Perhaps we should start with "what are you doing?"  how much did you start at?

My start weight was 349, I lost 25 pounds before surgery and 35 in the last 7 weeks.

I don't know if you think that is so great or not, but my Dr. has me doing this:
No carbs, Exercise 1 hr a day (If I actually did it all, I would have lost more by now), Drink 80 oz of water, Vitamins, One protein shake, eat 2 times at least 6 hours apart (I can eat about 2/3 cup or less), I can also have a nibble or two of cooked veggies.

My doc says don't count protein, fats or calories.  He says most of us have enough stored fat for 6 months. 

That's it in a nut shell.  Each of these docs has such a variance on their plans.

Let me know what you are doing.
