I'd describe the effects as basically the opposite of self-torture. Self-torture is dieting/fasting without the drugs. With them, it's great. No afternoon light-headedness and difficulty concentrating, no hunger pangs, no "hangry" effect, no cravings you have to keep suppressing. Just smooth sailing. (though experiences do seem to vary—as do dosage levels)

That's true of semaglutide, but newer peptides like tirzepatide (a dual-agonist) and retatrutide (a triple agonist) have additional effects like improving insulin sensitivity, and simultaneously slowing the release of glucagon and activating glucagon receptors, which directly increases fat oxidation and thermogenesis.
