For longevity enthusiast and former tech CEO, Bryan Johnson, almost nothing will deter him from staying true to his daily routine.

Johnson, who has reportedly spent $2 million a year to reverse age and live longer, lives by strict diet requirements, sleeping times, and daily testing. It’s precisely why Johnson – who is known for his 1,950-calorie diet and daily meal of nutty pudding (a mix of walnuts, macadamia nuts, pomegranate juice, berries, and cinnamon) – keeps to his West Coast abode. He usually forgoes in-person speaking engagements about his pursuit for immortality; this fall, he opted for a virtual interview during the Longevity Investors Conference.

However, with growing global interest and investment in the business of longevity (think longevity tourism, biological-age tests, supplements, and wearables), Johnson is sometimes willing to risk jet lag to be a part of the scene.

This week, Johnson is taking his routine abroad to India to promote his book Don’t Die, and he won’t be indulging in any of the local food, despite the country’s celebrated use of superfoods like spices, vegetables, beans, peas, and lentils.

“A lot of people ask me what I do about food when I travel,” Johnson recently wrote on X. “…This is why I’ve brought with me to India every calorie I’ll eat for 6 days.”

He adds that the decision is about the wider global food supply, which he has called “contaminated.” “This is not about India. It’s the global food supply,” he adds in his post.

Johnson will be traveling with products from his company Blueprint, which sells his $94 nutty pudding in a “ready-to-mix” form and his $86 “longevity protein.” The full “Blueprint stack,” which contains products with a range of vitamins, costs $343.

He is traveling to India with the following, per his post.
