There are a number of potential mechanisms that explain why nuts may not be fattening which were explored in a recent review that appeared in the Journal of Nutrition recently. I’ve summarised them (along with one mechanism that is not discussed but I think is important) below:
Studies show that nuts tend to be effective at satisfying the appetite, which can mean that individuals just end up eating less of other foods. The percentage of calories that come from nuts that are compensated for by eating less of other foods varies from study to study, but comes in at around 70 per cent.
