Healthy Diet Routine? Yes, No, Maby?

[KB24]

I don't so much want to lose weight as I want to get healthier (and maby lose a few pounds). This is the routine I've done the past 2 days and seem to like

breakfast:
-bowl of cereal (wheaties, low sugar fruitloops, honey bunches of oats)

-bagal with cream cheese
-sandwhich with meat and cheese
-soft pretzel with cheese

dinner:
something with meat (2 helpings of)

desert:
usually a 100 caloire ice cream bar (sometimes more stuff if im hungry)

--is this a good daily diet. Does it include all the nutrients and vitimains i need. If i am pretty active will i lose weight eventually? thanks
