Sorry to say but, you cannot lose 100 pounds in one month. You can however lose at least 10 pounds. Though it might not sound like a lot it will get you started on your rode to weight loss. What you need to do is start slowly. Try to eat half of what you usually eat or even better, cut out all junkfood. At first you might not want to excersize and focus just on eating habits. But you can gradually start excersizing. Excersizing doesnt have to be running 10 miles or all that Jazz, excersizing can be as simple as doing a few jumping jax or shooting some hoops. Remember this ~EXCERSIZE IS ANYTHING THAT GETS YOU OFF YOUR BUM~ People think that you have to run 10 miles to lose weight WRONG. My advice for you is to work your way in to it. Start really slowly NOTHING TOO DRASTIC. Dont check the scale everyday because it takes a week to lose about 2-3 pounds. When you feel like your not getting anywhere then take it up a notch. The weight will come off I promise. Your will feel like a new person after a while of good excersize and healthy eating. Just remember Gurl have fun... I wish you the best of luck NEVER GIVE UP. R u a fan of Aaliyah? I know I am then listen to her "Dust yourself off and try again" Much luv ~Leslie~
