Hey Product Hunt 👋 I built MuscleAI after going down a rabbit hole on why people lose muscle — not just fat — on GLP-1 meds like Ozempic and Mounjaro. Turns out appetite suppression means most people massively undereat protein, and the body burns muscle to make up the difference. Some research puts it as high as 40% of the weight lost being lean mass. The problem with existing trackers is they give everyone the same generic protein number. MuscleAI calculates yours from your lean body mass, your specific medication, your age, and your workouts — grounded in the Boer formula and ISSN/Morton et al. research. The feature I'm most proud of: snap a photo of your fridge and it builds an actual meal that hits your remaining protein for the day, skipping anything you're allergic to. There's also an AI coach that knows your context (ask it "what can I make for 40g?"), an injection day mode for nausea, and a weekly report card that grades your consistency. It's free to download. I'd genuinely love feedback — especially from anyone on a GLP-1 or building in health tech. What's missing? What would make this a daily-use app for you? Happy to answer anything about the calculations or the research behind them 🙏
