The cure for diabetes

url

I was recently informed that there is a cure for type 2 diabetes. Apparently researchers in Newcastle have found a way to reverse type 2 diabetes. According to their website:

Our work has shown that type 2 diabetes is not inevitably progressive and life-long. We have demonstrated that in people who have had type 2 diabetes for 4 years or less, major weight loss returns insulin secretion to normal.

Obviously, we dietitians have been recommending weight loss, diet, and lifestyle changes for many years. However, these changes rarely result in a complete reversal of the condition. The best case scenario is usually that the patient is able to manage their diabetes without the need for medications. More often though, it means that the progress of type 2 diabetes is slowed and less medication is needed to keep blood sugars reasonably stable. Despite this research having been conducted back in 2008 this was the first that I had heard of it.

For those interested, the complete study Reversal of type 2 diabetes: normalisation of beta cell function in association with decreased pancreas and liver triacylglycerol is available here. To summarize, they looked at eleven people whom had been diagnosed with type 2 diabetes within the previous four years. Yes, that’s correct, eleven people. That’s a pretty small sample size. That means that no matter how astounding the results, it’s impossible to say if they will be applicable to the majority of people with type 2 diabetes.

The results of the study were quite good. All of the participants saw dramatic improvements in both fasting blood sugar and plasma insulin levels after only one week. In fact, after only one week of the eight week program, these levels were indistinguishable from a non-diabetic control group. Because normalization of beta cell function and insulin levels were seen in the participants, they were deemed “cured” of type 2 diabetes upon completion of the study.

What exactly did the researchers do to “cure” these people? They placed them on strict 600 kcal a day diets. Now, I don’t know about you, but that number shocked me. 600 kcal a day is extremely low. Most medically supervised low-calorie liquid diets for obese patients still have them consuming 800 kcal a day. Most weight management programs recommend patients consume at least 1, 200 kcal a day. For most people, 600 kcal is one meal (for many people, it’s less than one meal). In this study, participants consumed 510 kcal worth of Optifast shakes per day and were encouraged to supplement with non-starchy vegetables and drink at least two litres of water (and other calorie-free beverages) each day.

Because there was no follow-up with participants upon completion of the eight week study, there is no way to know for certain if they were actually cured of their diabetes or if it returned after they completed the program. Even supposing the diet is a cure for type 2 diabetes I can’t help but wonder how many people would be able to adhere to 600 kcal a day for eight weeks. As with any medicine, it doesn’t do any good if patients won’t take it. I suspect that the majority of people would forego the cure of such a strict diet.

All issues with this being touted as a “cure” for type 2 diabetes aside, I would like to see further research in this area. Larger, longer studies would be interesting. I’d also like to see a variety of levels of caloric restriction used as well as different sources of nutrition (not just shakes).

Follow Friday: All of the low-carb diet blogs

url

When the news about the new “low-carb diet is the best long-term weight loss diet” came out I fleetingly considered writing about it. In the moment that I took to think about it, pretty much everyone else had covered it. So… Rather than reinvent the wheel. Here are some links to posts that say pretty much everything I would have said (and then some):

James Fell on Six Pack Abs: New Study: What is low carb good for

Karmal Patel on Examine.com: Is low-carb really the best weight loss diet?

Yoni Freedhoff on Weighty Matters: What I actually learned by reading that low-carb is best study

Julia Belluz on Vox: The one thing you need to know about weight loss and diet studies

There’s more, but that’s probably more than enough reading for now. I’m off to The Canteen for a sandwich. See you Monday!

No big fat surprise that butter is being touted as the next Superfood

url

Why, oh why must we take everything to the extreme? Is it because simple healthy eating is boring? We have to have “clean eating”, “superfoods”, “low-fat”, “low-carb”, “cleanses”, “high-protein”, yada yada. The latest mantra to irk me “slather on the butter”. I know, I know, I said it first “real dietitians eat butter”. But this doesn’t mean that we have to eat it to excess. What am I on about now? An article in the Daily Mail that I came across on the weekend: Can eating fatty meat, whole milk and lashings of butter help you LOSE weight?

Okay, most of us in the nutrition world have accepted that low-fat was a grievous error. Taking anything to the extreme is a nutritional error. Just because something is not “bad” for you, or even good for you, doesn’t mean that you should consume more of it. The logic seems to go: apples are delicious and nutritious; therefore, an entire bag of them must be even better. In this case, we’re not even referring to foods that we know to be healthy when consumed regularly. We’re referring to foods that were unfairly demonized but have not been shown to lead to good health when consumed daily.

Perhaps, the article in the Daily Mail does not accurately portray Nina Teicholz’s book The Big Fat Surprise. I haven’t read the book, so I can only comment on the news article. Encouraging people to eat more cream, high-fat red meat, butter, and other foods high in saturated fat is not the solution to the obesity epidemic that the Daily Mail would have you believe. Yes, you can lose weight eating anything; remember the Twinkie Doctor? This doesn’t mean that you’re healthier (especially in the long-term).

