In our view you are a truly excellent example of a true physician. By that we mean that you not only have the medical knowledge, skill and experience, but that you are dedicated to truly helping your patients attain good health.

Although millions of doctors sincerely do want to help patients, we all know that [many of] these doctors are unable, or unwilling in many cases, to learn about the role nutrition plays in health. Few doctors have the conviction and courage to break from what has become traditional western medicine – you are one of the best and we thank you very, very much.

Donna and Lou D.

I want to let you know how grateful I am for everything you taught me over the years about healthy ways to treat illness with and without medicine. I learned so much and have passed that info on to more people than I can count! Your advice has been life-changing and I just want to say THANKS!

Melissa Bynum Steed

Thank you, thank you, thank you! After a myriad of doctors and diagnoses, you were finally able to diagnose and prescribe the right medicines for me to take. It was a long and difficult process, but you were able to heal me – and for that I’ll be forever grateful. More importantly, I appreciate your care and compassion. You are truly the most compassionate physician I’ve ever met.

I had postpartum cardiomyopathy. Rare and almost unheard of in U.S., my ejection fracture was at 25. Thought I might die or need to be on a donor list. I was put on a low salt diet. I came across your youtube video and let’s just say I switched from diesel to gasoline. Within 6 weeks, I was off all heart meds and my e.f. [ejection fracture] went to 70. I just wanted to say thanks which seems rather insignificant since your teachings saved my life. It changed my life and my family. Thank you for sharing your knowledge.

I just listened to your interview on the Food Revolution Summit. Thank you for all the wonderful information and for being so loving and compassionate to the animals. I wish everyone could hear your message.

Eleanor Davin

I just had a chance to listen to your interview with John Robbins. You were brilliant! As always. On a personal level, I was very moved by the way you described your story and the connection between our diet and our spiritual development, which for me has been a true awakening. Your beautiful words resonated very strongly with me and I wanted to thank you for the gift of your wisdom.


I want to thank you so very much for your broadcast on the Food Revolution Summit. My fiancé and I woke up, looked at each other this morning, and said no more meat… We are both pretty spiritual and you said something in your talk that deeply effected both of us. We heard you! Thank God! So we start our journey!


About 2 months ago, I came across a video on YouTube entitled, “Food That Kills.” After watching the video, I decided to try put your advice to the test for four weeks. I stopped eating all meats and fish, eggs, and dairy products. Four weeks went by in a flash. Going back to eating the way I used to wasn’t even a thought. I’m losing weight with ease. I feel lighter and I don’t get food cravings anymore.

I recently received a notification through your mailing list about the Food Revolution Summit. I enjoyed listening to your contribution, as well as the interviews from others connected to helping us all through food.

I’ve woken up, Dr. Klaper. Your days as an anesthesiologist who puts people to sleep are long forgotten. Your message continues to impact people and change their lives. Those changes then ripple to impact the world for the better. Thank you for helping me learn that there’s a better way. Thank you for giving me a chance to avoid diagnosis of a chronic disease. Thank you for helping me enjoy delicious, guilt free food.

Matthew Terenzi

I just wanted you to know that after watching your numerous videos via YouTube, especially the Food That Kills documentary, I’ve recently changed my major in college to Food and Nutrition and I’m hoping to get into the coordinated dietetics program with my university.

I came across your documentaries after searching for some information on a vegetarian lifestyle and they were the true factor that helped me decide that Nutrition and Diet are truly what I am interested in, especially from a biological standpoint.

Evan Hudson

The course of my life has been altered because of Dr. Klaper’s work.

I am what I would consider to be an ‘average’ male, 37 years old, with no major medical issues. Until 6 months ago, my diet mainly consisted of chicken, beef or fish, or the dreaded double pepperoni pizza.

This is when a friend forwarded me a YouTube link of the Foods That Kill presentation from almost 20 years ago. I distinctly remember watching the video at 11:00am.

The video is an hour long. During the video, I was recalling all the members of my family that had died from prostate cancer, heart failure, breast cancer, etc. Almost all of the men in my family above 55 have had either a heart attack, heart surgery, or some form of cancer, and most have diabetes.

Until I had seen the video, I firmly believed I was doomed to fall into the same category, and that there was nothing I could do about it. I had been slowly expanding over the last decade and, about a year ago, started exercising – not quite as often as I should, but much more than I had in the past. This inevitably increased my appetite. Due to my muscle building workouts, I was led to believe I should eat lots of lean chicken to get in shape. I was eating an entire roasted chicken per day for dinner, plus deli meat and cheese sandwiches for lunch. I was ignorant to say the least.

