What people are saying is...why is there such concern for the supposed side effects of these particular drugs and no others. And no one seems to be able to answer.
First, I have never needed to lose weight in my life so jealousy doesn't come in to this.
These drugs and no others is because the people taking them when they are not diabetic are paying for the privilege of being a test volunteer, taking a drug which has never been tested for that purpose, many without any medical supervision. And hard as it may be, there is a drug free alternative for most people.
The long term effects are not known and potentially may include epigenetic effects (which is what peptides do) that continue down the generations long after the original users stopped using them.
The results coming in now, in the papers again today, are that most of the weight is regained within 14 months of stopping, and what risks there are will have been taken for no long term gain. Worse, they leave the person who took them in worse shape, body composition wise, than they were before.
The concern among many of us is genuine, perhaps not for individuals who we don't know, but for what widespread use of a drug to suppress appetite as a substitute for healthy eating says about where we are as a society already full of people with eating disorders (I was one.)
The sheer level of defensive reactions from people who profess to be perfectly happy taking them suggests that claim of perfect happiness with the use of GLPs is not actually true for everyone.
