my niece is now a very adventurous eater but when she was 5 we would ask her to try something like squash and she would immediately say no followed by an excuse like "what if it tastes bad and i cry" or whatever but it was always an adamant no...every ham has the same question "how can i lose weight" but when you give them the answer their immediate notion is to think of an excuse, any excuse, even if by no means does it resonate with any form of logic, hey cindy if you want to lose weight, try eating that salad without the 2 ladles of ranch dressing "oh no like my saliva cant process the acidity of letteuce so my doctor told me i should drown it in ranch and plus its already a salad i dont need to make it more healthy do i?"  you can show them proof that healthy does not equate to expensive but in their mind their mind is already made up and they are not actually listening to what you are saying, they are tooo busy processing a good enough excuse...
