A hypothesis? (could be meaningless in reality but it makes me think?)
I’m noticing it’s not so much the HIIT as it is the re-building of muscle that’s not embedded with fat, the more lean muscle I build the more carbohydrates I can eat as long as I increase the other two calories along with it.
I have friend who was in really good shape never exercised in her life and weighed like 98 pounds but she could not eat enough, she could eat and eat and eat and would lose weight instead of gaining no matter how much she ate, had a problem gaining weight, then three years later she was really fat, obesity pretty much described her situation.
Here muscles became fatty from the refined carbohydrates or was it from not eating an equal amount of calories; so she quit depleting glycogen storage while sleeping or at rest and going into ketosis naturally? Some will assume oh it’s just female hormones or this or that?
Calorie balance may effect the way the body reacts to storing or oxidizing fat or glucose.
When you eat calories equally in amount the body may have to go into ketosis by default when sleeping, when you increase the carbohydrate above fat and protein then you don’t go into ketosis naturally when sleeping by depleting muscle glycogen.
Per gram fat is 9 units of energy
Per gram protein is 4 units of energy
Per gram carbohydrates are 4 units of energy
Two grams of carbohydrates and protein would be equal (rounding off but does that 1 unit matter?) to 9 unit grams of fat.
It’s not about how your pancreas or liver use calories it is how your muscles use it?
