To be honest, pax do not like larger looking cabin crew!
Since when? Most don't care providing theyre fed, watered and feel safe and warm, etc....
I worked as cabin crew when I was a size 18 and the feedback and letters sent to my employer were very complimentary. I had colleagues at the time who were larger and not once did any of them suggest pax thought any less of them.
You would have issues for a poisition on the deck though as a class one medical checks weight to determine your BMI and general helath for heart risk, etc.
When I had my class one for flying, I'd just gone from the overweight category to healthy weight category.
