Chocolates and Fat

Listen up, butterball! You think life is all sunshine and rainbows, don't ya? You probably spend most of your day looking at food. Well, this is how it is for you: The joke plays on the "life is like a box of chocolates" saying, but twists it by saying that if you are fat, you're gonna finish the chocolates quickly. It's a bit of a self-deprecating remark on how you eat too much and don't live a long life because of it.
