LeanShield™ for Insurers · PMI & payers

You're paying for the weight loss.
We protect the outcome.

GLP-1s are moving into private medical cover — and the cheapest claim is the one that never comes back. LeanShield™ keeps covered lives losing weight muscle-safely: members use consumer apps they'd choose anyway, and you see the cohort picture — safe-pace rates, risk mix, trend — built for outcomes-based contracts and long-term risk models. Never individual data.

👥 1,000,000+ users across our apps 🔬 Clinical RCT in design · University of Cambridge 🛡️ Patent-pending LeanShield™ score 🔒 Aggregate only · never premium pricing
The hidden liability

The scales improve.
The claims curve doesn't.

Weight-loss medication delivers the number on the scale. What it doesn't manage is what the weight is made of — and that's where the long-term claims live.

40%Up to 40% of the weight lost on GLP-1s can be lean mass — muscle, organ and connective tissue: the engine of mobility, recovery and healthy ageing.
7/10Around 7 in 10 people who start GLP-1s stop within a year — and regained weight comes back with a worse fat-to-muscle ratio. The second course costs more than the first.
49The average member joins LeanShield scoring 49 out of 100 — a level our data associates with 30–40% of weight loss coming from lean mass.

Lost muscle doesn't show up at renewal. It shows up years later — as frailty, falls, fractures and the slow claims that never close.

How it works

A benefit your members want.
A signal your actuaries can use.

01

Members get the apps

ParrotPal or Turtle Method — award-winning consumer apps on iPhone and Android, offered as a covered benefit. Voice-first logging, so engagement holds beyond week two. No IT integration required.

02

LeanShield protects the outcome

Every member gets a real-time 1–100 muscle-safety score, nudges on protein, pace and recovery — and workouts prescribed automatically to raise the score. Muscle-safe weight loss, by design.

03

You see the cohort

An aggregate dashboard across covered lives: safe-pace rates, risk-band mix, GLP-1 cohort trends. Built for outcomes-based contracts and long-term risk models — never individual member data.

The insurer view

Is the weight loss you're funding
safe? Now it's a number.

Cohort-level, continuously updated, board-ready — the outcome layer for the medication you already cover.

The line we don't cross

Cohorts, not customers.

Members own their accounts and their data. You see populations — never people. The LeanShield score is never shared at individual level and never used to price an individual's premium. That boundary is structural, audited and public — because a health benefit only works if members trust it. The full picture is on our Trust & security page.

Why LeanShield

The same engine clinics run.

Cambridge science

Built in scientific collaboration with Professor Nick Wareham, Director of the Cambridge Institute of Metabolic Science — with a randomised controlled trial in design, measured by hospital-grade body scans.

Already in clinical use

Heracles Health clinicians see every client's live muscle-safety score in their dashboards. HYVE, one of Wales' largest independent gyms, is rolling LeanShield out to 2,000+ members.

Engagement that holds

Over a million users across our award-winning apps, 4.7★ on the App Store — and a logging experience effortless enough that the data is still flowing at month six, when most wellness benefits have gone quiet.

+50%Average LeanShield score improvement across all members enrolled, in the first 30 days — movement your cohort dashboard sees as it happens.
Founding cohort

Founding insurer pilots
are being scoped now.

A pilot is one defined population, one agreed outcome measure, one quarterly aggregate report — designed with your clinical and pricing teams, with our DPIA pack ready for your DPO on day one.

Your members are already on the medication. The only question is whether the outcome is protected.
