You have to want it more than you want other things.
Start low and go slow. A couple changes here or there. Nothing too drastic. Try doing just 15 minutes of intentional movement (stretching is a great place to start) and count your calories. Maybe replace drinks like soda and juice that contain calories and substitute low or no calorie drinks.
@Doomflower I don't drink juice or soda all I drink is water and if I have a craving for soda I only drink ginger ale. I totally agree with you my problem is just emotionally eating and its hard because I have an anxiety and stress disorder but im learning to channel it more into art instead of eating
@AlienPrincess I feel you because I am just the same!!! I found a lot of joy in coloring, drawing, folding origami, and juggling as all great ways to keep busy. Also video games but I hate sitting for too long.
