The Claim

In adult women, a diet with 60% of calories from low-glycemic-index carbohydrates increases daily caloric requirements by 11% ± 1% compared to a diet with 60% of calories from high-glycemic-index carbohydrates.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Quantitative

In plain English

Adult women who eat a diet where 60% of calories come from low-glycemic-index carbohydrates require 11% more daily calories than those eating a diet with 60% of calories from high-glycemic-index carbohydrates.

See the scientific wording

In adult women, a diet with 60% of calories from low-glycemic-index carbohydrates increases daily caloric requirements by 11% ± 1% compared to a diet with 60% of calories from high-glycemic-index carbohydrates, suggesting that glycemic index influences energy expenditure independently of macronutrient composition.

Why this might work

When people eat carbs that release sugar slowly, their bodies produce less insulin, which lets fat cells release more fatty acids into the blood. These fatty acids get burned for energy instead of sugar, and the process of burning fat uses more calories than burning sugar. The body also becomes less efficient at turning food into usable energy, so it burns extra calories just to maintain weight.

  1. Study: Low-Versus High-Glycemic Index Diets in Women: Effects on Caloric Requirement, Substrate Utilization and Insulin Sensitivity

    When women ate carbs that don’t spike blood sugar quickly, their bodies burned about 11% more calories each day just to stay at the same weight — meaning their bodies worked harder to use those carbs.
