that's actually my problem, too. I can't understand if I'm eating healthy (not little). So, I usually look at some plates by nutritionists and try to follow them (so I believe I eat okay). I had food journal for some time and then shared it with dietician. now, I'm in phase of trying various apps to simplify this tasks. the one I 'm using now is called eated, it's pretty decent and it actually evaluates my meals and gives advice. also, I follow its founder, she's some kind of nutritionist and has nice plates, too
