@greaterofer: Most people track calories. I track protein too as I aim to gain muscle mass even while I lose body fat. Once I enter my meals into my tracking app, I know exactly: * how many calories I’ve eaten * how much protein I’ve consumed * whether I’m still on track for the day You can’t manage what you don’t measure. For me, fat loss got a lot easier once I stopped guessing. #fatloss #nutrition #protein #longevity
