This works well for me, but I do have to warn you, you are going to need to be able to exert some self-control. Start off the morning with a cup of tea, whole grain cereal, and some sort of fruit, like an apple, pear, or orange. You CAN eat bananas, but they tend to fill you up more and will keep you from being hungry for lunch....which if you push back lunch might throw a kink in your eating schedule. (Try eating half a banana with meals or in between....apples are best in my opinion) For lunch, eat a well balanced meal, sandwiches, pasta....any number of things are okay....make this your main meal of the day. Don't overindulge, but it's okay to have pasta or a baked potato. Then for dinner, eat another bowl of cereal. If you get hungry in the evening before bedtime, eat another piece of fruit, again-apple, pear, orange....at this point NO bananas, and things like watermelons have a high water content, which can be okay, but personally for me, I find they don't help with weight loss.
Throughout the day, drink plenty of tea, which is a natural diarrhetic, and will help to keep your body regular and flush your system out (no, not uncontrollably...more comfortably and in a totally healthy manner), while providing all sorts of antioxidants. Both green and black teas are good for you. Coffee is okay too. Drink plenty of water, which will help flush your system, as well as help you from feeling hungry. Also, replace ALL sodas....completely cut them out....even the diet ones. Replace them with juice. Lots of people criticize the high sugar content of juices, HOWEVER, you get your fruit servings which ARE important, and the type of sugar boost you get is natural and long lasting. Even calorie counting, I find that if I exceed my daily allotment of calories, if it's due to juice intake, it doesn't react negatively with me, and in fact, still aids weight loss.
Plus, the natural sugar boost will aide you in the necessary exercise you WILL need to do. I don't go the gym or run...I walk....EVERYWHERE. I walk my kids the mile school, walk the additional 1/2 mile into town. After dinner, take a stroll around the neighborhood. This will maintain muscle and tone, while not building, and burn fat. It might take a couple of days to get into the swing of things, but you will be surprised at how quickly the weight will start coming off. Even if you don't see improvement on the scale right away, you WILL notice it when looking in the mirror, and then the scale will follow quickly.
Best of luck!
