Nutrionists and weight loss experts have often suggested that eating a big breakfast might keep you full throughout the day and help prevent overeating at other meals, but a new German study published online Jan. 17 in the Nutrition Journal, says eating a large breakfast may actually derail weight loss.

When it comes to losing weight and body fat, diet and exercise are most effective when done together as opposed to following either weight loss strategy alone, according to new weight loss research published online April 14 in Obesity.

If you're looking to lose weight and excess fat, you might want to focus on reducing your stress and getting the right amount of sleep, according to researchers from Kaiser Permanente's Center for Health Research in Portland.

In fact, although diet and exercise are the usual prescription for losing excess weight, high stress and too little sleep (or too much of it) can hinder weight loss even when people are on a diet and exercise, the researchers report.

The report, funded by the U.S. National Institutes of Health, is published in the March 29 online edition of the International Journal of Obesity.
