I went on the paleo diet strictly last year because I wanted to be able to do a human flag. I went from 230 to 155 in 7 months I'm 5' 11 so 155 was a bit underweight now I'm at a healthy 170 able to hold a flag for 7 seconds, i could not belive how well it worked. I still try and go by it but I'm not as strict. Stick it out and you'll have great results I recommend it to anyone trying to lose weight.
