How to read the result
BMI was designed for statistics about groups of people, not for assessing one person. So treat it as a hint about whether to take a closer look, not as a diagnosis.
| BMI | What it means | What to do |
|---|---|---|
| below 18.5 | below the healthy range | check your diet and protein, talk to a doctor |
| 18.5–25 | healthy range | go by how you feel and what you eat |
| 25–30 | above the healthy range | look at portion sizes and activity |
| above 30 | well above the healthy range | consider discussing a plan with a doctor |
When BMI doesn’t work
- For athletes. Muscle is heavier than fat: a fit person can have a BMI over 25 with low body fat.
- In older age. Muscle mass declines over the years, and a “normal” BMI can hide that loss.
- For very tall or short people. Squaring height in the denominator inflates the value for tall people.
- During pregnancy and breastfeeding. The measure doesn’t apply.
What to look at instead of BMI
Waist circumference and how it changes say more about health than BMI: the guideline is up to 80 cm for women and up to 94 cm for men. Trends are even more useful: how your weight and waist change over a month, whether you get enough protein and fibre, whether you’re regularly active.
In the app, weight is a 30- and 90-day chart next to your calories and Score: you see the direction, not a single number. We don’t set goals like “minus 10 kg in a month” and don’t use judgemental language about bodies.
When to see a doctorThe service does not provide medical services. If your BMI is far outside the healthy range or your weight changes for no reason, see a doctor rather than changing your diet on your own.
