I like CalorieKing. I bought the software (it was a one-time fee of around $40). It's a lot less clunky than some of the other options I looked at. I think it's terrific -- my only complaint is that I think the exercise estimates are off, so I do my own estimate and do fuzzy math to make their formulas end up with my estimates.

Has anyone been able to successfully use Beginner Triathlete's nutrition tracker? It's super-awkward. In general, I keep trying to use BT for workout logging and I just can't stick with it because even though the features appeal to me, using it is just so damn cludgy.
