Eating clean doesn't mean you don't' have to moderate how much you eat but over all it's better for you ... you're cutting out long life and processed foods for a start.
Food eaten more in their natural state is typically less calories and all the rest that come with food. Eating 100 calories worth of fruit would be much better for you than eating a cake that is 100 calories .. why? Fruit is natural sugar, provides nutrients and health benefits whereas cake is filled with added sugar, white flour, processed carbs and no nutrients really which will follow with a sugar high then a drop which leaves us reaching for more snacks.
Clean eating should leave you feeling great and snacking less when you are filling up on good foods ... less added. Always read labels.
I do try and eat clean and do feel better for shifting out so much crap I ate for easiness.
Water ... keeps you hydrated, dehydrated can cause headaches and lack of enegrty and thirst is often mistaken for hunger but don't forget drinking lots of water is good for our skin too
