Please join me in welcoming Guy Tenenbaum. Six years ago, Guy was diagnosed with stage 4 cancer, also known as metastatic cancer. This means the cancer had spread to at least one organ. People with stage 4 cancer are typically given a few weeks to a few months to live.

A cancer cell comes from a normal cell that has damage in the mitochondria. The cancer cell adapts, takes alternative energy pathways, and can live without oxygen.

When Guy was diagnosed 6 years ago, he was told there was nothing that could be done, that it was too late, and to enjoy the rest of his life. His cancer had spread to his bones, lymph nodes, and lungs.

Guy explains that he didn’t do any chemo or radiation because there was no treatment plan proposed to him. Guy discovered Thomas Seyfried's work and decided to see if it could help. He discovered the benefits of prolonged fasting and even completed a 40-day fast.

Some people can do extended fasting, but if you’re unable to comfortably fast, the fasting-mimicking diet may be beneficial.

Guy continues researching new protocols and trying to stay one step ahead of highly adaptable cancer cells.

    This is absolutely amazing! In my personal experience, I’ve been able to heal from a condition they can’t even understand called “ACHALASIA ESOPHAGUS.” When I was younger, I had no choice but to fast most of the time because food would not go down my throat. I fasted for weeks at a time! NO, I DIDN’T STARVE, and I was extremely healthy growing up! After a surgery where they clipped and removed part of my esophageal muscle to hopefully fix the condition that they never fully understood, it got worse, and they claimed it would turn into cancer later. They scheduled an operation where they would remove part of my esophagus and use part of my colon to replace my esophagus. I declined to get surgery. Instead, I started fasting. I got rid of toxic drugs, foods, and lifestyles. I added essential amino acids to my fasting, and today, I have no problems whatsoever with my esophagus! No cancer, no inflammation! Congratulations, and stay strong, Guy! 💪 Thank you kindly, Dr. Berg! Have a great day, everyone! 🙂

    I was diagnosed with stage 4 nsc Ling cancer, that metastased to my kidneys in 2013. It took 21 months of chemo to go into remussion. The chemo cost me my gall bladder due to stones. 21 months later, I was diagnosed with adrenal cancer in my right kidney. 18 months after surgery I was diagnosed with adrenal metastases which was radiated. In April 2022, they diagnose breast cancer leading to more surgery. My oncologist confessed he did not expect me to live. I am still here but my quality of life has deteriated. But I am still breathing. Modern medicine had kept me alive but at what cost . 😢

    I have stage 4 lung cancer and I’ve had at least two rounds of chemo & immunotherapy. I felt good when diagnosed but once treatments started it’s been all down hill. I’ve stopped my treatments once I got blood clots and my immune system is very bad. I’m now on the Tippins protocol which I began about 2 months ago during my chemo but never told my dr. I can’t fast due to other health issues. At age 70 quality of life is more important to me. When the cure became worse than the disease I knew I had to stop. My second scan showed dramatic improvement, even my Dr was surprised. I’ll continue the protocol but no more chemo. I pray for my miracle and will definitely help others if I’m cured! ❤

      Good for you, but I don’t understand why you would share this without mentioning anything whatsoever about the “path” you took, since cancer is still cancer and doesn’t go away on it’s own. So if you share something like this about how you overcame DCIS, it kind of leaves people hanging about how you went a different direction from the standard protocol. Not that you have to go into details, but I just feel like you’re sharing something that could be very misleading to someone else that’s being diagnosed with cancer.

My Oncologist is ‘rubbing his head’ and uses the word, miraculous considering it metastasised from my Bladder to my Liver. Lymph nodes were all clear.

The doctors and nurses were always telling me how well I was handling the chemo. The doctor looked at my blood work each week and told me I was a very healthy cancer patient. Other than fatigue, I had no real side effects. I had an ultrasound last week and the tumors are gone. My oncologist said a lot of people have a good response to chemo but I have responded exceptionally well. I also ate very well, whole foods, lots of cruciferous veggies. I drank broccoli sprout powder in my garlic/lemon water every day. I walked and jumped on my rebounder. Lots of people prayed for me every day and God is good. Thank you, Dr. Berg, for all of your videos. I did what you recommended and I am a survivor.
