No one can appreciate the hard work you put into getting to where you are now but yourself. It's true, he tries to help out, he's supportive, etc but he'll never understand what you are going through: The food that you love, crave but have to skip, the hours you spend exercising, the blood sweat and tears.. they'll never know unless they've been there.
I have had the same reaction to fried foods specially that I've cut them out totally from my diet. It serves to remind me that I should think twice before indulging..
Its impressive much you've lost, keep it up
