Best Influencer Marketing Strategies for Weight Loss Programs

Influencer marketing has quickly become the secret sauce in the weight loss industry and with good reason. As the global weight loss market is set to balloon from a hefty $296.8 billion in 2024 to a jaw-dropping $572.4 billion by 2033, brands are getting creative with how they engage their audience. Gone are the days of one-off promotions or flashy ads. Instead, it's all about long-term partnerships, affiliate models, and turning influencers into dedicated brand ambassadors.

Case in point: Noom. The weight loss app has taken influencer marketing to the next level by offering up to $15 per signup and a generous 30-day cookie duration. This strategy not only motivates influencers to stay invested but also rewards them for sustained engagement. Forget the quick hit—Noom is building a community of real advocates, and it’s paying off. To learn more about how Noom successfully leveraged the creator economy, make sure to keep reading.

Also, we'll be spotlighting the best strategies that weight loss programs and brands can use to help grow their reach and expand their influence.


1. Turning Influencers Into Long-Term Brand Ambassadors

When it comes to weight loss brands, influencer marketing often revolves around the "shiny object syndrome" — finding the biggest names with the most followers. But here’s the twist: it’s not about buying influence; it’s about creating genuine brand advocates. Enter affiliate marketing — a tactic that takes influencer partnerships from a one-time promotion to a sustainable revenue-generating machine.

So, how does this work? Simple. Influencers become an extension of your sales force, and you reward them for their ongoing efforts in driving conversions. They don’t just talk about your product once and move on. They are motivated to keep sharing and engaging with their audience — long after their initial posts.

Let’s break down how Noom, the popular weight loss app, took this strategy to the next level and saw jaw-dropping results.

Instead of just paying influencers for a one-off post or product review, Noom turned their influencers into affiliate marketers. This means influencers didn’t just make money once from promoting Noom; they had the potential to continue earning commissions as long as new users signed up through their links. Talk about turning your influencers into long-term advocates!

Here’s how they did it:

  • Custom Affiliate Links: Every influencer got a unique referral link they could share with their followers. Each time someone signed up for Noom through their link, the influencer earned a commission.
  • Competitive Commissions: At $15 per new user signing up for a free trial (compared to $10 from competitors like WW International), Noom sweetened the deal for their affiliates. This made the program more enticing for influencers to promote.
  • Bonus Structures: Noom didn’t stop at flat commissions. They incentivized top-performing affiliates with higher commissions, bonuses, and even free accounts for personal use. This ensured that influencers had a real, authentic experience with Noom that they could genuinely share with their followers.
  • Cookie Tracking for Up to 30 Days: Most affiliate programs only track conversions for 7–14 days, but Noom extended this to 30 days. This longer window meant that influencers had more time to earn commissions from their audience's decisions, whether immediate or delayed.

But here’s the magic of this approach: it created a community. Noom encouraged influencers to share their progress with their followers over time, turning them into genuine brand advocates rather than just one-off promoters. They even created hashtags like #NoomNation and #NoomNerds, which helped foster a sense of belonging and encouraged non-paid followers to join in on the conversation.

Key Takeaway: Create a Mutually Beneficial Partnership

Take a page out of Noom’s playbook: turn your influencers into long-term partners by implementing an affiliate marketing program. Offer them competitive commissions, bonuses, and rewards for generating sales — and watch as they become more invested in your brand’s success. Influencer marketing doesn’t have to be a one-hit-wonder. With affiliate marketing, you can build lasting relationships that benefit both sides in the long run.

Are you ready to turn your influencers into your most dedicated sales team? It’s time to start thinking beyond product gifting and one-off posts.


2. Hosting Influencer Events and Retreats

Weight loss and wellness brands are constantly trying to break through the noise of influencer partnerships, where the “easy wins” are product seeding and influencer shout-outs. But here’s the deal: to truly connect with your audience and build long-term relationships, you need to create meaningful, educational experiences.

Enter: exclusive influencer events that bring real value and provide opportunities for influencers to deeply engage with your brand, while also arming them with educational content they can share with their followers.

Why does this work so well? Because it taps into something more than just surface-level promotion; it’s about creating an experience that not only showcases your brand but also empowers your influencers with knowledge, turning them into brand advocates who can speak authentically about your mission and products.

Take a look at MyFitnessPal's "Nourish: Mind and Body for Women" event, which used this strategy to stunning effect.

