I did something a few years that worked for me..

Eat an apple 30 minutes before every meal (I did it mainly for lunch and dinner). It helps you to not be as hungry during your meals so you'll eat smaller portions. And for snacks have fruit or go buy healthy snacks from the store.

.. You know the usual, cut back on junk foods and eat fruit instead. Make sure for breakfast you don't eat something really high in sugar beacuse it makes you hungrier for the rest of the day. (So even though fruit is healthy, it has natural sugars so eat a bagel or toast with it. Or the white part of a boiled egg.. Just something else.)

Hope this helps. :0)
