Yup, calorie counting is where it’s at. I lost something like… 60? Pounds in the year leading up to my wedding by just counting calories, as I was too busy between working full time and going to college full time to go to the gym consistently enough to rely on that. People underestimate caloric intake and overestimate the impact of physical activity in my experience. Not to say that physical activity is not important, more so that you can overeat calories much more quickly than you can burn them off.
