Popi is a grandmother, not a doctor. If you take anything for diabetes or blood pressure, speak to your doctor before you change how you eat.

You are holding this book for one of three reasons. Your doctor frowned at you. Your trousers frowned at you. Or somebody showed you a video of an old Greek woman carrying a twenty-litre tin of olive oil up a flight of stone steps, and you thought, if she can do it, what is my excuse?

Who this book is for

  • You want to eat fewer carbohydrates, but bacon, powders and keto bars put you off.
  • You like real food with a story: Cretan dishes built on olive oil, greens and fish.
  • You are over sixty and want to stay strong enough to carry your own shopping and climb your own stairs.
  • You are looking for a present for your mother.

A note from Popi

Kalimera, koukla mou.

For thirty years I stood at a fryer in a fish-and-chip shop in Melbourne, and I ate the chips too. When I was seventy, my doctor looked at my blood test, then at my stomach, and I did not like the order he looked at them in. My granddaughter Daphne asked if I had heard of keto. I looked at her telephone and said, "Paidi mou, this is how my mother ate. Minus the potatoes."

So this book is how my mother ate in our village in Crete, and how I eat now: olive oil poured like water, greens twice a day, small oily fish, and nothing from a wrapper. It is a cookbook, a rulebook and a scolding, because somebody who loves you has to do it.

I am a grandmother, not your doctor. Read the chapter about who must ask the doctor first. I will know if you skipped it.

With love, and olive oil,
Yiayia Popi

What's inside

86 pages in five parts, with photographs throughout.

  1. Part One My Story

    A village, a fryer in Melbourne, and the long way home.

    Popi's life in four chapters: the village in Crete, thirty years of frying fish in Oakleigh, the doctor and the word "keto", and going home.

  2. Part Two The Rules

    Part rulebook, part scolding, all of it for your own good.

    What keto is, in plain words. The Ten Rules of the House. Olive oil, the seven greens, fish, and why she doesn't trust anything in a wrapper. What the first two weeks feel like, protein after sixty, and who must ask the doctor before starting.

    In Yiayia Says No, she tastes eight fashionable keto products and ranks them. Ten is the worst.

  3. Part Three The Kitchen

    Kitchen Tuesdays: Cretan food, one pan, no nonsense.

    Fourteen recipes. Each one tells you how many it serves, how long it takes and the net carbs per serving. After them comes a week of meals at Yiayia's table.

  4. Part Four Move Every Day

    The sea in the morning, the steps all day, and a kettlebell under the bed.

    Walking every day, and swimming in the sea safely. Then the Water Jug Workout: six exercises with a water jug or a kettlebell, from chair squats to the plank, with a weekly plan and a balance exercise you do while the coffee boils.

  5. Part Five Questions from the Grandchildren

    Answered while shelling almonds and cleaning fish.

    Ten questions, from fruit and beans to cholesterol and cheat days. Then a last word from the kitchen table and a glossary of the Greek words she uses.

What Daphne Found Out

Eight blue boxes by Popi's granddaughter Daphne, who studied science. They say what the doctors and the big studies say, in plain words. Where the doctors and Popi disagree, the doctors win.

For the Curious

At the back of the book, "Where the Recipes Come From" names the published recipes each dish follows. After it come 14 references: the studies and guidelines behind the health chapters, including the American Diabetes Association's Standards of Care and the World Health Organization's guidelines on physical activity. You can take them to your own doctor.

Questions

What do I get?

One PDF file of 86 pages: the whole book, with its photographs. It is not a printed book, so nothing is posted to you.

How do I get the book after paying?

When your payment goes through, Stripe takes you straight to your download page. Tap the button there and the PDF saves to your phone, tablet or computer. Bookmark that page. The button keeps working, so you can download the book again later or on another device.

Can I read it on my phone?

Yes. Phones, tablets and computers can all open a PDF, usually without any extra app. The pages are laid out like a printed book, so a tablet or computer is more comfortable when you cook. You can also print the recipes you want.

How does payment work?

Payment goes through Stripe, a large payment company. Stripe is the seller of record: it takes the payment, charges the right VAT or sales tax for where you live, and emails you the receipt. The checkout shows the price in your own currency. Your card details go to Stripe and never reach us.

Can I get a refund?

Because Stripe is the seller, refunds go through Stripe. If something is wrong with your copy, write to support@interpt.co first and we will help you sort it out.

Do I need to ask my doctor?

If you take anything for diabetes or blood pressure, yes, before you start. Eating very few carbohydrates can change how those tablets work, sometimes within a few days. Popi is a grandmother, not a doctor, and the book gives a whole chapter to who must ask the doctor first.

Is Popi real?

No. Popi, her family and her story are made up. She is a character created by interpt to present this book, and her photos and videos are made with AI. Her health story belongs to the character, so please don't read it as a result to expect for yourself. The recipes and the advice are real: every recipe follows published recipes, which are listed at the back of the book, and a dietitian has reviewed the health chapters.
