Are Nuts a Weight-Loss Aid?

The reports about their many benefitshave come thick and fast: studies finding that people who eat nuts (tree nuts like cashews, almonds and pistachios, along with their legume pal, the peanut) live longer and healthier lives, with less risk of chronic ailments like heart disease, respiratory problems and Type 2 diabetes.
But perhaps the most startling news is that nuts may help in maintaining a healthy weight. Research has found that people can snack on modest amounts of them without gaining pounds, and that nuts can even help in slimming down.
Why do nuts appease the appetite so well? Dr. Mattes pointed to several studies.
“They’re high in protein, and protein is satiating,” he said. “They’re high in fiber, and fiber is satiating. They’re rich in unsaturated fats, and there is some literature that suggests that has satiety value. They’re crunchy, and that would suggest just the mechanical aspect of chewing generates a satiety signal.”
Snacking on nuts makes it likely that you will eat less later in the same day, according to some research. That decrease in consumption can make up for many of the nuts’ calories — as much as three-fourths of them, studies have shown.
Nuts are also resistant to digestion, thanks to the tough walls of their cells. As much as one-fifth of the fat in nuts never gets absorbed by the body, Dr. Mattes estimated in a 2008 paper published by The Journal of Nutrition. He noted some weaker evidence that nuts may cause people to burn a little more energy as they simply sit around.
Even the fat that the body absorbs from nuts tends to be virtuous. It’s mostly unsaturated fat, with lesser amounts of the saturated type whose excessive consumption has been associated with heart disease.
