Would this diet be healthy?

ok im 15 and wanted to go on a small diet, in the mornings i drink either a gl of brewed green tea or a bottle of water with either and apple or an orange. at lunchtime in school i have a bottle of water with an orange usually(or some other fruit). when i get home i usually eat a bowl of the maruchan ramen(i know not that healthy but i like it alot)with a bottle of water or green tea. then i eat whatever my mom makes for dinner with water or green tea. so i am just wondering if that diet is good at or if i need to change it at all.
