I have been working some on looking more closely at the protein/carb/fat content of what I eat. I've been using an app called Lose It! I think there are dozens of apps out there that will do this kind of task.

An app certainly does make it easier, though. It takes a bit of work at the beginning, but then it gets easier because at least 50% of what I eat is routine (breakfast smoothie, etc.)

I am also doing this for my depression and anxiety, as I have found that making sure I have a nutritious breakfast and making sure that the carb/protein ratio in my meals isn't too high have a pretty much instant effect on my mood, especially on my anxiety.
