Your Whoop says you're recovering great.
Your DEXA says you lost muscle.
GLP-1 medications work. But your wearable can't tell you what you're actually losing. P247 connects your data so you know before your next scan.

The weight is dropping. But what kind of weight?
Semaglutide, tirzepatide, and other GLP-1 medications are effective at weight loss. That part works. The problem is what comes with it.
Your wearable has no idea this is happening. HRV improves because you're eating less. Resting heart rate drops. Sleep scores go up. Everything looks green. But "recovering well" and "preserving muscle" are two completely different questions, and your Whoop, Garmin, or Oura can only answer the first one.
You find out the real answer 8 to 12 weeks later when you pay for another DEXA or InBody scan. By then, the damage is done.
You're already tracking everything. Nothing connects it.
Four data streams. Four apps. Zero synthesis.

"I'm thinking about getting generic sensors to upload data to the cloud and get an LLM to crunch it based on my own requirements."r/whoop, March 2026
"I track protein pretty carefully and I lift 3x a week. But I have no way to see whether those efforts are actually working to preserve lean mass between scans."r/glp1
"5 months on Mounjaro. Down 18kg. Whoop recovery has been the best it's ever been. Got a DEXA scan last week and found out about 4kg of that 18 was lean mass."r/Mounjaro
Stop guessing between scans.
P247 connects your wearable, nutrition, and body comp data into one morning brief. You'll know whether your current approach is preserving lean mass, not 12 weeks from now, but today.
