Elana, I love Core and have been doing it for almost 2 years. I need to lose another 120 pounds but I've not been exercising or I'd probably be darn near there by now.
I eat Post Shredded Wheat and Bran or oatmeal every day for breakfast. I, too, enjoy fresh fruit in my cereal. I'd advise this brand and combination of bran as I've found it to have the best flavor. I like to cook fruit into my oatmeal as well. I use the quick cook (not instant) and make it with milk instead of water since it gives it a creamier texture. If the fruit is fragile, like blueberries, then I stir them in at the end. I cook mine in the microwave. If it's heartier fruit then I put it in near the end of the cooking time when I'm stirring. I heartily recommend a banana cut up in the oatmeal. If you REALLY use your imagination, it tastes like a banana muffin.
We have many, many great recipes here. I have a couple of Core tips. I'd suggest that you try it for a month. Sometimes it seems that it takes folks a while to drop a big amount. Water is WAY more important on Core for some reason. It must be all the fiber we are eating that needs to get washed through. I drink at least 6-8 eight ounce glasses of water daily in addition to other decaf beverages. We have also found that some type of exercise helps. I'm sure this is true on flex as well. I think it's very important to eat 3 small meals and 2 snacks. This helps me to only eat to satisfied as opposed to full if I know that more food is coming around the corner! IMHO, I'd try to stay away from sugar if you can until you detox a bit. You can use your WPA's for sugary things if you want but we've found that a little bit of sugar just makes us want MORE!
Ok....I've babbled all I can think of. I hope some of it helps.
Come hang out with us on our weekly chat thread. We love new people! I'll bet you'll see a quick loss if you just change the kind of food you're eating for a couple of weeks.
