Measuring servings along with MFP synced to TrainingPeaks has helped me settle down on the diet stuff. When you've got your calorie needs dialed in and know you're tracking things properly it takes a lot of the "oh ****" out of gaining a couple of pounds of water weight.
FWIW @ 160-163lbs I have my BMR set at ~2600/day and that seems to be working well. OK, if I never got out of bed it'd be more like 1700, but doing work takes calories, ride recovery takes calories, annoying my girlfriend takes calories...
I seem to gain a couple of pounds during the summer. My coach has told me it is blood plasma volume related due to heat. It goes away in the fall. I have also experimented with intentionally upping salt intake before longer races so that I retain more water and it seems to work pretty well.
Basically, worrying less but weighing like 1lb more than I otherwise would seems to result in better riding and day to day depth, which has lead to more consistency and a lot of extra power.
