"I've never eaten so much in my life," Morning Joe host Mika Brzezinski says of her stint as a guest judge on Top Chef this summer. "The food was all really great, and the experience was fun, but we were given massive portions! My takeaway was that this country really needs to focus on portion size." Brzezinski's next experience with food television is slightly more in tune with her own culinary preferences: On August 29, she hosts Cook Your Heart Out, a one-off cooking competition of heart-healthy recipes. "I try my best to be extremely disciplined about my diet," she explains. "I'm someone who has really struggled with food, but I've found a good place now. It's like alcoholism: Every day is a new day. It takes everything in my power, everything inside me to not fall off the wagon." Find out what she had to eat this week in our latest New York Diet.
