Colette explained to Redbook that Kim has protein in every single meal, coupled with high-fiber foods and healthy fats. “Sugar, sweets, cakes, crackers, white flour, white rice” are definite no-nos.

She also says Kim is eating about 1,800 calories as day, adding that “A low-calorie diet leaves you hungry all the time, and you need to not be hungry in order to be successful.”