The genius of MyFitnessPal’s approach lies in the fact that it invested in creating an experience that was authentic, educational, and aligned with the brand’s evolution. By offering influencers exclusive, high-value content and opportunities to connect with the brand on a deeper level, they built long-term brand advocates who were genuinely motivated to share their weight loss knowledge and experiences with their followers.

It was about empowerment, transparency, and education — all key values that aligned with their target audience’s goals. This strategy not only fostered a stronger connection between the influencers and MyFitnessPal but also helped build a community of informed consumers who could make more conscious choices about their health and nutrition.

The results? 130 million people reached through the influencers' posts, showing just how effective the event was in turning a one-day experience into a massive digital campaign.

Key Takeaway: Create Immersive, Educational Experiences for Influencers

If you want to level up your influencer marketing game, consider creating an exclusive event that brings real educational value to your influencers. This goes beyond just offering them free product; give them an experience that aligns with your brand mission and provides them with the knowledge to talk authentically about your product.

When influencers feel empowered with credible, useful information, they become passionate advocates who will inspire their audience to take action — and amplify your message across platforms. So, don’t just throw an influencer meetup — throw an experience that’s impossible to forget.


3. Leveraging Micro-Influencers for Authentic Brand Engagement

When you think of influencer marketing, your mind might immediately jump to the big names—those mega-influencers with millions of followers who seem to have their faces plastered on every product. But what if I told you that the true magic lies in the smaller, more intimate influencer partnerships? Specifically, micro-influencers — those with smaller, but fiercely loyal followings — can deliver some of the most powerful, authentic brand engagement out there.

This strategy doesn’t just mean working with influencers who have a significant reach. It’s about leveraging influencers who are closer to their community and possess a deeper connection with their audience. For weight loss brands, this is the perfect approach to build trust, establish genuine conversations, and generate authentic buzz that goes beyond a single post.

So, how does it work? Instead of paying for just a one-time product shout-out, micro-influencers help you create a community around your brand through their more personal, real-time connections. They may not have millions of followers, but they have a niche, highly engaged group of individuals who trust their every recommendation.

Peloton, the at-home fitness giant, decided to turn its own fitness instructors into brand ambassadors, blending micro-influencer marketing with a sense of community. While Peloton instructors aren’t exactly “micro” in the traditional sense, they engage deeply with their followers — who see them as approachable, relatable, and, most importantly, credible.

These instructors, like Alex Toussaint (who is now a macro influencer), already had loyal followings of fitness enthusiasts, and Peloton cleverly harnessed their influence to amplify brand awareness.

Peloton’s decision to use micro-influencers (its own instructors) to promote their products allowed them to cut back on traditional marketing spend while still boosting engagement and brand awareness. With over 1.4 million members and a doubling of their revenue year-over-year, Peloton proved that micro-influencers can drive real growth when done correctly.

Key Takeaway: Build a Community, Not Just a Following

The real lesson here for weight loss brands? Micro-influencers are the secret sauce to fostering authentic connections with your target audience. Instead of looking at influencer marketing as a way to simply broadcast your message to the masses, focus on building a community of genuine advocates who can speak authentically about your brand.

So, think beyond the one-off sponsored post. Look for influencers who already resonate with your ideal customer base and offer them a platform to be part of your brand’s story. Whether it’s through digital events, sharing personal wellness stories, or creating community-based content, you’ll find that this approach not only drives conversions but also builds lasting loyalty with your customers.


4. Harnessing the Power of Creator Licensing to Supercharge Campaigns

In this sector, there’s a common misconception that influencer partnerships are all about flashy endorsements and paid shout-outs. But what if I told you that the true goldmine lies in creator media — a strategy where you collaborate with influencers in a way that not only promotes your product but also amplifies your best content in a meaningfully authentic way?

Creator licensing is an underutilized strategy that goes beyond simple influencer outreach and product gifting. It’s about licensing influencer-generated content to use across your own marketing channels, allowing you to amplify their authentic voice while tapping into their established audience. This tactic blends the authenticity of influencer endorsements with the power of your own paid media to drive targeted, measurable results.

Precision Nutrition leveraged creator media to achieve an impressive 4:1 return on ad spend (ROAS). The key? They used creator licensing to make influencer content work harder across multiple channels, and the results speak for themselves.

