First step in order to lose weight you must burn more calories than you intake. This means keeping a calorie count throughout the day and you would be surprised at how many calories you actually do intake.
Step2
You must have an exorcize regiment to help burn off excess calories and keep from gaining weight. I recommend strength and weight training one day and the next cardio for 30 minutes a day, keeping this schedule allowing the last day of the week for rest and rehabilitation of muscle. Don't be afraid if a couple of pounds are gained in the first couple of weeks because muscle ways more than fat, so as your gaining muscle you will gain weight but eventually the muscle will burn the fat faster and you will loose the excess fat weight.
Step3
After getting to your goal weight you want to reach you must then find a Nutritional plan to get all your recommended daily allowances which are on the back of most food items and still eat the recommended amount of calories. Typically between 1900 and 2500 depending on male or female.
