is this diet a good one?

i am 15 and i am not overweight but recently i have been leading an unhealthy lifestylediet which was putting me at risk of becoming overweight if i carried on..

so i have tried to adopt a healthier lifestyle

i am 5ft 4 and weight 54kg

i wasnt that active today as i have been revising for an exam all day except 2 and a half hours running around in the snow and sledging and walking...

i ate

oatmeal: 30g oats,100ml milk,150ml water,one teaspoon of brown sugar,cinnamon,ginger and 4 blackberries. (200cal)

1 belvita biscuit: healthy biscuit containing oats and wholegrain (50 cal)

cup of tea: normal black tea with a little milk, no sugar.

one slice of brown toast with one portion of baked beans

banana

satsuma

plum

half an apple

2 strawberries

bowl of peas

very small amount of noodle soup (containing water,kidneybeans,chickpeas,lentils,noodles,and a load of herbs) like the amount you could hold if you cupped your two hands together

is this too little or too much?

is it balanced?
