Amy Robach wears many hats. By day she’s host of GMA3: What You Need to Know on ABC. By night she’s diving into true-crime stories on 20/20. With the latter show gearing up for a return this fall, Robach’s schedule is more jam-packed than ever. 

“I’m looking forward to continuing our incredible storytelling,” Robach tells me over the phone about 20/20 coming back. “The true crime, the mystery, just getting all of that insight from people. I think we’ve done such a good job of that. We’ve really cornered the market on it.” 

To prep herself for such an intense workload, Robach does many things. She’s an avid runner—when we spoke, she’d just completed the Berlin marathon—and follows a keto diet, which she started after battling breast cancer. (The 48-year-old is in remission.) On the diet, Robach tells me, she has more mental clarity, “boundless” energy, and a substantial decrease in her urge to snack mindlessly. 

“I was always searching for my next snack or my next meal when I was on a regular, standard American diet,” she says. “And I was very carbs-centric, actually. [Going keto] was a big adjustment, but once I did it, the biggest thing I got out of it was freedom. Freedom from searching for another snack. I was satiated.”

One way she stays satiated is cooking keto-friendly versions of her favorite recipes. Robach’s mom, Joanie, started a website, My Keto Home, where she shares all their delicious finds. One of Robach’s favorites is a Keto Cheesy Baked Angel Hair Casserole, a spin on her late grandmother’s signature meal.

“I love this dish because it reminds me of her,” she  says. “And my mom and I were saying, ‘Oh, man, if we could only figure out how to make that.’”
