About Cals2Gains: AI Nutrition
Cals2Gains is the AI nutrition app built for people who actually train - not just for people who count calories. We give you what sports nutritionists give their clients: real science, macros that adapt to your training, and an AI that understands your plate without wrestling a database. SIX WAYS TO LOG A MEAL - AI camera: snap your plate, get a full ingredient breakdown - Barcode: scan any packaged product - Label OCR: point at the nutrition table, done - Search: USDA + Open Food Facts + Spanish BEDCA - Voice: "two eggs with toast and half an avocado" (Whisper) - Quick add and repeat your previous meal in one tap FRIDGE TO RECIPE AI (no one else does this) List what you have in your fridge. The AI generates a recipe that fits the macros you have left today. Save it, add it to your weekly plan, or log it as a meal on the spot. MACROS THAT ADAPT TO YOUR TRAINING Rest day, HIIT, long run, competition: your macros are not the same. We periodize calories and carbs with factors from 0.75x to 1.50x depending on the session. Protein stays constant: your muscle does not change because you trained harder today. BUILT-IN TRAINING PLANS Marathon 12 weeks, 10K 6 weeks, CrossFit 8 weeks. Every day the app adjusts your macros automatically based on the session. Or build your own plan from scratch. FIXES WHAT YOUR APPLE WATCH GETS WRONG Consumer wearables overestimate calories burned by 9 to 18%. We apply a scientific 0.9 coefficient so your deficit is real, not fiction. Cross-source aggregation of Apple Health + Garmin + Google Fit with no double counting. REAL SCIENCE Mifflin-St Jeor (82% accuracy) plus Katch-McArdle if you have body-fat percentage by bioimpedance. Protein in grams per kilo (ISSN Position Stand 2017), not as a percentage of calories. Margin of error 10 to 15%: we tell you upfront, we do not sell fake precision. SIX REAL GOAL MODES Lose fat, mini cut, recomp, maintenance, lean bulk, gain muscle. Each one with its own deficit or surplus factor and macro split, based on published literature (Helms 2014, Iraki 2019). WEEKLY AI COACH Every week it reviews your real progress and adjusts goals if needed. It tells you why calories went up or down: never blind decisions. WHAT TO EAT - AI MEAL SUGGESTIONS Five meals tailored to the macros you have left, your history, your allergies, and the time of day. WEEKLY PLAN + RECIPES + GROCERY LIST Full 7-day plan. Recipes with macros already calculated. Grocery list generated automatically from your plan. ANALYTICS AND PROTEIN DASHBOARD Charts for weight trend, adherence, workouts, protein intake. 7-day moving average so one bad weigh-in does not ruin your week. ACHIEVEMENTS AND STREAKS Unlockable achievements with celebratory animations. Progress you actually feel. INTERMITTENT FASTING AND WATER Fasting window tracker and water intake integrated into your day. PRIVATE PROGRESS PHOTOS Your photos stay in your account. Never used for marketing, never shared. BUILT IN SPAIN, NATIVE ENGLISH AND SPANISH No robot translations. Solo female founder, accessible at [email protected]. FREE TO START Full core functionality free. Optional Premium for unlimited AI, advanced Weekly Coach and custom plans.
