Hi all,

Long time lurker, first time poster! This is a fantastic source of information and has eased my mind many, many times.

I was diagnosed with T2 around 7 weeks ago after an unrelated blood test showed high sugars and lipids. I had another blood test a week later to confirm and was called by the out of hours GP at 9pm telling me to go to A&E as my lipids were incredibly high (so high that he'd never actually seen them at that level, which of course eased my mind no end..). Long story short, three days in hospital and diagnosed with T2. Leave hospital on insulin, metformin, fenofibrate and a statin (latter two for the lipids).

I was home on the Monday evening and started the Newcastle Diet on the Wednesday morning, that was 43 days ago. Since then my weight has decreased from 92.5kg to 79.7kg, I came off insulin on day 10 of the diet (after gradually reducing), and reduced my metformin from 1000mg (slow release, 500 morning and evening) to 500 to 0 on days 14 and 16 respectively.

My BS in the morning has averaged 4.6 in the last two weeks (data is below if anyone wants to see all my numbers). My highest number in that time was 6.1, at 1hr postprandial. My diet consists of 800 calories a day from meat/fish and non-starchy vegetables, with a very small amount of dairy. Carbs are less than 30g a day. I run four times a week and usually walk an hour or so most days.

Finally I get round to my point! Sorry for the long winded post - I thought it might help if I give a bit of a background.

I decided to try an Oral Glucose Tolerance Test at home - 400ml of Original Lucozade (around 70g carbohydrate) after a 14 hour fast. I'd like your opinions on my results please (below). I did not carb-load before the OGTT.

Please note that the 'Adjusted mmol' figure is the meter reading minus 0.55 (or 10 mg/dl) for any numbers over 7.8 / 140 (source - http://www.phlaunt.com/diabetes/14046889.php). I don't know whether this was the correct method to adjust for the low carb diet. I'm expecting it's not, but I thought I'd add it anyway.

I tested every 20 minutes and obviously the spike is quite high at 13.1, though I was back down to 6.2 at 2 hours. However obviously I'm quite concerned about the massive 13.1, and it'd be great if I could get some peace of mind! I appreciate I've still another two weeks to go on the diet, and I know that capillary BS readings can be higher than venous, and also there's always a potential degree of error in the machines themselves. Perhaps after the diet I should try eating a higher carb diet for 3 days and then have another test?

Please see below for my numbers and charts (OGTT, fasting bloods, and daily BS readings).

I really appreciate all that you posters do, you help many many people that often can't get the information they need from their medical professionals. Thank you very much in advance for any replies.

Please note that I've slowed down with the amount of times I test as it no longer seems necessary....and my fingers hurt!

Hi, welcome and WELL DONE!

Those are some very impressive results. :D

My suggestion would be to wait for the end of your 8 week diet, and then gently 'carb up' for several days, to get your pancreas back into the habit of producing insulin.
Then do another glucose tolerance test.

Low carbers (and 800 cals a day is auto-low carb, plus you have been on 30 g carbs, haven't you?) are very likely to fail a GTT because their pancreas gets out of the habit of producing insulin, if it doesn't need to. I think it is called 'the last meal effect'. Only the lower carb you go, the longer it takes for the pancreas to wake up. With me, it is at least a week. But they generally advise carbing up for 3 days or so.

I know you passed the test you did, but if you do as I just suggested, you may find that 13+ spike is reduced, which will set your mind at rest. I hope.

Hope that helps. :)

And did I mention WELL DONE!!! :D
 
Very well done! An inspiration to us all. I haven't had the nerve to do the 800 carb diet yet - that's on my to do list. I've done the 5:2 before but that was before T2 diagnosis 10 weeks ago.

amazing results I would say you are cured... if you don´t gain all weight back which 166 of 167 persons do in a 10 year perspective... if eating almost like before...

it seems to me that his pancreas is already producing enough insuline as it got his blood glucose down in only 2 hours...

But his pancreas was slow to respond - or rather, if it was habitually producing standard amounts of insulin, then it would have been faster to respond.
