Yes it does, as others have said breakfast is the most important meal. But if you are like me and find it hard to eat loads in the morning, just make sure you eat something filling and not too sugary. I think porridge is the most healthy but also museli. If you dont eat breakfast you will just be starving mid morning and are more likely to eat junk to get a quick fix.
Forget about being on a diet, just change the things you eat forever to loads of fruit, veg, non processed food and healthy snacks like nuts, seeds, natural youghurt, salad etc
Drink loads of water and always have a glass before a meal. Eat slowly and stop when you are full. Dont forbid yourself anything, if you eat well the occassional treat is ok!
Oh yeah and some exercise too!
