Show HN: I built an AI to answer health, diet, and fitness questions

Hey HN, I built HealthBuddy because I was overwhelmed by conflicting advice on how to lose weight and get healthy. Between influencers, TikToks, and Reddit threads, it felt like more noise than clarity.

So I created an AI-powered site where you can ask questions like:

“How do I actually lose fat sustainably?”

“What’s a beginner gym plan?”

“What’s a decent meal plan for bulking?”

“How do I stop late-night snacking?”

“How much sleep do I need if I’m training?”

It's built using GPT-4 with prompts tuned specifically for health, nutrition, fitness, and sleep. Answers are structured to be clear, science-backed, and actionable — no fluff or one-size-fits-all replies.

A few extra features:

Search bar for common health topics (e.g. bulking, meal timing, hydration)

Saved chat history (after first use)

Lightweight UI, mobile-friendly

No login required

Would love any feedback from you all, especially around UI, accuracy, and feature ideas. Try it here: https://healthpalai.netlify.app
