I'm late 40's, 56kg. Was 49kg before I had kids, so an increase, yes, but I think I'd look really sickly if I was that weight again now? At least, I'm sure my body would look fab, but my face would look about 90. I put on a couple of kg after lockdown, lost them again in a couple of months.
Don't have a car so walk everywhere. Hate gym/running though. I walk 5k - 10k steps a day, usually around 6k or 7k. Sedentary job, usually WFH or from nearby office.
A normal day for me is:
7am: cup of tea (milk/sugar), 1 slice of toast (homemade bread/jam/butter). Black coffee at some point.
10am: two big tablespoons of greek yoghurt with whatever berries or fruit we have, pumpkin seeds and a bit of jam or chopped chocolate
Lunch might be a small bowl of leftovers and some salad, or a couple of boiled eggs with butter and a slice of toast like just now. I always cook enough dinner for there to be leftovers for lunch.
Never hungry in the afternoon. Maybe a mandarin and a square of chocolate. Tea, obv.
7pm: Dinner will be just.. normal? spaghetti bolognese, chicken enchiladas, roast chicken etc. I vaguely watch the carb part and don't go overboard. I don't eat til I'm stuffed (unless it's roast chicken with yorkies etc. YUM). We don't do pudding but maybe a couple of squares of dark chocolate and an orange.
Glass (small) of wine later in the evening.
At the weekends, I might have a fancy hot chocolate or coffee and a piece of cake in a cafe in town.
On the whole, everything we eat is homemade with a bare minimum of processed food and no ready meals, ever. Probably quite high in fresh vegetables. No frozen food at all. I think it's mostly about moderation though. And if it's a "treat" food, like a posh croissant from the bakery or slice of cake, I will split it with my DH, or bring the other half home for the kids. I don't do this to deprive myself - it just feels like too much.
