A large serving size is another factor that contributes to overeating. Just because we are hungry, we order an extra large burger or meal. Instead, we need to order a small meal, eat it slowly, finish it off and then decide if we want to eat more. Another contributor to large serving sizes is buffets. We usually end up stuffing ourselves in such situations as we get the freedom to eat as much as we want.
SOLUTION: To avoid overeating in this case, just order a meal that you can actually finish. Do not wait till you are extremely hungry. Instead of eating 3 large meals, go for 5 small meals.
