When you lose weight without building muscle you become a “smaller” person. And as such, you have to eat fewer and fewer calories (otherwise you’ll go right back to the same weight you were). But muscle changes that. It makes you expend more energy, and it requires you to consume more energy to grow.
Muscle not only ups your metabolism it also makes you look leaner. No matter how much weight you’re carrying, muscle will change the shape of your body like nothing else. And in order to have muscle definition, you have to have muscle. There’s no way around it.
