This, absolutely true for me. I am presently pretty physically active and it does zero for weight loss but lots for fun, companionship, fitness and strength. If anything, on days when I do a lot I get hungry and need to eat more that day or the next to compensate. Body's smart enough to automatically adjust and signal what it needs to survive and thrive. During a time I was inactive due to injury my appetite dropped, no weight gain, then went back up with resumption of activity, no weight loss. My diet is what makes weight loss happen.
