How the numbers are worked out
- BMR uses the revised Harris–Benedict equation (1984)
Multiplied by an activity factor (mostly sitting 1.2 / on your feet or light exercise 1.55 / physical work or regular training 1.725), it gives your estimated daily need.
- The target is 80% of that to lose weight and 115% to gain
The target shown follows the goal you choose.
- The salt target is under 7.5 g a day for men and 6.5 g for women
From the Dietary Reference Intakes for Japanese (2025). Restaurant food tends to be salty, so it is shown as a guide.
- Not medical advice
This is a rough guide from a general formula. If you have a medical condition or are being treated, talk to a doctor or registered dietitian.
