How to stay skinny and healthy?

My hieght is 5'2 and weigh 109 lbs I want to stay skinny cause I really like it.

this is what's in my diet, in the morning I have some eggs with brown bread, then for lunch I have chicken and rice with some juice and for dinner I have a glass of milk. And I'm also taking vitamins and eating nuts inbetween too and also add fruits too.
