Cutting down on all fats in your diet—no matter what kind of carbs you eat—won’t make you any less likely to get heart disease over eight years.

Scientists tried lowering fat in the diets of thousands of women for over 8 years and found it didn’t make heart attacks any less common — even though they ate more veggies and grains. So, just eating less fat doesn’t seem to protect your heart.

The study looked at whether eating more or less saturated fat (like butter or meat) affects heart problems in people who already have heart disease — not whether cutting all fat helps prevent heart disease in healthy people. So it doesn’t directly test the claim.

The study says cutting fat alone doesn’t help your heart unless you replace it with healthy fats like fish or nuts—not sugar or white bread. So just eating less fat without worrying about what you eat instead doesn’t lower heart disease risk, which matches the claim.

This study looked at whether eating less fat helps prevent heart disease, and found that it doesn’t — even if people eat more carbs instead. That matches the claim exactly.
