Keto Diet's impact on cholesterol varies by body weight, study finds

This study looked at how a four-week ketogenic diet changes cholesterol levels and heart health in healthy adults with a normal weight compared to those with obesity. Researchers wanted to see if the diet raises 'bad' cholesterol more in lean people and if it harms blood vessel function. Participants ate only provided meals and had regular blood tests and ultrasound scans. The results help understand how body weight influences the heart risks of a keto diet.
