Ds is 16 and definitely still growing (for reference is currently 5'9" but with a 28" waist and 34" inside leg, his upper body has not caught up yet 😂)
Breakfast: on weekdays weetabix or porridge with a banana, Saturdays he usually has toast if anything at all and on Sundays I usually do a brunch/cooked breakfast of scrambled eggs, mushrooms, tomatoes and a couple of hash browns
Lunch: he takes a packed lunch to college and has a chicken sandwich, 2 portions of fruit, a couple of Babybels and a small malt loaf. Once a week on a Friday he goes to Taco Bell with his friend for lunch and has a burrito or quesadillas instead
Dinner: usually pretty balanced, I'm tracking my food to lose weight so it's usually healthy, lots of lean protein, good carbs and a couple of portions of veg
Snacks: yoghurt, all the fruit (I spend a small fortune on fruit but rather this than junk food even if it is a lot of sugar), he'll have a biscuit bar or a couple of plain biscuits in the evening too
We only eat desserts once a week on a Sunday unless we eat out and it's a small pot of chocolate pudding or similar. Since having his fixed braces fitted, he only drinks milk, water or sugar free cordial and has one glass of Pepsi Max a week (through a straw because of the braces)
I think it could be better but is fairly balanced, he gets a decent amount of exercise and has always been slim and full of energy, 10 year old dd is another matter, she'd live on chocolate and pizza if we let her
