First, see doctor: If calorie-counting skills are good and willpower is even greater, then a person can lose weight no matter what type of food she eats. That is because she will stop eating when she hits the maximum daily number of calories she allows herself. First, a check-up with one's primary care doctor to rule out hormonal problems. Ask if the doctor is ok with 300 calories, 4 times a day, equals 1200 daily.

Dietician: Have at least one consultation with a dietician at your local hospital. You will be told your realistic ideal weight, ideal daily calorie intake depending upon your usual physical activity level. You have to eliminate 500 calories a day to lose 1 pound a week. Your eating habits will be critiqued and sample diets can be given. However with your degree of obesity, you also need medical evaluation.
