I've heard what you are saying, but I don't think it really holds as true as some might want us to believe.There still has to be times of hunger to get the body to tap into fat stores. It still really comes down to a calorie deficit at the end of the day. Bodybuilders in the 80's used frequent feedings of high carbs and lost fat and got in shape for a show. Yes they had their drugs too, but the body is still the body, the drugs just make it easier.
@KatariaGujjar2 жыл бұрын
@@doug2993 Calorie deficit model is outdated. It's the hormones. Insulin is a strong inhibitor of lipolysis. Even 1g of sugar entering the body will spike insulin for several hours, even though the 1g of sugar doesn't have enough energy for several hours of work.

We can utilize gluconeogenesis very easily to make the approximate 5 grams of glucose needed. The brain is very happy to also use ketones for energy, our ancestors went days without any carb intake and their brains did not suddenly stop working.

Does this proportion stay the same or proteolysis tapers off to save valuable muscles? If so, after how many hours?

It really depends how she was fasting. If she ate when she woke up and then ate before bed, she was probably really messing up her body's rhythm. There are some really important reasons why intermittent fasting has your eating window during the day either with only eating in the morning to early evening or only eating in the afternoon until evening, not at night and not when you first wake up.

I remember learning what you said. I'm not so convinced that it's just that simple step by step process. Obviously the leaner you get and the longer you've been fasting, the more likely for muscle catabolism. I've experienced that first hand, even with PED's to help spare.
@KatariaGujjar2 жыл бұрын
Muscles aren't spared initially. But HGH spiking after prolonged fasting conserves muscle and inhibits proteolysis. You will still lose muscle daily, if you are fasting everyday for more than a week and not getting sufficient dietary protein, but it is quite negligible + HGH will create more muscle than what is lost for OAA.

The liver is the most metabolically active organ of the body and with one of the highest energy expenditure. It uses the ATP itself. The ATP can exist in blood from other means (i.e. cell break down) but from the liver it's not transported to other organs. Each cell makes it's own.

@petrichor1002 жыл бұрын
yes it does. Unfortunately, I am saying this from experience. The los of muscle mass makes one look skinny fat even with the fat loss. Trying to rebuild the lost muscle mass as of now. I think fasting and cutting glucose is a deadly combo especially for those that are metabolically flexible to begin with and just looking for ways to stay healthy. What most people including myself think is "well, I feel great and energetic, so i must be fine." The reality is the drivers of this energy and "feeling good" are the stress hormones: adrenaline and cortisol. Hypothyroidism and adrenal fatigue are two possible outcomes if one does not interrupt this process early enough.

Just proves that carbohydrates are not needed at all by any human to survive! The human brain doesnt prefer glucose...in fact glucose will always be used first because glucose is toxic in excess amounts. 4g to 5g of glucose is required at any given point..which is all the human body requires. Ketones is a much more fuel efficient energy source as the end result is more ATP bang for your buck so to speak. So remember this. Carbs are not necessary..and your brain will always use excess glucose first as it needs to remove it from the circulation as quickly as possible. Ketones are not toxic and is the most fuel efficient source of fuel for the human body!!
