Hi & welcome!
Don't fret about speed or just losing 1lb (or heck, even gaining a couple some week inexplicably while still on program- it happens!)
I never really had "the stall" but like many, I lost a pound or several, had weeks where I gained one or two.. best advice, stay on track (whatever that means for you personally) and DO NOT let your body fluctuations in weight trip you up from keeping on track. I stair-stepped my weight loss all the way down.. it's normal!
I too can eat anything, nothing has really bothered me, save for a few run-ins with OD'ing on sugar (at a yr + out from surgery, oh & poorly chewed raw veggies once).. Keep an eye on your behavior, and the effect it can have.. and make changes sooner than later if you see things heading the wrong way.. The VSG is a wonderful helping hand, but the further out you get the more you need to stand on the habits you put in place while you were healing! Good luck!
