Tan, S.Y., J. Dhillon, R.D. Mattes, 2014. A review of the effects of nuts on appetite, food intake, metabolism, and body weight. Am J Clin Nutr. doi: 10.3945/ajcn.113.071456.
Tree nuts and peanuts are good sources of many nutrients and antioxidants, but they are also energy dense. The latter often limits intake because of concerns about their possible contribution to positive energy balance. However, evidence to date suggests that nuts are not associated with predicted weight gain. This is largely due to their high satiety value, leading to strong compensatory dietary responses, inefficiency in absorption of the energy they contain, a possible increment in resting energy expenditure, and an augmentation of fat oxidation. Preliminary evidence suggests that these properties are especially evident when they are consumed as snacks.
