It's not that it doesn't work. It's not the primary tool for weight management. Gym is great for strength, muscle, cardio, and general fitness, but weight management is mostly about counting calories that go in. The calories that you burn are a function of your metabolism first and to a lesser extent the amount of exercise you do. The exercise side of things is < 500 kcal for most people per day.
The exercise is probably not that large an input compared to the baseline calorie consumption that added muscle has.
I guess I have pretty defined eating times and don't really think about food until I am hungry.
One thing that has changed a lot is that my lunches use to be either plain sandwich (like cheese meat and bread) or whatever I bought from a local restaurant.
I hated the sandwich days. I don't like mayo but the sandwiches always left me hungry and scavenging. Adding some hummus spread was a pretty huge change in the satisfaction that I got from that meal, and it doesn't leave me hungry.
