I'm going to have to strongly disagree with this. I lost 40 pounds using the calorie counting app. I minimized exercise to just two brisk daily walks so I wouldn't stimulate my appetite and stayed at 1200 calories along with intermittent fasting and no sugar and bam few months of that and I was human sized again. Anyone can do it if they're honest and resolved. I should also mention I have one of the usual "culprits" hormone wise that fats use as an excuse all the time so it probably made it harder than someone without that. That's why I have no respect for excuse making fats.
