I believe the best course of action is to plot your macros and try and stick with them. I also believe the more straight forward the formula you choose the easier it is to both monitor intake and comply with your diet. It took me quite a while to realise this until I read guys like Frank Zane, who survived on a basic: 250 PRO/50 CHO/50 FAT ratio, jacking the carbs up every third day as part of his cycling approach. Folks tend to over-complicate this these days when it's not really necessary.
Obviously there are a myriad of ratios to choose but the main thing is not to get bogged down in theory and start putting together a macros plan based on your activities and your goals. Next look at meal frequency. What works best for your lifestyle? Is it 6 meals? Is it 3 meals
plus 2 shakes? Then you nail down what you will eat at those times to hit the macros. Obviously you don't sweat things like green veg. Same with lean protein, e.g. tuna, fish, chicken breast, etc, as 100g = c.20g PRO. So it's easy to track. You may end up measuring stuff a few times to gauge portion size then you're good to go. For example, I love my PB but when I have it I now weigh it first because I found I was really over-estimating what I thought was a tablespoon worth.
