Obesity, particularly intra-abdominal fat, is the most prominent modifiable risk factor for type 2 diabetes, with risk increasing exponentially with BMI.
Maintaining a healthy body weight is the single most effective way to prevent type 2 diabetes. Risk increases sharply as BMI rises, with obese individuals facing more than 10 times the risk of those with a normal BMI. Weight management is critical for prevention.
StrongSupportsVERY_HIGH confidence
Obesity and weight gain throughout life, particularly in the form of intra-abdominal fat, are regarded as the most prominent modifiable risk factors due to their combined high prevalence and magnitude of risk... Compared to persons with a BMI that is less than 22 kg/m2, persons who are overweight (BMI of 25-30 kg/m2) have 3 to 5 times the risk of diabetes, persons with a BMI between 30 and 35 kg/m2 have 5 to 10 times the risk, and persons with class II or class III obesity have more than 10 times the risk.
Why this rating
Based on multiple large-scale epidemiological studies and lifetime risk models.
