Eat only UK Plants/ Rationing

I'm going to start the WW 2 Rations Diet - on Monday, giving me the weekend to get my rations in.
Bread, potatoes, UK grown fruit & veg and fish were off-ration most of the time and they're the mainstays of my diet anyway. 
If you're interested, there was a weekly ration and a Points system that you could use to choose extras every 4 weeks. Sometimes the amounts changed according to whether there were supplies available but this list is an average one!
Weekly ration -
Bacon & Ham 4oz
Meat about  £2.50 worth in present day money
Butter 2oz
Cheese 1 oz
Marg 4oz
Cooking fat 2oz
Milk 3 pints
Sugar 8 oz
Preserves 1lb every 4 weeks
Tea 2 oz
Egg 1
Sweets 8oz every 4 weeks

You could give up your meat ration and swap it for an extra 3 oz of cheese and an extra egg, which I'll be doing.
On top of that you had 16 Points every 4 weeks which could be used to buy a pound or a tin of the following:-
Baked beans 2 points
Dry biscuits 2 points
Sweet biscuits 4 pts
Herrings 2 pts
Lentils or split peas 2pts
Rice 8 pts
Sardines 2 pts
Sultanas 8pts
Currants 16 pts
Skimmed Milk 5 pts (not sure how much?)
Rolled Oats 2 pts
Salmon 16 pts

I'll be spending some of my Points on Lentils & Split peas, Oats & sardines. Also converting the weekly amounts to 4 weekly as its easier to buy a pack of butter or block of cheese that buying a  couple of ounces. I'll make each pack last 4 weeks and if I run out, go without. 
A slight bend of the  rules - if I pick up any free food it doesn't count - it'll be the undercounter food that the grocer kept for his special customers.
