Carbohydrates are the macronutrient that fuels your body. In fact, they represent over 50 percent of America’s daily calories. Carbs are a complicated mixture of sugars, nutrients, fiber and calories. But all carbs are not created equally. Too much pasta, cookies and starchy carbs can lead you down the road to stress, weight gain and overall poor health. So, when I found myself packing on the pounds, depressed and retaining water due to a sluggish thyroid, I decided to go cold turkey — literally.
I've been eating a high-fat, carb-restricted diet for almost 20 years, since I started as an experiment when investigating nutrition research for the journal Science. I find it's easy for me to maintain a healthy weight when I eat this way. But even after two decades, the sensation of being on the edge of a slippery slope is ever-present.
