Welcome! Trying something new can be a little intimidating and confusing. One of the best things about Kickstart style eating is that eating the meals makes me feel full.
The PCRM's four food groups page suggests that 1 medium piece of fruit • 1/2 cup cooked fruit • 4 ounces juice = 1 of the 3 (or more) fruit portions/day. For legumes, 1/2 cup cooked beans • 4 ounces tofu or tempeh • 8 ounces soymilk = 1 of the 2 (or more) daily servings. 1/2 cup rice or other grain • 1 ounce dry cereal • 1 slice bread = 1 of the 5 servings of whole grains each day. For vegetables, PCRM recommends eating 1 cup raw vegetables • 1/2 cup cooked vegetables 4 or more times per day. Hope this helps!
