Keto diet community vs method-agnostic weight loss

r/keto is for thoughts, ideas and experiences around a ketogenic, low-carbohydrate way of eating. r/loseit is for people of all sizes discussing healthy, sustainable weight loss by any method.

Both have SubMouse pages (keto about 4.0M, rank #241; loseit about 4.2M, rank #223). Samples are all text; loseit is far busier in our window (roughly 72 vs 11 posts per day).

Collected titles: keto asks members to read the FAQ first, stay on topic, avoid cheat posts and low effort, and bans giving or soliciting medical advice. loseit emphasizes civility and bans diet cash pools, self-promotion and surveys. Choose keto when you are following or researching a ketogenic diet; choose loseit when weight loss is the goal regardless of diet. Neither replaces medical advice. (loseit vs Fitness covers the training side.)

  • r/keto: ketogenic eating; FAQ first; no cheat posts; no medical advice (collected titles).
  • r/loseit: any sustainable weight-loss method; no cash pools or surveys (collected titles).
