Ozempic, Wegovy, and Mounjaro are powerful. But four leading medical organisations confirmed what many patients already know: the support needed to truly succeed on GLP-1s is almost never provided. Fern fills that gap.

You're not imagining it
The prescription platform got you the medication. Nobody told you what to eat, how to move, what to expect emotionally, or what happens when you stop.
The nausea nobody warned you about
What you eat on a GLP-1 matters enormously for how you feel. Fern's meal protocols are built specifically for each dose stage.
The muscle you didn't know you were losing
Without resistance training, up to 40% of weight loss can be lean muscle, directly affecting your metabolism and long-term results.
The emotional complexity no one talks about
Food grief, identity shifts, body image anxiety. These are real and common. Fern names them and provides genuine support.
The fear of regaining when you stop
Without the right habits built during medication, most people regain significant weight. With them, the outcomes are dramatically different.
What's included
Built around your medication, dose stage, symptoms, and goals. Clinical protocols designed specifically for GLP-1 users, not generic wellness content.
Nourish
Personalised nutrition built for your dose stage, protecting muscle, hitting protein targets, managing symptoms.
Move
Resistance training to protect lean muscle during GLP-1 weight loss. Beginner-safe, home-friendly.
Feel
The dimension almost no GLP-1 platform addresses, the emotional complexity of rapid body change.

Adapts to your dose stage04
Build habits that last after the medication
When you're ready to stop, or when life makes that decision, Fern transitions into an explicit off-ramp programme. The habits you've built become the mechanism that sustains your results.
The off-ramp track · unique to Fern“Every protocol in Fern reflects what I do with my patients in clinical practice. The protein targets, the supplement protocols, the resistance training plans, and especially the emotional support. This is what I've seen people actually need.”

The biggest differentiator
Every other GLP-1 platform's support ends when the medication ends. Fern is built differently, from day one.
The off-ramp track
“We help you build the habits that stay after the medication doesn't.”
When you stop your GLP-1, planned or otherwise, Fern transitions into an explicit post-medication programme. Protein targets recalibrate upward. Resistance training becomes your primary metabolic tool. Sage focuses on sustaining the habits you've built over months. The difference between 0.8% weight change and 11% regain is the habits. Fern has been building them from day one.

The dose needed: with structured support
A 64-week Danish cohort study found patients with structured digital lifestyle support achieved equivalent weight loss outcomes at approximately half the standard GLP-1 dose. At $800–$1,100/month for Wegovy, the potential saving is significant.

Of patients discontinue within the first year
Real-world adherence data shows around half of GLP-1 patients stop within 12 months, primarily due to side effects, lack of results, or feeling unsupported. All three are addressable with structured guidance.

The maths
A 64-week study showed patients with structured support achieved equivalent results at half the standard dose. At current medication prices, that difference is substantial.

“Nobody told me about the muscle loss risk until Fern. I'm four months in and the protein targets alone have changed how I feel day to day.”
Nourish★★★★★
“The nausea in my first six weeks was making me want to quit. Fern's meal suggestions for the starting dose were the only thing that actually helped.”
Nourish★★★★★
“I stopped three months ago. Haven't gained the weight back. The off-ramp programme genuinely works. The habits really did stick.”
