True. But being told the wrong things to put in my mouth for weight loss sure made things a lot harder. Years back before low carb I did succeed in losing a substantial amount on the then recommended low fat semi-starvation type of diet through sheer force of will against constant hunger but quickly regained all plus interest the moment I ate a normal reasonable amount of food again. I still struggle to lose and avoid regaining even on low carb but it is a lot easier with more success and far less hunger. Exercise for me did nothing I could detect either way. I have always worked out quite a bit even while obese with no slimming effect. Also once had to take many weeks off due to injury during a time I was making no effort to lose or control my weight. I made no conscious effort whatsoever to deliberately change my energy/calorie intake and just ate based on appetite/hunger same as before and then later after recovering from the injury with return to fitness activities again. Weight remained absolutely stable throughout the entire experience. I did notice my body automatically adjust for the missing work outs by making me feel less hungry and genuinely not want as much food until I started burning more calories again and automatically went back to eating more. I was surprised by how my body handled things so precisely without any conscious effort on my part to maintain its desired homeostasis because before this experience I would have predicted I'd gain a bunch of weight while recovering, unable to move much. Body is pretty smart.
