BMR & TDEE Calculator

Your basal metabolic rate (BMR) is what you burn at rest. Total daily energy expenditure (TDEE) is BMR × activity. Get this number first; everything else (calories, macros, deficit/surplus) is built on it.

BMR & TDEE (Mifflin-St Jeor)

What to do with the number: maintain at TDEE; cut at TDEE − 500 kcal; bulk at TDEE + 300 kcal. Hit protein at 1.6–2.2 g/kg bodyweight first, then fat (≥0.6 g/kg), then fill the rest with carbs.

The Daily 7 — health on autopilot

A daily template. Hit 5 of 7 every day, all year. That's the program.

Sample daily template

TimeBlock
06:30Wake, hydrate (500ml), 10-min sun walk
07:00Protein-led breakfast
12:30Lunch — half plate veg, palm protein, fist carbs
16:0030–60 min training session
19:00Dinner — lighter
21:30Wind-down, screens off, dim lights
22:30Sleep
The rule: consistency > intensity. 5/7 days for 365 days beats 7/7 for 30 days.
