You don't have to have dairy or meat if you're low carbing!
Keto is a particularly strict/restrictive way of eating, as it's less than 20g carbs per day. More general low carbing will allow you to eat more, which means more veg/salad (and some nuts/seeds/fruit)
A typical day for me (not sure if @MorePotatoSalad was asking me or you, @ImaHogg!) is:
Breakfast - just coffee; I fast till lunch time. If I am hungry, I usually have some yoghurt, with a little vanilla bean extract and/or peanut butter added to it.
Lunch - often eggs - a couple of boiled eggs, or hard-boiled eggs mashed with butter and/or mayo, a cheese or mushroom omelette. Sometimes full fat natural Greek yoghurt. Sometimes a sandwich/roll made using these products . They have been a revelation as they are genuinely low carb but exactly like 'proper' bread.
Dinner - anything and everything, as long as it doesn't feature pasta, rice, bread, potatoes or sugar! Last night I made a chicken and chorizo stew, using onions, garlic, black olives, capers and a tin of tomatoes. We had that with a celeriac dauphinoise and griddled asparagus.
Tuesday we had chilli, made with beef mince, smoky streaky bacon, onion, celery, chilli, mushrooms, kidney beans and a tin of tomatoes. Served with a dollop of yoghurt on the top and lots of grated cheese. DH had rice, I had mine on Bare Naked Noodles, which are only 1g carbs per 100g
On Monday we had roast pork, with mashed swede and buttered leeks.
Friday evenings we have a takeaway - usually curry. I relax things a bit for this. I don't have rice or poppadoms, but my usual main is chicken vindaloo, which always had a couple of pieces of potato in it. I nick a bit of DH's naan bread (just a corner!) and have a side of spinach or mushroom or cauliflower.
