OmeletteIn early April I blogged here (“A Completely New Way to Think About Weight Loss”) about a fascinating new study that suggests when you eat certain foods may be as important as what you eat. Researchers from the University of Alabama at Birmingham found that mice who ate breakfast with more fat than carbs metabolized fat and other foods better throughout the day and avoided weight gain. Meanwhile, mice who started out their day with carbs didn’t metabolize as well, tended to eat more overall, got chubby and developed symptoms that can lead to heart disease.

Then I followed up a week later (“An Easier Way to Lose Weight”) with my own seven-day weight-loss experiment based on this study. I ate fat and protein like eggs, cheese and nuts for breakfast, with my only stipulation being no carbs before noon. No other changes.

I told the study author, Molly Bray, Ph.D., a professor of epidemiology at the University of Alabama at Birmingham, about my experiment, and she was intrigued and said she might try it herself. What were our results? Read more

Assorted Donuts on whiteFavoring fat over carbs at breakfast may help you avoid cravings later—and maybe even lose weight, says a fascinating new study from the University of Alabama at Birmingham.

It may also prevent metabolic syndrome, that nasty bunch of symptoms including abdominal fat and high cholesterol that can lead to cardiovascular disease. At least it does in mice. But from what I’ve seen in nutritional studies of mice and rats, they behave pretty much like we do when it comes to eating.

The mice who were fed a higher-fat breakfast pretty much maintained their weight, but the carb-breakfast little guys got fat and developed the signs of metabolic syndrome. The researchers say starting with fat seems to turn on your ability to metabolize fat efficiently and also allows for metabolism of other kinds of foods throughout the day. But starting with carbs seems to turn on your carb metabolism and it just keeps going so you crave more more more. (You know that feeling!) Read more
