LeanShield directly targets the muscle-loss risk of aggressive dieting and GLP-1 medications with a dedicated, RCT-informed score — a specific clinical angle most weight-loss trackers don't address.

What it is

A UK-based (Cambridge) AI weight-management app centered on "LeanShield™," a patent-pending real-time 1-100 score combining protein intake, deficit control, and resistance training to protect against the lean-mass loss associated with aggressive dieting or GLP-1 medications (the company notes up to 40% of weight lost on GLP-1s can be lean mass). It supports multi-modal food logging (voice, photo, text, barcode), personalized resistance-training workouts, weekly AI coaching with automatic target adjustments, and was designed with input from a University of Cambridge randomized controlled trial. Also licenses a "LeanShield API" to clinics, pharmacies, gyms, and insurers B2B. 7-day free trial ongoing subscription price not disclosed. 700,000+ users across its brands (including the related Turtle Method).
