The question "what can I do about this thing affecting me personally?" and the question "what can the group do about this thing that is affecting the group in large numbers?" are going to have quite different answers. I'm glad you've found a solution that works for you, but there's a good deal of data to support that telling this story to more people will not fix the group problem.

Even if your obesity was helped along by plastic based endocrine disruptors or micro-biome based issues or weird viruses, you found a solution for you.
