Hormonal Responce To Food Question

[Ghostman]

Hey guys, so if we slam down carbs the body releases insulin and stores whatever is in the bloodstream. Two questions actually. Once the body has stored everything and the small intestine and liver are empty will it continue to burn glucose as a primary fuel source? Second question. If we slam down 100g of fats the hormones needed to clear the FFA's from the bloodstream are completely different. So what would happen once the body clears 100g of fat from the bloodstream? Would it continue to keep the hormones necessary to break fat and begin to eat fat in stores assuming there is no insulin release? Or does it revert back to using glucose as a primary energy fuel source?

Thanks in advance to anyone!

I think this article will answer all the questions you asked.

That was a good read. My follow up question would be when does fat oxidation occur. Based on that article I get the impression its whenever there is no glucose in the bloodstream. I'm still a bit confused on the hormonal changes that would occur and why after someone consumes carbs versus fats.

Fat oxidation gets ramped up when glucose is in short supply. The body needs to get it's energy from some place and in the absence of glucose/carbs then stored fat and amino acids become the targets.

What specific hormonal changes are you talking about? Differences in them occur bc different metabolic pathways are required to process different macros. For example, anabolism is a response to a meal with protein but not a meal of only fats. Insulin is released from a carb and/or protein meal but not fats.

Thanks for the reply. So, protein and carbs will release insulin to transport glucose and amino acids to muscle tissues. Eating fat alone will cause no change in hormones and the FFA's that are floating through the bloodstream will be primary burned for fuel? Once the bloodstream is emptied the body will revert back to glucose and fat stores?
