I'm 5 years from breast cancer diagnosis. I decided not to have radiation or drug therapy. Fasting, IR sauna initially shrunk the tumor. I had surgery and continued with natural therapy. Cancer free and happy. No down time due to horrific treatments.

Dr. Gundry is an old giant. And you, Dr Valter Longo, are such another great. Continue with your great service to mankind. Kudos!

Dr. Valter Longo is one of the very few truly ‘world-class’ PhD longevity scientists & also ‘world-leading’ cancer research scientist. Amazing interview & brilliant to have him explain real science & practical solutions; and for having both of you together - huge thanks. 👏

Wish Dr. Gundry would advocate for allowing Ivermectin to be sold "over the counter": no prescription required. And a cancer patient comparison between "water only" fasting vs. Ivermectin + water fasting.

Dr. Gundry should interview Prof Thomas Seyfried.

Interesting. Is it possible to do the Fast Mimicking Diet in conjunction with the Lectin Free diet?

In Ethiopia, we fast for about 250 days out of the year. During fasting, we completely avoid animal products, essentially following a vegan diet. Our fasting period lasts from before midnight until 3 PM the next day—about 15 hours—without any food or water.

Traditionally, our vegan meals consist of Injera (a sourdough flatbread made from teff) paired with lentils, yellow beans, and various vegetables like tomatoes, onions, garlic, lettuce, beetroot, and potatoes. However, despite this long-standing dietary practice, many people in Ethiopia today are experiencing health issues such as diabetes, high blood pressure, and kidney failure. How come the fasting and vegan food doesn't

What is the Fasting Mimicking Diet please. I appreciate all Dr Valter Longo’s wonderful work & sharing.

[DingusCirc]

If you have cancer, youre worried about not eating for a few days??? If I had cancer, I would do OMAD then fast 35-48 hours once a week and a 4-7 day fast once a month. You can still take inulin as a pre biotic fiber for your gut microbiome while doing fasting as it will not break a fast.

Which is the best EAA supplement product which has optimal combination of all the 9 EAA for older people? Perhaps Dr. Valter Longo or Dr. Steven Gundry can advice us.

[StratosMelitis]

You understand when someone is irrelevant in the science of nutrition

When he divides the subject in only two categories: those fasting and those who eat!

Without explaining what did the patients eat!

[서상원-wm]

Which is better: More Protein Diet or More Carbohydrate Diet???

[jeanpaultongeren]

my mum wants to travel with me. But I want to eat healthy you cant eat healhy when your underway >:(

[stevemc]

When the good doctor says ‘all the data shows too much protein is bad’, can we please see the data. At least a few references.

[Dice_Rdgaming]

I thought you looked down on fasting? You confuse me Dr. Gundry

[semacaa]

He will never explain a mimic fasting even if the Dr. ask him to give a example .

[semacaa]

And everything it's with chemo involved bs

[ashx]

There is this woman Doc who just spreads "Eat proteins or u die!" I forgot her name? She looks more of a Fluencer than a (real) Doc.
