Extreme ketogenic diet..
As close to zero carbs as you can get...
About 70% of your calories should come from fat, and you should have moderate protein...We'll say you shouldn't exceed 0.8-1.0 grams of protein per pound of lean muscle mass.
This should have you close to you weight lose goals..You can use your vacation to carb up, & restore energy to have sex with nice young hookers in Thailand.
Please note if you have access to ergogenic aids like steroids, fat-burners add those in two...
I would say to add in veg's as well.However, the point of this short diet is all about fat burning and suffering..
