Al Roker Claps Back at the Dietician Who Criticized Him for Doing "Sad" Keto

Don't come for Al Roker's diet of choice. The Today Show personality has proven before that he can get feisty toward naysayers of the ketogenic diet, which he's been following since September. (Ask Roker about his favorite keto bread recipe!)

So, we were hardly surprised when the weatherman clapped back at a dietician who told him that his lifestyle choice was "sad." We're sure Jillian Michaels wasn't surprised either.

Here's what happened. On February 21, a dietician named Heidi Wells tweeted at Roker: "Sad to see another famous person falling for a fad diet." Roker's response? "Heidi, there are so many sadder things in the world. Have a great day." 

Indeed, things like global warming can't really compare with what Roker eats for breakfast in terms of sadness. But the dietician who tweeted at him isn't alone in having doubts about the popular high-fat, low-carb eating plan. Watch the video above to hear other experts weigh in on the diet — and other celebs clap right back.
