I had my Bypass in Sep 27 2017, during the first 3 weeks I lost 30# but after that no even one more.. I am very frustrated... is this normal?

yes. Happens to almost everyone. Search this site for threads on the "three week stall".

EDIT: oh wait - so this stall has been going on for over a month? That's unusually long. The three-week stall usually lasts a week or two. Are you weighing and measuring what you're eating? Are you sticking to your plan?

It is not normal for your weight loss to come to a prolonged dead stop after the 3rd week. So you will need to investigate the cause. What type of surgery did you have? I had RNY gastric bypass and did not encounter a stall that lasted more than a couple days during the beginning. Sleeve patients tend to encounter more stalls and their stalls last longer. So you might consult your surgeon's office about this.

The three most important elements after RNY gastric bypass surgery are to meet your daily protein, fluid and vitamin requirements. Food is secondary because your body is converting your stored fat into the energy that drives your body. Thus you lose weight.

Weight loss is achieved after surgery through meal volume control. You begin at 2 ounces (1/4 cup) per meal and gradually over the next year and a half increase the volume to 1 cup per meal. With this minuscule amount of food, it is next to impossible to meet your protein daily requirements by food alone, so therefore you need to rely on supplements such as protein shakes.
