Is it possible for me to keep a steady weight?

Lifestyle refocus: Find a fitness activity that you enjoy and a group of people that you like and who'll do it with you. Push yourself and you'll win their respect and friendship. They'll guide you and you'll enjoy this more than greasy / sugary / salty food. Your brain will reset from hard exercise and guide you reliably about eating right for your body. This is a great gift to give yourself and those who love you.
