MacroGuard

MacroGuard is a mobile app (with an optional web dashboard) for people following specific eating styles—keto, vegan, low-FODMAP, Mediterranean, gluten-free—who hate meticulous calorie tracking. Instead of logging every gram, users set their diet rules and “red lines” (e.g., max net carbs/day, avoid lactose, limit ultra-processed foods). The app uses barcode scan, quick photo capture, and restaurant menu lookup to give a simple compliance score and a clear “safe / risky / avoid” verdict with the exact reason. It also flags hidden ingredients and common diet-breaking additives, then suggests close substitutes from nearby stores or delivery apps. Weekly reports show which foods and situations cause most slip-ups, without shaming. This is a combination traditional + AI app: traditional for rules and databases, AI for label/menu parsing and photo-based food identification.
