If you starve yourself, eventually, you’ll look leaner.
I’m sure you’ve seen pictures of starving people in poor parts of the world, or worse, during times of extreme hardships like war.
Of course if you are looking to lose fat, build muscle, get stronger, and look healthy, you’ll need to eat food in order to do that.
There are no examples that I’m aware of in which starvation built strong bodies.
