Are you thinking about doing the Big Mac diet? The Big Mac diet is when you only eat Big Mac cheeseburgers for 30 days straight. This is actually proven to be highly unhealthy and bad for you and we do not suggest it. However, if you want to look like you gained a few pounds (or many pounds) in a very short time, then get this Super Size Mask. You’ll get the supersized look while still maintaining your health, but go ahead and indulge on those extra large french fries if you want to! This holiday is all about tasty snacks.
