As someone who reentered the dating world a few years ago, I never fully understood the concept of red flags. And then, suddenly, I understood the dialogue. It seemed like I was in a parade, and red flags were readily available and in abundance. But dating doesn't have the monopoly on red flags. Our bodies often wave a giant red flag in front of us, and we seem to be colorblind to it. But I want to draw your attention to calorie deficit red flags, how a reverse diet can address those red flags, and whether a reverse diet may be appropriate for you.
