Brief Summary:
Very-low carbohydrate ketogenic diets can dramatically increase blood cholesterol levels, particularly in normal-weight people, for reasons that are not well understood. This study will enroll normal-weight adults, will identify "responders" who develop high cholesterol on a ketogenic diet, and will measure rates of production and removal of certain types of cholesterol-carrying particles called lipoproteins in responders. The results will clarify the mechanism by which a ketogenic diet can cause high cholesterol in certain susceptible people.
Detailed Description:
This study will evaluate the mechanism of ketogenic diet-induced hypercholesterolemia in susceptible normal-weight adults. The first stage of screening will identify eligible young adults who are normal-weight and at low cardiovascular risk. The second stage of screening will identify "responders" who demonstrate susceptibility to ketogenic diet-induced hypercholesterolemia by displaying an increase in LDL-cholesterol concentration after a 3-week screening ketogenic diet. Responders will be eligible to complete a randomized crossover clinical study at Washington University School of Medicine in St. Louis, MO. The randomized crossover study will involve isotope tracer studies of lipoprotein and cholesterol kinetics after two separate 4-week dietary interventions \[ketogenic diet and control diet\], conducted in random order with a 4-week washout period between interventions. All food will be provided to the participants as packed-out meals. Certain outcomes will use data from the screening process, comparing screen successes and screen failures to evaluate factors that could influence susceptibility to ketogenic diet-induced hypercholesterolemia.
