Warning: Low Carb Diet Could Be Hazardous to Your Heart

“Low-Carb” Diets Increase Heart Disease Risk

June 13, 2012

Low-carbohydrate diets can lead to weight gain and heightened risk of heart disease, according to a new study in Sweden. As part of an effort to reduce heart disease risk in the 1980s, more than 140,000 individuals were encouraged to decrease their fat intake. They did so, and their cholesterol levels fell—for a while. However, in the early 2000s, the low-carbohydrate diet fad led many of these individuals to forgo healthful carbohydrates and eat fattier foods instead. The results were higher cholesterol levels and overall increased heart disease risk.
