I think as well there is some difficulty with variability between people that isn't clear or maybe doesn't matter at scale. The article linked study was across 43 nations with 4213 adults. Yet there may still be individuals who can argue differently. CICO (calories in vs calories out) must apply to us all, but the composition has an affect on what the body chooses to store vs how energised or hungry/satiated we feel. A bad diet could perhaps me we feel we have less enthusiasm for running or other activities. Age, lifestyle, and even cultural factors are massive in affecting metabolism (more the foremost) and of course what we consume (the latter two).
I run a fair amount (over 2000km/1200 miles in 2025) and find that once I start doing above ~70km/43 miles in a week whatever eating habits I have are indeed outcompeted by my running and weight loss is inevitable. Even so it does slow around a BMI of 23 for me for longer than I am able to be consistent with the running to observe further effects. Still my point is that my diet isn't anything to write home about and I anecdotally I feel that as far as weightloss is concerned I can very much outrun it.
It's well known though that as you build muscle, your rest calorie consumption increases, so probably if you build/maintain enough muscle, then you can just outrun your intake, since you consume more without doing anything to start with...

You have an amazing tool to speed up your work why wouldn't you use it?
