There is an awful lot you can change there in addition to the excellent start you have made.
Two brown toast with 2 boiled eggs.
Scrap the 2 slices of brown toast. Go back to your fried breakfast, with 97% meat sausages, eggs, bacon, tomatoes, mushrooms. No bread.
Maybe half an apple. (apples need testing to make sure you are OK with them, if not, have raspberries or a few strawberries with full fat yogurt or cream. You can get low carb bread. Burgen is about 12 carbs per slice. Personally I use Hovis wholemeal seed sensations at 14 carbs per slice, but I can only manage one slice per meal with plenty of butter on. Many on this forum can't manage any bread at all.
6 crackers. Too many carbs. One or 2 may be OK, or replace with salad, tomatoes etc
Snack - stick to a few nuts or cheese. Not fruit unless it is a few berries.
Jacket potato with cheese.
Scrap the spud. Cheese is fine. Any meat or fish with veg is excellent
No lager - it is liquid sugar. Dry red or dry white wine and most spirits are OK (sugar free mixers)
Coffee is fine, but watch the milk. Try it with double cream instead.
It is carbs we have to watch as they all convert to glucose once in the system and it is glucose we do not want. The fewer the better, and potatoes, rice, pasta, bread, cereals and flour are the worst culprits. Jacket spuds and mash are very unwise. A couple of small new boiled or roast spuds might be OK but you would have to test to check your tolerance.
We can eat as much meat, eggs and fish as we like. Leafy green veg and salads are great. Toms and mushrooms perfect. Dairy produce except milk is excellent, but not the plastic low fat rubbish as it has too much vegetable oil and probably added sugar. Milk must be taken with care as it contains a lot of sugar.
Don't be afraid of dietary fat ..... it is good for you and good for blood sugar levels. If you cut the carbs and increase your fats you should lose weight if you get the balance of calories right.