Apparently Teicholz claims that removing the fat from milk means adding more carbohydrates. No. When you remove fat, you are not adding anything. Yes, an equivalent quantity of skim milk will be higher in carbohydrate (not sugar though) than whole milk. That’s simply a result of what’s left behind when you remove the fat. It’s also higher in protein, minerals, and vitamins. We wrongly vilified saturated fat, let’s blame carbs.

Health and the battle against obesity should not be a nutrient blame-game. How about we stop demonizing and glorifying foods and nutrients and accept that there is a place for bread and a place for butter in a healthy diet.

Jennifer Aniston weight loss secret?

Is it just me, or are the facebook spam ads getting more insidious? As much as I loathe FB it does prove useful for blog fodder at times. Has anyone else seen this ad in their feed?

Note that the link at the top says “Shape.com”. Make you think that it’s an article in Shape Magazine, doesn’t it? Well, it’s not. If you take the bait, it brings you to Shape.com-11.tv… and an “article” about How to Lose 7 lbs of Stomach Fat EVERY Week with Just 2 Diet Tips. Jennifer Aniston uses this simple trick to melt fat off her legs! The website looks like a cheap reproduction of the true Shape website. If you didn’t know better, and didn’t check the URL, you might actually believe that you were reading an article in Shape.

However, the “article” is yet another thinly veiled advert for (have you guessed yet?) garcinia cambogia. It’s pretty much the same idea as the green coffee bean ads masquerading as news articles I’ve blogged about before. Is there any merit to the use of garcinia cambogia for weight loss? In a nutshell, nope. If you want more than a nutshell, I recommend this write-up by Gemma Critchley, a fellow dietitian in the UK.

The notion that Jennifer Aniston ever had 32.5 pounds to lose is pretty ludicrous in and of itself. I’m pretty sure that at any recent weight, if she were to lose 32.5 pounds she would be hospitalized. However, I can see how the allure of quick, easy weight loss paired with the notion of having a body worthy of celeb could make people want to believe in the validity of garcinia cambogia. Sorry guys, bad news. Jennifer Aniston has a body like that because it’s her job. She puts a LOT of time, money, and effort into being super slim. Instead of wasting money on expensive, useless supplements, we should all get off facebook, get outside, and learn to love the bodies we have.

30+ bananas a day is bananas

Originally, I wasn’t going to comment on a recent article spouting nutrition nonsense. As fired-up as I was, I felt that addressing the article would only provide more publicity for the individual featured in the article. I was torn between commenting on her ridiculous (and dangerous) assertions and leaving it alone because I think that giving this woman more coverage may do more harm than good. After mulling it over, I’ve decided to comment on the article without linking to it and without naming the woman featured. If you’ve already heard of her, I’m sure that you’ll have no trouble figuring out to whom I’m referring, even if you haven’t, you can likely google her quite easily. Still, I don’t want to assist anyone in accessing her foolishness.

Getting to the point… The article begins by discussing her belief that chemotherapy is deadly and that a raw vegan diet “will heal your body”. Yes, chemotherapy is dangerous and extremely hard on your body. It’s basically about finding the balance between the amount of toxins that will kill the cancer but not the patient. And yes, good nutrition is important for health. However, the notion that a raw vegan diet will cure cancer is total bunk and telling people to choose this over medical treatment is potentially harmful.

She also insists that losing her period on her raw vegan diet was healthy because “my feeling at the time that it felt good. At the time I think it need to happen for my body to balance out”. Since then, she has resumed having her period but they are very light. She alleges that having a period is your body ridding itself of toxicity. Umm… Actually, your period is your body shedding the unused uterine lining prepped for pregnancy every month. Not having your period (amenorrhea) is the opposite of evidence of good health. It’s an indication that your body is lacking in nutrients as it is unable to support a pregnancy. Suggesting that women who experience painful and heavy periods are consuming unhealthy diets is both incorrect and unfair to women who suffer from endometriosis.

The article mentions that she suffered from anorexia and bulimia before finding health with the raw food vegan diet. She prides herself on eating massive quantities of fruit (sometimes 50 bananas in a day!) as part of this diet, which is nearly all carbohydrate, very low in fat and protein. To me, this appears to be just another manifestation of an eating disorder. She mentions the weight loss she experienced after starting this diet and posts many photos of herself that look like those you would see on proana or fitspo sites. This bizarre eating pattern and obsession with food is not indicative of a healthy lifestyle. Yes, her figure may make her diet tempting for those who wish to be very thin. However, it is not healthy, and her advice is woefully incorrect and not based in scientific fact. Please do not be drawn in by internet sensations who promote dangerous self-serving agendas.
