Size 10, 5'10", late 40s.
Breakfast good grainy/sourdough toast with avocado. Sometimes feta or Cheddar too, or salmon paté. Two black French press coffees, no sugar.
Mid-morning is terrible 
tea with oat milk (not sweetened). Handful of crisps and something like a biscuit or half a slice of cake. If I'm having a 'must eat less shite' phase I'll have a banana and/or apple or small orange instead, maybe a few fancy crackers (sourdough or spelt) with more advo and/or cheese, or plain unsugary granola with plain sheep yoghurt and some soft fruit.
Lunch is sometimes a curry and rice or bread from a lovely Indian place; sometimes a sourdough chicken salad sandwich; sometimes tuna mayo sandwich or tuna melt from Pret.
Mid-afternoon a repeat of a variation on the tea/crisps/biscuit/cake/crackers/granola/fruit thing.
Dinner is usually veggie or vegan, although I'm not prescriptively either: I make a range of veggie curries, and eat them with brown rice or naan or both, sheep yoghurt and pickles/chutneys.
Or simple pastas: puttanesca or courgette with olive oil, cheese and lemon, that sort of thing. Usually with some buttered toast.
Stews, usually made with vegetables and pulses, occasionally chicken or fish.
Occasional takeaway: Asian or pizza most frequently.
Usually have herbal tea after dinner (rock n roll, I know) and sometimes a few squares of dark or nutty chocolate.
Do a fast and furious zumba class 2–3 times a week, an hour of ballet fitness most weeks, yoga sometimes, albeit not strenuous yoga.
I don't drink, and rarely eat red or processed meat, and I live in a city and don't drive, so walk anything from fifteen minutes to half an hour quite habitually. I think all of these have a big impact.
