First, don’t stop yourself from enjoying the local cuisine when you’re traveling to a new city. Try to arrange your meals and snacks in the feeding windows. You can adjust your fasting times for convenience and enjoyment.
Second, stay active and keep exploring. Don’t waste your time sitting around a hotel room, get out to explore the new and exciting place.
Third, monitor your alcohol intake. Drinking alcohol does break your fast so stick to drinking in your eating window. And it’s better to limit it to no more than 2 standard drinks per day.
At last, reacclimate slowly after vacation. It’s not possible to get back to your normal eating routine very quickly after a journey. The best way to re-acclimate to your regular life is to do it slowly.
