A Fried Breakfast is Healthy

Interesting that the BBC picked up on this as a potential April Fool.

Tucking into a fried breakfast of sausages, eggs, bacon, beans, mushrooms, black pudding and tomatoes is a healthier way to start the day than a bowl of cereal, according to a study in the International Journal of Obesity.
I wasn't encouraged that the original linked to the Daily Star (a UK tabloid mainly about tits), but had a look at the abstract. It is in mice, but in raises some interesting ideas.

The Press Release is here

Studies have looked at the type and quantity of food intake, but nobody has undertaken the question of whether the timing of what you eat and when you eat it influences body weight, even though we know sleep and altered circadian rhythms influence body weight," said the study's lead author Molly Bray, Ph.D., professor of epidemiology in the UAB School of Public Health.

Bray said the research team found that fat intake at the time of waking seems to turn on fat metabolism very efficiently and also turns on the animal's ability to respond to different types of food later in the day. When the animals were fed carbohydrates upon waking, carbohydrate metabolism was turned on and seemed to stay on even when the animal was eating different kinds of food later in the day.

"The first meal you have appears to program your metabolism for the rest of the day," said study senior author Martin Young, Ph.D., associate professor of medicine in the UAB Division of Cardiovascular Disease. "This study suggests that if you ate a carbohydrate-rich breakfast it would promote carbohydrate utilization throughout the rest of the day, whereas, if you have a fat-rich breakfast, you have metabolic plasticity to transfer your energy utilization between carbohydrate and fat."

Breakfast is not the time of day for carbs!

I usually have a fatty breakfast - eggs, bacon, omlette or whatever and usually a coffee made by pouring a fresh expresso into a mug of double cream. After that I am not usually hungry for the rest of the day....

Time-of-day-dependent dietary fat consumption influences multiple cardiometabolic syndrome parameters in mice

Excess caloric intake is strongly associated with the development of increased adiposity, glucose intolerance, insulin resistance, dyslipidemia, and hyperleptinemia (that is the cardiometabolic syndrome). Research efforts have focused attention primarily on the quality (that is nutritional content) and/or quantity of ingested calories as potential causes for diet-induced pathology. Despite growing acceptance that biological rhythms profoundly influence energy homeostasis, little is known regarding how the timing of nutrient ingestion influences development of common metabolic diseases.


To test the hypothesis that the time of day at which dietary fat is consumed significantly influences multiple cardiometabolic syndrome parameters.


We report that mice fed either low- or high-fat diets in a contiguous manner during the 12 h awake/active period adjust both food intake and energy expenditure appropriately, such that metabolic parameters are maintained within a normal physiologic range. In contrast, fluctuation in dietary composition during the active period (as occurs in human beings) markedly influences whole body metabolic homeostasis. Mice fed a high-fat meal at the beginning of the active period retain metabolic flexibility in response to dietary challenges later in the active period (as revealed by indirect calorimetry). Conversely, consumption of high-fat meal at the end of the active phase leads to increased weight gain, adiposity, glucose intolerance, hyperinsulinemia, hypertriglyceridemia, and hyperleptinemia (that is cardiometabolic syndrome) in mice. The latter perturbations in energy/metabolic homeostasis are independent of daily total or fat-derived calories.


The time of day at which carbohydrate versus fat is consumed markedly influences multiple cardiometabolic syndrome parameters.

And what would be the effect of fasting during the day (i.e., from evening to the next evening - and so *nothing* being the first meal of the day)? Or does black coffee change things? I see contradictory info on black coffee.

Shot of espresso in a cup of heavy cream eh. Just got on the heavy cream thing myself. Surprised at how many calories are packed into just a cup of the stuff though! (I know, I know, it's not all about the calories...)

I came to the conclusion that if I were to only eliminate carbs at one meal, breakfast was the one. Good Calories, Bad Calories said that during the night we transition into fat burning mode as insulin declines so I figured that eliminating carbs at breakfast (and ideally lunch as well) would keep me in fat burning mode for longer. Making only this change, I have lost about 10 pounds and am a 6' 0" and 173 pounds.
