How the Ultra-Wealthy Eat: Superyacht Chef Reveals the Secrets to the Ultimate Longevity Diet

Chris Demaillet, founder of Montclair Chef—an agency that places Michelin-level chefs with billionaire families, including Zara co-founder Amancio Ortega—notes that around 80% of the world's richest people now prioritize a life-extending diet.

At the same time, leading doctors and scientists have shared their ideal breakfast recipes, which research suggests could add up to 10 years to your lifespan.

5 Food Upgrades Billionaires Pay For

According to Demaillet, who spent 17 years working as a private chef on superyachts, the wealthiest families are overwhelmingly adopting the following principles:

1. Exclusively High-Quality Extra Virgin Olive Oil: A staple of the Mediterranean diet that has completely replaced cheaper cooking oils.

2. Wild, Line-Caught Fish: Such as wild sea bass. Chefs also strictly monitor how often predatory fish like tuna are served—especially to children—due to mercury concerns.

3. Grass-Fed Meat and Free-Range Poultry: Paying close attention to where animals come from and how they were raised has become a non-negotiable rule.

4. Organic, Seasonal Fruits and Vegetables: Seasonal produce is not only richer in nutrients, but it also avoids being shipped halfway across the world.

5. Ditching Plastic: Kitchens catering to billionaires avoid plastic containers and plastic wrap to minimize potential exposure to harmful bisphenol A (BPA).

What Experts Recommend Cutting Out Right Now

To keep your morning meal from taking years off your life, longevity experts strongly advise removing the following items from your breakfast menu:

• Ultra-Processed Foods and Processed Meats (e.g., sausages, bacon, cured meats)

• Added Sugars (e.g., sugary cereals, pastries, flavored yogurts)

The takeaway: You don't need a personal chef on a superyacht to live a longer, healthier life. Simply shift your focus toward whole plant foods, healthy fats, and lean proteins.
