One could even argue food is a lifetime chemical dependance. An assortment of chemicals really with the amino acids, lipids and sugars involved. People who are against these medications typically draw arbitrary lines for what treatments are "acceptable".

Until starting tirzepitide I always thought about food, now I don't. Had depressive issues since I was a teenager as well. I took Wellbutrin for 20 years and had an interruption in the last six weeks due to an insurance issue. Payed for the tirzepetide out of pocket, take that once a week, my depression is manageable without the Wellbutrin for the first time in my life. I'm still going thru depression, but that's due to my husbands death in early March. If I wasn't taking my weekly shot I would easily be morbidly obese and probably suicidal. The cost isn't an issue either, I would spend more on food that I'm not buying or eating each month than it costs to buy the medication.

Just because something might not be interesting to someone doesn't mean it has no value. I have no interest in sports, but that doesn't mean they shouldn't exist. I could argue they shouldn't be as prominent in society but that's a different argument.

If you have struggled with your weight, depression, have early warning signs of cardiac problems and a range of other conditions it can be worth considering semaglutide or terzepitide. As long as you stick to the lowest dose that's effective the side effects are minimal to non existent. Categorically dismissing these drugs is as silly as refusing pain meds because "god designed us to experience pain".

I think you dislike the personal responsibility angle, which is fine but separate from caloric intake being the source of obesity. The fat is stored energy from food, it would violate conservation of energy otherwise.

There's metabolism, food density, food availability, psychology, culture, economics, etc in play, but it's important not to lie to ourselves that the proximal cause of obesity isn't from over consumption.
