SEATTLE Women dieters who grab a snack between breakfast and lunch lose less weight compared to those who abstain from a mid-morning snack, according to a study led by researchers at Fred Hutchinson Cancer Research Center.
The results of this randomized trial, led by Anne McTiernan, M.D., Ph.D., a member of the Hutchinson Center's Public Health Sciences Division and director of its Prevention Center, will be published in the December issue of the Journal of the American Dietetic Association.
In the course of the year-long study, the researchers found that mid-morning snackers lost an average of 7 percent of their total body weight while those who ate a healthy breakfast but did not snack before lunch lost more than 11 percent of their body weight. For the study, a snack was defined as any food or drink that was consumed between main meals.
"We think this finding may not relate necessarily to the time of day one snacks, but rather to the short interval between breakfast and lunch. Mid-morning snacking therefore might be a reflection of recreational or mindless eating habits rather than eating to satisfy true hunger," said McTiernan, the corresponding author of the paper.
While snacking too close to a main meal may be detrimental to weight loss, waiting too long between meals also may sabotage dieting efforts, she said. "Snacking could be part of a dieter's toolkit if they're eating in response to true hunger. Individuals should determine if they experience long intervals such as more than five hours between meals. Adding a snack might help people deal better with hunger and ultimately help them to make more sound choices at their next meal."
The study also revealed that women who reported eating more than two snacks a day had higher fiber intake than those who snacked less frequently, and afternoon nibblers ate more fruits and vegetables compared to women who didn't snack between lunch and dinner.
