51 and looking for a fresh start

Options
I have tried so many programs over the years and desperately need to lose a lot of weight and keep it off forever. I'm an emotional eater and cave so easily for junk food. I have lost lots in the past and can usually lose weight fairly easily IF I stay on track with whatever program I'm using. Sugar seems to be my biggest weakness but salty foods are a big temptation as well. Life is pretty busy with 2 kids and homeschooling. I need to get to a much healthier weight.
