One hour of reasonably intensive cardio burns 500~600 kcal. If you have two such workouts a week it comes down to an increased energy use of 2600/(72500) = 7%. Or a large meal. Just looking at the numbers it seems spending some time at the gym is not going to do much for loosing weight. Or said differently: eating 7% less is easier.
Not sure about this. Herman Pontzer's work shows that the body adapts by burning fewer calories later, so your energy expenditure is the same. Burning 600 calories with exercise means burning 600 fewer later, like burning fewer calories during sleep or fidgeting less.
