Hey PurpleK,
It's not all that bad.
your BS are in a good place. Metformin has some great heath benefits log term and a few niggles (can be bad for some though)
My Hba1c is 5.2 and I have 2 x 500 metformin.
Forget the weight for now and focus on the cholesterol. This is not a simple topic, however it is made more complicated than it needs to be.
If you could stop processed foods for 1 month: butter, spread, sauces of any kind, pastry goods, baked produce, cows milk, egg yokes, processed meats or anything in a tin, except tuna - beans. Cook with vegetable ghee, coconut oil or olive oil, but even better steam, boil or gill where you can. Bin any salt.
Fish is a great place to start (no pun intended) if you don't like fish then stick to the veg and brown rice, seeds and nuts (you'll know about the high kal's in nuts).
My day could be:
1 grape fruit (An amazing healthy food with lost of benefits; BUT remember once you are on the pills this is right of limits for good, so make it work for you now, it can do the same job for your BP & Cholesterol naturally)
1 Fillet of smoke mackerel (High in good oils & protein BUT very high in salt; I won't be using salt any where else todays so it no worries)
Snacks for the day include a FEW nuts, berry's, seeds, tomato's (Different types), carrots, marmite on A (1) cracker bread, raw ginger, spring onions, avocado pear, raw peeled beats. Tomato's are great low kal's good nutrients high water content. I can do 20 over the day sometimes, NO added salt. You will quickly find the taste buds step up a gear making thing just that bit tastier too.
Lunch is £2 of fresh is best salmon grilled on a bed of raw spinach, sliced toms, picked beats (I've make my own) raw chopped mushrooms (so many mushroom choices) and an poached egg on top. Pepper it up, some lime & lemon juice and a douse of cider vinegar, if you can catch the oil from the grilled salmon add that to.
Supper is a homemade fish and vegetable curry with brown rice (limit the rice 1/2 mug pre cooked) and a crispy side salad. A curry is a great way to use all those bits that wont work together in a traditional meal, but are going to be in the bin over the next couple of days. I add almost everything and on a good day I can munch my way through 2/3 of the cooking wok. There is no real quantity here because it adds up to a vast amount of fibre and water, so fill your boots. Check out the amazing benefits of the herbs and spices used in curries, turmeric, cumin, fenugreek, ginger, chilli, etc. I have this most nights now as no 2 have ever been the same hot, cold or Thai. My tolerance for the hot stuff has increased which has increased my water intake as much as 3-4 pint during the meal, which in turn has produced a habit of drinking pints of water during every meal.
Now I know I mentioned egg yokes and then had a whole egg with my lunch, that is because the first step is to reduce your over all cholesterol as much as you can this includes some of the good stuff like egg yolks, in my case I have used a lot of oil fish.
After your months probation or even better after your next health check if your results are good you can start to add some more selection back into you diet. But I recon if the results are good which I am very sure they could be you'll be happy to make the changes for good and enjoy that full English one a fortnight.
As a bi product of sorting your cholesterol out, your weight will also fall and you BP will drop both because of your weight and all the good blood freeing, vein expanding food you are eating I'm not telling you what to eat here, it's only some food for thought.
WHY!
I was hba1c 11.5 / Chol 6.4 - Ratio ?/ BP 140/90 / Stone 14.9
3 Months hba1c 5.2 / Chol 2.52 Raito 2:1 / BP 112/70 / stone 12.5 (The weight drop was in the 1st 4-5 weeks)
I also ran for a while which got me into thinking about two points:
1) If a 5 miles run was burning off 300kals and a take away came to 1200kals at best, I'd need to run 4 times further just to stand still. So I decided to find foods closer to what I could reasonable burn off. A rice cracked @ 28kals would be lost by walking to the shop or parking a bit further away from my destination. Do this enough to get a negative value (I.e.. you would have to walk back again) and have a treat, make it a good one and enjoy it.
2) Food has become something different from where it started. By this I mean, It is.... No! it should be a nutritional packed fuel. The fundamentals of this involve no real pleasure as far as the mechanics are concerned. That is not to say that the pleasures of food should cause our spiritual wellbeing to suffer, but this is a different hunger (Oh I'm getting deep). Would you put old engine oil into you cars fuel tank and expect it to get you anywhere reliably and when it broke down would we blame ourselves knowing what we put in it, YES we would; but for some reason apply this to us and what we consume and there seems to be a different immediate answer. Why...in short I believe it is ignorance and for the same reason if you said No to the previous statement that would also be a total lack of understanding of your car.
It is a culture thing for sure, but I also feel we are being suckered for profits all the way to the bank.
I hope that this maybe help full or hopeful and is in no way meant to offend. Good luck PurpleK
Feel soo upset and frustrated right now
