weight loss stall.. help

Over the past few months I've gained :sad: decided it was time to get it back together! I lost 5lbs this week but towards the end of the week my weight loss stalled. I am so bummed! I follow the 17 day diet and I have celiac disease, I know I don't exercise like I should. My job requires me to be on my feet at least 6-8 hours per day which leaves me exhausted. Anyone have any suggestions to get it going again?
