The macro tracker that coaches you. Carbon Diet Coach is a nutrition coach and calorie tracker in one. Log your food, weigh in, and check in once a week. Carbon reviews your weight trend and what you logged, decides whether your targets should change, and explains every decision. Carbon pioneered adaptive macro coaching, and thousands of members use it to lose fat, build muscle, maintain, and reverse diet. HOW WEEKLY COACHING WORKS • Answer a few questions about your goal, body, and preferences • Get personalized calorie, protein, carb, and fat targets • Log your food and weigh in, or sync your weight from Apple Health • Check in weekly. Carbon looks at your multi-week weight trend and what you actually logged, then adjusts your macros or holds them steady • Read a clear check-in report, so you're never left wondering why Carbon did or didn't make a change • Pick your check-in day, or check in early when your schedule changes PROTEIN BUILT AROUND YOU Your protein target is based on your lean body mass, with an optimal range for your goal and diet style. Research links higher protein intake during fat loss to keeping more lean mass, so Carbon keeps protein front and center all week. FLEXIBLE CALORIE PLANNER The Calorie Planner works like a weekly calorie budget. Give yourself more calories for weekends, dinners out, and events, and fewer on quieter days, while your week stays on target. • Finished days reflect what you actually tracked, and the rest of your week rebalances around them • Hold protein keeps your protein target steady while daily calories shift • Adjust calories, protein, carbs, and fat for any upcoming day, or reset a day to your weekly defaults COACHING WITH GUARDRAILS When progress stalls, Carbon makes small changes instead of big cuts, keeps your rate of loss in check, and sets a calorie floor for you. If you reach it, Carbon recommends a switch to maintenance or a reverse diet. If your week wasn't fully tracked, Carbon won't react to incomplete data. SMART LOGGING Smart Logger: snap a photo of your meal or describe it, and Carbon matches each food to an entry in our verified food database. You review the matches, confirm your servings, and log the whole plate at once. Smart Suggestions: foods you log often are pre-filled in your diary. Tap to confirm or skip. Remaining Macros: see what's left for the day and preview how a food fits before you log it. Serving Amount Solver: enter the macros you have left and Carbon finds the serving that fits. Plus a barcode scanner, nutrition label scanner, quick add, copy meals, favorites, and custom foods and recipes. GOALS AND DIET STYLES Fat loss, muscle gain, weight maintenance, and reverse dieting. Choose Balanced, Low Carb, Low Fat, Keto, Plant-Based, or High Protein then fine-tune each macro within recommended ranges. PROGRESS YOU CAN SEE Charts for weight, body fat, lean body mass, calories, macros, and estimated metabolic rate, plus a check-in history showing every adjustment and why.
