% up to 15% depending on where it's checked. We're listing it because the program itself is well-established and verifiable, but we can't confirm a single accurate commission rate at this time. Check current terms directly in FlexOffers before promoting.

FAQ

What is the highest-paying weight loss affiliate program? By flat commission, Diet-to-Go's $40 per sale and BistroMD's $20 flat rate are among the higher fixed payouts. By percentage, Trim Down Club's 70% recurring commission produces the highest lifetime value per referral if the customer stays subscribed, since it compounds over the membership rather than paying once.

Which weight loss affiliate programs pay recurring commissions? Trim Down Club is the clearest recurring option in this list, paying 70% on the full lifetime value of a member. Most other programs here — Noom, BistroMD, Weight Watchers, Diet-to-Go — pay a one-time commission per sale or trial signup rather than ongoing revenue share.

What cookie duration should I look for in a weight loss affiliate program? Windows in this list range from 14 days (Weight Watchers) to 45 days (Diet-to-Go). Shorter windows suit high-intent traffic close to a purchase decision; longer windows help if your content is more research-stage, since buyers often compare several options before returning to buy.

How do I get approved for weight loss affiliate programs? Most programs listed here review applications manually rather than approving automatically, particularly BistroMD and Noom. Sites with original, substantive content (comparison posts, ingredient or meal-plan breakdowns) get approved faster than thin sites built only around affiliate links, since weight-loss merchants face FTC scrutiny over unsubstantiated claims.

How We Built This List

We checked each program's own affiliate page where available (BistroMD) and cross-referenced network listings (Impact, ShareASale, ClickBank, FlexOffers) and third-party affiliate directories for commission rate, cookie duration, and payout model. We excluded one candidate operating as a multi-level marketing structure and one where commission data conflicted too widely to confirm. Nutrisystem is included with a flagged, unresolved commission range rather than a single guessed figure. We re-check all listed terms weekly; changes will be reflected here with an updated date.
