IMO that is a terrible diet no offense. Lots of processed carbs with little to no poly/monounsaturated fats and barely any protein.
Patrick wrote a good article about setting up a diet for beginners here.
I'm not sure anymore if he mentions this, but FitDay - Free Weight Loss and Diet Journal is the best thing to happen to dieting since sliced bread.
Some may find it difficult to keep to a caloric range with macro guidelines etc. I like to ease people into lifestyle changes by teaching proper food choices (unprocessed carbs, lean protein sources, poly/monounsaturated fat), portion control (measure your food somehow, use a scale or use a cup measure and go by volume. Point is you want to start getting a feel for how big a 5oz piece of chicken is or a cup of rice etc), label reading, food awareness (I use this term to describe knowing, for example that chicken is Protein, Rice is Carbs, Oils are Fats, Peanut Butter is a mix and so on and so forth. It seems simple but you'd be surprised how many people are clueless about this stuff and ask me all the time, "Did you know a banana has Xg of Carbs?"). And the final thing I can think of is balancing meals, to keep it simple in the beginning and not scare people away, you basically tell them to get in a carb, a protein and a fat. The plate division thing is great to teach meal balancing.
I want to re-iterate the part about easing her into this stuff, and making it clear that this is a lifestyle change not just a diet (re-inforce the hell out of this point). In some time this type of eating will become a routine and then it will become second nature, but I find its always better to introduce it slowly or you wind up scaring people away.
