Every Diet Works For Someone, No Diet Works For Everyone, Diets Are Difficult - IF 2021 Edition


Joining an ever increasing cavalcade of studies of different diets that demonstrate they all work as well or as poorly as one another comes this week's A randomised controlled trial of the 5:2 diet published in PLoS. 
In it researchers randomly assigned 300 participants to receive either:

1) "Standard" brief contact in the form of a 20 minute chat, and the provision of a booklet discussing UK's national dietary guidelines and a leaflet of various local weight management resources, 
2) 20 minutes of Q&A on IF dieting and provision of a leaflet describing 5:2 style intermittent fasting (IF - where two non-consecutive days of the week people are instructed to eat 500-600 calories total), or 
3) That same IF leaflet and chat as above plus 6 weekly one hour group support sessions spread over the first 6 weeks of dieting.
What'd they find?
1) There was no difference in weight loss between groups at 6 months or 1 year post randomization (average loss of just under 4lbs but with some individuals up to 20lbs)
2) Roughly 50% of the participants of each group dropped out within the year
So I guess the same old unsexy conclusion as always. 
Every diet works for someone. No diet works for everyone. Why? Because diets are difficult to sustain unless you happen to enjoy the one you're on.
And to that end, stay far away from healthcare providers claiming there's one best way to lose. Your best diet is someone else's worst.

The World Health Organization, For #WorldDiabetesDay, Chose Fat Shaming And Stigmatization

Where to start with this?

First off there are more than 2 types of diabetes (I mean even the tweet lists 3), but really, recognizing World Diabetes Day with an infographic of a person with obesity in bare feet on a Lazy-Boy eating a giant bag of chips? 
That's certainly the gluttonous sloth narrative that much of society subscribes to, but the WHO? 
And yes, weight, diet, and physical activity correlate with diabetes risk, but for the WHO to dumb things down to people with type 2 diabetes are fat, lazy, gluttons? The mind boggles.
Never mind genetics, social determinants of health (including poverty, education, caregiving requirements, etc), co-morbid medical conditions, and more, the actual World Health Organization on World Diabetes Day, is stating if you have type 2 diabetes, it's your fault.
This of course also ignores the fact that there is just a staggering amount of privilege required to intentionally and permanently prioritize behaviour change around food and fitness in the name of health, and of course denies the reality of the thousands of genes and hormones known to be involved in the regulation of weight and dietary choices.

Perhaps this will serve as an opportunity for the WHO to take a closer look at weight and diabetes bias and stigma and focus some resources to help educate the world on the dangers and risks therein. For over 24 hours, they'd simply added a tweet to their offensive, misguided, and erroneous thread stating they'll take into account the feedback they've received in future messaging, then yesterday afternoon, they finally took it down. Here's hoping we see a thread about implicit and explicit bias from the WHO down the road

2021's Dumbest Scientifically Published Exercise Recommendation For The Treatment Of Obesity

[First written blog post since March 2020. What an awful 20 months. Though the pandemic is certainly not over yet, it feels like it's time to start writing again. Not sure what the frequency of posts will be, but it's nice to be back]
I wouldn't have believed it was real if I hadn't seen this phenomenon so many times before - a research study trying to tie their findings to the treatment of obesity despite the findings being either incapable of leading to clinically meaningful weight loss, or ridiculous to suggest in the first place. Here we've got both.
Published in Cell Reports Medicine, the paper Altered brown fat thermoregulation and enhanced cold-induced thermogenesis in young, healthy, winter-swimming men looked at the brown fat stores of Scandinavian men who alternate brief outdoor winter swims with a dash to the sauna 2-3x weekly. 
What'd they find?
The non-randomly selected winter swimmers, all 8 of them, whose average BMIs were 23.7 and whose average age was 25, were found, when exposed to cold, to generate more heat from their brown adipose tissue than their 8 age and weight matched controls. 
How many calories did that brown adipose tissue heat generation burn? If we take their results at face value (their results are orders of magnitude higher than found in a prior study of albeit older subjects), they report that during a "cooling period" of 30 minutes (there was no difference during a "comfort state"), resting energy expenditure was higher in the winter swimmers by an extrapolated 484kcal/24hours. They also reported that winter swimmers spent on average 11 weekly minutes in cold water. So during those 11 minutes the winter swimmers might well be burning 3.7 more calories than their non-winter swimming counterparts - the equivalent number you'd consume eating 1/10th of a carrot. 
The paper is full of various hypotheses to try to tease out the findings from this very small study. 
But what struck me was their final conclusion, 
"Finally, our findings motivate investigations of winter swimming as a lifestyle intervention for increased energy expenditure in obese subjects as a potential weight loss strategy."
Really? Your n=8, non-randomized, observational study of young men without obesity, that didn't control for any weight related variables, which showed that during their 11 minutes of winter-swimming the swimmers might burn 3.7 more calories per week for 4 months than non swimmers motivates investigations of winter swimming as a potential weight loss strategy in people with obesity?

Saturday Stories: Hygiene Theatre, The Lost Plot, Caving To Antivaxxers, And a Brief Announcement From Me

Justin Ling, in Macleans, on the persistence of hygiene theatre
Sarah Zhang, in The Atlantic, on how we've lost the plot on COVID.
Announcement wise - well I think it's time for me to start blogging again. Though COVID is definitely not gone, with vaccinations coming for our children, I feel more comfortable amplifying topics not-COVID related. Look for first post back this week highlighting the stupidest appeal to obesity in a journal article that I've ever seen. Also, it's that time of year again, and should any of you want to donate to my Movember fundraising, here's the link
