What the expert does: “I write a friend every day to tell him what I eat and do for physical activity.” -- Mike Roizen, MD, chief wellness officer at the Cleveland Clinic
Why you should do it: Writing down what you eat and how you exercise keeps you honest. There’s no way to pretend you didn’t eat those M&Ms if you’re keeping a food log! Plus, writing down what you eat makes you more aware of exactly what and how much you’re eating, which helps you make smart food choices and control portions. Sharing that information with a friend means you’re held accountable, plus you get support. Studies show that keeping a food journal and buddying up increase weight-loss success.
