How this list is built
Subreddits are grouped into topics by what their posts are about; this list holds the weight loss group. We include subreddits that are safe for work and had at least 30 new posts in September 2026, about one a day.
Members is Reddit's subscriber count; growth compares it with a year earlier. Posts with a reply is the share of posts that got at least one comment over the last three months. Median author age and women are estimated from what authors say about themselves, and shown only when enough of them did. New-account posts removed is the share of posts from accounts younger than 7 days that were removed; communities at or below 17% are marked new-account friendly. Min. age/karma means the subreddit asks for a minimum account age or karma before you can post.
The list is rebuilt every month from public Reddit posts and comments. Data and CSV are free to reuse under CC BY 4.0 with a link to this page.
