All my previous attempts at weight loss had been exercise based, but to be honest I was too damn lazy to stick at it. Eating less on the other hand is actually less effort (only being slightly facetious). But seriously - if you bring in your own lunch to work, you are totally in control of the calories you will eat that day (assuming you leave your wallet behind! Work vending machines are your pernicious enemy.) Willpower is of course the problem for all strategies, and breaking habits. If you get used to your chocolate bar at 3pm every day, it is hard to suddenly forgo it.
