Bild Health Launches App to Help People on GLP-1s Keep and Build Muscle While They Lose Weight

Founded by a 52-year-old Zepbound user, Bild Health is live on iOS and Android with watch apps, health sync and free calculators

CAMBRIDGE, Mass., Oct. 27, 2026 /PRNewswire/ -- Bild Health, the app that helps people on GLP-1 medications retain and build muscle as they lose weight, launched today on the App Store and Google Play. A meaningful share of the weight lost on GLP-1 drugs can come from lost muscle. Bild Health sets a daily protein target sized to each user's lean mass, makes it easier to hit with one-tap logging of protein, water, and workouts, and tracks fat and lean mass separately so users can see their muscle holding or growing as the fat comes off.

Founder Mike Putnam built Bild Health for himself first. After learning he was pre-diabetic in 2023, he started taking Ozempic and later switched to Zepbound, and in 2026 discovered how much of GLP-1 weight loss can be muscle.

"I built Bild Health because I needed it," said Mike Putnam, founder and CEO of Bild Health. "I'm 52. Three years ago I was overweight, low on energy, and my doctor told me I was pre-diabetic. A couple of years in, I switched to Zepbound and learned that you really have to worry about muscle loss. I measured mine, and I wasn't feeling as strong as I wanted to. So I built the tool I wished I'd had on day one, for people like me. It's working, and I'm excited to share it with the world."

The free Bild Health apps are available now on iOS and Android, each with a companion watch app for one-touch logging from the wrist. Bild Health syncs with Apple Health and Health Connect, pulling in weight and body composition from smart scales, and supports injectable and oral GLP-1s with dose reminders, injection-site rotation, and estimated medication levels.

Bild Health Pro, $59.99 per year with a 7-day free trial, adds an AI protein estimator that reads a meal from a photo or voice description, DEXA scan import including sync with BodySpec, and a PDF health report to bring to health providers.

Anyone on a GLP-1 can also use Bild Health's free GLP-1 protein calculator, plus body fat, water, and muscle loss calculators, at bildhealth.com.

Bild Health's approach is informed by scientific advisor and muscle-loss expert Roger A. Fielding, PhD, of Tufts University.

Bild Health is free on the App Store and Google Play. It provides education and tracking, not medical advice.
