"I'm worried you're better now!"

When I got on carnivore diet 5 years ago and lost weight, tho I felt great and all my symptoms were gone. This friend kept raising one eye brow and saying "are you okay? You might have cancer!" 
It didn't matter how much I told her I'm better and healthier, she still kept saying "this is healthy?!"  

 Eat only industrial garbage, don’t do any sport, spend entire days in your couch and be morbidly obese and no one will ever say to you “you might get cancer” 

 Right?!
