What's the fastest way to lost some fat?

Ok I know that losing fat really fast is super unhealthy and is not the way to go about things, but it would only be this one time. It’s not what you think though, I’m not an overweight person trying to get skinny. Here’s the deal, the past month or so, I have been eating way too many bad foods, a lot of pancakes, and burgers, junk like that. I gained some pounds. I’m not overweight, I promise. It’s like that baby fat that I’m trying to get rid of you know?

I have a birthday party coming up with like 500 people that are coming! it’s coming up in about 2 weeks, I know this sounds bad but I just need to lose those pounds, and fast. like really fast. So what are all the best possible ways I can just lose that fat? and no I would not consider throwing up, that’s doing a little too much. But again, that doesn’t mean I’m not willing to try other things!

One thing I was thinking I could do, even though it’s unhealthy, (but remember this is like a one-time thing), would be to eat half as much as I usually do, but work out like I always have been? but then I was worried that eating half as much might backfire on me seeing that I might lose energy for doing that, not being able to workout as hard you know? I don’t know….

So please, don’t tell me that this is a bad idea or whatever, just please tell me all the best possible ways I can lose fat.. fast…again, it’s like baby fat is what it is!! I do cardio and I weight lift, I am 19 years old and am a male. thank you!
