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

You can. It’s called exercising.

Other options include stimulants like caffeine, ephedrine. But most of these will only increase your TDEE by like 5-10%. 30% is a lot. There is a drug called DNP, but it’s very dangerous and can kill you pretty easily. People tried using it under medical supervision for weight loss, but it was too dangerous.
