Guides and calculators
Everything we have written about tracking macros when you do not eat alone — plus three free calculators that need no signup.
Free calculators
All three run entirely in your browser. Nothing you type is sent anywhere.
TDEE calculator
How many calories each of you burns in a day — two columns, side by side, because two bodies never share one number.
Macro calculator
Turn a calorie target into protein, carbs and fat, with the split you actually want and sensible floors.
Protein calculator
How much protein per day for your weight and goal, with the evidence range rather than one invented number.
Tracking together
Macro tracking as a couple
The 800-calorie gap nobody mentions, and the specific failure that makes one partner quit in week three.
One dinner, two goals
One cutting, one gaining, one tray. What actually goes on each plate.
How the numbers work
Adaptive TDEE explained
Why a calculator's first guess is wrong for most people, and how measuring beats estimating.
Trend weight and why the scale jumps
Your weight moves several pounds a week for reasons that have nothing to do with fat.
How many calories to lose weight
The honest version, including why the 3,500-calorie rule overpromises.
Comparisons
