Glycemic Index
A ranking of how fast carbohydrates raise blood sugar — useful shorthand for choosing steadier fuel.
The glycemic index scores carbohydrate foods by the blood-sugar rise they produce against pure glucose: white bread and sugary drinks spike high and fast; beans, intact grains, and most vegetables burn low and slow. Glycemic load refines it with portion size, since watermelon's high GI means little at normal servings.
Its practical value is pattern-level, not accounting-level: spiky carbs invite the crash-and-crave cycle that works against any deficit, while low-GI meals — generally meaning fiber, protein, and fat eaten alongside carbs — keep energy and hunger even. GLP-1 therapy flattens glucose curves pharmacologically; eating lower-GI simply rows in the same direction, and many patients find their taste drifts there unprompted.
This glossary entry is general information, not medical advice, and is written to be consistent with FDA prescribing information and primary trial publications as of its last review. Always consult a licensed healthcare provider for personal medical decisions.
