Weight-loss drug found to shrink muscle in mice, human cells

If you’re 20% smaller, it would make sense that your heart could pump 20% less.

Uh, I think most highly in/shape people have normal sized, very healthy hearts and their bpm is like 45.

Their hearts are not physically smaller, nor did they shrink during their build-up to current physique.

Saying things like this is harmful at best. Please don’t.
