However, type 2 diabetes is clearly reversible following
bariatric surgery . The normalisation of plasma glucose
oncentration follows within days of surgery, long before
major weight loss has occurred, and it has become widely
assumed that the protective effects of gastrointestinal
surgery are mediated by altered secretion of incretin
hormones [8, 9]. Improved control of blood glucose in
type 2 diabetes by moderate energy restriction has been
demonstrated by others [10]. We have hypothesised that the
profound effect of a sudden negative energy balance on the
metabolism could explain the post-bariatric surgery effect
[11] and, specifically, that the decrease in the intracellular
fatty acid concentrations in the liver would lead to a lower
export of lipoprotein triacylglycerol to the pancreas, with
the release of beta cells from the chronic inhibitory effects
of excess fatty acid exposure.
This study was designed to test the hypothesis that acute
negative energy balance alone reverses type 2 diabetes by
normalising both beta cell function and insulin sensitivity.
Problem is, Bowell, they didn't follow the test subjects long enough, in my opinion, to make the broad conclusions they're attempting. And the info shared on Bariatric surgery patients is often 'short term' too. We need need more 'long term' studies. Like what happens to bariatric surg patients 3 years out?? After they return to eating higher carb foods - albeit smaller amounts for sure. There is virtually no research showing that angle yet. And right after Bariatric surgery -OF COURSE people's 'hyperglycemic symptoms' go away -- as they're eating virtually 'nothing'. If I were to eat as little as a post op bariatric surgery patient - my numbers would be near perfect too. There are too many 'holes' in this research method to be of any real value to us -- yet. I'm disappointed in this study - though intrigued.bowell said:NewdestinyX
You say was a small study and you are right
However This study. to try and copy and understand what was already happening with weight loss surgery and T2 reversal reported . Low cal liquid diet before and after weight loss Operation wile the patient recovered.
if this is whats really going on then the numbers inc the bariatric surgery T2 patients
are a lot higher ?
if you could achieve all this from off the shelf diet Wow!!!!
It's Only about 4oz of food per meal. I doubt that could spike anyone's sugar no matter what the carb ingested. I could be wrong though. But the severe calorie restriction IS in the equation of the dispelling of the hyperglycemia.viviennem said:Is it possible to find out how many carbs are included in the pre- and post- bariatric surgery diets?
Going by the couple of people who I know have had that op., the diet they were on until they committed to the surgery was extremely high in carbs, of the bread/chips/pastry/pizza/burger/cake/biscuits/crisps variety.
Could the observed reduction in blood glucose levels be as simple as severely reducing their carb intake?

Yes, great point. No matter how you look at - we're talking about a starvation diet here -- for an adult that is. But I'm still SO intrigued by the elimination of the fat around the organs that this diet produces. That has to be 'good' - even though the methodology is harsh to say the least...catherinecherub said:An article here, commenting on the "cure", suggests that 600 calories are the requirements of a 4month old baby and recommends a diet of 1200 - 1800 for losing weight and putting diabetes into remission.

Oh PLEASE report back as soon as you get your answer. And lots of details. I can't wait to hear what a couple of docs say about this 'new find'.Marzeater said:Just seen my GP about this to ask his advice before going ahead with it.
He has told me not to do it yet, and has written to a specialist to ask his opinion. A further appointment has been made to discuss it further in 3 weeks by which time he should have a response.
GP said i'm the first to raise this with him but wont be the last.

Irish Hunger Strike of 1981
In 1981, members of the Irish Republican Army (IRA) imprisoned in England went on a hunger strike to protest their incarceration. Former IRA commanding officer Bobby Sands was actually elected into the British House of Commons while striking, helping to raise awareness for their cause.
Prime Minister Margaret Thatcher refused to bend, however. The prisoners drank small amounts of water, but refused food altogether. Sands died from starvation in a prison hospital on the 66th day of the strike. Thatcher remained steadfast and called Sands a criminal and his death a suicide. Nine more prisoners died from starvation after Sands. Thomas McElwee lasted the longest, at 73 total days -- a full week longer than the next closest prisoner

What you state there, CMichael is an important caveat. It's just that before this study ANY REVERSAL of ANY KIND has never been seen. In this study - the 'non return' of the fat around the liver and pancreas and the steadyness of the HBA1c even after weight gain happened is 'new'. I also understand the 'sociological' implications here if this study is on the money at all.. But I'm not 100% sure IF or NOT It 'reintroduces' the unpopular idea that 'behavior', in particular eating habits, is IN the question of the onset of T2. I know there's probably a couple hundred threads here about that... so I won't start up again.. :roll:CMichael said:One point that hasn't been covered much on this topic is the effect on beta cells. Maybe losing fat in and around the pancreas and liver helps to preserve the function of beta cells but surely it can't reverse the process of beta cell loss, which is what makes diabetes 'progressive' - even if that progression may be very slow? And this particular trial was with people who had relatively recently been diagnosed with type 2. It's a very interesting area to research in future but I think the researchers were a bit quick to claim a 'reversal' when there are still so many unknowns, sadly.
Good challenge, CMichael. I should have been more precise to say 'ANY REVERSAL' of the type this study noted (fat deposits on organs - HBA1c steady even after weight gain, etc). By adding the 'ANY KIND' I overstated and thereby confused. Let me 'rein in' those types of statements and be more precise. Thanks for the challenge!CMichael said:'It's just that before this study ANY REVERSAL of ANY KIND has never been seen.

I'm not quite sure what you mean by this NewdestinyX? There are lots of people on this forum and elsewhere who are controlling their HbA1c at normal levels by diet and exercise? Which is as much of a reversal as seems to have been achieved here? They aren't having the fat around their organs measured in the detail this study went into, so we can't know whether theirs disappeared and stayed off too. Perhaps that is the research that needs to be done next - looking much more closely at the metabolic processes of people who have lost weight through less drastic means and have kept it off for longer than this short-term study.
