Please don't promote this myth that exercise feeling easier due to different fitness levels means lower calorie burns.
It's so wrong it's the reverse of the truth - fitter people can burn more calories through higher intensity and longer duration.

My main sport of cycling is a good example as energy output (power) can be easily measured and the energy accurated assessed.

Example 1
200w is a fast pace and hard effort for me (720 net cals / hour). That's double the power and calories of many people who aren't very fit pushing at their fast and hard effort - irrespective of their weight. It's also about half of what a pro rider can produce and burn at same relative effort. The reason they are pro riders is actually because they have the capability to burn a lot more calories to produce more power than regular people.

Example 2
Fairly early on into taking up cycing I did a maximum sustainable power test. 612 cals/hour
Current max sustainable power. 810 cals/hour
Same feeling of maximal effort, I'm not more efficient I just have higher capabilities due to a better fitness level.

"Anaerobic high intensity training is hardly over rated if anything it is under rated, ask any professional athlete what they do if they want to lose weight."
Nonsense, you clearly have zero idea about how pro athletes train. Boxers doing long slow roadwork, cyclists doing long moderate intensity rides are far more typical.
What rate of burn would you have to achieve to match 4 hours of moderate effort riding do you think from a very short duration anaerobic effort?

BTW - I eat more food in my 60's than my 30's, 40's and am much slimmer.

Here is a 2016 study about the subject..

To summarise the more you exercise the more your body will adapt and at one point the total energy expenditure
plateaus. What it is saying is that you might be burning more calories with an exercise sadly it won't result in more weight loss, the body will simply compensate by lowering your TDEE. The more 'adapt' you become by getting stronger the more you need to exercise to get the same results. This study doesn't distinguish between the different types of exercises.
I may have been wrong about the cardio vs high intensity issue I admit they all seem to have the same limits in terms of how much weight one can actually lose by doing them. My apologies, this is why I love getting into debates, I learn.

That study is not saying what you think it's saying!
It's nothing to do with burning less calories through efficiency. It's saying some people's behaviours change if they feel fatigued, that's especially true if people attempt too much high intensity exercise beyond their recovery ability.

e.g. that study would support that after riding for 4hrs I felt pretty tired yesterday evening and didn't do much compared to a usual evening. But do you think sitting on the sofa for an evening in some way cancelled out a 1937+ cal burn?

And if you want to expand into strength training, the more weight you move the more calories you burn. It takes twice the energy to bench press 100kg rather than 50kg.

My TDEE was about 4,500 yesterday, yes that's unusual but over the course of many years I'm burning c. 600 cals a day on average. If that made me tired (it doesn't - it makes me feel energized) and reduced my NEAT a bit (it doesn't, since I got fitter I'm only more active) then there would be some compensation in spells of lower burn when not exercising.

None of that in any way makes your statement anything but completely wrong - "A five mile walk may have burned x cals before but as your body gets stronger the exercise gets more comfortable the body needs less energy hence will burn less calories".

We must be reading a different study.
Direct quote " Here we tested a Constrained total energy expenditure model, in which total energy expenditure increases with physical activity at low activity levels but plateaus at higher activity levels as the body adapts to maintain total energy expenditure within a narrow range. "..." For subjects in the upper range of physical activity, total energy expenditure plateaued"

As far as I can see how many calories we burn during an exercise is only part of the equation when it comes to weight loss. In that sense a 500 cal workout might result in the same TDEE as a 1000 cal workout at least according this study. So yes I was wrong, a five mile walk might result in the same calorie burn as a pro but your TDEEs will differ . A pro athlete is obviously 'very adapt' to exercise hence his
TDEE will most likely look substantially different to that of an amateur doing the same excercise.
By the same logic a fit person's TDEE will look different to an unfit person's by doing the same routine.
