Skyesque, welcome!
Remember that SBD is NOT a low-carb diet but a GOOD carb diet. We don't try to eat less carbs (in fact, we don't care about the number of grams of carbohydrates we eat), we try to eat only good carbs and good fats. In phase 1, you are limiting your fruits and starches, but you are still allowed to eat things that are full of carbs, like beans, bell peppers, and tomatoes. In fact, you want to eat those to help you with your detox from sugar...they'll make it easier, and the beans will also give you fiber to keep you from having problems with constipation.
Make sure you are getting at least 4.5 cups of veggies daily. In order to do that, you really need to make them a part of every major meal (including breakfast) and at least one snack. If you poke around, you'll find tons of suggestions for ways to get your veggies in. How about putting some in your eggs and having some laughing cow cheese on celery or cucumber 'crackers'? Not only will veggies fill you up, but they'll give you nutrients which you really will need these next two weeks.
And drink tons of water...at least 64 oz a day. That's plain water (at most with some real lemon or lime juice added in)...crystal light and soda don't count. You want it to be able to be passed through your system without processing.
I definitely lost belly fat first, but I have the most fat in my belly (or had), so that wasn't too surprising to me. I lose all over, at weird times. All of a sudden, I'll find that my clothes are fitting better somewhere, and then it will be somewhere else. I had one breast that was a cup smaller than the other for a while!
Everyone is different, and you'll figure out what your body does as time passes. Good luck!
