Can fasting actually weaken cancer — and make chemotherapy work better?
In this episode of Integrative Cancer Solutions, Dr. K sits down with longevity and nutrition science pioneer Dr. Joseph Antoun to break down the emerging research on fasting, fasting-mimicking diets, and precision nutrition for cancer. Dr. Antoun explains why cancer thrives on growth signals, how traditional “eat more calories” advice may backfire, and what the science really says about starving cancer while protecting healthy cells.
This conversation explores fasting-mimicking nutrition before chemotherapy, immune rejuvenation, autophagy, growth factors like insulin and IGF-1, muscle preservation, and why food-as-medicine may dramatically improve treatment tolerance and outcomes. If you or someone you love is navigating cancer — or wants to reduce risk through longevity-based nutrition — this episode delivers critical, science-backed insights you won’t hear in a standard oncology visit.

Newly diagnosed with cancer and wondering how natural therapies can support your treatment?
Integrative Cancer Solutions with Dr. Michael Karlfeldt is a podcast on integrative oncology, natural cancer treatment, and holistic cancer care, helping patients and caregivers understand how evidence-based complementary therapies can work safely alongside chemotherapy, radiation, and surgery.
What makes this show unique: you'll hear real patient consultations, not just expert theory. Each episode explores how integrative therapies, including high-dose vitamin C, mistletoe therapy, ozone therapy, nutritional support, and immune-boosting protocols, can help manage the most common side effects of cancer treatment: nausea, fatigue, neuropathy, weight loss, inflammation, and immune suppression.
Studies show that more than half of all cancer patients use some form of complementary medicine during treatment, yet most have no reliable guide for doing it safely and effectively. With over 35 years of clinical experience and as the founder of a leading naturopathic oncology center in Idaho, Dr. Karlfeldt brings real clinical insight to every episode, helping patients reduce their learning curve, improve quality of life, and support long-term healing and survivorship.
