This is my concern as well. At 204 lbs + cholesterol of 347, I have lost 6-7 lbs in my first four days. What will happen when I finish the injections, I wonder. I can say that Stevia is a wonderful replacement for Splenda. I plan to do meat and veggies M-F, in anticipation that carbs are not my friend--which of course I crave. If I feel deprived I will regain any weight I have lost.
