Keto may be the current “It” diet in Hollywood – with a parade of celebrities, including Halle Berry, Kim Kardashian, Vanessa Hudgens, Megan Fox, Adriana Lima and Katie Couric, said to be among the adherents and fans of the very-low-carb/high-fat regime – but not everyone is loving it.

Celebrity keto detractors include personal trainer Jillian Michaels, of “The Biggest Loser” fame, who has called the diet, which spurs a metabolic process called ketosis, “downright dangerous.”

“I’m sure you’ve heard the term ‘too much of a good thing’? Welcome to the keto diet,” she wrote on her blog last spring, adding that she knew that expressing reservations about the keto diet would “infuriate the keto community.”

“Do not go keto. Just work out, eat clean and don’t overeat. I promise you, balanced diet,” Michaels said in a follow-up interview with People. “It’s that simple.”

And in the last week or so, we’ve heard from two celebrities who, while they aren’t warning people off the diet, as Michaels has done, say that it hasn’t worked for them.

After being on the keto diet for seven weeks, “Today” co-host Savannah Guthrie hasn’t seen any results. "It's not even doing anything," Guthrie griped during an appearance on “Watch What Happens Live With Andy Cohen.” "I haven't lost anything! I haven't lost a thing.”

On the other hand, she noted, “I've eaten a lot of bacon and I like it."

So you know, there’s that.

Meanwhile, “Dancing With The Stars” pro Witney Carson also didn’t give the keto diet anything approaching a ringing endorsement in an interview with

“I’ve done keto before, and I felt really gross,” she said. “I did lose weight on it, but my skin broke out. I have eczema and my eczema was super, super bad.”

Carson said she also didn’t have much success with veganism and now just abides by a back-to-basics approach. “I’m just trying to stick to whole foods and trying to eat clean,” she told the online magazine.

Surely, Michaels would be pleased to hear it.
