Penn State researchers have discovered in a recent study that people who ate a large apple 15 minutes prior to lunch took in 187 less calories during that lunch than those that didn’t snack prior to the meal. (The apple contained approx.128 calories). Furthermore the apple-eaters said they felt fuller afterwards too. Of course, part of this is due to the apple containing ‘belly filling’ fibre.
But another reason for the good old apple making you feel full is that the fruit requires a lot of chewing. This in turn leads to you to thinking that you’re eating more than you really are!
