You and your doctor should devise a diet which is best for you. Indeed, it may be helpful to think of it not as a 'diet' but as a new plan for 'healthy living.'

Diets, by their very nature, often end up with limited success since a perceived failure (falling off the 'diet' wagon) can lead to quitting in despair. A lifestyle choice to develop a 'healthy living' plan, therefore, might lead to more success since the focus is more on a healthy goal (with weight loss as a byproduct).

The focus is less on the numbers (weight as reflected by the scale) and more on your body's size and shape, as well as your medical numbers (cholesterol, blood pressure, etcetera).

If you decide to try it, I think you may find that a focus on "living" instead of "watching" (i.e., dieting) may lead to better results. Good luck!
