Health and fitness expert and trainer Jillian Michaels says “no” to the Keto Diet. In a recent interview with PeopleTV, she slammed the massively popular diet saying it was unnecessary for most people. While the low-carb, high-fat diet is one of the year’s trendiest diets with a throng of celebrity followers, it does have many critics including Michaels.

“Don’t do keto,” she says. “How much time do I have? And I’m not allowed to swear? Yes, keto is a diet fad. The reason that keto has been getting so much attention is because it helps significantly to manage your insulin levels. Very high insulin, very bad thing.”

“If you’re not eating a bunch of processed carbs and processed sugar and you’re not eating too much food in general, you won’t have insulin levels that are going through the roof. Calorie management and calorie restriction is less oxidative stress, so it’s far better for aging and being healthier,” she says.  So in other words, eat clean and healthy and exercise. 

While many experts agree with Michaels, the interest and popularity of the Keto Diet is unlikely to fade anytime soon.
