Why big bellies could mean big trouble for brain function in later life
Posted on 28 March 2008
Previously on this site I have presented evidence that the traditional way of assessing body weight

Yes, wheat bellies. I’ve noticed my neighbor has developed a slight one in recent years. It isn’t from lack of exercise; he has a manual labor job and is gets a workout from his daily activities.
BUT, in recent years, his wife has implemented “healthy lifestyle”. They have reduced red meat to almost nil; reduced saturated fat from their diet and increased vegetable oils; and they have shifted to more “whole grain” flour products. Sigh.
He did a job for us and I cooked some local eggs in butter for him and I thought he was in heaven, after so many “Egg Beaters” and bran cereal bowls.
Now his doctor is suggesting a statin because his cholesterol profile has shifted negatively, despite the “healthy lifestyle”. He was open to a low carb way to deal with this, but his wife completely shut down the notion. Sad.

She’s not trying to kill him off with a high-carb diet is she? (That’s a joke, by the way…)

When I saw the “big belly” in the title I immediately thought of Homer Simpson!
So it’s not just the beer that leads to the big belly and also causes dementia!
And just a thought – if Homer ever got dementia, would anyone know the difference?

I have been Nursing ,Dementia’ patients for 28years now,
I have looked after many people in their own homes, at
present my patient has been suffering from ‘Dementia’ for
the past nine years, her GP told us she was in her last stages about two years ago, she is still here and smiling and talking,
I cannot see what having a ‘big belly’ has got to do with ‘dementia’ all the people I cared for were very slim.

The big belly usually means they are having a high sugar diet. Elderly people don’t usually have a belly – they may of when they were younger but as people age a lot of them lose weight and look frail – perhaps because they don’t seem to absorb the nutrients very well from foods they eat and they don’t eat very healthily, especially if they are in a nursing home and eating all that stodge and becoming protein deficient.

I think I read it on McCleary’s blog that in the brain you may get Type 3 diabetes – just like type 2 the brain becomes resistant to insulin causes all sorts of problems – dementia being one of them.

There are many factors involved here. I believe generally that people who do not take care of themselves(overweight) are also lacking exercise, proper nutrition, suffer from toxicity and potentially not dealing with stress properly. The weight issue is probably indicating the these factors.

Okay so how does one measure this belly thing? And what exactly is the midriff? Is this different to a waist measurement? I mean what exactly is meant by ‘the middle’? It’s not exactly a scientific term. I thought I was safer because I go in at the waist and my waist isn’t too big, but if the measurement is lower down…hmm…bad news. Perhaps this explains why I can’t do chemistry equations.
Women with PCOS/Stein-Leventhal syndrome often have short term memory loss. Is that connected?

That’s fair enough to find fault in the original study, but I recommend we do not lose sight of the fact that individuals with impaired glucose metabolism/diabetes have been shown to be at increased risk of cognitive decline, and there are known mechanisms that may explain these findings. And there is good reason, I believe, to be wary of the need to control blood sugar and insulin levels if we’re looking to reduce risk of mental decline/dementia.

I believe we’ll eventually find that increased intake of insulin-raising carbohydrates will be linked to many of the crippling “western” diseases we face regardless of whether the individual gets obese as a result. There are lots of thin people that have cholesterol problems. The fact that they don’t suffer from obesity seems to be unrelated to the onset of insulin-related problems later in life.
This study might be a result of the “low-hanging fruit” syndrome. Finding people with an increased incidence of dementia amongst the obese is not surprising. If someone could do a detailed study of lifetime carbohydrate consumption and its relationship to the onset of disease later in life, I believe we would see an association between high-carb eating patterns and dementia regardless of whether one also becomes obese.
In other words, the increasing incidence of dementia may not be related to obesity, but rather the per-capita increase in carbohydrate consumption in the western world in the last century or so. The fact that some fail to grow obese as a result of higher carbohydrate consumption doesn’t offer much protection from the other damaging effects of higher levels of insulin in the body chemistry, like heart disease, bad lipid profiles, etc. Plenty of slender folks suffer from those maladies as well.
I believe we

Steve, you’re absolutely right. Some may display obesity as a sign of excess insulin whereas others will remain slim.
March 30, 2008 @ 1:05 am
All three close friends and relatives who developed dementia were slim and physically fit. It doesn’t seem to make much sense, does it?

I bet if you looked at alot of these people they are eating tons of fat as well as carbs . It is far too simple to blame carbs – most of these people eat loads of crsps, fries, cake etc. plus excess alcohol!
Everyone on here just seems to blame carbs – which is clear nonsense.

The ideas here suggest that the factors involved in causing abdominal obesity are A potential cause of dementia, not THE cause. Plus, I suspect nothing will make much sense if you use (limited) anecdotal experience to trump wider evidence in the research.
Bob
What we have here is evidence linking abdominal obesity with increased risk of dementia and some plausible explanations for common underlying factors (i.e. carbohydrate and insulin excess).
If you have any evidence that, you believe, disproves these ideas or proves some other mechanism then please provide it. Please do refer to published research if you can.

dr Briffa – I guess you do not like comments on here unless they are science. I looked at your site for ideas about food and eating as you say you are a nutritionist but there is nothing on here at all apart from the usual carb bashing I see on other low carb nessage boards. No practical advice what so ever.
Surely it is common sense to not eat excess fat – apart from the fact that food with alot of fat is not that nice. you know all the fried stuff.
I am intriqued by your book someone lent it to me – who are you aiming it at – not people on a budget. The recipes are completely impractical and expensive – venison , t bones – I recently bought a t bone cost me

Pretty much all views are ‘welcome’ here, but it does help if comments are well argued and/or science-based. Yours, in my view, are neither. So please don’t be too surprised or upset if you don’t get a completely free ride here.

you havent commented on the book .
You say in your intro you cut thro the hype but there is no practical info on here at all – any comments.
So basically you only want evidence is that what you are saying.

What has the practical advice I offer (by the way, there’s plenty of food and meal suggestions and recipes in the book) got to do with ‘cutting through the hype’? (answer: nothing).
No, it’s not only evidence I want, necessarily. Something, well argued (as I said before) and intelligent would be a good start. As usual, you’ve failed to provide anything remotely cogent.
If you want me to post your comments and take them seriously in the future, I think you’re going to need to step up your game a little (a lot, actually).

Fat and carbs in combination and eaten to excess is a recipe for weight gain. Most of the foods mentioned above would be full of unhealthy fats like trans-fats not the beneficial saturated fat. Carbs are targetted because they are a big problem for people who want to lose weight and are insulin resistant. When they go on a lower carb diet they lose weight. If you can eat more carbs and remain lean then good for you alot of people cannot.
Another thing, just because someone is lean doesn’t mean they are healthy, they may be able to remain lean whilst eating a tonne of carbs but being lean doesn’t exclude you from getting a disease.
Our bodies need fat and protein but do not require carbs.
