I lost 20 lbs last summer and gained 10 of it back over winter. my goal is to lose 20 lbs this summer. my ULTIMATE goal is to get down to 140 lbs

I am 24 years old and will turn 25 on the 17th of May. After i graduated highschool i got hired at the job i'm currently at and started taking metabolife. i lost 20 to 30 lbs and maintained it until i had to stop taking metabolife. the manufacturer stopped making it. Once i stopped taking it i gained all my weight back plus 40 lbs in less than 4 months. it was a depressing time for me. several years ago i joined WW with my mother and lost 10 lbs. i quit WW and started watching my caloric intake and lost 10 more. Quakers rice snacks helped me do that and i'm very greatful.
