In a new randomized controlled trial, skipping breakfast did not clearly worsen mood, sleepiness, or cognitive function in teenagers (13–15 y/o) when compared to regular low-GI breakfast (w/ or w/o nitrate supplementation).

This crossover trial found that a vegan diet, but not a Mediterranean diet, substantially reduced people's estimated intake of advanced glycation end products (AGEs).
I think the jury is still out on the harms of AGEs, but interesting data nonetheless.

🔎New study out from our Dartmouth team! 🔍
🧬Genetics interact with cue reactivity!🧬

"Each FTO risk allele was associated with a 30% increase in [intake]... Food cue exposure exacerbated associations between the FTO variant with gummy candy [intake]."
In an article for @Examinecom I wrote about exercise-related energy compensation (ExEC), a phenomenon in which exercise burns fewer calories than expected.

A new study analyzed a single dataset on red meat and mortality 1,208 different ways
In an article for @Examinecom, I discuss why researchers did this, what it tells us about epidemiology, and why it doesn't tell us much about red meat and health.

I found another AI-generated garbage diagram in a scientific journal.
It’s entirely gibberish and features anatomically incorrect limbs with too many bones.

Follow-up: I’ve received notice that the journal is retracting this study, due to the above graphic and a number of concerning data irregularities pointed out by @MicrobiomDigest and @TKesteman on PubPeer.
In case anyone is interested, at @Examinecom we have a guide called “How to Read a Scientific Study”. It’s a great surface-level resource for catching study limitations that aren’t as obvious as AI-generated mutant leg bones.

Most people who go on diets see weight loss plateau as time goes on. Could switching up your diet prevent this?
Maybe not. In a new study, diet-induced weight loss showed expected slowing, even as folks changed diets after 6 months (from low-fat to low-carb, or vice versa).
It's still possible that diet switching has some minor benefits (it may partially inhibit regain), but can't really say for sure until there's a similar RCT with a non-switching control group.

Does exercise help with depression? And which types help the most?
In my new article for @Examinecom I wrote about a curious meta-analysis on the topic: examine.com/research-feed/st…
I think this is objectively wrong (sorry Brady!).
There is extensive data that smoking increases mortality risk substantially more than sitting: pubmed.ncbi.nlm.nih.gov/3025…
"Sitting is the new smoking."
I think sitting is worse.
Based on some analyses, the mortality risk reduction associated with being physically active (-66%) is greater than the risk reduction associated with not smoking (-38%): sciencedirect.com/science/ar…
Sitting time and physical activity can be disentangled, as in the 45 and Up Study.

Is yogurt overrated for metabolic health?
In a new 16-week randomized controlled trial, yogurt was not clearly better than milk at improving health metrics like body fat, liver fat, blood pressure, blood lipids, or insulin resistance.

I’m excited to share my review of the book How Not to Diet!
HNTD makes a myriad of claims — with haphazard scientific accuracy — to rationalize an overly complicated diet that nonetheless seems conducive to weight loss and fairly healthy.

In a new clinical trial, a Mediterranean diet led to impressive improvements in IBS symptoms (despite no difference in FODMAP or fiber intake).
I think this could be a big step forward for IBS management. Check out my article on study for @Examinecom.

In a new analysis from the Look-AHEAD trial, achieving remission of type 2 diabetes was associated with a 40% lower risk of CVD.
Remission was more likely in the lifestyle intervention (diet+exercise) group.

“Using the structured approach to assess concordance, 15 (19.0%) out of 79 analysed diet-disease outcome pairs were concordant.”
A cohort study with 59,033 women found that eating pan-fried red meat was associated with a lower risk of T2 diabetes...
...if participants cooked their meat in vegetable oil.
(sharing bc I found it interesting, but I wouldn't read too much into it)
