It's just common sense really. I know making your own lunch everyday is not glamorous but maybe try it for one week and see how you go. I tend just to make a bigger batch of food like curry and soup and take the leftovers for work, so it really doesn't cost you too much extra (and doesn't feel like a chore).
If you made your lunch everyday for a month...you could buy this*
