Height

Weight to lose 13.438

Upper healthy weight 76.563

Current BMI 29.388

Formula: healthy max weight = 25 × height²

Step-by-step with your numbers:

1. Values used:

2. Current weight = 90

3. Height = 175

5. Weight to lose = 13.438

6. Upper healthy weight = 76.563

7. Height in metres = 175 / 100 = 1.75 m

8. Height squared = 1.75 x 1.75 = 3.063

9. Current BMI = Current weight / Height squared = 90 / 3.063 = 29.388

The math behind it

The healthy BMI ceiling is 25, so max healthy weight = 25 × height(m)². Weight to lose = current − that.

90 kg, 175 cm (BMI 29.4) → lose ~13.4 kg.

Is BMI everything?

No — muscle, frame and health markers matter too.
