Almost 7 years ago, while going through some personal issues, I made a terrible mistake and ended up being convicted of driving under the influence (DUI) in the State of California. It was a dark period in my life, but I have moved on and learned my lesson. This spring, however, my intoxicated driving conviction […]
To be taken with a grain of dietary recall data, but a new study, Children’s Attention-Deficit/Hyperactivity Disorder Symptoms Predict Lower Diet Quality but Not Vice Versa: Results from Bidirectional Analyses in a Population-Based Cohort, found that an ADHD diagnosis led children to a less healthy diet, whereas less healthy diets did not lead children to ADHD.
The study was conducted in the Netherlands and it followed 3,680 children starting at age 6 and then ending when they reached the age of 10.
Put plainly, though more ADHD symptoms at age 6 were associated with less healthy diets at age 8, diet quality at age 8 was not associated with ADHD symptoms at age 10.
There are a number of proposed pathways to help explain how ADHD might affect diet quality. ADHD and its impulsivity may increase the risk of binge eating or loss of control eating, and the impact of ADHD on neurotransmitters may affect hunger and fullness. It’s also possible that some parents of children with ADHD may offer foods their children prefer in order to decrease risk of conflict and/or reward desired behaviour.
Clearly more research on this would be welcome.

European fund managers are casting an increasingly skeptical eye towards the oil industry, concluding that the industry’s financial future looks grim, according to a new survey published by a London-based organization today.
Just 18 percent of the responding fund managers, including representatives of firms based in the UK, France, Spain, and Italy, predicted that “oil companies will be good investments if their business is still focused on fossil fuels in five years’ time,” according to the survey, published by the UK Sustainable Investment and Finance Association (UKSIF) and the Climate Change Collaboration.

A new analysis by Clean Technica found that global investment in carbon capture and storage technology (CCS) adds up to roughly $7.5 billion total. It also examined how much, for that investment, CCS has reduced atmospheric carbon dioxide (CO2) levels compared to an equivalent investment in renewable power generation.
The analysis calculated that “wind and solar are displacing roughly 35 times as much CO2 every year as the complete global history of CCS.” Clean Technica’s Mike Barnard concluded, “CCS is a rounding error in global warming mitigation.”

Former top Trump environmental officials Scott Pruitt and Ryan Zinke, both forced out of their jobs last year under the weight of, for each, an absurdly large number of ethics scandals, have now resurfaced, with each accepting influence-peddling jobs in industries they previously regulated. The two also appeared jointly at a recent Texas Republican event and demonstrated that each man remains utterly shameless.

On April 23, the U.S. Environmental Protection Agency (EPA) told two environmental groups that it had decided it was “not necessary” to update the federal standards handling toxic waste from oil and gas wells, including the waste produced by fracking.
State regulators have repeatedly proved unable to prevent the industry’s toxic waste from entering America’s drinking water supplies, including both private wells and the rivers from which public drinking water supplies are drawn, the Environmental Protection Agency concluded in a 2017 national study.

Early in the morning on April 24, an ethanol train derailed, exploded, and burned near Fort Worth, Texas, reportedly destroying a horse stable, killing three horses, and causing the evacuation of nearby homes. According to early reports, 20 tank cars left the tracks, with at least five rupturing and burning.
While specific details have not yet been released, it appears to be a unit train of ethanol using the federally mandated DOT-117R tank cars, based on the images showing tank car markings. This is now the third accident in North America involving the upgraded DOT-117R tank cars, all resulting in major spills of either oil or ethanol.
One of the possible reasons that in freely living humans exercise doesn’t seem to add up to weight loss as math might predict is that freely living humans might eat back their burned calories. Some may do so consequent to increased hunger. Others to a sense of virtue and the inclination to reward themselves for their hard work. Others still because marketing has convinced them that they must refuel, recover, replenish, etc..
A new study,Activity energy expenditure is an independent predictor of energy intake in humans, published this year in the International Journal of Obesity, set out to look at this phenomenon.
Now to be clear, the study certainly wasn’t designed to explain exercise’s impact on weight. It was just 7 days long and it involved the retrospective analysis of data from 5 prior studies and did not directly measure energy expenditure or energy intake. Instead researchers utilized estimated energy expenditure by way of heart rate and indirect calorimetry data, and energy intake by way of known to be problematic food diaries.
My stats skills are nowhere near good enough to comment on the various treatments of the data, but here’s the scatter plot of the impact of energy expenditure on energy intake.
The increase in energy intake the authors attributed to energy expenditure wasn’t high, roughly 3% of total daily calories (around 70 in this sample), an amount too small to explain away exercise’s often uninspiring impact on weight loss.
Truth be told, I’d have predicted the difference to be larger as eating more consequent to exercise is something I know many people do for one or more of the various reasons mentioned above.
Of course none of this changes the fact that exercise has tremendous health benefits at any weight and that weight shouldn’t be your driver for upping yours if you’re able.

