So been researching this for a while and wondering if there are more than 1 pathway for fat loss and LBM gains. Meaning can the two happen simultaneously. Can anyone explain how the body prioritizes this from a biological standpoint? I thought the body statifises the fundamental engery needs to keep one alive and then what? Just trying to staisfy my need to understand.
By pathway do you mean physiologically? Then not really, fat oxidation is fat oxidation and muscle synthesis is muscle synthesis. Granted, there are usually a couple of different oxidative pathways depending on the enzymes involved but it’s still oxidation. The difference would usually be what the oxidiser and reducer are. Fat oxidation is how our body derives energy from fat. The only different pathways are really whether the fat is used to create glucose, and the glucose is the actual energy source; or whether the fat is used directly as an energy source by being transformed into ketones, but this can only happen when your body has absolutely no glucose to use (ie your glycogen stores are depleted). I think I got most of that right.
If by pathway you mean diet and training approach, sure. There are fuckloads. Except they all work the same way: they get your body to kickstart those physiological processes, which means inducing an energy deficit to kickstart fat oxidation; or causing sufficient damage to muscle that the body repairs it and adds more muscle to what was already there to cope with the increased stress.
