Eating Breakfast is Only Half the Story
For what seems like forever nutritionists have been urging people not to skip breakfast. A number of studies show that skipping breakfast is directly correlated to weight gain- breakfast-skippers are far more likely to be overweight or obese than those who eat breakfast on a regular basis.
Eating breakfast also correlates with better performance and concentration at school and work, better energy and improved well-being.
But God is in the details, and those of us who have been on the breakfast bandwagon seemed to have left out one of the most important of those details: what's on the breakfast menu.
Because all bets are off if you choose the wrong foods, breakfast or no-breakfast.
In a new study just published in the American Journal of Clinical Nutrition, researchers did indeed confirm once again that breakfast-eaters in general eat less calories during the day, and that women breakfast -eaters (but not men) have lower BMIs (a measure of overweight).
But the study also showed that when you eat a really high-calorie breakfast you're more likely to eat more calories during the day, not less- and that the average intake of important nutrients like calcium falls!
When you think about it, this makes sense.
Really high-calorie breakfasts are almost certain to include junk like pastries, donuts, super-calorie lattes and other "foods" that have nothing to do with reaping the benefits of a solid, high-protein, low-calorie breakfast that's been shown to moderate cravings and weight gain. In fact a high calorie junk food breakfast is far more likely to lead to cravings and overeating during the day- exactly the opposite of what you want.
The moral of the story: Don't skip breakfast. But do skip the donuts.

Hi Dr. Jonny,
a very interesting post. It's true, most nutritionist advice does say breakfast is a must.
I was wondering, in this context, how would you explain the Ramadan fasting study results. I don't remember where this study was published but basically they took religious people (only because thus they could expect better adherence to the fasting), measured certain parameters like blood pressure, blood sugar, triglycerides, CRP, cholesterol etc. at the beginning of Ramadan and after 30 days when the fasting was over.
All parameters, including insulin resistance, were markedly improved at the end of the study, and participants also lost some weight, in spite of the fact that they were gorging themselves with food (no restriction) during the eating "window" which is at night.
As you probably know, Ramadan is no real fasting. They are just not allowed to eat during the daytime. So they go without food all day and start stuffing themselves at 10 pm. They are allowed to eat until 1 am, and then they start "fasting" again. So this is really a kind of intermittent fasting (IF). If you ask me, they eat at all the wrong times because after all, nighttime is the time for repair, regeneration and rest. And everybody knows that lack of sleep makes you fat!
So my question is: how can it be that that they lost weight and improved the markers, without eating breakfast and without getting proper sleep. I'd love to hear your take on that.
My experience with eating just one meal per day was great, I felt energized and alert and it was liberating not having to think about your meals all the time. (I was following Brad Pilon's advice, but I did it 5 times per week while he recommends IF twice per week. But after some initial weight loss, my results were not impressive.
However, lots of people report significant weight loss and also health improvements.
I think there's mounting evidence that occasional fasting is good for you, even one day a week. I don't have the study you mention on hand, but I don't recall that ALL parameters improved in the way you describe. Remember, some strategies that work for one goal (i.e. drinking alcohol for heart health) don't necessarily work for other goals (i.e. losing weight or brain health, neither of which alcohol is good for).
The bottom line is that people differ in their blood sugar responses to food, and that some people may be able to eat just one meal a day and do ok- i would argue that it's POSSIBLE that part of the reason we sometimes feel good when we do that is that it might generate high levels of cortisol (a stress hormone) which CAN "feel good" even though long term it's not such a great thing. HOWEVER I recognize that we're guessing here, and the fact is that if you ate one very good meal a day and felt great and energized and slept well, etc who's to argue with that? My one concern would be that it is virtually impossible to get all your nutrients from one meal.
For MOST people- not all- blood sugar is managed more effectively by spacing meals out a bit. Intermittent fasting, however, is never a bad idea, and manages insulin levels and possibly longevity genes and may have substantial benefits

Xenia,
What you are talking about is very in line with what Ori Hofmekler, the founder and Editor-In-Chief of the men’s health and fitness magazine Mind & Muscle Power, writes about in his book "The Warrior Diet." One of his principles is to eat one main meal at night. For more info: http://www.warriordiet.com/
Dr. Jonny Bowden,
I would love to hear your opinion about Ori Hofmekler's Warrior Diet. For a quick summary: http://www.t-nation.com/free_online_article/sports_body_training_performance_interviews/the_warrior_diet_an_interview_with_penthouse_editor_ori_hofmekler Thanks.
PS - I have read two of your books (150 Healthiest Foods and 150 Most Effective Ways to Boost Your Energy) and read your blog regularly. Keep up the Great Work!
