Why is metabolism something that cannot be greatly increased

Question

I know metabolism can be increased, or at least maintained by weight/ resistance training, proper sleep/diet etc..

But why can’t we just medically increase someone’s metabolism by say 30% (temporarily)?

Answer 1

Your thyroid regulates your metabolism. If you increase your metabolism, even for a short while, it could cause permanent damage to your thyroid. It’d be like driving your car at 7500 rpm. Eventually it’ll blow your engine.
