10 Foods That Drive Weight Gain and Loss Identified by Harvard

A recent journal article examines the long-term impacts of small but significant lifestyle changes—especially to diet.

In a new report published in The New England Journal of Medicine, a team of Harvard researchers has revealed the results of a study of 120,877 people showing that small changes in lifestyle behaviors such as physical activity, sleep duration, and TV-watching are strongly correlated with long-term weight gain. But the most important factor was diet—and among the report's most intriguing findings is precisely how much weight gain (or loss) can be attributed to consuming an additional daily serving of a variety of specific foods over a four-year period.

The following 10 foods were found to be especially correlated with long-term changes in weight (the first five foods promoting weight gain, the second five promoting weight loss).
