So I'm thinking of switching to a keto diet, but I'm imagining it'd be pointless, because I'd drop about 10 pounds the first week just in water... then 1-2 pounds per week... then come off keto, rebounding about 10 pounds in water... and really only keeping OFF, the 1-2 pounds I lost per week... which I would have lost without keto... but maybe I'm terribly confused.
