Yea i have the same problem with my grandmom. When i visit her like every other week in the summer she always bakes the bests treats and she thinks im sick when i don't eat plus there are like 3 ice cream shops near her house so she takes me to get ice cream everyday too. but what i did was i told her that i was trying to lose a little weight and that i lovedher food but that it wasnt good for my diet and now she doesnt make as much sweets for me and when she does she doesnt force me to eat them. Good Luck
