Some mct's can be stored directly, some are elongated and then stored. Or acetyl-CoA from beta oxidation of medium chain fatty acids can be used to synthesize new fatty acids, just as acetyl-CoA produced from carbohydrate or amino acids can.

I think the lower initial morning ketones might be due to the decrease in metabolism during sleep--glucose and ketones are needed then mostly for the brain. Once you wake up, there's some competition. It might be like boiling a frog--as long as the increase in metabolism is relatively mild, from sleep to moderate activity, there's just a mild decrease in ketones early on. A big fatty meal will increase fat, so increase ketone production, as would a large increase in lipolysis from some sort of more strenuous activity. But a mild increase in energy expenditure just causes a mild, less stressed response. Also, after having a major meal at night, and then an inactive sleep, the liver might have been able to play catch-up, bringing liver glycogen up enough so that the increase in metabolic rate between sleep and the early morning could more easily be made up for by a slight increase in glucose production by the liver.
