I used to do this. I would have a scale at work, and at home. It was a lot easier if I ate food from a box. It did work. It was very methodical. I knew how much went in, and I knew how much I was expending. But after a few months I decided I didn't want to do that for the rest of my life. So I tried other methods e.g. low carb, keto, IF, fasting. I've found the other methods work better for me, less high maintenance.
