JJ Virgin says muscle is denser than fat and burns more calories, so focus on gaining muscle and losing fat rather than chasing a lower number on the scale. She calls muscle "metabolic Spanx" and recommends using a bioimpedance scale to track lean muscle and fat loss instead of a standard scale.
So I like to say it's not what you weigh, it's what that weight is made up of. And the reality is you want to be a heavyweight. You want to weigh as much as possible for the size you want to be, which means that you're going to have more muscle, less fat, because as you know, muscle weighs more than fat. But it's bigger than that. Muscle is also more metabolically costly, which is why— that's why I call it your metabolic Spanx. It holds everything in tighter and supports a better metabolism. So what's the takeaway here? Don't just use a regular old scale. Use a bioimpedance scale so that you can track your progress and ensure that you're holding on to or building lean muscle as you're losing body fat.
