Kidney specialist warns of side effects from keto diet

Dr. Saad Al-Shehaib, professor and consultant of nephrology, has warned about potential health side effects caused by the keto diet.

In a post on his X account, Al-Shehaib noted that while the keto diet can be effective for short-term weight loss and improving blood sugar control, it should be approached with caution, especially when consuming excessive saturated fats or protein.

He explained that the diet involves reducing carbohydrate intake to around 20–50 grams per day, increasing reliance on fats, and consuming a moderate to high amount of protein. While this may lower triglycerides and raise HDL (good cholesterol), it can also increase LDL and total cholesterol in some individuals.
