The mini 100-calorie pack craze is now waning. These packs are becoming less popular as consumers  become more concerned about budget and sustainability, according to a report by market research firm Mintel— plus the packs did not work for weight control.

Kraft introduced of the first 100-calorie packs in 2004 with a line that included Oreo Thin Crisps, Wheat Thin Minis and Nabisco Mixed Berry Fruit Snacks. Copy-cats Kellogg and General Mills, followed suit later that year. Last year, there were 190 100-calorie pack product introductions.

The mini-pack business had been booming — until recently. According to the Mintel report, consumers have figured out how to measure 100-calories worth of product themselves; those  concerned with sustainability don’t like the extraneous packaging; and taste is also a factor, as 100-calorie packs of Oreos are sans the cream filling.

The focus is changing away from 100-calorie portions, says Joan Holleran, director of research for Mintel, it’s now on “portion control plus — plus whatever benefits the companies can impart – fiber, antioxidants…”
