I don't buy that eating McDonalds or ice cream or pop even regularly is inherently bad for you. People don't call a loaf of bread junk food, but is mostly just starches and sugars. A McDonalds burger may have a lot of fat and calories, but it still has beef in it which has lots of nutrients. Pop may be mostly just calories from sugar, but nobody is drinking pop as their only source of food and if your other foods are nutrient dense, I don't see much of a difference.
