New to MFP!

Hi,
Living in PA and decided yesterday was prep day and today begins my journey to be 50lbs lighter! I gained after my sister tragically died suddenly in 2015 and would like to be healthy for a walk I'm preparing for that's a month from now. I'm not setting a lose this by date because been there and done that. I'm glad I have an Endo physician who pushes me to make healthier eating choices.
Thank you guys for the encouragement to meet my goal!
