7 weeks out, and still my weight hasn't changed that much.

When I was not happy with numbers I would make a list of NSVs. Don't compare yourself to others either. We all lose weight at different paces. 

Make sure to write down everything you eat. Healthy habits make it easier in the long run. 

This is a marathon not a sprint. 

One meal at a time. 

I haven't lost huge amounts of weight since my surgery - about 13 lbs per month.  Be patient and make sure you are drinking enough.

First, I am going to assume you aren't a revision.  Otherwise my comments aren't valid.

See, I think the first 6 months is a sprint and I think you are wise to have some concern.  I would suggest you post your food on the WAYE  thread for critique.   Ensure you are weighing and measuring.   High protein,  low carb and lots of water.

Agreed you should take your measurements weekly.

you may be doing everything perfectly and this is just how your body is going to behave.  But I repeat., smart to question and catch a problem right now while you are in your honeymoon period.

Good luck
