About macroBody

What is macroBody?

macroBody is an adaptive macro-tracking and nutrition-coaching app for iOS and Android. It sets personalized calorie and macronutrient targets, then measures your real metabolism from your own weigh-ins and food logs and recalculates those targets every week — so your plan stays tuned to your body, not to a one-time formula. It is built for people who want macro precision without the tedium of logging every gram.

In one line

A nutrition coach that learns your body from evidence, lets you log a whole day by feel, and tells you exactly what to eat — to the gram — to finish your day.

Who it's for

Made for people who track on purpose.

🎯

Cutting, maintaining or gaining

Anyone chasing a body-composition goal who wants macro targets, not just a single calorie number.

🏋️

Lifters & athletes

Hit a protein floor, pick a diet style, and cycle calories high/low across the training week.

😮‍💨

People who quit calorie counters

Tired of weighing every gram, or of never knowing what to eat to close the day. Lazy Add and Complete my day fix exactly that.

📈

Data-driven dieters

Want targets that adapt from real evidence — your trend weight and intake — instead of guesswork.

Why macroBody is different

Two things you won't find in any other tracker.

Plenty of apps count calories. Only macroBody lets you log a whole day by feel — and tells you exactly what to eat to finish it.

Lazy Add

Log a whole day by feel — in two taps.

Once you've counted calories for a while, you already know roughly what a normal day looks like. Lazy Add turns that instinct into a log. Drag one slider to say how today compared to a usual day — a bit less, usual, a bit more, anywhere from −40% to +40% — and macroBody scales your baseline into a full estimate: calories and protein, fat and carbs. Prefer numbers? Punch in approximate calories or grams and it fills the rest.

  1. Pick a baseline — your daily targets, or your average of recent days.
  2. Slide to how today felt vs. usual; watch the kcal and macros update live.
  3. Log it. It's tagged as an estimate, so your coach trusts it less by design.
Why it's smart

A fully-estimated day counts about 25% less in the metabolism math. So a fast, rough log keeps your streak alive and your day complete — without ever skewing the model that sets your targets.

Complete my day

Exactly what to eat — down to the gram.

The hardest question in any diet is "I've got 500 calories and 40 g of protein left — what do I actually eat?" macroBody answers it. It looks at what's left of your day and builds real, coherent plates from the foods you already eat — your saved recipes and the meals you've genuinely logged — then solves the exact grams of each ingredient to close the gap.

  1. AI groups your own foods into combinations that make sense on a plate.
  2. A local solver sets each ingredient's exact weight to land your numbers.
  3. Aim for your remaining macros or your remaining calories — your call.
Honest by design

It suggests only plausible plates (never whey with sausage), and if the day genuinely can't be finished cleanly it tells you instead of inventing nonsense. Unlocks after ~a week of logging, so it has your real food to work with.

The whole app

A coach, a food diary, and a metabolism model — together.

Every feature feeds the model that keeps your targets honest.

Adaptive TDEE — the core

macroBody starts from a standard formula, then back-calculates your real energy expenditure from how your smoothed trend weight responds to what you log, and blends the two by confidence as data accrues. Your daily calorie and macro budget is recalculated every week — the longer you use it, the more it's tuned to you.

AI photo logging

Snap any plate — a vision model identifies each food, estimates portions, and drops a fully-macro'd entry into your log.

Big food search + barcodes

A smart blend of USDA FoodData Central, Open Food Facts and FatSecret, re-ranked for relevance — plus barcode scanning and custom foods.

Micronutrients

Beyond calories: fiber, sugars, fat subtypes, omega-3/6 and minerals — per food and rolled up per day.

Recipes

Build a meal once from its ingredients — macros are summed — then log the whole thing or half of it like any food.

Weight-trend line

A smoothed trend cuts through water and salt noise, so you see the real direction and stop panicking over one-day blips.

Weekly check-in, with an optional game layer

Each week macroBody reviews your data, cleans out messy days, and updates your plan. You can earn XP and level up a character as you stay consistent — XP is computed server-side from your real history, so it can't be gamed — or hide the whole thing with one toggle.
