I’m 5’1 and weigh about 7.5 stone. I can eat what I want and don’t put on weight, but I’ll caveat that by saying that it’s clearly genetic as my mum, sisters, aunt, cousins all have the same build and my dad was quite slender as well. I also have a smaller appetite than most people, and walk almost everywhere.
Typical day of food for me:
Breakfast: Cereal (mini wheats or similar) with milk
Morning snacks: Choc chip brioche, couple of biscuits
Lunch: Sandwiches (cheese and ham, ham and tomato, chicken etc) made with white bread
Afternoon snacks: Another brioche, apple or another piece of fruit, maybe a bar of chocolate if I need a boost at work
Dinner: Something like spaghetti bolognaise, stir fry, risotto, or something more basic like chips and sausages (once a week)
Evening snacks: a biscuit or a few pieces of chocolate
I don’t drink much - maybe one glass of wine in the evening at weekends.
But as I said, I think it’s genetics and having a smaller appetite compared other people. For example, if I had a big lunch, I wouldn’t cook a main meal for dinner as well - I’d do a sandwich or scrambled eggs or something, so my food intake would be the same as a normal day.
I’ll have a coffee and a few cups of tea during the day, but generally only drink water after that.
