You forgot to mention the increase Human Growth Hormone during fasting, as an method the intelligent body used, to protect the important tissue "muscle, skin, organs, etc." from being burned for energy. If you deplete all your fat, then you are entering in a danger zone and even so, the body will begin to burn the damaged proteins first like tumors, cancer bodies, damaged cell even before touching the good ones. But overall, nice explanation and illustrations, thanks!

maybe it's beyond the scope of this video, but i would like to add 2 things - important is to know that glucagon has no effect whatsoever on muscles, but it stimulates an enzyme called hormone sensitive lipase (HSL) in adipose tissue which provides glycerol and fatty acids from triglycerols (and of course all the other things you mentioned) - proteolysis of muscle tissue is induced by cortisol
@salmjak
9 жыл бұрын
mali hali Read this on wikipedia but couldn't find a source: "Previously, glucagon was thought to activate HSL, however the removal of insulin's inhibitory effects ("cutting the brakes") is the source of activation" Could you please state your source on glucagon having a direct stimulating effect on HSL? EDIT: I think it's the same statement as "glucagon increases insulin", while this is true it's not the direct mechanism. Glucagon increases blood glucose which by itself will increase insulin secretion.
@magnushelmer91
9 жыл бұрын
salmjak Well, I think you are right that rather the absence of insulin activates HSL than the presence of glucagon. I wrote this 1 year ago (based on the available information my university provided me with) now that I have read the whole Robins - Basic Pathology it makes also a lot more sense. When you look at Non alcoholic fatty liver disease for example, you have an accumulation of fat in your liver. Why? Obese people tend to have insulin resistance --->HSL doesn't stay deactivated ---> HSL becomes activated and all these free fatty acids that have been released from the peripheral adipose tissue go to the liver and accumulate (very very general explanation).

Love this. I experimented the water fasting myself for 7 days and tested my blood glucose level 10 times per day. I need to warm everyone that the glucose level dropped to one third of normal level 3 days after last meal. It is not a smooth curve like you draw in this video. It has sharp collapse points. Driving at one third level of glucose is the same as drunk driving because it is very hard to focus, and generally a person becomes careless for all daily tasks. I did my experiment during a Christmas vacation time because everyone was having a jolly spirit, and my drunk behavior was less noticeable.

Hey! Very nice video. I love your work and am pleased to see it becoming better with time. I even borrowed your brain drawing for my profile, hope you don't mind! However I'm currently reviewing this topic at med school, and I was told proteinolysis can be, in fact, one of the first mechanisms to occur during absolute starvation. Your fat storages are actually saved for later it seems, I think this happens when you have an extra stress acting upon your body. This is especially important when considering parenteral nutrition in unawake obese patients in an intensive care unit. If you don't supply adequate daily nutrition, they will enter a catabolic state culminating in enough protein loss to impair respiratory muscle function. One would think that, having enough fat in their bodies, they would just burn it all up, but it seems our body hold a firm grasp on that. If you would like, I can search for a reference and link it here.

I maintain a balanced diet with exercise when im not on Keto. Honestly the best results I've ever seen!

HI, I am wondering something. I take caffein before a workout to give me some energy. I know that caffein has several effects on the brain (increase adrenaline, dopamine), and it increases the lipolysis. My question is when people get used to caffein the effect on the brain stimulation is not as strong as before but I wonder if the lipolysis effect will remain as high as at the beginning or if the lipolysis is related to the brain stimulation which would mean that if the brain effect decrease the lipolysis will decrease ? Thank you very much !

This is great. It would have been useful to mention that fatty acids can’t pass through the blood brain barrier and that’s why it needs ketones. And there’s something about red blood cells not being able to use fatty acids for energy either. (And sorry if I missed it if you mentioned this, but I think it’s important, because you did mention that the heart uses the fatty acids and then ketones, but you didn’t mention why the brain doesn’t, I think)

@bennguyen1313

At the 7min mark (and in the the khan video, 'How does the body adapt to starvation') it's mentioned that during the first day or so, most fatty acids (aceytl coa) enter the kreb cycle to produce ATP, but that prolonged fasting will cause NADH levels to rise and cause a switch to make ketone bodies from the excess aceytl-coa... but if FAAs enters the kreb cycle to produce ATP, isn't this glucogensis? Also if you consume exogenous ketones (ex. mct oil, red raspberries, etc), in an otherwise normal (non-carb restrictive) diet, what would be the brain's glucose vs ketone utilization? Are there any genetic component or polymorphisms that would make the liver less capable of producing endogenous ketones from excess acetyl-coa? Is it widely accepted that diseases of the brain (alzheimer's, parkinson's, huntington's, etc) are likely the result of insulin resistance of the brain? And therefore ketone therapy may be helpful?

6:18 "during starvation"? Ketogenesis already happens after 24 to 48 hours of fasting or at least very low carb consumption. It takes weeks before the body would begin entering starvation, as that relies on protein and fat stores getting depleted. You mean just 'fasting' where you talk of 'starvation', same with day 2 vs day 7 for example.
