Reduce Portion Size

• The availability and consumption of larger portions may facilitate excess energy intake resulting in obesity, especially if they have been made attractive through value size pricing (i.e. lower unit prices for large than for small portion sizes).^{1, 2} A super-sized burger meal can contain more than 2300 calories. The exercise equivalent of running a marathon would be necessary to burn these calories. Physical activities may not be able to counteract the excessive caloric intake, and allow time for work, sleep, and other daily activities. (See portion size)