Precision Nutrition was initially skeptical about traditional influencer marketing. They had seen too many fitness influencers promoting products they didn’t actually use — a big no-no for a brand that prides itself on authenticity and deep connections with its audience. They didn’t want to just pay for a one-off post from someone who wasn’t truly invested in their mission.

Enter #paid — an influencer marketing platform that gave Precision Nutrition the ability to connect with influencers in a way that was aligned with their values. Rather than simply paying influencers to post about their services, they took a more integrated approach. Through creator media, they worked with influencers who had a genuine connection to fitness and health, ensuring their content was not only authentic but also shareable and impactful.

The results? Over 90,000 story views, a 350% increase in positive sentiment, and 1,300+ signups for Precision Nutrition, with a 4:1 ROAS. The ability to license creator content meant they could take their best assets — the ones that resonated most with audiences — and get more value from them across their paid channels.

This helped them reduce their CPA by 10%, ultimately making their marketing spend more efficient and effective.

The genius behind this strategy is clear: by amplifying influencer content through licensing, Precision Nutrition was able to reach new, highly engaged audiences without sacrificing authenticity. This tactic didn’t just rely on influencer posts alone — it took their best content, optimized it through ad tests, and used it as high-performing assets across multiple channels. The result? More engagement, more signups, and better return on investment.

The best part? This wasn’t a short-term boost. After the campaign's success, Precision Nutrition increased their spend with #paid by a whopping 326%, proving they found a strategy that worked and was scalable for long-term growth.

Key Takeaway: Amplify Influencer Content with Licensing

If you’re a weight loss brand looking to get more mileage out of your influencer partnerships, consider creator licensing. Instead of just letting influencers post on their channels, license their best content and amplify it across your own digital marketing campaigns. This will help you reach more people with authentic content, optimize your ads for better results, and ultimately reduce your cost per acquisition.

Don’t just let influencer content sit idly by — make it work harder for you!


5. Turning Customers into Brand Ambassadors

A slightly different approach than the first strategy on our list, creating long-term advocates—those who genuinely care about your brand and are eager to share it with others—has become the ultimate strategy for sustained growth. A great way to turn customers into brand advocates is by engaging them with interactive content and community-driven campaigns that make them feel like part of something bigger.

This strategy goes beyond just a promotional post or a freebie. It’s about empowering your customers to act as community leaders who educate and inspire their followers. By doing so, weight loss brands can create a movement that feels authentic and deeply connected to the brand, making the influencers feel personally invested.

Herbalife, known for its weightloss supplements and nutrition products, faced a dual challenge: launch a new skincare line and reinvent their established Healthy Breakfast Campaign. The solution? Herbalife didn’t just want to promote a product—they wanted to create a community of brand advocates through education and meaningful engagement.

Here’s how they did it:

  • Building a Community of Advocates: Herbalife leveraged its existing customer base by getting people involved in the “Healthy Breakfast Campaign.” Instead of focusing only on influencers with huge followings, they sought out everyday health-conscious individuals who could act as ambassadors. This grassroots approach helped make the campaign feel more personal, as it was rooted in real people advocating for the brand’s values.

  • Interactive and Educational Content: Herbalife didn’t stop at product promotion. They worked with influencers to create engaging, educational content about the importance of a healthy breakfast and the benefits of their new skincare range. Influencers didn’t just share their experience with Herbalife’s products; they educated their followers on why a nutritious breakfast is key to maintaining energy levels and boosting wellness. This kind of content wasn’t just about the product; it was about empowering influencers to become experts in the wellness field.

  • Contests and Gamification: To generate buzz and excitement, the campaign featured interactive contests that incentivized influencers’ followers to participate. For example, influencers encouraged their audience to share their own breakfast routines and tag Herbalife. This gamification element made the campaign feel more like a community event rather than a one-time promotion. It created an environment where people felt connected to both the brand and to one another.

  • Seeding Influencers with Relevant Content: TEAM LEWIS, Herbalife’s PR partner, ensured that the content was not only engaging but also relevant. Influencers were given the opportunity to educate their followers on how Herbalife’s products fit into a healthy lifestyle. They didn’t just talk about the benefits of the products; they integrated them into their daily routines, making the promotion feel natural and authentic.

The results were impressive:

  • The campaign garnered over 13 media coverage pieces on announcement day, providing valuable exposure.
  • 53 contest entries were received, demonstrating strong engagement and interest from both influencers and their followers.
  • Customer engagement rose by over 20% during the contest period, reflecting the success of the interactive content and gamification strategy.
  • The campaign not only helped launch the skincare range but also reinforced Herbalife’s overall brand message of weight loss, health, and wellness, with customers serving as authentic voices for the brand.

