My hypothesis is that GLP-1 drugs are basically counteracting the effects of various chemicals interfering with the natural processes of our endocrine system. I think something (microplastics, chemicals in the water, hormones, ultraprocessed food, etc) is interfering with how GLP-1 is interacting with our body in the first place. So the GLP-1 Drugs is helping bring this back to normal. I think different people due to genetic differences are affected by these environmental factors differently, that's why two people can both eat the same food and one is still starving and one is full.
