r/fatlogic is a subreddit with 396k members. The most common kinds of discussions are pain & anger and advice requests, and the community frequently discusses fat, health, weight, body positivity, and obesity.
Fatlogic is anything that deviates from the scientific facts of body weight management. This can range from fundamental misunderstandings of how biology and physics work to lengthy political diatribes about how everything is society's fault. Falling victim to fatlogic means accepting misinformation that will harm efforts to keep your body at a healthy weight (or lose weight if you need to do so).
