I love to visit waterfalls.

Water sounds soothe the mind.

Calms nerves and brings down stress hormones which in turn blunt cancer signaling pathways.

Did you know that there is more that you can do for your cancer, even if you are told that your chances are slim?

Happy New YEAR!!! As we begin 2026, let us reflect on the good things from the past 365 days.

Frankly, the year 2025 was not a fun year for me.

But I still have some blessings to be thankful for.

To my team members, family, coworkers, and patients, I thank you for your unwavering support!

I look forward to 2026, and hopefully, it will be a better year for all of us.

Unfortunately, for some of us, the year 2026 will be the year when cancer makes its debut in our lives.

Life will undoubtedly be interrupted by this unwelcome visitor.

You plan to evict it as soon as possible.

You go see an oncologist for the first time.

You suddenly have a million questions, but your oncologist is in a rush and barely has time to finish their plan, write their notes, and answer phone calls. As for your questions, they usually have to wait.

You turn to Google, some turn to ChatGPT, for answers.

Unfortunately, the answers that come back may be outdated, or worse, inaccurate.

Here are some of the FAQ frequently asked questions in my email inbox:

What is the best treatment for my cancer?

Will this treatment have a decent success rate?

What can I eat or drink to improve my chances of a remission?

Are there any vitamins or supplements that can help fight cancer?

What about the BEST diet? Should I go vegan? Plant-based? Keto?

Am I doing the keto diet, or is a low-carb diet enough?

How much exercise should one undertake?

What do you think about weight loss?

So much information is out there, but the flood of information can easily confuse and overwhelm a new cancer patient.

You find plenty of online health coaches, but wonder why they all advise different things.

Unfortunately, these are the questions that YOUR oncologist SHOULD be answering for you.

I am a practicing medical oncologist, but in my spare time, I
I try to answer my ketooncologist emails as quickly and as best as I can, but there must be a better way!

This is why four years ago, I created a Facebook cancer support group (Keto for Cancer) to help you navigate the cancer journey with confidence.

It is "Keto for Cancer", and say goodbye to the confusion!

Well here we are, at the end of another year. If you are still scrambling for a unique and helpful gift, I would like to share with you a recent review that I received for my recently published book, Keto Oncology - A Comprehensive Guide. https://tinyurl.com/yc72fnwy

“Reviewer 1
Keto Oncology Jocelyn Tan, MD Congratulations on writing and publishing your book! The front cover design is attractive and the printing is high quality. You have done a great deal of research in putting this book together, and your placement of End Notes at the end of each chapter is effective both for readers who will appreciate the handy references and for those who will skip over them. Part II: Taking Action is the strongest section of the book. Here, you provide readers with the background and basics of the Keto Diet in relation to cancer and go into the specifics that research and experience have generated. You write in a largely down-to-earth voice and explain concepts clearly. The three chapters on Animal Studies are particularly interesting. Good job with grammar and proofreading.”

By the way,

I also have the Keto Code, which is the original version of this book. The Keto Code is identical to Keto Oncology but has 15 less pages since I added the menu plan and some frequently asked questions to the newer version.

Both are available online on Barnes and Noble , Amazon, and Walmart. Yes, in the USA, Canada and internationally.

Do you feel adventurous? Consider using exotic spices like curcumin, turmeric, and ginger in your next meal! They are great in fighting cancer! However, timing is everything! Be careful not to overuse antioxidants during chemotherapy, as they may reduce the treatment's effectiveness. Like any antioxidant, these powerful spices may blunt the killing effect of chemotherapy. It is best to avoid them during treatment to maximize the free radical killing effects. Also, double-check your prescription medications with your pharmacist, as dangerous drug-supplement interactions can occur. For instance, ginger can interact with tacrolimus, a drug often used by post-transplant patients. Afterwards, enjoy a cup of green tea to help block glutamine. Bon appétit!

DiD Publishing
5.0 out of 5 stars A Serious Guide to Keto and Cancer, Not Just Bacon and Eggs
Reviewed in the United States on September 9, 2025
Format: Kindle
Dr. Jocelyn Tan’s The Keto Code is not a diet fad book; it’s a deep dive into how cancer and metabolism connect, written by someone who lives in both the lab and the clinic. She unpacks complex research on cancer pathways and makes the science as approachable as possible without oversimplifying.

Be ready: this isn’t just about swapping toast for avocado. The book goes much further, into cellular metabolism, biochemical pathways, and how diet can support or disrupt cancer growth. I often had a browser open to look up references as I read, not because Tan isn’t clear, but because the subject itself runs far deeper than the typical “low-carb” conversation.

The strength of this book is its seriousness. It’s evidence-based, backed by clinical experience, and endorsed by leaders in metabolic oncology. For patients and caregivers, it offers a hopeful but grounded look at keto as a therapeutic tool. For professionals, it’s a compact but dense reference that pulls together years of research.

Yes, it can be heavy going at times, but that’s the trade-off for a book that actually respects its subject matter.

Bottom line: If you’re looking for recipes, this isn’t it. If you want to understand the science of keto and cancer, this book is a must-read. I'm reading and taking notes.

Thank you to everyone for making this happen!

Exactly one month ago today, we held the BIOFUEL conference in Cairo, Egypt. BIOFUEL, formerly known as Keto in Cairo, was a workshop conference that preceded the Cairo TECHNE conference this year.
https://cairo.technesummit.com/2025

It was well attended, and we were fortunate to have had over a dozen speakers from both the United States and Egypt.

It also happened to be EIW, Egyptian Innovators Week.

Many tech companies, startups, AI innovators, educators, and investors attended the week-long event.

I had a great time, and even rode a camel!

But now that my jet lag is gone, I wish to take a moment to thank everyone who made this event extra special.

Thanks to all our SPEAKERS! I know that you took precious time off your schedule to travel to this event. You truly elevated the quality of this event. The audience feedback was phenomenal.

https://www.ketoonc.com/biofuel-the-science-of-healing-conference

Thanks to all the ATTENDEES. We hope that you not only learned a lot, but also enjoyed the many presentations. Your feedback was much appreciated.

Thanks to my friends and family for your support and constant encouragement.

And lastly, I would like to thank all the STAFF behind the scenes. The technical support team and the administrative team of Cairo/Alexandria TECHNE. We were so busy, and I was not able to thank you all individually. Your efforts were truly the backbone of this event.

Until next time!
