Big Breakfast Alters Appetite, Gut Health

- hristov 7mo agoInteresting but they had no control.
- baxtr 7mo agoThe whole study design seems odd. Why not add a third high-fiber + high-protein group for example?
- AnEro 7mo agoI feel like the regular weight loss group was? Since it isn't necessarily rocket science for having mostly men stay in an easily determinable caloric deficit to lose weight. (Women have usually would be harder due to more conditions and hormone interactions that make finding a TDEE not as simple.)
- Apocryphon 7mo agoThey didn't eat that much.
- benmaraschino 7mo agoThey used a crossover design, so each subject served as their own control. Not a bad choice for trials like this as you gain a lot of statistical power with fewer participants than a parallel-arm, non-crossover design.
- hristov 7mo agoI don't think they used crossover design. There is no evidence in the abstract that they used crossover design. If they used crossover design they should have all participants go through a second trial period where they consume the same diet but with light breakfast and more caloric lunch and dinner. Then they could actually have more insight on the main thesis of their study, i.e. whether bug breakfast alters appetite.
- benmaraschino 7mo agoThey did. Check out Figure 2 in the paper.
- hristov 7mo agoThey did a crossover study on the two diets. Ie the high protein diet and the high fiber diet. They did absolutely no crossover or no control on the headline thesis of their paper. The headline being that big breakfast alters appetite or is somehow good for weight-loss. This study shows or proves absolutely nothing about advantages or disadvantages of big breakfast or that a big breakfast makes any difference whatsoever. It only shows that if you are going to have a big breakfast as part of calorie limited diet if you choose a diet with high protein you will lose weight slightly faster but will have slightly worse gut health than if you chose a diet with high fructose.
- chairhairair 7mo ago19 participants.
- Oras 7mo ago>> 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?
- AnEro 7mo agoSomeone with quotas
- godelski 7mo agoYou'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.
- steve_adams_86 7mo agoEspecially in dietary studies. You either spend a lot on high quality, controlled studies where you can nail down parameters (takes a LOT of labour), or you spend on facilitating much larger studies where you make up for precision and control with volume. There are trade offs in either case and some types of research where one is more suitable than the other. But the best case is a combination of the two, and it's exceedingly rare. Maybe there are other options but this seems to be the polar nature of these studies from what I've seen.
- irishcoffee 7mo ago> We saw this effect in a small study, so it's worth doing a larger study. That never happens.

- abainbridge 7mo agoThe 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 https://www.bmj.com/content/364/bmj.l42
- tonyedgecombe 7mo agoThe problem there might be what people are eating for breakfast.
- DANmode 7mo agoRight. How many of these studies used buttered eggs and potato as the sole breakfast?
- irishcoffee 7mo agoIt means the replication crisis is alive and well.
- natex 7mo agoYou 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 healthier gut microbiome, Study 2: Whether to Eat, Broad Demographics, Systematic Review (meta analysis), Broad Clinical Outcomes, Conclusion: eating breakfast increases total daily energy intake compared to skipping it, and that skipping breakfast resulted in slightly greater weight loss.
- IAmBroom 7mo agoUncool. OP asks for help understanding, and you attack them for not understanding.
- dfex 7mo agoIt sounds like this study might have been funded by.... Big Breakfast. I'll see myself out.
- nobody083648 7mo agoDammit I came here to make this joke
- jagged-chisel 7mo agoThe IHOP/Waffle House duopoly ramping up the science to validate their ideals.
- mike_d 7mo agoTLDR: A weight loss diet centered around a big breakfast yields weight loss results. That breakfast loaded with protein made you feel fuller and suppressed your appetite (which helps you follow a diet), where a fiber loaded diet produced more beneficial gut bacteria. The study has a pretty small sample size, but it seems well designed and matches what you'd expect.
- puppycodes 7mo agostudy says we should do a real study
- maleldil 7mo agoYes, 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.

- puppycodes 7mo agoI think the frustration is: it's not "news"
- jeffbee 7mo ago"big meal alters appetite" is a hell of a conclusion. Definitely going to need to study that one.
- DANmode 7mo agoAppetite is intertwining endocrine functions that contain way more moving datapoints than just stomach empty vs stomach full.
- geodel 7mo agoBig, if true.
- olalonde 7mo agoCountries 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.
- dollylambda 7mo agoBuddha 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.
- swah 7mo agoOMAD people usually do the opposite: black coffee and then a big dinner.
- tzs 7mo agoThis study wasn't big breakfast vs light/no breakfast. It was high fiber big breakfast vs high protein big breakfast. (And no, this comment was not written by an LLM).
- kibibu 7mo agoThe 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)
- sevennull 7mo agoIntermittent fasting + eat breakfast like a king, lunch like a prince and dinner like a pauper worked miracles for me.
