It's just an excuse fatties use to get out of having to take personal responsibility for their fatness. I bought a $4 container of mixed greens for salads and made some soup stock by boiling some chicken bones I had in my freezer, and I've literally been eating that all week because I'm sick and can't be bothered to make anything elaborate. It's not expensive, nor does it take a lot of effort, and it's still relatively nutritious (especially since I don't feel like eating anything at all.) Fats are just lazy.
