I’ve found the following steps useful to minimize Jet-Lag when traveling Eastwards:

• Eat vegetarian food starting 2 days before the flight
• Water fast for 36+ hours from 10 hours before the flight
  • this means no solid food or snacks during the flight
  • no alcoholic drinks
• Sleep/rest on the flight Eastwards, stay awake on the flight westwards
• Break fast with heavy vegetarian lunch in new time zone
• Stay awake until new time zone’s evening
• sleep for 12 hours
• Breakfast light on carbs
• heavy lunch
• Go outside sit in the sun early in the morning
• No alcohol for 2 more days in the new time zone
• work-out if possible
