Calculators
Every one of these returns a number and then explains where it came from, how far it can be trusted, and what it cannot see. No email, no account.
Macro Calculator
Daily calories plus a protein, carb and fat split built from your bodyweight.
TDEE Calculator
How many calories you burn in a day, and what that means for your goal.
Protein Calculator
Your daily protein target in grams, and where the number comes from.
Calorie Deficit Calculator
The deficit for your target rate — and an honest timeline.
Body Fat Calculator
Body fat percentage from a tape measure, with its real margin of error.
Lean Body Mass Calculator
What your scale weight is actually made of.
1RM Calculator
Your estimated 1RM, the spread between formulas, and your working weights.
Ideal Weight Calculator
Four classic formulas, compared — and why they disagree with each other.
These give you a starting number. Holding to it for six months is the part that actually decides anything — that is what Dietly is for.
