Tim Ferriss · 2026-05-21 · via Comments for The Blog of Author Tim Ferriss

Sami Inkinen (@samiinkinen) is a Finnish-born, Stanford-trained entrepreneur and the founder and CEO/president of Trulia and Virta Health. Virta is on a mission to reverse metabolic disease in one billion people using technology, AI, and nutrition. Previously, Sami held roles at Microsoft, Nokia, and McKinsey & Company, after starting his career at a nuclear power plant in Finland. Sami holds an MS in engineering physics from the Helsinki University of Technology and an MBA from Stanford University.

A world-class endurance athlete, Sami is a triathlon age-group world champion and an 8-hour, 24-minute Ironman finisher, having completed the Hawaii Ironman World Championship seven times.

Sami also founded Fat Chance Row to raise awareness of the dangers of sugar and its connection to diabetes, rowing 2,750 miles from California to Hawaii with his wife—completely unsupported—while breaking a world record in the process.

SAMI INKINEN QUOTES FROM THE INTERVIEW

“Structure allows flexibility and spontaneity.”

— Sami Inkinen

“Mood follows movement and motion.”

— Sami Inkinen

“The biggest secret is saying no to 99 percent of the things that many people consider ‘normal’ so what you care [about] gets done.”

— Sami Inkinen

“Truck drivers, their concept of a lunch is McDonald’s. We can’t tell them, ‘Oh, here’s the list. Go shop Whole Foods or Erewhon, and then go home and cook at home.’ It’s like, ‘Okay, McDonald’s it is. We’re going to reverse your diabetes on McDonald’s diet.’ And by the way, we do that.

— Sami Inkinen

“The adherence of Virta patients, again, which are real Americans, not Samis, real Americans, is twice as high at one year as taking a GLP-1 drug. We have 83 percent adherence retention of patients at one year. And look at any of the publicly available data: people stick to GLP-1s like 40 percent, maybe 50 percent, 30 to 50 percent.”

— Sami Inkinen

“GLP-1s 100 percent affect your appetite. They change how much you eat, so you eat less, but they alone don’t change what you eat. … And if you don’t change what you eat, you’re not going to be perfectly or even optimally metabolically healthy.”

— Sami Inkinen

“Type 2 diabetes can be reversed systematically, not miraculously. And so hopefully I can be a messenger of hope that these conditions are reversible, especially after I already disclosed that I used to live thinking it’s your fault, it’s your fault, you are just lazy, you don’t have the willpower. But that’s not true. Nobody gets these things because they’re lazy or they decide. It’s because of our food environment. And the food environment kind of slowly but surely poisons us. But if you know a few little tricks and changes, you can actually turn back the clock.”

— Sami Inkinen

“The love language of American capitalism is dollars. And so when you can help someone else to make money, you’re going to be very, very successful.”

— Sami Inkinen

The Cash Account, which is not a deposit account, is offered by Wealthfront Brokerage LLC (“WFB”), member FINRA/SIPC.

Tim Ferriss, who’s not a client, receives cash compensation from Wealthfront Brokerage LLC for advertising and holds a non-controlling equity interest in the corporate parent of Wealthfront Brokerage LLC, which creates an incentive that results in a conflict of interest.

Want to hear another conversation about ketones, metabolic health, and what your devices might be missing? Listen to my conversation with ketogenic-diet researcher Dr. Dominic D’Agostino, in which we discussed the ketone measurement paradox of feeling sharp at low readings, the carburetor analogy for ketone production versus utilization, metabolic memory and becoming more fat-adapted over time, my 18-day keto experiment, intermittent fasting as a keto on-ramp, the glucose-ketone index sweet spot, post-meal walking and GLUT4 activation, one-week-per-month protocols, low-carb Mediterranean as the 80/20 minimum effective dose, and much more.
