Topic FatMax (intensity at which you burn the most fat)
I can get pretty close. But I know my fat max.
how do you know yours? Most people have zero idea where their fatmax is and will way overestimate it. If you don’t measure it, you don’t know. It’s not at VT1.

I did a spiroergometry and interestingly i have a horizontal fat burning curve until VT1. At around VT1 fat burning starts to go down. So basically i have no specific fat burning max at intensities before AeT.
How can you test when you are burning the most fat? Is there a lab that can poke electrodes into your fat and detect it being burnt?
Also, does this adjust for temperature? I would bet running in cold weather beats any difference caused by pace. If you are at the south pole, you need 7000 calories a day of fat just to stay alive.
I was tested by INSCYD about 5 years ago. In order from slow to fast, the paces near FatMax that they gave me were recovery, FatMax, base, and what they called medio, which I guess was moderate.
The recovery, FatMax, and base paces were really slow. I wonder if the test was thrown off by a bout of food poisoning that I got just before the test. More likely I just sucked at fat burning as an age 60+ 400/800 guy.

You can measure how much fat is being used with indirect calorimetry. You run while your expired air is captured and analyzed based on that you can see how much fat and how much carb you are burning at a given intensity.
I would need to read up but not sure the temperature at which you run makes that much of a difference if you are running at the same pace. Open to someone showing evidence. Even then the difference is not likely going to be a lot.
The sad thing is that you don't expend nearly as much energy running as most people think. The 100 kcal/mile is a very solid estimate. If with that if you burned 100% fat (say you walked it) that would be all of 11 grams of fat.
As for this claim that you need 7000 kcals/d to stay alive in Antartica not sure where you are getting that number. That sounds like someone who is out hiking it or even dog sledding it, but someone just being there like a researcher is not going to need any more. Show me evidence of where that number comes from.
Lastly, just exercise and eat ok and don't worry about the type of fuel you burn while exercising.

At our lab in grad school we would ask runners who came in what their easy pace was. We would then look at the peak fat burning percentage (now this is different than maximal fat) and it was pretty much what their everyday, just going out for a run pace was.
Also, I think people are way overthinking this. If you enjoy running and are not training then run. Whatever difference there might be is going to be incredibly small and meaningless in the scheme of things. On a walk you might burn 10 g of fat in a mile. GRAMS!
If you are training then you need to run a variety of paces and distances and this would be worthless info IMHO.

The basic idea to train at (around) Fatmax is that the mitochondrias get maximum stimulated, from metabolic point of view.
