The Claim

Unhealthy low-carbohydrate and low-fat diets, characterized by high intake of animal products or refined carbohydrates, are each associated with a 12–14% higher risk of coronary heart disease compared to healthy versions of these dietary patterns, indicating that poor food quality negates the potential benefits of either dietary approach.

In plain English

Eating too many unhealthy carbs or too much meat and processed food—even if you're on a low-carb or low-fat diet—can raise your risk of heart disease by about 12–14% compared to eating healthier versions of those same diets.

See the scientific wording

Unhealthy low-carbohydrate and low-fat diets—those high in animal products or refined carbohydrates—are each associated with a 12–14% higher risk of coronary heart disease compared to their healthy counterparts, suggesting that poor food quality undermines the potential benefits of either dietary pattern.

What the research says

1 study
  1. Study: Effect of Low-Carbohydrate and Low-Fat Diets on Metabolomic Indices and Coronary Heart Disease in U.S. Individuals.

    The study found that eating low-carb or low-fat diets full of meat and junk food raises heart disease risk, but eating those same diets with plants and whole grains lowers risk — so it’s not the diet type that matters, but how healthy the foods are.
