Studies Say That The Keto Diet Might Actually Be Doing More Harm Than Good—Dietitians Weigh In

Why The Keto Diet May Cause More Harm Than Good

Mahesri says, "Following the keto diet has been linked to reduced muscle mass, increased LDL cholesterol, and increased total cholesterol (as noted in this study). This is likely due to the high saturated fat content and minimal fiber intake. The restrictive nature of the diet also leads to frequent rebound weight gain when re-introducing carbohydrates."

She emphasizes the nutrients that might be lacking in a keto diet and points out the low fiber content.

"Key nutrient deficiencies that might arise when following a keto diet include thiamin, folate, vitamin A, vitamin E, vitamin B6, calcium, magnesium, iron, and potassium (as stated in this study). Arguably most important, a keto diet is very low in fiber. Fiber is critical in blood sugar management, gut health, and reducing risk for cardiovascular disease," she notes.

The Bottom Line

However, there are positive aspects of the keto diet, and Mahesri recommends adopting those benefits while discarding the potentially harmful elements.

"For those seeking weight loss or general health benefits, I recommend taking the "good parts" of keto (high protein and moderate carbohydrate) and adjusting the "bad side" (using lean protein instead of saturated fats and adding back in fiber). When we adjust keto in this way, your cardiovascular risk lowers, and you are more likely to lose weight in a sustainable way," she reveals. Noted!
