The Elevated Health Podcast
This episode traces the history and purpose of the glycemic index (GI), created by David Jenkins in 1981 to compare how foods affect blood glucose in controlled tests, and explains why glycemic load (GL) was introduced to account for portion size. It highlights the limits of GI testing—fasting subjects and isolated foods—and why real-world meals, meal composition, and preparation methods change glucose responses, using examples like watermelon and cooled-and-reheated rice. The show covers modern findings that individual glucose responses vary widely, how continuous glucose monitors (CGMs) reveal personalized patterns, and the many factors that influence blood sugar including sleep, stress, muscle mass, microbiome, and timing. Practical tips include pairing carbs with protein, fat, and fiber, choosing less-processed options, moving after meals, improving sleep, and using GI/GL as tools rather than moral judgments about food. Overall, the episode encourages using data wisely—focusing on how high and how long glucose rises and how well it recovers—rather than aiming for a perfectly flat glucose line, and emphasizes personalization over universal food rules.