Upon finishing watching the video, I subsequently threw my lunch in the garbage, and went grocery shopping. Since that day, that very minute, I have not had any meat, dairy or eggs. I feel fantastic, And can’t be thankful enough.

My friends tease me daily about my diet, especially when I order at a restaurant, but all I can do is smile.

Brad Kettyle

I wanted to express my gratitude and thank you for being an amazing doctor, healing and curing and making human lives better.

I am starting my career as a Certified Health coach and I am reading lots of books and materials and getting more and more familiar with many natural doctors who have been practicing for years. Thank you for your contribution to this society; it’s very valuable. I am hoping to bring your knowledge and the knowledge of other fellow natural doctors to my country, Slovakia.

Eve Oman

I was a vegetarian with allergies and a lot of eczema before I discovered your elimination diet. It changed my life. After 7 days of the diet, my eczema was going away and, when I reintroduced foods, one at a time, I discovered than gluten was the reason for my eczema. I have been living gluten-free and eczema-free for 7 years now and I wanted to thank you.

Christine Fournier

I did a 21 day water fast at True North & I can promise you that this man, Dr. Klaper, is the kindest, most genuine & caring doctor I have ever met in my entire life. He is completely devoted to his patients both male & female & wants nothing but the very best for them. I am a 30 something female who had both serious physical & severe emotional issues when I arrived at True North. This man is a diamond. He loves what he does, he loves his patients. He is a brilliant, brilliant doctor


I have loved watching your videos. They have made me understand what food does. I have enrolled in a degree course in food science to get qualified in the UK, [inspired] purely by you and Dr. John McDougall.

Thank you for changing my life and my diet and for giving me a thirst for knowledge.

David Robertson

I have watched your video, “A Diet for all Reasons” over and over. This is absolutely the very best video I have ever seen on why we should not be eating animal products! You do not know how many people are seeing the light because of wonderful doctors like you! Thank You, Dr. Klaper!

My wife and I have became vegans after watching your video and learning from all of the other wonderful plant based doctors like you!

My father-in-law who turned 75 this year, and who has always ate the Standard American Diet [SAD], watched your video with us one night. Right after the video ended, he looked at us and said, and I quote, “I feel better just thinking about not eating meat!”

And, he immediately started his path to being a vegan the very same day! That is how good this video is – someone, even at his age, can change just like that!

Monty Mansfield

THANK YOU, Dr. Klaper…I have very much enjoyed learning from your videos. Your conversation with John and Ocean Robbins may have had as much impact on my future as anything I have come across. Your love, your dedication, your enthusiasm is totally awesome.

Thank you for your efforts and your glorious example. I shared your video about cholesterol with friends [and it] has changed their ways. My best friend saw his cholesterol drop from 250 to 170 in the past year with no meds and he has never felt better.

David K.

I want you to know how much I appreciate you taking the time to respond to my inquiry. I will abide by your advice and hope for the desired results. I fully appreciate the massive number of such inquiries you must receive, and yet you took the time to share your knowledge and concern.

Thank you sir! May you enjoy the feeling of well-being that you so graciously give to others.

Tom K.

Just wanted to thank you for our session. I appreciate your kindness, excellent listening skills, generosity (in every way) and breadth of knowledge. I am happy to have you on my team of health care providers.

Sylvia Israel

Dr. Klaper was my supervising physician during my own water fast at True North and I give him my highest recommendation. I got great results there and it was a life-changing experience.

Diane Bassett

I too was fortunate enough to have Dr. Klaper supervise my fast at TrueNorth Health Center in Santa Rosa with great results. My ulcerative colitis finally is in remission after 10+ years of misery and I’m feeling really well. Dr. Klaper is as good a teacher as he is a physician, and this DVD is excellent. In fact, all of Dr. Klaper’s lectures are worth watching, in my opinion. Check out his DVD “Digestion Made Easy: A Journey Through Your Digestive System.”


I learned more about my digestive system (and my body) by investing just over an hour watching this DVD (Digestion Made Easy) than I had learned my whole life. This DVD should be required viewing for every human being. It’s like a manual for one of the most critical systems in our bodies. And you’ll also find clear explanations of, and easy-to-implement solutions to, a variety of common conditions, including heartburn, constipation, hemorrhoids, and even that embarrassing gas.
