Yeah, I highly suggest, as with most ladies, not to just jump right into a strict diet straight from a bad one. You'll get tired of it way too quickly and opt back into your old habits. Trust me on that one. I'm proof. LOL. It is hard (and expensive!) to eat healthy, but in the end, it is all worth it. Every time someone asks how I keep so strict on my diet, I always say "because great abs are made in the kitchen." And it is absolutely true. And it is okay to have cheat meals. It'll probably make you feel like you're messing up (which could be a good thing) but your body needs a slip up every now and then to keep that metabolism in high gear. I usually have one once a week. Sometimes just once every two weeks. And when I say meal, I don't mean day. I don't mean you have the whole day to eat whatever you want. Just one or two meals out of that one day. Or it may be just a snack for you. Like a candybar you've been dying to have.
And also, like thandie said, I highly suggest putting fish oil into your meals. You can buy fish oil pills at your local walmart or walgreens. Just about anywhere, really. In the diet/nutrition section. Other than that, I don't really have much else to say. Just keep up the good work and you'll get to where you want to be!
