Type 2 diabetes risk is never one thing. Body size, physical activity, and the overall quality of an eating pattern each move the odds — and, importantly, they interact: activity blunts the risk linked to higher adiposity, and a higher-quality pattern lowers risk somewhat on its own. Move the three sliders and watch the interaction field redraw. The numbers here are illustrative — they show directions and rough magnitudes from cohort studies and prevention trials, not a forecast for any one person.

Change vs reference—illustrative only
What the grid shows: each cell is the modeled relative risk for a body at that activity level (left→right) and body size (bottom→top), holding your current diet-pattern and family-history settings. The white ring is your current position; the dashed cross is the reference profile. Notice the shading flatten across the bottom rows as activity rises — that is the interaction.

This is a teaching model, not a diagnosis or medical advice. No single food or number causes or cures diabetes; risk reflects genetics, age, ancestry, sleep, medicines, environment, and access to care alongside the factors shown. Screening for prediabetes and diabetes is done with blood tests — fasting glucose, A1C, or an oral glucose tolerance test — through a clinician. Use this to build intuition about how factors combine, not to estimate your own risk.
Reference points named: the activity slider is anchored at 150 minutes/week of moderate-intensity aerobic activity, the amount cited for adults (18+) in the U.S. Physical Activity Guidelines. Body size here stands in for adiposity, usually captured in studies by BMI or waist circumference — both are population screening measures that misclassify individuals (they cannot separate muscle from fat, or say where fat sits), so this slider is a statistical proxy, not a verdict on a body.
