The Claim

Among U.S. health professionals, adherence to a healthy low-carbohydrate diet characterized by plant-based fats and proteins and high-quality carbohydrates is associated with a 15% lower risk of coronary heart disease compared to adherence to an unhealthy low-carbohydrate diet rich in animal products and refined carbohydrates, indicating that diet quality is more important than macronutrient quantity in determining coronary heart disease risk.

In plain English

If you're a health professional in the U.S. and you eat a low-carb diet full of plants, nuts, and whole foods instead of meat and sugary carbs, you're less likely to get heart disease — it’s not just about cutting carbs, but what you replace them with.

  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 when people eat low-carb diets with more plants and whole foods, they have a lower risk of heart disease — but if they eat low-carb diets with lots of meat and junk food, their risk goes up. So what you eat matters more than just cutting carbs.
