Reddit has some of the largest and most active communities, with Facebook groups and Discord servers for more specific dietary approaches and accountability check-ins.
: Hive Index lists 6 Diet subreddits on Reddit. Most listings with size data are massive (67%) or huge (17%). We only have a handful of listings so far, so treat these numbers as directional. The main Diet topic page covers every platform we track for this topic.

: All 6 listings on this page are free to join (no paid membership or application gate listed). Access rules can still change on the community side.
: On Hive Index, the default Popular sort surfaces r/GLP1, r/tirzepatidecompound, r/Supplements, and r/Semaglutide first. Popularity reflects visitor interest in communities on the site, not a universal quality score. Use the sort menu for Ratings, Largest, or Newest.
: Listings are submitted by community builders and researchers, reviewed for topic relevance, and updated with platform, feature, member, review, and traffic data where available. Member counts are approximate. Popular reflects visitor interest in communities on the site, with richer profiles breaking ties. Ratings, Largest, and Newest use review scores, reported member counts, and listing age instead.
