Even though nuts are caloric, studies have shown that people who tend to eat them weigh less than their nut-less counterparts.
One study even revealed that a low-cal diet that included almonds led to more weight loss than a same calorie, nut-free diet.
How can this be, you ask? Because the fiber and protein in nuts help make you feel fuller longer.
Some researchers also suspect that nuts may slightly increase caloric burning or that not all the fat in whole nuts is absorbed.
Some nuts, particularly almonds, pecans, peanuts and walnuts have been consistently linked to reduced risk of heart disease because of their effect on your blood cholesterol.
So if someone says they are going nuts, be happy for them!
