To lose weight, you need to combine exercise and a good diet. Your diet should consist of lean meat, whole grains, plenty of vegetables, fruits and water to drink. Eat many times in smaller portions during the day to keep your metabolism steady. Fins an exercise work out to follow at least 4 times in a week. Running, swimming and even cycling will help you tone as you exercise.
Exercise, exercise and exercise. Every day, no excuse. Jogging is probably the most helpful, but any cardio exercises are good. And follow an appropriate diet rich in fruit and vegetables and low in fats and sugar.
