BMI Calculator
for Diabetics

A BMI of 25 or above (overweight) is associated with increased type 2 diabetes risk. For South Asian, East Asian and MENA populations, risk increases at a lower BMI — around 23. However, some people develop diabetes at normal BMI while others with high BMI never do — body fat distribution and genetics also matter.

Yes. Research — including the DiRECT trial — shows that significant weight loss (10–15% of body weight) can put type 2 diabetes into remission in many people. Nearly half of DiRECT participants achieved full remission through structured weight loss. Earlier remission attempts have higher success rates.

For European descent: men below 94 cm (37 in), women below 80 cm (31.5 in). For South Asian, East Asian and MENA descent: men below 90 cm, women below 80 cm. Waist circumference predicts abdominal fat, which is more directly linked to insulin resistance than total weight.

No. BMI does not measure body fat distribution. Waist circumference and waist-to-height ratio are better predictors of abdominal fat, which drives insulin resistance. This is why this tool combines BMI with waist-to-height ratio for a more complete picture.

Even a modest 5–7% weight loss can significantly improve blood sugar control, reduce insulin resistance and lower HbA1c. For most people this means losing 4–7 kg to see measurable improvement. This calculator shows your ideal weight range and how much you would need to lose to reach it.
