I'm slim. It's a lot of genetic luck. However:
I am tee-total (not difficult for me as I don't like it).
I try to avoid UPFs now but haven't always. There was a time when I was extremely busy and out nearly every evening. My diet was really monotonous but still pretty healthy and was mostly batch cooked:
- Bolognase (with lots of veg, not just mince)
- Curry (veg, chicken, chickpeas with tinned tomatoes and spices)
- Chicken tonight sauce on chicken and veg
- Sausage casserole (basically sausage, veg, and tinned tomatoes)
- Stir fry and noodles
- pesto pasta
- chilli con carne
Basically all these meals are the same! All just chopped veg depending on what I had in the house, some kind of meat/fish or chickpeas, tinned tomatoes/sauce of some kind, cooked on the hob for 20 mins and eaten with rice/pasta/potatoes.
Lunch was always homemade sandwich (wholemeal bread but not homemade), choc biscuit, banana or other fruit, carrot sticks.
Breakfast was always toast and banana. I make my own granola now which is really easy.
I'm really busy so rarely snack.
I cycle a lot. I don't enjoy it, but I do it to get from A to B so it's like doing exercise by stealth. I also have a sport I enjoy for its own sake and do once a week. I hate the gym, I'd never exercise if I had to go to the gym.
