I have a varied, aiming for low-fat vegetarian diet where I eat sometimes vegetables with a bit of bread, sometimes meat industrial substitutes (I try to reduce them), sometimes pasta or rice, sometimes tofu, sometimes leguminous such as lentils, chickpeas, split peas. I can have a bit of cheese, and usually eat soy "yogurts".
I have meals where I have very little protein intakes and other where I would have more than someone else eating meat. I eat very little for breakfast so I do two real meals a day.
I'm concerned about my equilibrium if I don't eat proteins for a day, but I'm really unsure when I should start worrying, and if eating more proteins the meal after "compensates" or not.
So how frequent and regular should protein intakes be?
