When fat is used, it’s usually not turned into glucose, but rather into fatty acids, that can then be used by the mitochondria to power the cells. The signaling that triggers this is in fact done by a bunch of hormones that do indeed circulate in the blood to reach the cells specialized in storing fat, called adipocytes.
Depending of what triggers the transformation of fat into fatty acids( a process called lipolysis), those hormones could be insulin, epinephrin, growth hormone, etc.

What about ketosis? Are ketones a legit way to remove fat?
Lemminary@lemmy.world 2 months ago
Yes, ketone bodies are the result of the beta-oxydation of triglycerides. It’s the way the body breaks down fat into molecules that it can either burn or tranform into other molecules like sugar. The Atkins and ketogenic diets are legit, but it can be risky and you can harm your body (like your kidneys) without professional guidance.

I wonder if the bounce back is the body trying to find homeostasis… of sorts. I’ve gone hiking for a week and come back having lost 10 lbs. A month later I’ve gained it back. I know it’s your diet, but gaining it that fast can’t be normal.

You know, I’ve wondered that myself! It’s mind-blowing to me when people say they’re back at where they started. So I suspect it has to be at the genetic level to keep you at a certain weight. Here’s a talk by Dr. Giles Yeo (neuroendocrinologist) making the case for it.

Probably at least half of it is water weight, so it might be pretty close to the recommended pound per week

There are some working theories (with some amount, but not enough yet of good science) this has to do with your gut microbiome. Since these bacteria are a critical (and still largely unknown) link in not only our digestion, hormone response, nutrient absorption, and immune/inflammatory response.
In essence, a particular set of gut bacteria are good at breaking down certain types of food in certain quantities, and they’ll tell your body to keep giving that type food and quantity. So unless that’s changed with longer term dietary changes, you’ll return to your previous state because thats what your gut is telling you to eat keeping your original cycle.

Oh wow, interesting, and seems reasonable.
Any links to even mediocre science on this? Or anythung suggestive?
