What’s the difference between LC, Keto and BSD?

[Innishh]

Are they all on a spectrum - one softer at the softer end - another on the more extreme end?

Do they also vary by results and sustainability?

Lc can be anything 150g net carbs or less.
Keto high fat low protein 20g net carbs.
Idk what bsd is.
