Low budget is certainly a problem - I have to be careful, but not as low as you, and food is my main expense once bills are paid and a tank of fuel put in the car! Clothes come a poor 4th - good job I'm scruffy by nature! :lol:
The diet you call your ideal would suit me too - except too many nuts for me (I have no willpower and if they're in the house . . .!), and too much fruit. I don't even eat fruit every week.
Can you eat salad-y things once they are in season and cheaper? Or is there any chance you can grow any, even in big tubs? Root veg tend to be highest in carbs and above-ground lowest, with the obvious exception of eg sweet corn. Sweet potatoes aren't too bad, nor are lentils or chickpeas in small portions. I follow the Atkins list; I avoid peas and beans, but eat green beans; mostly I live on them with broccoli, cauliflower, leeks, courgettes and mushrooms. Occasionally I'll have a carrot.
I've had a vegetable stew 4 times this week- 1 large carrot, 1 onion, a fennel bulb, a stick of celery, a sweet potato (left over from Christmas :shock: - still okay), 1 tin tomatoes, 1 red pepper, 1 orange pepper, lots of mushrooms, 3 garlic cloves, pepper, mixed herbs and mixed spice. It's the sort of thing I might put red lentils in, too. Instead I oven-cooked 6 low-carb sausages at the same time and then bunged them in. It tasted quite sweet from the potato and the peppers, and was delicious!
If I buy a chicken I have it hot the first day, almost by itself sometimes; then I will make a 2-portion leek, courgette and mushroom casserole and have that twice, once with cold chicken and then with cold chicken mixed in to warm. By the time I've had a couple of salad lunches off it as well, it will have done me 5 or 6 meals. I buy big chickens!
. Then stock for soup. I also stock up with turkey legs at Christmas - they often go quite cheaply, now many people don't want a whole bird, just a crown. I've got one defrosting now.
Can you get rabbit? One butcher round here (I'm in the middle of the country) does jointed wild rabbit for £2.50. At least 4 portions, it makes cheap meals. Or I can get a whole one, naked and empty, for the price of some cartridges, they are such a pest. I'm lucky enough to live next to a gamekeeper, who gives me the odd game bird which has been too mangled to be sold. He skins them for me and just gives me the "crown" - the 2 breasts on the bone. If your butcher sells venison, there is a good cheap cut called venison flank, which casseroles brilliantly and is so healthy! Shin beef is great, cooked long and slow it's very tender and thick. Goes well cooked with onions and lentils, or with shallots.
Did your dietitian say anything about which fruits? Plums and apricots are best for low-carb and low GI, followed by any berries - all of which are too expensive at this time of year. Some tinned fruit is okay, provided it's in juice not syrup, and you have small portions. I go for apricots, peaches and pears in tins - but not often, and small portions. Avoid oranges, grapes and pineapple - or try them and test 2 hours after eating, as different people can tolerate different things. I can cope with a small apple, and I have to confess that I do sometimes have a banana - a child-size or "fun-size" one, as they call them in Tesco. I buy sugar-free jellies - they aren't expensive and eke out the fruit.
I would hate to be lactose intolerant, so you have my sympathy. Do let us know what sort of "dairy" you're eating - I like sheep and goat cheese and yoghurt, but I suppose they must contain lactose too?
Anyway, at least the dietitcian is paying attention to your problems, which must be a relief in itself. Let us know how you go on.
