A new study may have some important ramifications for beach season: Just because a food promotes fitness does not make it good for the waistline.

That was the basic finding of a recent study published in the Journal of Marketing Research. The analysis found that people who were chronically concerned about their weight and ate fitness-branded foods actually ended up eating more and working out less.

The report’s findings may come as something of a shock to health-conscious consumers, many of whom spend a king’s ransom at places like Whole Foods just to feed their dietary wants. Meanwhile, the study suggests there may be an inverse correlation between how people eat and how much they work out.
