New here

Hi, everyone, first time here ..want to lose 50 lbs...need all the tips I can get. I am in my mid-40's with arthritis so I plan on taking it slow. Just quit smoking after 30yrs ( 3months as a quitter) .Have motivation to do it, my first husband(divorced from many yrs ago) died from a massive heart attack 2 days after his 50th Birthday and I saw what it did to my children especially my son(who found him). I want to get healthy for my 4 children & 5 soon to be 6 granchildren!
