Nuts are packed with nutrition, but they are also packed with
calories. Why, then, don’t nuts seem to make people fat? In my
video Nuts and Obesity: The Weight of Evidence, I profile a
review published back in 2007 looking at about 20 clinical
trials that had been done on nuts and weight. Not a single one
showed the weight gain one would expect. All of the studies
either showed less weight gain than predicted, no weight gain at
all, or actual weight loss—even after study subjects added a
handful or two of nuts per day to their diet. However, the
studies lasted just a few weeks or months. What about long-term?
Maybe in the short run nuts don’t lead to weight gain as much as
other foods, but what about after years of eating nuts? Well
that’s been examined six different ways in studies lasting up to
eight years. One found no significant change and the other five
out of six measures found significantly less weight gain and
risk of abdominal obesity in those eating more nuts. Since that
review is now 5 years old,
