The Claim
In overweight and obese adults, a weight loss of at least 5% of initial body weight is associated with a 13 mg/dL reduction in total cholesterol, while weight loss of less than 5% is associated with an 18 mg/dL increase in total cholesterol, and the degree of weight loss is a stronger predictor of cholesterol change than walnut consumption.
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 overweight and obese adults, losing at least 5% of body weight is linked to a drop in total cholesterol by 13 mg/dL, while losing less than 5% is linked to a rise in total cholesterol by 18 mg/dL, and the amount of weight lost matters more for cholesterol change than eating walnuts.
See the scientific wording
In overweight and obese adults, weight loss of at least 5% of initial body weight is associated with a 13 mg/dL reduction in total cholesterol, whereas those losing less than 5% experience a 18 mg/dL increase, indicating that the degree of weight loss is a stronger predictor of cholesterol improvement than walnut consumption alone.
When people eat walnuts, the healthy fats in them get absorbed and go to the liver, where they turn on genes that make more receptors to pull bad cholesterol out of the blood. This lowers the amount of cholesterol circulating in the body.
What the research says
1 studyBoth groups lost about the same amount of weight, but only the group that ate walnuts saw their bad cholesterol drop — meaning eating walnuts helped more than just losing weight alone.
