PLEASE BE AWARE, THAT THIS IS NOT A SERIOUS DIET , It is a tongue in cheek take on a personal experience!.
Below is my step by step guide to my Nepalese Curry Diet. To achieve the same results as I did, you need to follow these instructions precisely, as even seemingly unnecessary steps, such as step 2, are critical in achieving noticeable results -

Before the "diet"
1.Arrive in Kathmandu
2. Eat Doggy Chicken Curry at a truck-stop cafe. I know, everyone says don’t eat it, but you need to show your travel companions how cool you are, l even though you know it looks “sus”.
3. Find cheap hotel in Pokhara, and proceed to spend next 24 hours completely emptying contents of your stomach, both intestines and bowels. Make sure you sweat profusely the whole time. Don’t leave the room, in-fact spend the entire time either in your bed, or on the bathroom floor.
4. Wait until the stomach craps stop, then prepare to head off on 8 day Annapurna Base camp trek. Don’t eat before you go, as you cannot stomach anything.
5. Walk approximately 170km, continually ascending and descending hills and valleys, to you reach a maximum height of 4130m above see level. Stop for water and soft-drinks regularly, but completely loose your appetite. Find the only food you could even contemplate eating is soup (luckily Nepalese garlic soup is sensational), which you eat twice a day.

After the "Diet", 8 days later
6. Finally leave the path a Phedi, and taxi back top Pokhara. Go to dinner in town and (finally) devour a steak (buffalo, not cow). Weigh yourself to find you have dropped 6kg…EASY!!!
It should be noted, the Annapurna Base camp trek is still one of the most amazing experiences I have embarked on, and, in addition, apart from the truck-stop snack, I would gladly repeat the entire experience at the drop of a hat. Kathmandu is a must see city on any adventures list, and Pokhara is a wonderful town to spend a week or more. I still long for the Garlic Soup sometimes, as it was truly wonderful, and obviously nourishing!
REMINDER – THIS IS NOT A REAL DIET
