Cuz if this is the truth im stuck with my weight for a while what can i do to help this

I got the following off of webmd.com

If you don't keep this emotion under control, it can make you fat. How? Getting riled raises levels of cortisol (a stress hormone) in your body, and that increase can cause you to gain weight. Plus, research suggests that the angrier you get — and the more frequently you get angry — the more likely you'll be to put on pounds around your waist. (Hostility also ups your risks of cardiovascular problems.) So the next time someone pushes your button, take 10 deep breaths and ask yourself, Is this really that big a deal? Another trick I teach my clients: Close your eyes, slowly press your thumbs into your temples, and massage the frustrating moment away.
