The Stat Method Baseline
Your energy needs, body composition and daily targets from one short form — each computed by the same engine as its own calculator, so the numbers always match them.
- 01Enter the five core details. Energy and body results appear straight away.
- 02Add body fat or a waist measurement if you have them — each unlocks more.
- 03Choose a goal to see calorie and protein targets, then a target weight to see a timeline.
What the terms mean
- Baseline
- A measured starting point: where your energy needs, body composition and targets stand today, before you change anything.
- TDEE
- Total daily energy expenditure — the calories that hold your weight steady at your activity level.
- BMI
- Weight relative to height. A population screening measure; it cannot tell muscle from fat.
- FFMI
- Fat-free mass index — lean mass relative to height. Needs a body-fat estimate.
- Waist-to-height
- Waist divided by height. A better guide to cardiometabolic risk than BMI alone.
Adds lean mass and FFMI, and the lean-mass BMR equations.
Adds waist-to-height ratio.
Energy
Mifflin-St Jeor, the equation this site prefers for your inputs.
Body
Category labels come from population averages and can't tell muscle from fat — a muscular person often lands in a higher band despite low body fat. There is a further limitation worth knowing: the American Medical Association's 2023 position is that BMI correlates with fat mass across a population but loses predictive power when applied to one individual, that its cut-offs derive largely from earlier generations of non-Hispanic white populations, and that it should not be used as a sole measure. Treat this as a rough screening band, not a verdict on your health.

What these numbers
actually tell you.
Every number here matches its own calculator
Each section is computed by the same code as the standalone calculator it links to, so the Baseline can never disagree with them. Follow a section’s link to see the full working, compare the equations, or adjust details the Baseline leaves at their defaults.
These are estimates, not measurements
Every figure comes from equations fitted to populations, not from measuring you. Two people with identical inputs can differ by several hundred calories a day. Use these as a starting point, track your weight for three weeks, and let what actually happens overwrite them.
Why it sometimes declines to answer
If any calculator the Baseline draws on would decline your situation, the whole Baseline declines, with the same explanation that calculator gives. That is deliberate: one section should never show a number another section would refuse. The individual calculators remain available for narrower questions.
