According to
https://cdn.realfood.gov/Daily%20Serving%20Sizes.pdf, their recommendations do not meet their calories goal. Eg, for 2000 calories, you can eat 4 egg, 3 cup of milk, 4 slice of bread, 2 apple and 3 tbsp of oil per day.
Total calories will be 1,608 kcal/day.
It's a very depressing diet menu.
