PK, thanks for the post and sharing our insights regarding fasting. it's really fascinating.
I'm only speculating and thinking out-loud at this point. From the charts in your original post, there seems to be a relationship between the increase in ketones (B-OHB) and the release of fatty acids further into the fast. If you were to use a ketogenic diet to increase your B-OHB (ketone bodies) prior to fasting, do you think you could it could result in releasing free fatty acids within a 24 hour period as though you've been in a fast for 40 hours? Another way to look at the same questions. If my B-OHB levels were 1.0 in a fasted state and reached 1.8 at the end of 24 hours, wouldn't there be the potential to release peak fatty acids as though one has been in a fast for 40 hours?
I would also be interested to see if it's possible since cortisol levels would also be at it's lower levels while using a shorter fasting period while being in ketosis. What do you think?

This trilogy of threads has been absolutely fascinating to read! The idea of acceptably eating once a day holds many great promises, namely saving money on my food to feed our 3yo boy (who eats every hour!!)
I haven't bothered to calculate kCals with my food, I know I am currently not eating as much as I probably should. I am on Metermine (30 for 2 months, started 40s today) and I just don't really get hungry. Dinner is 3 veg and meat, say a cup worth of each? I have lost 14.3kg ((33lb) down from 101.5kg) in the last 2 months pretty much eating in a 16/8 style accidently, or with an omelette or plain bacon and eggs at societal breakfast. Would it be beneficial to learn to have CO on its own for more fat? Eating as much as I don't, I am eliminating about once a week, so would my body be utilising more of the food I am eating? And would CO help?
Ok so I have completed 8 days of 1 meal a day & I loved it completely! It felt great & everything was ..quite easy eventually.
But I chanced upon Mark's fasting articles (he's got about 8/9 of them just search out!) & he specifically mentions one shouldnt do the "same fasting regime" for too long because the body would get "used to it" & wind up slowing the metabolism etc etc.
My question is this - Is the 40-44 hour fast aimed at reversing this homeostatis? Or would it take a day/2days of normal feeding to reverse the body's functioning so that it speeds up the metabolism once again (hey there's lots of food, no need to slow down now folks!!) ?
Any thoughts on this would be very helpful! Happy fasting
Mix it up.
Lots of: urban hiking, cycling, sprinting
Lots of: fresh meat, seafood, eggs, organs, tubers, starchy fruits, low-energy plants, meat fat, dairy fat, oily fruits
Some: cured meat, dairy protein, sweet fruits, rice, peas, tree nuts, oily seeds
Minimal: soy, refined proteins, sugar, liquid carbohydrate, grains, beans, refined oils, peanuts
This study found that after 8 weeks of eating one meal a day (20-23 hour daily fasts) participants lost fat and gained lean mass despite the researchers efforts to have them eat the same number of calories as subjects eating three meals a day. This indicates (though doesn't necessarily mean) that the one meal a day crew had increased metabolisms. This sounds very reasonable to me. So after 8 weeks of intermittent fasting, the beneficial metabolism parameters were still present. Do you think the body would adapt if subjected to a longer intervention? Maybe!
