Starting with healthier eating habits can seem daunting at first. Switching from eating junk food can be incredibly stressful for some people. I believe the best way is start with gradual changes to your daily diet. Maybe by including breakfast. Try cutting night snacking, making healthier versions of your favorite meals (trust me there are healthy versions of them somewhere on the internet). Begin with one thing for a week and take small steps into the right direction. You can do this! I have complete faith in you!
