The Claim

The association between high dietary glycemic load and coronary heart disease is significantly stronger in overweight or obese individuals, who experience a 49% increased risk, compared to individuals with normal weight, who experience a 3% increased risk, indicating that body weight modifies the metabolic impact of high-glycemic diets.

What the research says

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.

In plain English

People who are overweight or obese get a much bigger risk of heart disease from eating lots of sugary, starchy foods than people who are a normal weight — like 49% more risk vs. just 3% more.

See the scientific wording

The association between high dietary glycemic load and coronary heart disease is significantly stronger in overweight or obese individuals (49% increased risk) than in those with normal weight (3% increased risk), suggesting body weight modifies the metabolic impact of high-glycemic diets.

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 eating lots of high-sugar carbs is more harmful to the heart for people who are overweight or obese than for people at a normal weight, which matches the claim that body weight makes high-glycemic diets riskier.
