What's included in reSET
Why reSET?
Most fasting programs are about what you give up. reSET is about what you get: delicious plant-based meals created by chef and founder Alex, handmade in Zurich, with yoga, mindfulness and personal support built in. Eat by Alex is trusted by more than 3,000 customers, and reSET is available for delivery or in Swiss pharmacies.
Concept – Science – Features
reSET
What is a fasting-mimicking program?
A fasting-mimicking program lets you fast for 5 days while you keep eating. Instead of a water fast or juice cleanse, you follow a set menu that is low in calories, carbohydrates and protein, and higher in fat. The concept was studied by Prof. Valter Longo at the University of Southern California, in animal studies and human clinical trials. As carbohydrates run low, the body may start producing ketones from fat, a process called ketogenesis.
reSET is our Swiss Fasting-Mimicking Program, with our own recipes and ingredients: 5 days of plant-based breakfasts, soups and snacks, about 1,000 kcal on day 1 and 750 kcal on days 2 to 5. Everything comes in one box, delivered across Switzerland, with a guide booklet, on-demand movement and mindfulness sessions, and 1:1 support on WhatsApp.

Alexandra - Founder & CEO
I founded Eat by Alex in Zurich in 2018 to change how people nourish themselves. I trained as a chef in Los Angeles under Matthew Kenney, specialising in whole food, plant-based cooking, before returning to Switzerland to build a company around food that is good for you and a pleasure to eat.
I believe looking after yourself should be simple and enjoyable. Fasting can be one of the simplest tools for it, but most fasting programs are about what you give up. So I created reSET, a plant-based fasting-mimicking program inspired by Prof. Valter Longo's research, with meals you actually look forward to. I develop every recipe myself, and every box is made by hand in the canton of Zurich.
Today, more than 3,000 customers across Switzerland trust Eat by Alex, and reSET is also available in Swiss pharmacies. I also give workshops and talks on plant-based nutrition and fasting-mimicking.
We are here to support you - message me to find the right journey for you.
