> 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.

> Meal skipping has become an increasing trend of the modern lifestyle that may lead to obesity I believe them that this is correct but does anyone know why? I thought all the "intermittent fasting" folks were losing weight?

This is the problem with all weight loss and dieting studies and anecdotal evidence. Nothing is ever fixed or set in stone. Some people lose weight with lots of small meals. Some lose weight with one big meal. Some find low carb works, others eat carbs and lose weight. Human metabolism and body weight regulation is very complicated and doesn't readily yield to simple rules or heuristics (beyond CICO).

This is only n=17 and 7 days long. Not particularly useful. AFAIK it's pretty well accepted in the keto fasting world that prolonged skipping of meals can lead to insulin inflexibility. Meaning it's good to have a cheat day to prevent your body from becoming overly adapted to fasting.

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 agree that we shouldn't read much into this. But I do suspect that, if an n=17 study came to the opposite conclusions, supporters of intermittent fasting would never stop citing it.

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. It depends ENTIRELY on the subject under study. More is not always better and in many cases completely unnecessary.

Here is a decent guide. You may wish to read it so you can learn when you can dismiss a study based on N. You never mentioned, did you back out the study numbers and determine the N=17 number was outside the range of statistical power? If so, would you mind posting your calculations?

My best guest, and this is pure speculation, is that skipping a meal makes people believe that they can eat whatever they want for the other meal(s) of the day. As such, they eat awful food and never develop good eating habits.

I did OMAD (one meal a day) for a while and when I was researching it, many places encouraged this behavior. The idea being that if you skip 2 meals, even if you eat like garbage for your one meal, you won't be able to eat as many calories. This worked for me, I ate whatever I wanted for dinner and I lost ~20lbs in a month, but my cholesterol levels increased so I put a stop to it. Then, I put the weight right back on because, well, I never actually changed my eating habits -- only the frequency.

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.
