<human>: Can you provide a brief overview of the text?

it's one of the fancy ones, I got it at walmarts. It measures your weight, which wasn't the shocker, 262, I was guessing 260, so I'm apparently pretty skilled. the shocker? this thing does body fat % and water %. water weight 37.5, so yay, that'll be easy to drop. body fat...49%. I am DISGUSTED by that. it's absolutely appalling! I did ballet from kindergarten through middle school, so at some point, I had to have been somewhat muscular, but what did I have to do to get to this point. I've been reading the Lyle McDonald book on the ketogenic diet, and I think I'm going to give it a whirl. I've tried just about everything and I'm going to combine it with something I've used before, what lost me 50 pounds previously (yeah, I used to weigh 290, I was down to 240 and then I gained some back) so cinch+keto hopefully equals me losing weight and not being almost half fat. I'm disgusted with this.
<bot>: I found out I have 49% body fat and I'm disgusted at myself and going to do something, I could really use some motivation and tips and stoof.
