It's very hard for people to sacrifice short-term enjoyment for a very vague and somewhat nebulous long-term benefit. Generally, as a race we take the short-term choice and discount long-term rewards - something that isn't totally irrational, if you think about it. IMHO it's easier to lose weight by changing things so you don't have to CHOOSE each day to do the right thing. If you move somewhere that you walk to work instead of driving, that's good for about 10-15 lbs, according to some studies, for example. As for the service idea, rather than making it something where I have to do the right thing each time, come up with something where I have to proactively choose to incur discomfort so I can deviate from my plan... I don't know, maybe make it so when I eat at a fast food joint and put it on my debit card, you double the bill and send the extra to a charity?
