Workout at least 30 minutes a day. Your burning carbs for the first twenty minutes of cardio, and fat for the other ten. This is the most important thing, you need to work out. I'm not saying bust your balls on a gym membership, but seriously try and input at least that much time into your day strictly for cardio. Biking and stairstepping work great for this until you lose more weight and can start jogging. There are a few things you can do at home if you dont have access to these: Push-ups are great, crunches are great, and squats are amazingly useful. It will be hellish at first to get started, but trust me 2-3 months into a real workout program and you will feel way better than you thought you could. Remember: Muscle weighs more than fat, so if you start bulking up and have a weight gain, dont be discouraged at first, because muscle also BURNS calories just by being muscle, fat does not do that. Do a daily food log, do not fail to write anything down. Even if it is a handful of peanuts, or a cake, or a single smartie, write down EVERYTHING and analyze it. Stop any kind of white bread you are eating, white bread is basically bread without any nutrients and "bad" carbohydrates. Do NOT diet, diets do not work. You restrict your body of the calories it needs and you WILL slow down your metabolism and gain weight, period. Instead, replace fatty meals with healthier meals, and stop snacking on fatty foods and grab an apple or a fruit isntead. Take your vitamins daily, make sure you are getting enough protein, ect. Another thing: Stop the soda. Completely. Do not drink any more soda, whatsoever. Soda contributes to weight gain in ways you can not even imagine. One soda a day, 365 days a year. There are ~ 100 calories in a doctor pepper, thats 36,500 calories in a year. This is TEN pounds in soda alone! It is going to be really hard for you to change the first couple of months, but after you do it is like you never did anything different, trust me =) Hope I could help you :-)
