I think that for someone out of condition and sedentary the idea of starting up some kind of sustainable fitness practice is quite a bit more intimidating than the idea getting on some kind of diet plan. It can be hard to picture oneself thinking of exercise as something that can be fun and rewarding beyond the health benefits, it is however possible for it to be a thing you love to do and look forward to. Diets fail 95% of the time. Calories in/calories out isn't wrong, obviously. From a physics perspective it is clearly less effort to sit still and not eat than it is to go do physical work of some sort. Once you introduce human psychology into the equation, however, everything changes.
