Ten years ago, almost to the day, 80 lbs overweight, and faced with a diagnosis of sleep apnea (on top of high blood pressure, high cholesterol, pre-diabetes, and a bad back), I struck a bargain with my doctor: I would lose twenty pounds, and he would take the dreaded CPAP machine off the table. He agreed, and ten days before Thanksgiving — because why make it easy on myself? — I started eating at a deficit, and began the process of totally reforming my diet. A decade later, I’ve kept the weight off, and “cured” myself of various ailments. I’ve kept the fat off, and added some substantial muscle, in part by not sweating the holidays. I THOROUGHLY enjoy a ginormous carb-heavy Thanksgiving feast every year (and on other occasions!) with friends and family; but then I get right back to healthy moderate eating. And I try really, really hard not to slack off at the gym.
