Sebastián Jasinsky trail running
The story behind the books

Sebastián Jasinsky

My first book wasn't born in a professional kitchen but in the mountains, at the most challenging moment of my life. There was a day the scale read 92 kilos (203 lb). It wasn't just physical weight; I was carrying the weight of a very hard situation that forced me to make a radical decision.

I decided to run. Not on the asphalt, but in the mountains. Trail running became my therapy and my engine. I soon realized that to climb peaks and endure the miles, training my legs wasn't enough: I had to transform my fuel.

That's how I found the keto diet. By training my body to use fat as its main source of energy, my performance took off, my mind cleared, and those 92 kilos turned into strength, endurance and vitality. My first book is the collection of the real, simple, delicious recipes that got me there.

Keto was only the first step. Since then I have been a constant seeker of a healthy life and longevity through food: Mediterranean cooking, the cuisines of regions where people reach advanced ages, and Okinawa. Each book is what I learn along the way, turned into recipes you can cook on any ordinary Tuesday. If I could do it, so can you.
