ELI5: When you freeze something, does it's shelf life remain the same after you defrost it?

For example: 

I purchase a loaf of bread. It expires in 7 days. I get home and realize I already have bread so I put the new loaf in the freezer. A month later I take it out and defrost it. Do I still have 7 days until it goes bad?

EDIT: conditions are exactly the same when you take it out of the freezer, as the manufacturer of the product intended. 

If bread is a tough one, then use meat. You freeze a pound of ground beef for a month and then take it out and put it in the fridge. Will it still have the same shelf life as when you froze it?

edit: The simple answer is: No, the shelf life is shorter after being defrosted.

The short answer is no, freezing tends to damage foods a little. This damage breaks the food down slightly allowing it to spoil faster. However, you can keep food frozen for a long time, and just take it out when you are ready to use it.

That being said, I'd still use the thawed-out bread past the 'shelf life' until it started showing signs of mold. Just because the shelf life is a set number of days, doesn't mean it instantly goes bad on that day. If you're not sure though it's better to throw it away.
