Celebrities keep piling aboard the bandwagon for the high-fat, ultra-low-carb diet that sends the body into a state of ketosis and starts burning fat instead of carbohydrates for fuel. The latest well-known face to check it out is former Today show host Katie Couric. Just like many of the celebs and not-so-famous who have gone before her, Couric initially suffered some “keto flu” symptoms. But also like many before her, Couric felt the effects fade after a few days. Celebs and nutritionists alike strongly recommend that you consult your doctor before embarking on the keto diet.
“If you attempt it on your own, I suggest modifying the diet to allow more carbs—especially the ones you know you can’t live without,” says Sass. “In my experience, moderation is generally the key to shedding pounds for good, optimizing health, and living a balanced, enjoyable life,” says registered dietitian Cynthia Sass.
One common version of the plan sources 75 percent of daily calories from fat, 20 percent from protein, and just 5 percent from carbohydrates. Here are just a few of the celebrities who ditching carbs for a high-fat, moderate-protein keto diet.
The former Today show anchor is the latest celeb to try high-fat, low-carb keto diet. She posted on her Instagram that she’s loving it so far.
“So I’ve been doing the keto diet for a week now and I actually do feel better,” Couric said in late August, although she did mention the start was a bit rough. “The fourth or fifth day, I felt a little shaky and headachy, but I feel much better.” Those symptoms are common on the keto diet as your body adjusts to ketosis and burns fat instead of carbs for energy.
“I’m eating mostly protein and some cheese,” the 61-year-old said. “And I’m putting half-and-half in my iced coffee, and I gotta tell ya, it’s damn good.”
