About the book

No diet. No cookbook. Just a three-week programme you do at home.

You'll learn how your blood sugar drives your energy and mood, why your gut has a say in how you feel, and how, as long as you can handle a knife and a spoon, you can make easy, tasty meals your body really needs. After 21 days you've got the system down and you take it from there: repeat, vary, build your own GOOD. lifestyle.

Tanja Thielen in her GOOD. kitchen
I'm Tanja

I don't believe in diets. I do believe in understanding what your body needs.

I'm Tanja Thielen, health strategist and bestselling author. After more than 25 years in healthcare and health coaching, I keep seeing the same thing: people only change for good once they understand how their body actually works. So I translate the science into plain language you can use tomorrow, with German directness and Dutch gezelligheid (a word so good, English never made one of its own).

For a very special time

Pregnant (or nearly)?

Together with midwife Petra Lomartire I wrote a book about staying naturally in balance during pregnancy: rest, food and essential oils, safely explained from the first trimester through to the postnatal weeks. On the pregnancy page you'll also find a free guide with ten oils and recipes.
