A ketogenic diet (or keto diet) is not likely to lower your cholesterol. In fact, it may actually raise your cholesterol. A keto diet is a high-fat, low-carbohydrate diet. About 90% of the calories you eat come from fat with this diet.
Some studies looked at obese people on a keto diet. The studies found that their total and LDL-cholesterol went down. But, most of the people lost a lot of weight in these studies. Other studies have found that losing weight can help lower cholesterol. So, it is unclear if their cholesterol went down due to the keto diet or the weight loss.
The keto diet may even raise your cholesterol, if you are not overweight. This can happen even if you lose weight on the keto diet.
The long-term effects of a keto diet are unclear. Talk to your doctor about other ways you can manage your cholesterol and your weight.
Keto with caution!
