This article is really saying you can’t out run a bad diet.
If you are fat, you eat too much.
Being active or not, you burn about the same calories.
Being active means taking the stairs, perhaps working out a bit.
Not running a marathon. Those calories have to be replaced.
I heard a talk from a guy that did 7 marathons in 7 states in 7 days.
His biggest problem was stuffing down enough calories.

Huhh.. Interesting… but that doesn't explain then how body builders and tri
athletes eat 5k and 10k daily diets and are fit AF…

More than 300 participants wore accelerometers similar to a Fitbit or other
fitness tracker 24 hours a day for an entire week while their daily energy
expenditure was measured with doubly labeled water. We found that daily
physical activity, tracked by the accelerometers, was only weakly related to
metabolism. On average, couch potatoes tended to spend about 200 fewer calories
each day than people who were moderately active: the kind of folks who get some
exercise during the week and make a point to take the stairs. But more
important, energy expenditure plateaued at higher activity levels: people with
the most intensely active daily lives burned the same number of calories each
day as those with moderately active lives. The same phenomenon keeping Hadza
energy expenditure in line with that of other populations was evident among
individuals in the study.

The new issue of scientific american shows that hunter gatherers expend the
same amount of calories per mass as me sitting at a computer.
“But a funny thing happened on the way to the isotope ratio mass spectrometer.
When the analyses came back from Baylor, the Hadza looked like everyone else.
Hadza men ate and burned about 2,600 calories a day, Hadza women about 1,900
calories a day—the same as adults in the U.S. or Europe. We looked at the data
every way imaginable, accounting for effects of body size, fat percentage, age
and sex. No difference. How was it possible? What were we missing? What else
were we getting wrong about human biology and evolution?”
