Over last summer I lost about a stone and a half (21lbs...ish) Just through eating about 6 times a day and only healthy foods keeping note of how much fats, carbohydrates, protein I was taking in.
I think my most eaten meal over the entire summer was sweet potatoes and tuna

Lovely
A good source of dietry stuff that's pretty well grounded and from a lot of people who specialise in nutrition can be found on:
Bodybuilding.com - The Future Of Bodybuilding! Huge Bodybuilding Site.
I definitely recommend reading a few articles on there, it helped me lose a few lbs (although I have subsequently put them back on again from eating a lot of chip shop food

I hope that helps
