I guess this is an odd question, because I know every single one of us is different, but what is a reasonable expectation of weight loss every month? I see everything from 40 pounds in 6 months to 100 pounds in 6 months. That's such a huge gap. I just don't know how to know if I'm "on track". Has anyone here researched this or found a website that sorta answers this question?

Bigger people will lose weight faster. I have lost 56 pounds in 2 months. I thought I was doing something wrong cause I wasn't losing a pound a day like I was on the liquid diet. Turns out we are all different and you shouldn't compare yourself to others. The best thing u can do for yourself is put the scale away. Weigh like every other week, so when to u see a loss on the scale it will be a reward instead of discouraging when you have weight fluctuations. I had to do this. A couple of pounds a week is realistic.

I researched this very topic for months. The doctors, the surgeon, nutritionist, nurses, none of them would give me any numbers as far as a goal weight, expectations for losing,

Between the 2 different support groups I go to, I realized why. We go from one extreme to the other so trying to average these numbers is only going to discourage those who aren't losing quickly and un-motivate those who are exceeding that "average".

As for determining whether you are on track:

I'd highly recommend taking all of your measurements if you haven't done so already. As the journey progresses, you'll run into "stalls" or "plateaus" where you won't see progress on the scale. In those situations, many of us start to see progress with the tape measure. So as long as one of these numbers is decreasing, you're on track.
