Lastly, they discovered those who consistently increased their nut consumption by half a serving daily had a 23% lower chance of putting on 11 or more pounds within the same time frame.
According to the BMJ press release, the team suggested, "Snacking on a handful of nuts rather than biscuits or crisps may help to ward off the weight gain that often accompanies aging and is a relatively manageable way of helping to curb the onset of obesity."
Although the scientists noted their study was observational, they hypothesized why nuts could help with weight control."Chewing nuts takes some effort, leaving less energy for eating other things, they suggest, while the high fiber content of nuts can delay stomach emptying so making a person feel sated and full for longer," the release read.
"Nut fiber also binds well to fats in the gut, meaning that more calories are excreted. And there is some evidence that the high unsaturated fat content of nuts increases resting energy expenditure, which may also help to stave off weight gain."
