There are four systems that we evaluate with consultation, examination and lab values: blood sugar and adrenal function, thyroid function, liver and gastrointestinal function and other hormones. The key is the up regulation of fat burning capabilities and the down regulation of fat storing capabilities. For people with stubborn weight problems, the approach of less calorie intake and more calorie burning with increases in exercise is not always the solution.
