I experienced a stall (and even gained 3 lbs in that stall) in my 2nd week after surgery. Like you, I was freaking the ** out! I was lucky if I was even hitting 800 calories with what I was eating, and walking everyday on the treadmill. There was no possible way anybody eating that little and doing cardio every day would not be doing what it took to lose weight. With or without the surgery. I made a post on here, did lots of reading and watching videos, and finally talked to my doctor's nurse practitioner (the doctor who performed the surgery). This is what I got from all of that:

Your body has a system that is calibrated between your weight and basic health, and this system is controlling your metabolism rate and hunger. When we lose a bunch of weight, this system detects that and thinks we're starving. So it slows metabolism way down, and will try to increase your hunger (good luck). So when we experience a stall, understand that it may be something you're not doing right, but it is much more likely that this system I described is doing its job and putting the brakes on losing anything. Once it stabilizes out and finds synchronicity with all factors involved, then is when you will start losing. In laymen's terms, when it catches its breath on the weight we are losing, it chills out and we start losing again (provided we're doing what we're supposed to be doing).

In my humble opinion, if I were you I'd continue to follow the plan but realize this is what is happening. Don't freak out and try to reinvent the wheel here. The whole thing makes sense if you stop and think about it. The body is an amazing thing. And if you graph the progress of losing weight on a daily basis, it will not be a perfectly straight line. It is in the very beginning, but for me it's starting to get much more slowed down, and I'm fine with that. A realistic goal I set for myself was a pound a week. If I lose more than that, freaking awesome! If I don't hit that, keep nose down and full speed ahead, it'll happen. I think our will power alone is something that is absolutely necessary to continue on this journey.

Lately I was not eating enough because my blood work showed very low proteins.

My personal goal for proteins intake is app 100-120 grams per day. And trying to have proteins at every meal, even if it is a small amount.

The most important is how are the results of your blood work? Are you at least maintaining your muscles mass?

For an adult male - I saw recommendation of 65-100 grams of proteins, but 2x as much during recovery from any surgery, or while weight lifting/ body building.

When my daily proteins intake is less than 80-100 grams, my blood work often shows deficiencies.

When at my goal weight, or below, and I need to make sure my body doesn't use the proteins as energy. I need to make sure my meals have more proteins and other foods my body can use as fuel. I often pair my proteins with fat, i.e avocado, mayo, or even butter to top my steak with it.

Do you weigh and log every bite that you eat, down to the fraction of an ounce?

If you do, and your calories are under 800, and carbs are low, keep doing what you are doing. It will happen.

If you aren't weighing and logging every last taste, you are just guessing at how much you are eating. Guessing will always lead to slower loss, regain, and lots of sleepless nights.

IMO, the first 28 lbs loss was not realistic loss. Some may have been water that since then your body got back in and since then you lost the real weight. During my first month I lost app 12 lbs, the following month, app 10. Soon 2 months I lost less than you did.

Some people lose in stair-step type pattern. They lose a bunch, them nothing, them lose a bunch. Not the weekly or even monthly loss but a total loss, average loss is important.

If I lose 10 lbs in 1-2 weeks, I may expect next 2-4 weeks to be without weight loss but my body would change the shape and size. That is expected. Be patient. That's what you need.

Many people share your frustration. Look a the forum on this site for 3 week stall. Many people experience it. It is vital to track every morsel you put into your mouth. It is very easy to take in more calories than you think. Weigh and measure everything. There are many phone apps you can download for this purpose. Fat Secret, My Fitness Pal, Baritastic, to name a few. At this stage you should really only be taking in approximately 600 calories. Everyone varies but that is on the high side for your stage post-op.

You did not talk about your fluid intake. This is the most vital. At least 64 ounces a day. That is the minimum intake. Evidence has shown that we excrete fat from our bodies through respiration and through urination. Try increasing your fluid intake (you can count protein shakes as fluid) and be aware of everything that passes you lips.

You can do this. Your body is recovering. Try not to be discouraged. You took a brave step to better your health. It will pay off if you are able to stay the course and keep coming to this website for information and support. All the advise here was very helpful to me and can be for you also. Best of Luck, and be kind to yourself.
