About Glycemic Load Calculator

GL = (GI × carbs) / 100. More accurate than GI alone.

This diet calculator helps you assess, plan, or optimize a specific dietary pattern. Diet quality is one of the strongest modifiable risk factors for chronic disease, research consistently shows that what you eat matters more than precise calorie counting for long-term health outcomes.

Evidence base

This calculator is based on validated dietary assessment tools and evidence from large cohort studies (Nurses' Health Study, EPIC, PREDIMED) and randomized controlled trials. Each dietary pattern has a unique evidence base for specific health outcomes.

Practical application

Use the result to identify areas for dietary improvement. Focus on one or two changes at a time rather than overhauling your entire diet. Sustainable changes produce better long-term results than dramatic overhauls that last only a few weeks.
