For the past few years my willpower has been steadily increasing. If it lasts and I use it to accomplish something noteworthy, I might write a post about it.
Anyway, what should a rational preference utilitarian with infinite willpower do? Assume that there are no negative effects (unhappiness, stress) with using this willpower, and that they can control their emotions at will.
Clearly they should work a lot more, not spend time on recreation (movies, TV, games), stand instead of sitting, etc..
What else? Should they listen to music? Should they keep their muscles flexed 24/7 ? What should they learn, where would they have the most relative advantage? How much time would be worth spending on social interaction?
I can figure out these things on my own, but those questions are important and good ideas are very valuable.
The diet is the result of a 5-ish year development. The major changes were, first, elimination of animals, then animal products, then processed products and finally everything that wasn't fresh fruits and vegetables and some pb and tofu. I heard a couple reasonable talks in the past year making the case that fresh fruits and veggies are unequivocally the healthiest foods. I said fuck it, why not just eat all fruits and veggies then? This was ~3 months ago.
In every way that matters to me it has been an overwhelming success: it's cheap, it tastes good, it gives me ample energy, it seems to make me feel better physically and emotionally, I have lost weight, I think I appear more lean, and it's filling--it was a pleasant surprise to find that a small salad can create a satisfying fullness in my body.
*Added: One downside is frequent trips to the store.
The results here seemed unrealistic to me until I saw the earlier comment which revealed that 'pb' meant peanut butter. With that in mind the diet seems both sustainable and fairly healthy (assuming a lot of attention is paid to nutrient levels.) If not optimal then at least far better than most people's default eating habits.
