I had starvation mode problem after gastric bypass because I couldn't eat. No you do not lose all the weight just with surgery!!! My hair fell out, I was dizzy. Now Im on Atkins to lose last 26 lbs and my Metab is a snail because it adjusted to the amount of food I could eat. I have to adjust the food portions obviously but I am losing slow. Up the calories and or carbs to no less than induction on Atkins. 20 Carbs. You might want to try some allowed dairy cottage cheese, with No sugar peaches to help up the calories. I like mandarin oranges on my salads also. Watch the sugar content. Adding fruit will get your carbs up quick. You go too low the body slows to save up for starvation (thanks a lot huh?) You will do no good lowering the calories further. Also I find if I have a treat meal or have a Sarah Lee cheesecake bite, it kicks in losing again.
