Does anyone have any idea why I start the day in moderate ketosis, but gradually it declines until at night I am completely negative (this is while on strict induction). Also after exercise in the morning I turn negative. I thought the opposite would happen. Does this matter? Am I still in ketosis? I thought it might be the water intake, but surely I would still be reading a trace? My weight is gradually declining (very slowly mind you) so I am not too concerned at the moment, but I'm not sure whether this is normal for some people.
