The American Idol alum hasn’t been shy about showing off her weight loss since she started shedding the pounds. She’s lost 37 pounds without exercise, all thanks to a book called The Plant Paradox.
“Everyone keeps asking me, so I’m like, ‘It’s not a secret!’ I just read a book,” Clarkson told ET last month. “It’s basically kind of rethinking everything, kind of how we eat processed foods, how we spray our foods, how we treat antibiotics like it’s Tic Tacs.”
“It’s a really great book that changed my life,” she added.
Clarkson is definitely proof The Plant Paradox can work, but how can everyone else implement the diet? ET’s Keltie Knight sat down with the book’s author, Dr. Steven Gundry, who revealed everything you need to know about the diet plan.
“I used to be 70 pounds bigger than I am now despite running 30 miles a week and going to the gym one hour a day,” Dr. Gundry reveals. “And so I eliminated foods that turned on our immune system, which are called lectins.”
