Tool
TDEEEstimate maintenance calories from body stats and activity.
Hub
Find maintenance, deficit, and surplus calorie targets.
If you only do one thing: run the TDEE Calculator, pick a goal (maintain, cut, or gain), and save your result link. Re-check it once a week with your actual scale trend and waist measurement.
BMR is your baseline burn at rest. TDEE is the baseline plus your daily movement, workouts, and general life. Most plans are built from TDEE, but BMR is still useful when you're sanity-checking a number that feels too high or too low.
A calm rule: if the plan feels unlivable, it's probably too aggressive. The goal is repeatable weekly decisions, not perfect math on day one.
| Goal | Typical starting adjustment | What to watch weekly |
|---|---|---|
| Maintain | 0% | Weight trend +/-0.25%/week |
| Fat loss | 10% to 20% | Waist + scale trend; hunger/sleep |
| Muscle gain | +5% to +12% | Strength trend + waist control |
Those ranges aren't moral rules. They're just starting points that minimize regret. You can always tighten or loosen after two weeks of real data.
When you're ready, use the deficit/surplus tools to generate a clean target you can share with yourself (or your coach) without retyping numbers.
This hub is built to keep you out of those loops. Use the calculators for the starting point, then let the weekly check-in steer the ship.
