Needing advice

Samantha

My son is 4 years old he’s over weight by 10 pounds is what is doctor told me. He doesn’t wanna eat heathy foods like fruits vegetables things like that he will not touch it or even eat it. I stopped buying ice cream because that’s what he likes to eat junk foods. I even mentioned to my parents no more Ice cream until I get his weight under control they seem to not care as much as I do I am just looking for some tips on how to make him want to eat heathy instead of wanting junk all the time and how to make my parents understand his weigh is very important at a young age.
