All your health metrics on one page
Enter your details once and DailyDesk works out every common health number together — your BMI and healthy weight range, your BMR (resting calories) and TDEE (maintenance calories), ready-made calorie goals for losing, maintaining or gaining weight, and your ideal weight from four classic formulas. Everything updates live and runs entirely in your browser — nothing is uploaded.
How the calculations work
- BMI is weight divided by height squared, with the standard healthy range of 18.5–24.9.
- BMR uses the Mifflin-St Jeor equation for resting calorie needs.
- TDEE multiplies BMR by an activity factor from 1.2 (sedentary) up to 1.9 (very active).
- Calorie goals add or subtract 250–1000 kcal from your TDEE, flagging any target below a safe minimum.
- Ideal weight shows the healthy BMI range plus the Devine, Robinson, Miller and Hamwi formulas.
Common questions
What is the difference between BMR and TDEE?
BMR is the calories your body burns at complete rest. TDEE is your BMR multiplied by an activity factor — the calories you actually burn in a day, and the number to eat around to maintain your weight.
How many calories should I eat to lose weight?
Eat below your TDEE. A deficit of about 500 calories a day is a common, sustainable target for losing roughly 0.5 kg (1 lb) per week. The goals table shows slow, standard and faster options and flags anything below a safe minimum.
What is my ideal weight?
There's no single answer. The calculator shows the healthy weight range for your height alongside four classic formulas (Devine, Robinson, Miller and Hamwi), which give slightly different single targets based on your height and sex.
Which BMR formula does this use?
The Mifflin-St Jeor equation — the modern standard for estimating resting calorie needs from your height, weight, age and sex.
Are these results medical advice?
No — they're general estimates from population formulas. Treat them as a starting point and talk to a doctor or dietitian before making big changes.
