Looking for accountable buddy

I am a 45 mwm overweight. Looking to lose weight. I have gone tired diets and fades in the past, juicing, salads, etc. I don't have a set plan YET, other than eating better and less, avoiding sugars and processed foods. I would like to lose 50 lbs or more. I am tall and carry my weight well, but it does hide the fact I am on high blood pressure meds, and have low engery levels.
I would like to find a buddy or buddies for support to cheer on with. Maybe exchange body and food pics. Someone to be honest with. Male or female. Along with this app I wear a Fitbit.
