So you want to stick to foods that give the most bang for the buck - or, more accurately, the highest amounts of nutrients per calorie.

Foods like white bread, refined sugar and non-diet soda provide lots of calories and almost no other nutrients. Simply switching to wholewheat bread will increase the amount of fiber and other nutrients you get, making it less likely that you'll get hungry or create a nutritional deficit.

It's like the difference between eating either a Mars bar or an apple and a banana. The calories are roughly the same, but if you eat an apple and a banana you'll be less hungry and will have satisfied more nutritional needs than you would have with a Mars bar.
