Giving out all of my points, before i delete my account.
why is starvation bad?

Starvation is bad because it makes your body unhealthy. if you don’t have a healthy diet you can age faster or even die before you’re 30.

Well if you pick a machine to work on and that's gonna be your exercise if you don't stick to that machine your muscle strength your muscle mass rather will change because you haven't been doing it you change something in your exercise routine which changes your body's form of dealing with things for example you might become weaker or stronger depending on what kind of exercises you do in whether or not the machine you picked actually your muscles grow.
