I have almost no sense of smell and was a competitive athlete when I was younger so, "food is fuel" has been a pretty easy philosophy to follow. I forget about this sometimes. Mind projection fallacy ftw.
EDIT: Also, you can change your tastebuds if you just don't eat something for a while. I know that skim milk tasted a lot worse when I tried it again after switching to whole milk. Also, the easiest will power hack is to not need to use your will power. Don't leave snacks within your line of vision. Hide them at the very least. Better yet, don't buy them.
What causes your lack of sense of smell?
Information that surprises you is interesting as it exposes where you have been miscalibrated, and allows you to correct for that.
I suspect the users of LessWrong have fairly similar beliefs, so it is probable that information that has surprised you would surprise others here, so it would be useful for them if you shared them.
Example: In a discussion with a friend recently I realised I had massively miscalibrated on the percentage of the UK population who shared my beliefs on certain subjects, in general the population was far more conservative than I had expected.
In retrospect I was assuming my own personal experience was more representative than it was, even when attempting to correct for that.
