Hi Megan!
I could have made your post 10 years ago--I used to do the same thing. Unfortunately, I wound up at 17 weighing 330 pounds. Those afternoon binges are really hard because we're usually in a slump in the afternoon and craving carbs and fat and there's no stopping! This is a habit you need to break ASAP!
Some things I wish I had tried:
1.) Get OUT of the house. Stay late at school with a club. Go to a friend's house. Go for a walk. Get an afternoon babysitting job. Go with your mom when she picks up your little brother. Just get away from the food.
2.) Exercise after school. Any kind of exercise, even just a walk, is a great appetite supressant.
3.) Eat a big lunch with lots of protein and fiber. This will keep you full so you're maybe not interested in the snacking.
4.) Have a snack (again, lots of protein and fiber) right when you get home, when your mom is there.
5.) Talk to your parents and tell them that you're having a hard time keeping your eating under control and ask them not to buy unhealthy foods.
6.) Pick something you really like to do (talking on the phone, reading, doing your nails, a hobby) and save it only for the time when your mom leaves. Get as far away from the kitchen as possible and enjoy whatever you've decided to do.
Good luck to you. You can do it!!!
