> For unknown reason a lot of people still feel the need to eat even when their body is clearly in calory surplus.
Boredom, stress, unhappy life, happy life, laziness - it could be anything. You know what it couldn’t be? Exercise. I’m yet to see a person working out hard and eating at the same time.

No, but plenty of people have their hunger stimulated by exercise and eat too much after.
You simply can't fix being overweight or obese with exercise alone in the vast majority of people. Even if you don't believe in the constrained total energy model that a good chunk of metabolic research PhDs think is at least somewhat true and instead believe solely in the additive model, exercise stimulates hunger and it's far easier to eat 1000 calories than burn 1000 calories.
You have to do both and exercise doesn't automatically make the other easy.
