Re: oh no…there’s a wedding coming up

No, I’m not. But I’m pretty sure I’ve been asked that before.

The fatter you are, the longer you will survive without food. Fat contains a lot of energy - I don’t understand why you would want to ingest it from a diet (that’s like playing the antagonist role against your own goal)? You can continue doing what you want, but it will just take longer for results to appear.
A normal human body can survive ~2 weeks without any food (after this time, all of the fat is completely burned off). Obese persons can survive for ~1 month.
