What i ate today, is it good enough?

it is 3 o'clock

so far i have eaten-

breakfast:

a bowl of low-sugar alpen meusli mixed with a little special k berries cereal (i had a handful left of the special k and wanted to use it up) with skimmed milk

wholegrain toast spreaded with a healthy low-fat butter

one digestive biscuit

blackberry sorbet: handful of blackberries mixed with 125g of petitfilous (childrens fruit flavour yoghurt, basically 100g= one serving) and ice

one carrot

one satsuma

100ml apple juice

have i eaten too much or too little? im not on a diet i am 15 and a healthy weight for my height and age but recently i have had a poor diet which if i had continued with would have left me overweight, so im just trying to lead a healthier lifestyle :)

im going to have dinner with my family at around 5:30-6 which will porbably consist of one portion of meat, two portions of carbs and two portions of veg.. something around 400-500 calories like a big bowl of noodles with 4 dfferent types of veg and lean chicken breast cooked in olive oil or something..

should i eat more? less? dinner? no dinner?

haha

thanks for all your help everyone