Herbalife didn’t just promote a product. They built a community of educated and engaged advocates who genuinely cared about their brand and its mission. The campaign didn’t just lead to product sampling—it created a sense of belonging that turned casual followers into long-term customers and brand supporters.

Key Takeaway: Create a Movement, Not Just a Campaign

For weight loss brands looking to build long-term success, it’s time to think beyond just influencer shout-outs. Instead of simply paying influencers to share a post, create a movement by empowering influencers to become advocates. Engage them with educational content, interactive experiences, and incentives that make them feel like they are a part of something bigger. When influencers are personally invested in your brand and its mission, they’ll turn into true advocates who spread the message authentically to their community.

So, next time you think about influencer marketing, don’t just ask, "How many followers do they have?" Instead, ask: "How can we turn this partnership into something meaningful that builds trust, loyalty, and a deeper connection with our brand?"


6. Using User-Generated Content (UGC) to Build Authentic Connections and Drive Conversions

Potential customers are constantly bombarded with polished advertisements and celebrity endorsements, but what really resonates is real people sharing real experiences. Enter User-Generated Content (UGC)—a strategy that involves leveraging content created by actual users, customers, or influencers to promote your brand. This approach taps into the power of social proof, showing that real people are seeing success with your product, which builds trust and credibility.

For weight loss brands, UGC is particularly effective because it demonstrates that the product works for everyday people—not just fitness models or influencers. By showing real testimonials, before-and-after stories, or daily progress updates, UGC becomes a powerful tool in building community and boosting conversions.

Jenny Craig used a UGC-driven campaign to generate authentic engagement and lower their cost per acquisition (CPA) significantly. The weight loss industry giant needed a way to stand out and capture the attention of potential customers. The solution? They turned to User-Generated Content (UGC) to create relatable, authentic, and engaging ads that would resonate with their target audience.

Here’s how the campaign unfolded:

  • Partnering with Real Consumers: Instead of relying on traditional influencers or stock footage, Jenny Craig worked with real users—people who were actively engaged in the Jenny Craig program. These users created their own video content, sharing their personal 28-day journey with the brand’s meal plan and fitness advice. This helped produce genuine, unscripted content that felt much more relatable and believable.

  • Optimized for Mobile and Social Media: The UGC videos were optimized for platforms like Facebook, where a large portion of Jenny Craig’s audience spends time. The content was designed specifically for Facebook News Feed and Stories, ensuring that it was both engaging and mobile-friendly. By focusing on mobile-optimized content, the campaign made it easy for users to watch, share, and engage with the ads directly on their phones.

  • High-Energy, Relatable Messaging: To match Jenny Craig’s brand voice, the UGC was edited to be dynamic and exciting, showcasing real people achieving real results. The videos included a blend of before-and-after transformations, fitness milestones, and emotional moments that highlighted both the struggle and triumph of the weight loss journey. This energy helped the brand stay fresh and engaging on social media, appealing to those looking for authenticity.

  • Social Native Creatives: By working with Social Native, Jenny Craig was able to leverage over 60 user-generated videos that captured a wide range of experiences. This gave the brand a diverse array of content, all created by consumers, to run in their Facebook ad campaigns.

The results? The campaign saw a 28% reduction in CPA compared to their previous benchmarks, showing that the authenticity of UGC had a direct impact on conversion rates and ad performance.

Key Takeaway: Harness the Power of UGC to Drive Authenticity and Engagement

For weight loss brands looking to increase conversion rates and build genuine connections, User-Generated Content (UGC) is a goldmine. Instead of relying solely on influencers or traditional advertisements, consider incorporating real customer stories and experiences into your campaigns. UGC is cost-effective, authentic, and most importantly, it builds trust with your audience by showing real people achieving real results.

Think about how you can encourage your customers to share their journeys with your brand. By showcasing their stories, you’ll create a more personal connection, which leads to greater engagement and ultimately, higher conversions.


Final Thoughts

Influencer marketing in the weight loss industry is shifting from short-term promotions to long-term, community-driven strategies. By embracing affiliate programs, immersive events, micro-influencers, creator licensing, brand advocates, and UGC, brands can build authentic, lasting relationships with both influencers and audiences—ultimately driving trust, engagement, and measurable results that scale over time.
