In individuals with Type 2 Diabetes, the 'obesity paradox' exists where the lowest mortality risk is observed in the BMI range of 25–35 kg/m2, but this is largely explained by higher cardiorespiratory fitness (CRF) rather than body weight itself.

Do not fear being overweight if you are fit. In Type 2 Diabetes, the lowest mortality risk is found in those with a BMI of 25-35, but this is because they tend to be more fit. Focus on building fitness. An obese person with high fitness has lower mortality risk than a normal-weight person with low fitness.
