This is actually brilliant in the sense that the key to resisting temptation might be to put as many potential obstacles in the way as possible.

If you can't resist purchasing junk food off the shelves, then put a limit on your credit card, or leave your credit card at home and only bring enough money to the store for essentials. And if that's not enough, then limit yourself to only shopping at health food stores where the options are less tempting, and so on.
