It's a metabolic fact that breakfast is the most important meal of the day. What consumers are marketed to consume for breakfast is another story.

    Yes those papers show that it is good to skip breakfast. Replied above.

How so? On HN you state facts with references usually.

It is not at all a fact, though it was widely disbursed as one for many decades in the 20th century. In fact, recent studies have proven quite the opposite, that it has almost no effect on health or mortality if someone eats or skips breakfast. There are a few exceptions, like people who are at risk of heart failure should not skip meals, but for the vast majority of the public, skipping breakfast actually has proven to have some benefits.

  Your claim is in direct contradiction to the current state of the literature. The scientific community is in consensus around the fact that late meal timing is damaging to metabolic health. Meal timing should be aligned to the body's circadian clock, which is the most active early in the day and becomes more dormant as the day progresses. People who delay caloric intake later into the day and into the evening have worse glucose control (a meal eaten in the evening can carry twice the glycemic impact as it does compared to in the morning). They also have increased triglycerides, increased levels of obesity, markers of oxidative stress, increased gut microbiota and hormone dysregulation, etc [1]. As a system, our bodies are more active in the morning than they are in the evening, which most people can identify with, so this shouldn't be surprising. It's not clear if, by skipping breakfast and decreasing caloric intake, but thereby delaying the feeding window, a beneficial effect for some individuals exists. Most of the data points in the opposite direction, but maybe, for the extremely metabolically fit individual who shovels glucose into cells like a snowplow, it's less problematic? I'm just positing, but we don't have good evidence for that. What we do have evidence for is that those who engage in IF but do it with a delayed eating schedule generally have worse health outcomes. Some references: [1] "Late eating decreased glucose tolerance, resting energy expenditure, and carbohydrate oxidation as compared to early eating. Besides, the cortisol profile was blunted for late eating as compared to early eating, similarly to that found under acute stress situations [11]. Eating late also affected the daily rhythms of peripheral temperature, towards a similar pattern to that found in overweight/obesity women which was related to metabolic alterations" Timing of Breakfast, Lunch, and Dinner. Effects on Obesity and Metabolic Risk (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893547/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893547/) "Dietary patterns that feature meal timing outside of the regular daytime hours can contribute to circadian disruption as food is metabolised in opposition to internal daily rhythms and can feedback on the timekeeping mechanisms setting these rhythms. Epidemiological evidence examining the impact of late meal timing patterns is beginning to suggest that eating at night increases the risk of weight gain over time" The Impact of Meal Timing on Risk of Weight Gain and Development of Obesity: a Review of the Current Evidence and Opportunities for Dietary Intervention (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9010393/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9010393/) There are many.. so I encourage you to look into it yourself.

I haven't eaten breakfast regularly for thirty years. Ride a bike very day, healthy as a horse. For a kid maybe, they are small and can run out of fuel so quickly. But after the age of maybe fifteen, forget it.

  Anecdata is interesting but it is not actual data :-)

    Usually true. But it is an apparent aberration of a wanna-be hard rule. A single data point is important if it refutes a rule.
