I've done something in the same vein, but not so detailed. Say I'm out for dinner and they offer desert. I have a sweet tooth, so I look at the menu. If it sounds absolutely great, I'll give in. But if it appears to be just OK, I say to myself "I'll save those calories for something better another day." Likewise, if potato chips are served with a meal -- if I ate them I'd get some marginal pleasure from it, but I can think of 20 ways to get more pleasure from the same number of calories. Mentally, I'm not denying myself pleasure; I'm banking it for future pleasure. The overall effect is I have fewer low-yield calories and fewer calories overall.