Back in 2012 I first posted my wish for there to be a questionnaire that would serve to help individuals and researchers determine how easy or difficult a particular diet would be to follow.
I called it the Diet Index Enjoyability Total or DIET score, and my hope was that by using a series of simple Likert scales (descriptive scales from 1-10), researchers could set out to evaluate a particular weight loss approach’s DIET score where high scores would identify diets that could actually be enjoyed, and where low scores would identify under-eating, highly restrictive, quality of life degrading, dieting misery. This would be useful both to individuals who could use the DIET score to evaluate whatever approach they were considering, but might also serve as a surrogate for shorter term diet studies to give a sense as to whether or not there’s a low or high likelihood of long term adherence to a particular study’s strategy.
I’m happy to report that thanks to the hard work of Michelle Jospe and Jill Haszard of the University of Otago, along with your responses, we have completed the DIET score’s qualitative review and this survey is meant as a simple pilot to test the hypothesis that higher scores associate with longer term success, and we hope, that once collected, these results will be compiled along with our qualitative review for the DIET Score’s first published preliminary study!
So again, if you’re currently following a diet, or if you’ve recently quit a diet, we would greatly appreciate it if you were able to take just a few minutes of your time to fill out our quick survey by clicking here.
Thank you in advance!
[Today’s survey is the final one (hopefully) before we submit our paper on the DIET SCORE. Consequent to our first two surveys we tweaked our questions to make them more relevant and representative by way our your comments and expert feedback. Even if you filled our survey out last time, if you’ve been successful on your diet (any dietary strategy or approach, we’re not picky) OR if you’ve recently quit your diet, we’d dearly love to hear from you and we promise, it will barely take 2 minutes to complete]
Coca-Cola has gone on record to state,
“Parents tell us they prefer to be the ones teaching their children about beverage choices. That’s why for over 50 years we’ve adhered to a company policy that prohibits advertising soft drinks to children”
So clearly their newly announced plans to sell Star Wars themed bottles at Disneyland and Disneyworld must be targeting adults.
Nothing wrong with a liquid candy company trying to sell liquid candy (that’s their literal job after all), but don’t lie and pretend you don’t target children with your marketing or that you care about anything other than profit.

