What to Eat

When you’re Fasting

These recipes are derived from the research of Valter Longo, but not endorsed or approved by Dr Longo or his lab.

Dr Longo’s research shows that a water fast of 4 or more days can trigger a reset of the immune system. As we get older, our blood contains too many memory T-cells, each programmed to combat a particular microbe, and not enough naive T-cells, which respond to new challenges. Fasting purges and rebuilds the immune cell population with naive T-cells.

There is also an enduring effect on insulin sensitivity, which is a primary driver of aging.

Many people find it difficult to sustain a zero-calorie fast for 4 days, and Dr Longo has developed a 5-day diet program that delivers much of the benefit with less hunger. It’s not exactly a free lunch, but at least to some extent you can have your fast and eat it, too.

Dr Longo endorses a program under medical supervision using a package of prepared vegan foods, including herbs and caffeine. His company is called L-Nutra and the packaged 5-day diet is sold under the brand name ProLon. Prolon web site.

The recipes below are satisfying vegan meals with the same calorie content and macronutrients as the ProLon diet. Each recipe has about 360 calories, in the form of 9% protein, 44% fat and 47% carbohydrate.

 

Instructions:

Each of the recipes below is sized for one meal. Choose 3 meals for the first day, 2 meals for each of the following 4 days.

This diet is not intended for weight loss, and is not appropriate as a long-term regime.

Enid’s Vegetarian Lao Crispy Rice Salad


  • 1 cup white rice (Jasmine or medium-grain; or brown)
  • 3T Thai red curry paste (about half a small can – I used Panang curry)
  • coconut or other oil spray
  • ½ - ¾ block of extra firm tofu
  • 1T peanut oil (or other light vegetable oil)
  • 1T soy sauce
  • 1t salt
  • 1T sugar or brown sugar
  • ½ cup flaked coconut
  • 1/3 cup thinly sliced shallots (could use scallions or onions)
  • 1/3 cup roasted peanuts, chopped
  • ½ cup chopped fresh mint
  • ½ cup chopped fresh cilantro (also can add ½ cup chopped fresh basil)
  • 1 tsp red chili flakes (optional – depends on how hot the curry paste is)
  • 1 whole lime, juiced (more if desired)
  • whole lettuce leaves/optional additional vegetables – raw and/or cooked

Cook the rice with 1 cup of water (more if using brown rice). Mix cooked rice with the curry paste. Take a large nonstick roasting pan and spray with coconut (or other) oil. Spread the rice/curry mixture in a thin layer to cover the bottom of the pan. Spray a little more oil on top. Bake in the oven at about 325 degrees until the rice is dried out and crunchy. May take about 30-40 minutes – more or less depending on oven temperature and wetness of rice. You can flip chunks of it over as it’s getting dry. When done, remove from oven and let cool.

Cut the block of tofu into four thin slices. Use a kitchen towel to squeeze out excess water. Then place the slices on a dry towel on a plate and lightly salt the top with coarse salt. Microwave for 3 minutes, flip slices, re-salt, and microwave another 2 minutes. The tofu will become drier and firmer. When they’re cool enough to handle, chop the tofu into small cubes. Heat the peanut oil in a nonstick or cast iron pan and lightly fry the cubes, tossing them about to get all surfaces fried. Set aside when done.

In a large bowl, mix together soy sauce, salt, sugar, coconut, shallots, peanuts, mint, cilantro, and chili flakes. Break the crisped rice into chunks and add to salad, along with the tofu. Squeeze lime juice over everything and mix well, adding more lime, salt, chili, sugar, or other ingredients to taste.

Add cooked vegetables if you like – such as green beans or broccoli. Also can add raw cucumbers and/or sweet peppers.

Serve with lettuce leaves, placing a big spoonful or two on each leaf, rolling up the salad in the lettuce leaf and eating.

Sauted Asparagus with mushrooms
