CHICAGO (CBS) — Fewer people are sitting down to a big breakfast in the morning.

Instead, WBBM Newsradio’s Regine Schlesinger reports, they are stretching it out over hours, snacking throughout the morning.

“Breakfast in stages,” as the practice is known, is a growing trend.

“They eat something at home, then stop at Starbucks or a convenience store,” said Liz Sloan, head of a food industry consulting group.

The breakfast food industry is exploiting the trend.

General Mills, Quaker Oats and other companies are adding to their lineups of breakfast bars and yogurts. Jimmy Dean is out with mini breakfast sandwiches and McDonalds and other fast food places have expanded their breakfast menus.

But nutrition experts worry it’s a trend that could add to America’s obesity epidemic, with people less aware of how many calories they’re getting when they switch to repeated snacking.
