Sounds very healthy to me
Calorie count Depends on portion sizes
Breakfast - oatsosimple porridge (the strawberry one)
This is some kind of packaged product? they are tiny, so low cal, 80 kcal
with skimmed milk
presume that's like half a cup, not half a litre, 50 kcal
followed by a bacon and egg - both fried in a little oil - sandwich on wholemeal bread, no sauce or butter
Sarnie sounds like 600 kcal
Dinner -grilled chicken breast
how big?!! Oh well, assume it's not huge, 200 kcal
loads of spinach. Homemade salad consisting of tomatoes, onions, peppers, celery, sweetcorn, beetroot and cucumber.... lemon juice
almost no calories there
Mixed in with some natural yoghurt
Assume that's like one big spoon-full of low fat yogurt? then maybe 80 kcal
Snacks - a banana
100 kcal?
a packet of quavers
100 kcal?
a fudge
Like this size? that's 100 kcal
I get to total about 1410, pretty close to OP's guess.
I'd be still very hungry on that, so counts as low calorie in my world. Adult DD eats no more than 1500/day, so might think it's buckets
