About This App
What it does
The McFacts Meal Planner helps you build a McDonald's meal that fits your nutrition goals. Enter a calorie target, an optional minimum protein, and an optional maximum carb ceiling — and the app finds the best 1–3 item combinations from the menu.
How scoring works
Each combo is scored up to 100% based on how closely it matches your targets:
Calories — bullseye scoring. Being 50 cal under scores better than being 200 cal under. Going over disqualifies the combo entirely.
Protein — hitting your minimum is the priority. Missing it applies a steep penalty. Slightly over is fine.
Carbs — acts as a hard ceiling. Within that ceiling, lower carbs score higher as a tiebreaker.
Data source
Nutrition data is based on publicly available McDonald's USA nutritional information. Values are per standard serving with no customisations. Actual nutritional content may vary. This app is intended as a planning guide only and is not a substitute for professional dietary advice.
