Example
- Weight
- 70 kg
- Age
- 40 yr
- Sex
- Male
Result: Schofield BMR 1676 kcal/day - male, 30 to 60 years: 11.472 x weight + 873.1.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Male
- under 3: 59.512W - 30.4; 3-10: 22.706W + 504.3; 10-18: 17.686W + 658.2; 18-30: 15.057W + 692.2; 30-60: 11.472W + 873.1; over 60: 11.711W + 587.7.
- Female
- under 3: 58.317W - 31.1; 3-10: 20.315W + 485.9; 10-18: 13.384W + 692.6; 18-30: 14.818W + 486.6; 30-60: 8.126W + 845.6; over 60: 9.082W + 658.5.
- Bands
- Closed at the bottom, open at the top: an age of exactly 30 uses the 30-to-60 equation. W is weight in kilograms; the result is kcal/day.
- Scope
- A BASAL rate. Activity, stress and injury factors are applied to it separately by the dietitian; this tile applies none.
