After being a diabetic for 25+ years (currently diet/exercise controlled)
and a recent open-heart surgery patient, I have been following my diet VERY
strictly. My question is this: All the recommendations I see are for less
than 30% of calories from fat, a minimum is never mentioned. I know you do
required some fat though. I have been running low to mid teens fat
percentage with some days in single digits. Is this okay? Where do we draw
the line? Any input would be greatly appreciated.
