MacroCodex

Take the guesswork out of figuring out how many calories to eat! By entering your caloric intake and body weight regularly, MacroCodex will tell you exactly how many calories your body burns each day, making it easy to figure out how much you need to eat.

It takes MacroCodex 3–4 weeks to determine your accurate maintenance calories (TDEE).

You'll start seeing results within 5 weeks!

How does it work? It's simple: when you eat more than your total calorie burn for the day (maintenance calories or TDEE) your weight goes up; if you eat less, your weight goes down. MacroCodex uses this relationship to determine your true maintenance calories very accurately using a state of the art adaptive TDEE algorithm.

Can it use data from smartwatches? No, smartwatches are not accurate at estimating calorie burn; you can look up studies on this. Using weight and calorie intake data is a more reliable method.

You can optionally import weight or total calorie and macro data using Health Connect from your smart scale app or any calorie-tracking app.

With MacroCodex, your weight loss or weight gain will never stall!

Does your weight loss or weight gain stop after a while on a diet? MacroCodex helps you spot dips in maintenance calories from metabolic adaptation, then auto-adjusts your calorie target and macros so your plan stays aligned with your real maintenance calories (TDEE).

Whether your goal is fat loss, muscle gain, lean bulk, cutting, or body recomposition, MacroCodex adapts as your body changes.
