You can do that for free.

self control is too much for these people.

They also miss out on the ancillaries of losing weight or maintaining your weight: learning how to manage your intake, learning when you are full, understanding food nutrition, cooking for yourself, learning to deny yourself, and the self discipline character building.

But these people likely dont understand character building at all so it is nonexistent to them.

Taking a drug is an empty gesture, you skip the work required to get the outcome you want, and you skip to the end...... with side effects just now being discovered.

And they learn nothing about themselves while taking the drug, so they go back to being their fat selves if they stop.
