by Mark Bittman
Six years ago, an overweight, pre-diabetic Mark Bittman faced a medical directive: adopt a vegan diet or go on medication. His solution was a deal with himself. He would become a “flexitarian.” He adopted a diet heavy in vegetables, fruits, and grains by following a healthy vegan diet (no meat, dairy, or processed foods) all day. After 6:00 p.m. he’d eat however he wanted, though mostly in moderation. Beyond that, his plan involved no gimmicks, scales, calorie counting, or point systems. And there were no so-called forbidden foods—he ate mostly home-cooked meals that were as varied and satisfying as they were delicious, but he dealt with the realities of the office and travel and life on the run as best he could.
