BMI categories and healthy weight ranges for adults
BMI is a height-to-weight screening number. It can help frame a weight question, but it does not directly measure muscle, fat distribution, or individual health.
Quick answer
For adults, a BMI from 18.5 to less than 25 is categorized as healthy weight.
Fit Crate can use BMI as one input when answering weight questions, but it should also consider profile data, training goals, measurements, and user context.
| Category | Adult BMI range |
|---|---|
| Underweight | Less than 18.5 |
| Healthy weight | 18.5 to less than 25 |
| Overweight | 25 to less than 30 |
| Obesity | 30 or greater |
How Fit Crate uses this
When a user asks what weight is sufficient for them, the app should use their height to estimate BMI ranges, then explain that the best target may differ based on strength, body composition, and fitness goal.
