Insulin Load Score
Insulin Load Score of Granola
Per 100g serving
Moderate Insulin Load
Granola triggers a moderate insulin response. It can fit well in most diets, but pairing it with fiber or healthy fats can help slow digestion and reduce the insulin spike.
How Each Macro Contributes to the Score

What Is the Insulin Load Score?
The Insulin Load Score (ILS) estimates how much insulin your body needs to produce in response to a food or meal. Unlike the Glycemic Index, which only considers carbohydrates and measures blood sugar response, the ILS accounts for all three macronutrients — carbs, protein, and fat — because each one contributes to insulin secretion.
Carbohydrates are the strongest driver of insulin release. When you eat carbs, your blood sugar rises and the pancreas releases insulin to shuttle glucose into cells. But protein also triggers insulin — amino acids like leucine and arginine directly stimulate beta cells in the pancreas. Fat has the smallest effect, but still contributes, particularly through incretins released during digestion.
The formula used here is: ILS = 0.56 × net carbs + 0.1 × protein + 0.03 × fat. Net carbs are total carbohydrates minus fiber, since fiber is not digested and does not raise blood sugar. The coefficients (0.56, 0.1, 0.03) reflect the relative insulin-stimulating potency of each macronutrient, derived from clinical research on postprandial insulin responses.
A score of 0–20 is considered Low — these foods cause minimal insulin release and are ideal for blood sugar management. A score of 21–50 is Moderate — normal for balanced meals. A score above 50 is High — typically seen in high-carb foods and large portions, where insulin demand is significant.
Understanding ILS helps you make smarter food choices — not by avoiding insulin entirely (it is a necessary hormone), but by managing how much insulin your body needs to produce at once. Spreading insulin load evenly across meals, pairing high-ILS foods with fiber and fat, and choosing lower-ILS alternatives when possible can all support better energy levels, reduced cravings, and improved metabolic health.
Frequently Asked Questions
What is the Insulin Load Score of Granola?
Granola has an Insulin Load Score of 33.9 per 100g, which is classified as Moderate. The score is derived from its macronutrient profile: 64g carbs (7g fiber), 13.7g protein, and 20g fat. The carb component contributes 31.9 to the score, protein contributes 1.4, and fat contributes 0.6.
How is the Insulin Load Score different from the Glycemic Index?
The Glycemic Index (GI) only measures how quickly a food raises blood sugar and only applies to carbohydrate-containing foods. The Insulin Load Score goes further by accounting for all three macronutrients — carbs, protein, and fat — since all three stimulate insulin release to varying degrees. This gives a more complete picture of a food's metabolic impact. A high-protein, low-carb food may have a low GI but still produce a meaningful insulin response, which the ILS captures.
How can I reduce the insulin impact of a meal containing Granola?
You can reduce the insulin impact by pairing Granola with fiber-rich vegetables (which slow carb absorption), healthy fats (like olive oil or avocado), and eating it as part of a balanced meal rather than on its own. Portion control also matters — halving the serving roughly halves the insulin load. Eating protein and vegetables before carbs in a meal has also been shown to reduce postprandial insulin spikes.
