most people see the biggest drops during the first month or two after surgery. After that, it does slow down to about 2-3 lbs a week (maybe a bit higher for those with a higher starting BMI). So your rate of loss is pretty normal. I'm not sure where you started, but I was well over 300 lbs. I lost 16 lbs the first month, and then 10-12 lbs a month for the next six months or so. Then it dropped down to about 6-8 lbs a month....and gradually went down from there (by the end, it was like two lbs a month - UGH!). As long as you're trending down, you're good!
and to reiterate, yes, your rate of loss is completely normal. Just follow your plan. If you cut back too much from your plan, you risk getting sick or having deficiencies. So I would not worry about "moving the needle faster". Massive weight loss is a marathon, not a sprint, as they say...
