The Claim

Among overweight or obese individuals, high dietary glycemic load is associated with a 49% increased risk of coronary heart disease, while no significant association is observed in normal-weight individuals, indicating that body weight modifies the effect of glycemic load on coronary heart disease risk.

Supports is higher

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

In plain English

If you're overweight or obese, eating a lot of sugary or starchy foods might raise your chance of heart disease by almost half—but if you're a normal weight, those foods don’t seem to make a difference. Your weight changes how those foods affect your heart.

What the research says

1 study
  1. Study: Dietary Glycemic Index, Glycemic Load, and Risk of Coronary Heart Disease, Stroke, and Stroke Mortality: A Systematic Review with Meta-Analysis

    This study found that for people who are overweight or obese, eating lots of high-sugar carbs raises their risk of heart disease by almost half, but for people at a normal weight, it doesn’t seem to make much difference — so weight matters in how food affects the heart.
