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)?

You can but they’re not particularly good for you. I recall in there was a pretty effective drug called fen-phen which increased metabolism and suppressed appetite but ended up getting pulled off the market because it was giving people in their 30’s heart issues.
Technically any stimulant will increase your metabolism somewhat, most diet pills are just caffeine which does work but probably not to the extent you would want. One of the main issues is that your body adapts to any drugs; if you’re longtime coffee drinker then you’ve probably noticed the effects firsthand. Take a drug that block receptors and your body will ‘upregulate’ new receptors; take a drug that activates receptors and your body will ‘downregulate’ those. So even if you find a drug that doubles your metabolism on the first day; after a few years, you would have a much slower metabolism without the drug.
