Kellogg co-chief executive officer Carlos Gutierrez commented this week that the trend towards low-carbohydrate has reversed and is now in decline.

Gutierrez said that the apparent downturn had left supermarkets with oversupplies of low carb products marketed at dieters, reported Bloomberg.

“While we are clearly seeing that the low-carb trend, or fad, has peaked and it looks like it is taking a bit of a dive in the supermarkets, we have yet to see the recovery of those categories that were impacted by low-carb,” Gutierrez said. “I would hope we see that in the future.”

US food companies introduced an estimated 65 products in the past three months that make claims of having lower carbohydrates, Gutierrez said on a conference call with investors.

About 10% of U.S. adults were on low-carbohydrate diets in the second quarter, down from 12% in the first, according to a survey of 2,500 people in late June commissioned by Morgan Stanley analyst Bill Pecoriello.
