I've been stall in the same weight for one month. What is wrong?

We may be able to tailor a response to you if you could provide more info.

What surgery did you have? How far post op are you? How long since surgery? How much weight have you lost since surgery? What is your current weight? Following your post op guidelines? What do you typically eat in a day? Drinking plenty of fluids? What exercise are you doing?

Generally stalls are pretty common and as long as you are following your post op guidelines the scales should catch up eventually.

I have a gastric sleeve. The surgery was last May 3. Since the surgery I lost 41 lbs. My current weight is 254. My highest weight was 316. I'm following my plan. I usually eat for breakfast one egg and a little bit of cheese, for lunch chicken (2 or 3 onces) and the same for dinner. Last week I started to have a snack ( Pure Protein Bar). I used to drink water and sugar free vitamin water. I walk at least 4 times a week maybe 30-45 minutes. I do like Zumba, cardio hitt workouts.

Stalls happen. And you will likely experience a couple of them as you’re losing. They tend to last 1-3 weeks but some people do experience longer ones. They can be very frustrating. I thought of mine as my body taking a breath to catch up with all the changes. It’s been going through a lot

Some people say increase your caloric intake, others say to up your activity. I never changed a thing & mine always broke.

Though this video from Dr Matt Weiner is in response to a stall when moving through the post surgical stages (the 3 week stall) it really applies to all stalls while we are losing. (The question is a little long.)
