Weightlifting for results is a full time commitment. I've seen what "counting macros" in your diet can do on top of constant routine and it's pretty significant. The trade off it that you'll lose most sense of pleasure from food, which personally I don't think is worthwhile. Especially when routine exercise does the job, just at a slightly slower pace
Or be a weirdo like me, its honestly almost a form of laziness, in that I pretty much eat chicken and rice for ~70% of meals simply because its cheap and easy to make. Use a few spices or whatever and its good to go.
That being said, I also don't count macros, but pretty much the easiest way is to just repetitively eat the same stuff over and over again.
