Countries known for big breakfasts: USA, Turkey. Countries known for light or skipped breakfasts: France, Japan, China. I think I'll wait for a more thorough study.

The study doesn't try to say that big breakfasts are good or bad in general (it leans on previous works for that).

It's trying to determine the impact of the composition of said breakfast.

The full title of the paper is: "Big breakfast diet composition impacts on appetite control and gut health: a randomized weight loss trial in adults with overweight or obesity"

(I don't think "with overweight" is a great turn of phrase)

The abstract begins, "Growing evidence supports early eating to control appetite and energy balance". What does that mean? My unskilled reading of it is that there is recent evidence that eating breakfast helps with weight loss. But I'm confused because there was a 2019 meta-analysis that found that eating breakfast does NOT help with weight loss. https://www.bmj.com/content/364/bmj.l42

You might want to read the rest of the studies - or at least try to no misrepresent before commenting. There are elementary differences in the studies. Study 1: "What to Eat", Specific Demographics, Primary Clinical Trial, Mechanistic/Physiological Outcome, Conclusion: High-Protein breakfast is superior for suppressing appetite and maintaining satiety, while a High-Fiber breakfast promotes better weight loss and a he…

I wasn't comparing the two studies. I was just asking what the first sentence of the abstract of study 1 meant when it appears to be a false statement given study 2's result. Usually this is because I don't understand something and someone around here explains what I'm missing.

Buddha recommended to his followers a diet which consisted of a breakfast and a second meal at noon if needed. That is, for their health, primary meal early in the day and fasting the remainder. It's interesting that this advice seems fairly supported by science.

OMAD people usually do the opposite: black coffee and then a big dinner.

Earlier quoted context omitted.

That was the point I stopped reading.

The number needed for a study to get significant results depends on the strength of the effect it is measuring. For example if I have a bag full of thousands of coins, pull out 19 at random and flip them sequentially, and they all come out heads I'm going to conclude I have a bag that is overwhelmingly coins that are heavily biased toward coming up heads. Are you going to say my sample size was too small to support t…

True, or you can have a prior about how many people you need to get a significant result in a certain area.

I have one for "diet changes have large impact" and the number is different enough feom 19 that I'm happy to stop reading at that point.

>> therefore 19 participants completed the study (2 females and 17 males) and their data are presented throughout Who in their own mind decided that this is a "study" worth publishing?

You're reading the study wrong. You read We saw this effect, so it's real. In actuality it is We saw this effect in a small study, so it's worth doing a larger study. It's worth publishing because it's evidence and motivation to do further studying. And if you're asking "Why not start large?" the answer is obvious: money.

> We saw this effect in a small study, so it's worth doing a larger study.

That never happens.

That doesn't change the meaning.

Reading it wrong tends to make that happen too. Since people read it as fact they end up arguing "why fund a more expensive study to show the same thing?"

A lot of this stems from not understanding how science actually works. How there's never proof, only confidence bounds

study says we should do a real study

Yes, because you need evidence from small studies to justify running larger ones. You're not going to run an n=1000 experiment from a mere guess.

I think the frustration is: it's not "news"

Uncool. OP asks for help understanding, and you attack them for not understanding.
