For type 2 diabetes prevention, reducing body weight (BMI) is more effective than improving cardiorespiratory fitness (CRF) alone.
To prevent type 2 diabetes, losing weight is more impactful than just getting fit. If you are overweight, focus on weight loss first, as it reduces diabetes risk more significantly than improving fitness alone. However, maintaining fitness is still beneficial and should be part of your overall strategy.

The HR of type 2 diabetes for overweight/obesity-fit category versus the normal weight–fit category (HR: 2.05...) was larger than that for the normal weight–unfit category versus the normal weight–fit category (HR: 1.26...; Pinteraction = 0.004).
Why this rating
Meta-analysis of 6 studies with large sample size (37,169 participants) showing significant interaction.
