100 Cal Packs Makes You Fat

Smaller-sized 100-calorie snack packs are supposed to help with weight loss, but the problem is they don’t work. In an experiment published in the Journal of Consumer Research, subjects were primed to think about their body shape and then given bags of potato chips and placed in front of a TV. The group that was given nine small bags ate much more than those given two large bags, 46.1 grams vs 23.5. What’s going on? It appears that the smaller size tricks people into thinking they’re eating less, so they feel fine about chowing down more. Consumers may merrily consume the innocently small packages of Little Pleasures at an even higher pace,” wrote the study’s authors, “leading to over-consumption.”
