Next day after hitting your goal, the starvation is still there. The desire to eat is still there. Hating working out is still there. But now you have to do this herculean effort every day not to get better. Not to lose weight. Just to maintain. Your brain wants you to gain 80 lbs and will never stop nagging you. Not on a good day. Not on a bad day.
Then something really shitty happens in your life. Like it does for everyone. You slip. Eventually you start to gain back the weight. You just want to die. You feel like a failure. You hate yourself.
That's the trick. Hitting goal weight the first time or two is relatively "easy". But you've achieved nothing if you aren't able to maintain weight loss. That's the failure of all approaches prior to these GLP1 and similar drugs.
Having set the scene, now compare it to semaglutide. You have a drug that regulates your brain. Gets rid of the constant nagging to eat. You get normal brain. You lose weight.
Now you have to pick, take a once a week drug for life to maintain, or do a herculean effort to fight the brain urges and work out to maintain.
Which do you think will be more successful?
