How is this any better than counting calories?
Although you can technically still count calories to drop pounds -- "calories in and calories out are the big picture in weight loss," according to White -- this is 2016, and everyone realizes that not all calories are equal. As amazing as it would be if 200 calories of broccoli were the same as a 200-calorie donut, they aren't, so don't try and kid yourself.
"Keeping track of just calories as opposed to what makes up those calories can be harmful to your body despite the weight loss," White explains. "With counting macros, on the other hand, you are fully aware of what you are putting into your body and you're keeping track of very precise numbers of those nutrients."
Consuming all of your calories from just one or two macro groups can also throw off other internal operations: blood sugar, hormone levels, and muscle mass, even if the scale isn't budging. If you just ate donuts, for example, you're also loading up on the simple carb sugar, which can cause all sorts of problems. Macronutrient tracking does require some common sense -- getting your carb macros doesn't mean from simple sugars or alcohol, unfortunately -- and focuses on consuming a well-rounded diet. "It's all about quality of nutrition," he says.
