You have multiple subsets of population that may find it more difficult to quit meat than the others.
For women (especially pregnant), meat is a source of Iron.
For people with adhd, there is a correlation with meat eating (and we can assume causation as well, since adhd is genetic). Meat is a source of vitamins that have been proven to help with adhd symptoms, and of course protein which helps with brain functioning in those cases.
Personally, I don’t do much sport, but I get occasional cravings so high that I could kill anyone who would want to prevent me from eating meat. Trying to figure out what is responsible, and which supplements can help, but still haven’t figured out.
With all the sympathy for animal suffering (my gf is a vegan fighter), just because you and some other people have it easy to quit meat doesn’t mean that it’s easy for all the rest.
