Dr Thomas Seyfried is a top cancer researcher at Boston College and the author of the groundbreaking book, Cancer as a Metabolic Disease.
He developed the Press-Pulse treatment for cancer in which the individual weakens cancer cells by restricting glucose while targeting cancer with powerful oxidative therapies such as chemotherapy, radiation, hyperbaric oxygen (HBOT), or IV vitamin C.
A suggested protocol based on the Press-pulse method proposed by Dr. Seyfried is to:
Follow a ketogenic meal plan
Fast at least 14-hours leading up to a chemotherapy or radiation treatment
Break the fast shortly after treatment
Consume plenty of plant-based anti-cancer foods and receive HBOT in the following days
Follow up with subsequent fasting cycles and ketogenic eating
Another expert in the field of natural cancer treatment, Dr. Nasha Winters, has some great protocols. Here are some ideas based on her work:
Following a 13-hour fast on a daily basis (this alone lowers cancer recurrence by an amazing 70%)
Implementing 2, 16–18-hour fasts on 2 non-consecutive days out of the week.
Implementing a 3-day fast, once per month
Fasting for 3 days (72 hours), leading up to chemotherapy and radiation treatment
For very thin patients, following a partial fast or Fasting Mimicking Diet can be great around cancer treatments to prevent cachexia while lowering the side effects of cancer treatment
Very thin patients can also benefit from supplementing with essential amino acids or partaking in bone broth fasting around the times of treatment
Dr. Nasha has a great book called The Metabolic Approach to Cancer that dives into these strategies and is an excellent resource for taking control of the body’s ability to fight cancer.
A common protocol being used with success is following a ketogenic diet, fasting for at least 14 hours prior to treatment, and breaking the fast shortly thereafter. The days following are a great time to load up on antioxidant-rich plant foods and partake in hyperbaric oxygen therapy.
