I am not sure that it matters much, but intense exercise does reduce appetite.
Sedentary lives increase appetite. What is "sedentary"? Less than 7 hrs/week of exertion. Not activity - exertion.
Why might it not matter? Because, as I have asserted in the past, in our world of abundance and temptation appetite has little correlation with nutritional needs in adults. In the world of nutritional scarcity in which our distant ancestors lives, it certainly did. Today, we have recreational feeding. It is fun.
There are many reasons why daily exercise is useless for weight loss. Among them is the fact that a daily hour of "cardio" or calisthenics does not require additional nutrition from one's normal habit. People who lift heavy two or three days/week probably can use 60-90 gms of protein daily for muscle repair.
People in serious training for physical competition are another category. A 2-3 -hour daily workout has different nutritional needs. Two hours daily of physical training sounds wonderful to me at this point in life. One hour in the gym and one hour of sports practice. Only college kids and the retired have that luxury.
With nutrition, best thing to do is to set goals for your desired fitness and functionality levels and to pursue those in a disciplined way. Same as everything else in life.
