You CAN make soup without onions. I don't get on well with onions or garlic (IBs -ish) but make a great chicken stock from simmering the carcass for 6 hrs, with a carrot, parsnip and celery.
I make a soup with the chicken stock, carrots, red lentils and sweet potato. All whizzed up in the blender.
I'm roughly the same weight as in my 20s - under 8st (am now 62 and told I look 10 yrs younger at least.)
Breakfast - eggs- boiled, scrambled, poached, - and 1 slice gluten free bread.
Snack mid morning sometimes - an oatcake with almond butter.
Lunch- either homemade soup, or a salad with small tin tuna, or tinned salmon, lots of watercress, grated carrot, red pepper, and a small avocado .
OR I might have Greek yoghurt and an apple / blueberries.
Dinner- always a big chunk of protein- eg salmon fillet, chicken (stir fry, oven baked...) , fresh fish oven baked with roast veg (peppers, sweet potatoes etc), chicken roast dinner, homemade shepherds pie (I use venison mince which is lower in fat), stuffed peppers (I use a mix of Puy lentils, herbs and mushrooms), loads of veg and always broccoli/ cabbage, green beans, carrots etc daily.
Apple, blueberries, other fruit in season.
Everyday I eat:
some nuts- walnuts or almonds
a small avocado
full fat Greek yoghurt
eggs
at least 6 veg & fruit (combined)
Treat is 2 small pieces dark choc.
