Keto Cycle
Keto is known as the diet that works when nothing else does. That’s why so many people turn to Keto after years of yo-yo dieting. And at the start, it seems as simple as reducing carbs and increasing fats.
But after a while, eating the same thing gets so repetitive (there are only so many hamburgers with lettuce instead of a bun that you can eat).
Keto Cycle aims to solve that with its ketogenic diet app. When a customer signs up, they’ll receive personalized keto meal plans that refresh every 14 days. And because the product is digital (users prepare their own meals with their own ingredients at home), it’s relatively affordable, which makes the Keto Cycle lose weight affiliate program so delicious.

It’s easy to join the Keto Cycle affiliate program. Just fill out your application and wait to find out if you’ve been accepted.
Keto Cycle will ask you for some information about your business and your audience to make sure you’re the right fit. If you’re not in the health and nutrition space, you might not qualify for the program. Remember, appearing to be authentic is extremely important for all affiliate programs for weight loss.
Once you’re in, you’ll receive a unique referral link that you can use on your blog, in your email, and however you reach your audience.

Ace Fitness
What if you could make money from the people who are trying to make money? Confused? Don’t be. Let us explain.
Ace Fitness is a different kind of weight loss affiliate program. So far, the ones we covered are designed for those affiliates who want to promote weight loss solutions directly to those who want to lose weight.
This one’s different. When you become an Ace Fitness affiliate, you’ll be promoting exercise and fitness certification. So, instead of talking to consumers of weight loss, you’ll be talking to those who want to help people lose weight. These are the people who want to earn a certification to become a personal trainer, group fitness instructor, health coach, or medical exercise specialist.
How to Join
To join the Ace Fitness affiliate program, visit the program page and click the ‘Apply’ button. You’ll need to fill out an application first, which includes providing your website URL. Once approved, you’ll be asked to read through the T&C’s and sign on the dotted line (digitally speaking, of course).
When you’re done, sign in to your affiliate dashboard, grab your links, and start promoting Ace Fitness to your audience.
Commission: 7%
Cookie Duration: 90 days
Pros: No minimum payouts
Cons: The commission isn’t amazing

How to Earn More with Health Affiliate Marketing in 2025
Health and fitness is a lucrative niche. Affiliate marketers in this space earn an average of $7,194 per month! Here are some tried-and-true tips to help you cash in and keep climbing:
#1 Pick the Right Program
We’ve just covered the top five weight loss affiliate programs, but guess what? There are thousands more waiting for you to tap in. To set yourself up for success, it’s crucial to know how to pick the right one.
Here are some key factors to consider:
- High commissions and long cookie lifetimes. Big commissions ensure you’re fairly rewarded for your efforts, while long cookie durations give your audience plenty of time to claim your offers.
- Reputable brands. People trust established companies, so partnering with these brands makes it easier to build a steady income stream.
- Comprehensive affiliate support: A solid program provides access to promotional materials, tracking tools, and dedicated affiliate managers.
#2 Diversify Traffic Sources
Studies show that high-earning affiliate marketers ($10k+/month) diversify their traffic sources. To help you do the same, we’ve looked at strategies from other pros. Here’s a breakdown of the most effective sources:
SEO (yes, good old SEO)
As of writing this post, popular weight loss blogs are raking in some serious monthly organic traffic. Around 600k monthly visits, to be exact.
Can you imagine how many opportunities there are?
Create blog posts, reviews, and guides about weight loss programs, sprinkling in niche keywords like “best intermittent fasting program” or “healthy keto meal delivery.” These drive organic traffic with high buyer intent.
Email marketing
Are emails still effective? As an experienced pro, you’d say it depends on the niche, product, and audience.
But when it comes to weight loss programs? Email marketing works there REALLY well! Especially for offers with upsell funnels like Eat Stop Eat, which reports a 40% upsell conversion rate from email traffic.
You know what to do from there. Build an email list to share valuable information, promote programs, and drop in exclusive discount coupons. Your subscribers will love it!
Social Media Promotion
Health and fitness blogs hold the top spot for a reason. They deliver serious engagement and conversion.
Health and wellness sites convert at 1.9-4.2% (well above the 2.35% average). And optimizations tailored to this niche can push conversion rates 3-4x higher.
What does this mean for you? When you promote weight loss or fitness products, you’re not cold calling. You’re delivering value when interest (and intent) is at its peak.
Big players already leverage this. Mayo Clinic Diet has 138,743 Facebook likes and hosts a private group showcasing real health results.
#3 Craft Authentic and Value-Driven Content
Bland “how to lose weight” guides are a huge turn-off. People crave proof. Visual demonstration of how and why the products will work.
You can and must tap into that desire by including these content types in your strategy:
- Personal Stories: Share your own weight loss story or testimonials to build credibility. Sprinkle in visuals, tell about your struggles, and give insider tips.
- Educational Content: Create research-backed articles, videos, or infographics on topics like nutrition, exercise, and mindset.
- Product Reviews: Talk about weight loss products, tools, and programs, highlighting both pros and cons. Be the insider and honest judge whom your audience trusts.
#4 Use Effective Tools and Resources
2025 is the perfect year for affiliate marketers. With so many tools and services, you have everything you need to create, manage, and elevate your campaigns.
While every marketer has a few go-to tools up their sleeve, it’s always a good idea to check out what others are using.

FAQs
Does it cost anything to join an intermittent affiliate program?
If a weight loss affiliate program wants to charge you money up front to join, stay away. You’re there to feed customers to the affiliate program that you’re joining. You want to get paid for that, not pay them.
How much can I make from a weight loss affiliate program?
Commissions vary based on affiliate program. In some cases, you might get paid a flat rate for each conversion. In other cases, you might receive a percentage of each sale. Always read the terms and conditions of the affiliate program in question before getting started.
Are all affiliate programs for weight loss scientifically backed?
Not all affiliate programs are backed by doctors and nutritionists, but the good ones are. Always do your research before joining any health and wellness nutritional program. And when promoting any program, always encourage your readers to talk to a medical professional before starting.
Can I join more than one affiliate program?
Read the terms and conditions of the diet affiliate program you’re joining to confirm. It shouldn’t be a problem, but always remember that integrity is important. If you’re singing the praises of a Keto program one day and promoting a carb-heavy diet the next day, you might lose some credibility. Of course, competing diet products can be complementary. For example, and intermittent fasting product could pair well with a prepared meal service.
