Two meals a day may be better for weight loss than 'grazing'

We've heard for years that a key to weight loss is swapping a few square meals a day for many mini-meals throughout the day. Now, a small but growing body of evidence is suggesting all that "grazing" isn't necessarily a smart way to control your appetite. In some cases, it may even result in weight gain.

A small study presented this weekend at the American Diabetes Association conference found that people with type 2 diabetes who ate two large meals a day lost more weight than when they consumed six smaller meals with the same amount of calories.

The researchers, led by Hana Kahleova of the Institute for Clinical and Experimental Medicine in Prague, instructed the 54 study participants to follow two types of eating plans for 12 weeks each: either six mini-meals or two larger meals – just breakfast and lunch. Both diet regimens included the same nutrient and caloric content.

The volunteers lost weight under both eating plans. But eating a big breakfast and big lunch resulted in more weight loss – 1.23 points of their body mass index, or BMI. Eating the six smaller meals resulted in a loss of 0.82 BMI points. BMI uses a person's height and weight to provide a measure of body fat. A person of "normal weight" has a BMI between 18.5 and 24.9; The average BMI for participants in this study was 32.6.

Though the study was presented at the ADA conference, it's important to note that it's not yet been published in a peer-reviewed journal -- and 54 patients makes for a small sample size. Although eating just two times a day resulted in more weight loss, is skipping dinner really feasible or sustainable for the average American -- with or without diabetes? Not likely, experts who weren't involved with this new research say.

"National surveys suggest that most Americans, including those with diabetes, eat five or six times a day, so to curb eating to only two times a day would be a change that would be drastic and dramatic -- and unrealistic for many people," says Elisa Zied, a registered dietitian from New York.

Toby Smithson, a spokesman for the Academy of Nutrition and Dietetics, adds that eating two large meals a day is impractical because for many, dinner is the one meal that they're able to reliably fit into their schedule. He says, "Specifically for people with diabetes, with the mechanics of our body, it is best to spread out the doses of glucose ... throughout the day."

But moving away from "grazing" -- constantly grabbing something to eat during the day the minute you feel the slightest twinge of hunger? That's something many dietitians can get behind. And the medical literature supports that idea, too, as past research has suggested that eating more meals throughout the day does not necessarily result in more weight lost.

"It is interesting because more evidence, like this, is gaining momentum to get away from all this ‘grazing' to stabilize blood sugar," says Madelyn Fernstrom, TODAY's diet and nutrition editor. "Grazing leads to overeating for most people."

For long-term weight management, it's important to learn to listen to your body. Zied's rule: Eat when you're hungry, stop when you're satisfied, and most importantly: Plan ahead.

"What we do know is that eating less, controlling portions, and moving more are among the key strategies people--including those with diabetes--should use to facilitate weight loss and long-term weight management," Zied says.
