@gabriel I never heard of anyone who went vegan to lose weight. Maybe vegetarian, but veganism is not just a diet, it's a lifestyle. You have to give up any animal-based products (not just food) in order to become vegan. Some even refused to use lethal pest control.

Veganism failed because COVID was a wake up call for many people when it comes to mainstream science. COVID skepticism also lead to a rise of climate skepticism which probably took veganism with it, and it became clear that many people who were pushing it wanted a two-tier society.
