Fastest way to lose weight


I know, silly ass question but I was wondering what’s your fastest way to lose weight.... I was working out regularly and my husband ended up in the ICU for 3 days and I was told he couldn’t be alone for a few days, so I haven’t worked out in a week!! Anyway, we are leaving on a vacation on May 4th, and I still have weight to lose. What’s the fastest way you lost weight?
