33 years old and ready to shed the weight

Hi all, 

My name is Lisa. Keto newbie/convert here. I was misinformed for years about this system and never considered it. I have a about 180 pounds to shed - Im so ashamed that I ballooned to the size I am (388). I am an RN, in good health aside from my weight surprisingly - under this ton of fat I'm strong and have okay muscle mass. I do like my weight impacts my mental health though - It holds me back from really living life to the fullest. My GW is 200 but in the short term I would like to be to 350 by Sept 1. Start day is today! Pic is my last selfie taken about a month ago.
