One of the globe’s most dedicated biohackers, Johnson spends millions of dollars each year trying to reverse the aging process and extend his life.

Through his initiative called Project Blueprint, he tries to slow down or even reverse the biological effects of aging.

What Is the ‘Don’t Die’ Diet Plan?

He works under a daily calorie guideline of around 1,977 calories, he consumes plant-based foods packed with antioxidants with little sugar content. His plan is repetitive, structured, and under close medical supervision.

The Role of Plant-Based Foods in Johnson’s Diet

  • Broccoli, cauliflower, and spinach as a micronutrient source
  • Beans and lentils as a plant protein
  • Flaxseeds and chia seeds as an omega-3 fatty acid source
  • Blueberries and pomegranate as antioxidants

Is the ‘Don’t Die’ Diet Viable for the Average Person to Follow?

Johnson’s regimen is highly individualized and monitored by a medical team. While his diet consists of plant-based, whole foods, the kind of food that is healthy for all people most people may not be able to maintain his calorie restrictions or endure his testing protocols. However, some aspects of his plan, including eating more vegetables and less sugar, are beneficial to all.
