I have skipped breakfast since college when I was much more concerned about bulking up. I drink two coffees and that gets me through til lunch. I’ve never really considered alternatives to this routine. If I wanted to experiment with breakfasts what do people recommend eating? The priority would be energy levels, and mental clarity since I tend to work better in the morning.

Banana on toast, or just a banana to begin with

> Background: Meal skipping has become an increasing trend of the modern lifestyle that may lead to obesity and type 2 diabetes. That is not what I was expecting this to be about. Now I'm thinking, how does this relate to the intermittent fasting trend? Are people meal skipping and calling it intermittent fasting? Or are the people who are meal skipping generally not interested in "wellness community" trends like IF?

It's just a clumsy sentence. They are trying to say that modern lifestyle leads to obesity, not fasting.

> Eating in misalignment with the biological clock (e.g., skipping breakfast and consuming bigger meals in the evening or eating late at night) is associated with an increased risk of obesity and type 2 diabetes (1, 2). On the other hand, popular trends such as breakfast or dinner skipping are advertised for weight management; however, conclusive scientific evidence to support these suppositions is lacking (3)

First sentences of the introduction.

> In conclusion, a causal role of breakfast skipping for the development of obesity is not supported by the present data.

Last sentence of the paper.

Will try this for sure. Love that bananas are portable by design.

n=17, so read nothing into this result. Also, what they tested is having no fixed eating schedule. The effects (if any) of skipping breakfast every day consistently are not measured.

i don't get why some studies have so few partipants. How hard is it to recruit people for something like this? We're not talking rare diseases.

All that screening and testing costs a lot of money.

I'm the same as you but I'll usually have half a banana or an apple.

Nutritional studies are notoriously difficult to conduct. You either have to isolate subjects and monitor everything they eat and when. Or you have to rely on self reported data and people do an atrocious job of tracking food, estimating portion size, etc.

This study did the former:

> The duration of the study is 7 days including 3 days with controlled diet and 4 days (including 5 nights) in a metabolic chamber at the Institute of Nutritional Medicine at the University of Hohenheim.

I imagine it was prohibitively expensive to have more participants.

The problem is not N=17. If the effect (difference between skipping breakfast vs dinner) was large enough, it would be obvious and significant even in a small sample. The effect seems to be very small.

I agree that what is missing is to measure skipping meals for a longer time period, like a month, at least.

These comments are always so hilarious. It demonstrates a significant lack of understand of how statistics actually works. You see this on reddit all the time, you'd think it'd be better here. Power and sample size are determined by numerous factors depending on the question under study. You could have N=10 be statistically powerful and N=1,000,000 be statistically meaningless.

This is clinical nutrition. There are so many confounding factors that it is not reasonable to draw any conclusions about how the body works (especially as a layman reader on HN) from a study that tested 17 people. Indeed, their own introduction claims that previous larger studies have found no correlation between meal plans and effects on the body, at least wrt caloric expenditure.

I do have a PhD, but thank you for your input anyway.

Would this be an intuitive way of putting it? If I pull a random 17 phones off an assembly line, and 16 of them are defective, I can pretty confidently say there is something wrong with the whole product line even though n=17?

But the entire field of medicine is based on small studies with high power to achieve statistical significance, that lead to sequentially larger studies and eventually regulator approval or rejection. Are you saying the entire field is a sham? I urge you to write to the FDA immediately them to inform them that their methodology is gravely flawed.
