Hey I really appreciate the comment on Caffeine. I have been talking my measurements in the morning before having coffee, assuming 24 hours without caffeine would be sufficient to eliminate the effect but perhaps I am a slow metabolizer too and should try going without coffee for a few days and seeing if that changes anything.

For body fat, are you doing Dexa scans or how do you measure? My bathroom scale spits out numbers but I doubt they are trustworthy.
