Answer 1

“Stored energy” vs “metabolised” is completely different.

There are many many factors.

Simple answer is go put a 50kg ruck on and eat 5000 calories worth of highly processed food and go for a run. No PB’s here right.

Also obese people generally don’t move around as much so in that respect aren’t used to moving/exercising. With all the extra weight the burden on the cardiovascular system is ridiculous as well as stress on joints etc etc.

So someone who is “normal” weight might run comfortably at a heart rate of 150bpm.

But for an obese person it might be 200bpm for the same pace etc etc.

Also technically they will have more energy in a starvation scenario than a normal sized human.

This is the point of a calorie deficit right. Say your daily calories are 2000. And you decided to eat 1000 then you body is going to fill the void from “fat” stores.

Also muscle is metabolically expensive for your body to maintain so it will no doubt pillage most of muscle first then fat. Again it’s not a easy to explain without grossly oversimplification of everything.
