Dr. Stephen D. Phinney on Making a Low-Carb Diet Sustainable Long-Term

This is a great interview with Dr. Stephen D. Phinney – one of the authors of a book called The Art And Science of Low-Carbohydrate Living.

He’s had 25 years of clinical experience prescribing a low-carb, ketogenic diet for patients and has been in constant ketosis for 6 years himself.

It’s a great interview, he gives a lot of actionable tips on how to make a low-carb diet both sustainable and enjoyable in the long term.

A few interesting points from the video:

  • It can take up to 4-6 weeks to fully adapt to a ketogenic diet and taking “a break” from the diet to eat some carbohydrate can interrupt this process.
  • The Inuit who lived in Arctic regions sustained themselves on a near zero carb diet in exceptional health.
  • They preferred to eat meat with a lot of saturated and monounsaturated fats. If given the choice, they would rather use the polyunsaturates from seals to fuel their lamps.
  • After a hunt, they would cherish and eat the fatty parts of the meat and feed the lean parts to the dogs. Yes, to them “lean meat” was dog food.


A ketogenic diet can be very healthy and many modern studies have shown that it is beneficial for both weight loss and health improvement.

However, same as with most restrictive diets, sticking to it in the long-term can be difficult.

If you are able to stick to such a diet, then your body and brain can adapt to burning fats and ketones for fuel.

Many people report feeling excellent and having lots of energy after they have managed to adapt to such a diet.
