I wouldn't read too much into trace vs. non-trace ketosis. This
usually refers to ketosis as measured by ketostix, i.e. ketones
in urine, which is simply the spill-over when ketone concentration
in blood gets to be too high. Too many factors affect this: hydration,
insulin feedback, dietary fat intake, etc. It would be premature to
attribute trace ketosis to enhanced gluconeogenesis. I could even
concoct an opposite scenario - since the body can make glucose out
fat (the glycerol part of it) it is plausible that more fat would be
burned to make glucose, discarding excess ketones (from all the extra
fatty acids) in urine. (I know this is not the case, simply illustrating
that we shouldn't jump to conclusions about this).
