Vitamin D Workshop NEXT VITAMIN D WORKSHOP: JUNE 24-27, 2025 MONTREAL, CANADA

I’m looking forward to presenting some of our research on the effect of exercise on vitamin D at the Vitamin D Workshop in Montreal next week.

Vitamin D levels can be lifted by exercise, new study finds A university study finds regular exercise during the winter can keep Vitamin D levels up.

It’s lovely to see our research on exercise and vitamin D reaching the mainstream. www.bbc.co.uk/news/article...

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial

The key to getting vitamin D in winter without using supplements A new study looked at how to get vitamin D

The effect of an acute bout of exercise on circulating vitamin D metabolite concentrations: a randomised crossover study in healthy adults Abstract figure legend Thirty-three healthy adults (14 ♀, 41 (15) years, body mass index 26.2 (3.7) kg/m2, V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_{\mathrm{2}}}{\mathrm{max}}}}$ 36.2 (9.2) ml/kg/min; mea...

Collectively, there seems to be a double benefit from exercise - a transient increase in key vitamin D metabolites around each bout (shown in our previous acute exercise RCT below), and longer term sustained positive effects on basal concentrations.

Mobilising vitamin D from adipose tissue: The potential impact of exercise Vitamin D is lipophilic and accumulates substantially in adipose tissue. Even without supplementation, the amount of vitamin D in the adipose of a typical adult is equivalent to several months of the....

We previously speculated that exercise might mobilise vitamin D from adipose tissue. Adipose can contain enormous amounts of vitamin D. This didn’t seem to happen but, as we discuss in the paper, interpretation is complex and there is a lot to consider. onlinelibrary.wiley.com/doi/full/10....

The preservation of active vitamin D (1,25(OH)₂D₃) is particularly notable given that supplementation doesn’t seem to have such an effect. Our take home if you don’t want to read on - Exercise should be promoted alongside supplementation to help maintain vitamin D status

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial In people with overweight or obesity, regular exercise even without weight loss or vitamin D supplementation completely prevents the usual winter decline in the vitamin D metabolite that maintains he...

Another good reason to exercise! The VitaDEx RCT demonstrates that regular exercise without weight loss positively affects vitamin D metabolism and status during winter. advanced.onlinelibrary.wiley.com/doi/full/10....

This is patently not true. The two robust RCTs providing causal evidence (which we refer to in this piece) were funded by the US National Institutes of Health - not industry.

The public deserves better.

And, they are ignoring the strongest evidence. We now even have celebrity doctors claiming that “the whole idea that you can burn more calories by doing exercise was funded, if not by Coca Cola, then by the soft drinks industry”

Is it the science - and the intriguing notion that physiological systems have evolved which conspire against our efforts to make changes that would be positive in modern-day environments?

Whatever the motivation - they have got carried away!

Is it knowing that many of the general public will enjoy articles allowing them to scoff at the futile behaviour of people who might otherwise appear virtuous (exercisers)?

Why do journalists find the constrained energy expenditure narrative so enthralling? Is it because it gives the impression we have all been duped?

This illustrates some of the bombardment. There are many more. It makes a great teaching topic - evidence, science, media - it has it all.

This piece is based on our paper, sciencedirect.com/science/arti..., which is well worth a read to see how statistics informs physiological inferences. The study of a very important physiological hypothesis being compromised by correlating X with Y-X and getting excited about a -ve slope.

Exercise does increase calorie burn – but probably not as much as you might hope Some experts have theorised our total daily calorie burn is limited – but research shows us otherwise.

Are you being bombarded with messages telling you that physical activity won’t increase energy expenditure because it is constrained? Here is our little piece on this topic for The Conversation. @uk.theconversation.com
theconversation.com/exercise-doe...

Perspective: Is the Response of Human Energy Expenditure to Increased Physical Activity Additive or Constrained? - PubMed The idea that increasing physical activity directly adds to TEE in humans (additive model) has been challenged by the energy constrained hypothesis (constrained model). This model proposes that increa...

That’s not to say that there might not be some interesting interactions as we discuss in this paper. pubmed.ncbi.nlm.nih.gov/36828336/
I just think we need to be careful not to throw away the baby with the bath water!

The constrained model is certainly interesting, but I don’t think we are ready to say that people who are really active burn the same as people who are really sedentary. Indeed, during the RAUSA experiment, the athletes burned >5,000 kcal/day - not many sedentary people will get anywhere near that!
