New here and New to LCHF!!

Options
I'm super grateful that this community is here. I'm 1 week into a LCHF diet at the suggestion of my Dr and have about 75 lbs to lose. My start weight was 251.4 lbs and today I was 246.2. I lost 100 lbs about 20 years ago and kept it off for about 10 years but the weight crept back on in the past 10 and here I am again. First time was low fat low cal. Now High Fat low carb. I'm 43 and no longer want to carry around an extra human!!