First some disclosures. As far as diets go, I’m egalitarian. I believe that the best diet for you may be the worst diet for someone else, and that all diets work by way of reducing caloric intake, but that calories from different foods will have differing impacts upon health and satiety. As far as Gary and Stephan go, I like both of them. I’ve had the opportunity to have a number of offline conversations with Gary over the years and though I’m guessing we generally spent the majority of our time in those chats disagreeing with one another (sometimes rudely), for reasons I find difficult to pin down, I’ve always enjoyed them. Stephan is someone whose work I’ve been reading for years and whose opinion I respect and value. And the 3 of us, in 2017, were involved with the Cato Institute for an online debate on sugar.
With those out of the way, onto the debate.
I certainly hadn’t planned on writing about it. And I won’t spend too much time nitpicking the discussion. Suffice to say, as many already have, it seemed that Gary the journalist relied on stories to make his points, while Stephan the scientist relied on studies. Gary constantly interrupted Stephan, and somehow also managed to recurrently mispronounce his name (despite corrections), and Stephan, perhaps as a consequence, at times treated Gary dismissively.
If you’re looking for a more detailed play by play of the entire 2 hours and 37 minutes, by all means, here’s Layne Norton’s fairly exhaustive (and even time stamped) coverage, but what I want to cover today are a few thoughts inspired by the debate rather than the debate itself.
Much of the low-carb high-fat (LCHF) (now in many cases interchangeable with #Keto) world has raged on for years about mainstream medicine and science’s disregard for their chosen diet and theories. An old photocopy of an American Heart Association pamphlet from 1991 that indeed promotes sugar consumption gets trotted out as some sort of gotcha for 2019. Young keto adherent physicians proudly tweet of the “torture” they experience reading opinions on diets other than their own (disclosure – including mine). Cardiologists with bestselling LCHF diet books write breathless articles in newspapers championing the idea that everything you’ve been taught about diet and heart disease is wrong and encourage the specific consumption of saturated fat. Self identified “science journalists” (note, this isn’t actually a dig at Gary but rather others) who purport to care about evidence embrace and amplify the most idiotic of theories, stories, or comments so long as it suits their narratives. And if a study contradicts any of the aforementioned folks’ belief systems, the fault is said to no doubt lie with the methodology, or the researcher being conflicted (as Gary repeatedly suggested in the debate when discussing the work of his former NuSi hire Kevin Hall, as well as Jim Hill and colleagues’ metabolic ward study that utilized direct calorimetry to show that people gained equal amounts of weight when overfed fat or carbs), or both. And of course pretty much all of the most vocal gurus, even the ones from prestigious institutions like Harvard, appear more than happy to extend their credibilities to prop up whatever medical quack (Mercola, Oz, Hyman, etc.) is willing to promote them.
For various reasons, listening to this debate reminded me of all of that.
Despite Gary’s very real comment in regard to diet related chronic disease and society that,
“Tragic shit is going on“
it would seem to me that the bulk of the energy spent by the loudest of the LCHF/#Keto crowd is mustered trying to prove everyone else is wrong or conflicted, and that there is only one, true, right, best, diet – a message that’s especially off putting when it comes from MDs, given every single day physicians are reminded that different treatments work differently for different people – sometimes predictably, and sometimes not so much – which is why for instance for hypertension there are at least 10 different classes of medications, and multiple options within each.
The starkest difference between Gary and Stephan I think comes at the 2:24:08 mark where Stephan details how much he loved Gary’s Good Calories, Bad Calories and how he found it so persuasive that he personally adopted a LCHF die, but that then he turned from the historical narratives conveyed in Good Calories, Bad Calories, to the science, and he found that the science told a different story. Not a story that suggested LCHF was a bad diet, or the wrong diet, or an unhelpful diet, but just that the science underlying Gary’s hypothesis doesn’t hold water for Stephan. And then over the course of the next few minutes, in what I can only assume is his rebuttal, Gary tries to narratively explain Stephan’s personal, subjective, experiences on LCHF diets, and then discounts the various studies Stephan mentions as being poorly designed while trotting out one study he does like from the 60s that to his reading, supported his assertions.
And I know this wasn’t the point of the debate – it was a debate after all – but wouldn’t it be grand if instead of the constant need of so many (and yes, there are definitely exceptions – see note at end) to promote LCHF/#Keto as the one right, best, only, diet, instead LCHF/#Keto, especially those who are themselves researchers and health professionals, took a deep breath and realized that if tragic shit is indeed going on, that perseverating on motives rather than data, and fanning the flames of online outrage mobs, and propping up of quacks like Mercola and Hyman, and promoting the worst examples of science and opinion so long as it suits their narratives, and fear-mongering around statins, and spreading the bizarre notion that there’s only one right diet and that anyone who suggests otherwise is wrong and likely conflicted, while providing fodder for online debates, is indefensible, unhelpful, and a very real reason why there’s far less embrace and research of a strategy that absolutely has a place in the treatment and prevention of diet and weight related diseases.
(And for an example of a keto adherent physician who bucks the aforementioned trend, look no further than cardiologist Ethan Weiss who just the other day penned this great post about keto, LDL, and treatment, all the while embracing science and reason)
