Ken B

“As a family doctor, I learned that my patients could lose weight and keep it off with the ketogenic diet; I began recommending in 2016. Many of my patients have used this diet to reverse metabolic diseases that they had been told were life-long and progressive.”

“I recommend low-carb and keto diets with and without intermittent fasting to all of my patients who have lifestyle-related chronic conditions, because of the science behind these approaches and their impressive clinical results. I also recommend they visit the Diet Doctor website to find trustworthy information and delicious recipes.”

“For the 10,000 members we see a year, why do we recommend a nutrient-dense, low-carbohydrate approach to improved health and well-being? Three reasons: It is founded on real science. It’s composed of real food. It delivers real results.”

Charles C

“Our medical practice was featured implementing a low-carbohydrate plan for a patient with type 2 diabetes in the documentary The Magic Pill. We believe food can be used as medicine. Many of our patients with insulin resistance, diabetes, metabolic syndrome, PCOS and more will see excellent results and resolution of chronic disease states with low-carbohydrate diets. Education and understanding as to which dietary strategy is best for the individual is essential in reclaiming one’s health. There is no doubt in my mind that low-carbohydrate planning can be extremely useful and safe for the appropriate clinical scenario.”

Colin C

“I treat patients with cancer, specializing in breast cancer. I also perform clinical research on the interactions between diet, cancer, and exercise, and advise my patients on the benefits of a healthy lifestyle for helping to prevent and reduce the risk of cancer by promoting a healthy metabolism. These recommendations include a general reduction in carbohydrates, including low-carbohydrate and ketogenic diets, based on the available literature that supports this approach. I also recommend that patients take control of their own health by educating themselves with sources that provide evidence-based recommendations and scientific reviews.”

Robert C

“As a bariatric surgeon and as a researcher studying the liver for two decades, my research has shown that it is the toxicity of chronic excessive carbohydrate consumption that is the primary cause of obesity and obesity-related co-morbidities. As an obese doctor myself, I was able to lose 90 pounds once I recognized that I had a carbohydrate addiction and so eliminated carbohydrates from my diet. While I have performed more than 8,000 bariatric surgeries, I firmly believe that surgery is only a tool. Obesity and diabetes are not treated by surgery, but rather by the journey to become carbohydrate-free.”

“As a family physician in the most obese state in the USA, I see the devastation of type 2 diabetes and metabolic disease in almost every hospital patient I see. For six years, I have been using education and a low-carb lifestyle to help these patients get healthier, reduce meds, gain energy, and lose belly fat. They learn that this is a sustainable life plan filled with joy and good food. Every day I share the amazing resource of Diet Doctor in my practice. Together as a global community we can put these conditions in remission and prevent them all together.”

Ignacio C

“In my psychiatric practice, the high rate of obesity and metabolic disorders among my patients prompted me to develop an integrative therapeutic response, especially to address frequent patterns of impulsivity/compulsivity, low energy/lethargy, mood instability, mental fog, poor concentration and cognitive deterioration. A real-food, low-carb, healthy-fat, often ketogenic lifestyle, combined with intermittent fasting, stress management, rest, and movement — and appropriate pharmacotherapy as needed — results in improved general health, cognitive function, mood management, and quality of life. Diet Doctor, especially the new Spanish site, is a great tool for my patients.”

“The mission of Diet Doctor says it all: Make low carb and keto simple. For over a decade the website has been an invaluable resource for evidence-based nutritional advice and support for anyone seeking to lose weight and improve health with diet. And the results speak for themselves. By building a nutritional safe harbor, available to anyone, anywhere, anytime, Dr. Eenfeldt and the Diet Doctor team have revolutionized the delivery of nutritional information for the greater good of a world that needs it desperately.”

“I prescribe ketogenic whole-foods diets because they are powerful metabolic interventions with the potential to address root causes of psychiatric disorders, including inflammation, oxidation, and insulin resistance. I enthusiastically recommend the Diet Doctor website to all my patients because it is the most comprehensive resource for low-carb news, advice, science, inspiration and support in the world. The information there is trustworthy, easy to understand, available in multiple formats and languages, and funded entirely by the people.”

Jeffry Gerber

“As a physician I was frustrated and distressed by patients’ worsening health and by the spiraling health care costs caused by diabetes, obesity and other chronic conditions, all linked to the food we eat. We help our patients improve their health and optimize their weight with prescribed lifestyle modification, teaching them the link between unhealthy, refined and processed foods and chronic illness. Our growing database of patients who have lost weight and improved cardio-metabolic markers demonstrates the benefits of low-carbohydrate, whole-food diets. In short, reducing the carbohydrate content of our meals controls hunger, promotes weight loss, and improves health.”

“I recommend low-carb and keto diets because there’s nothing more fun than empowering people to treat the root of the problem to help regain their health. Diet Doctor offers a great deal of support to me and to my patients because it allows them to digest the information in their own time and, particularly if it’s the first time they hear it, it helps ease their fears to see that there’s a whole world of science supporting the new prescription (food) I am giving them.”

“As a board certified physician practicing internal and obesity medicine, I reclaimed my health and lost over 150 pounds by ignoring conventional medical advice. I now focus on diabetes, hypertension and lipid management through lifestyle and dietary modifications whenever possible. As well as seeing patients in my clinic, I provide remote consultations via tele-medicine software and equipment, utilizing remotely-tracked bio-impedance scales, blood pressure cuffs and continuous glucose monitoring devices.”

“I have been working as an internal medicine doctor and diabetologist for over 20 years, focusing on gestational diabetes mellitus (GDM), and also teaching future doctors and nutritionists. In 2016, we corrected our official dietary guidelines for GDM, removing the minimum recommended intake of carbohydrates and setting a maximum at 200 grams a day, with low-carbohydrate diets as an option. I would like to thank GDM dietitian Lily Nichols, Dr. Andreas Eenfeldt at Diet Doctor and the entire LCHF community for improving outcomes of Czech women with GDM and other patients with type 1 and type 2 diabetes or metabolic syndrome.”

“Real food — that is low-sugar, high-fiber — works for most of the population, but some patients may need a low-carb diet for best results. For those patients, I am totally for low carb. I have certainly had many insulin-resistant patients who didn’t get better until they went on a low-carb diet. I am not remotely concerned about negative effects of low carb. I feel that, aside from patients with familial hypercholesterolemia and type 5 hyperlipidemia, a low-carb diet is entirely safe.”

Dr. Aseem Malhotra, MD

“The totality of evidence is very clear: A low-carbohydrate dietary approach is the most effective way to manage the insulin resistance syndrome which is that single biggest driver of obesity, type 2 diabetes and cardiovascular disease. Diet Doctor has been instrumental in providing extremely useful, clear and educational material to all who want to implement this dietary approach in to their lives. That’s why I recommend the website to all my at-risk patients.”

Paul M

“I recommend low-carbohydrate and ketogenic diets to almost all my patients, from the general public to world-class Olympic athletes. A huge variety of benefits can be seen, from improvements in metabolic health and reductions in joint pains to enhanced athletic performance. While a degree of nuance is needed for specific recommendations, based on factors like general health and goals, the general principle is to reduce carbohydrates while ensuring appropriate intake of fat and protein. This addresses the key problem of insulin resistance, which is central to many modern disease states, including cardiovascular disease and type 2 diabetes.”

Leena M

“As an interventional pain physician, in addition to cutting-edge techniques I use nutritional strategies to deliver people from a cycle of pain and disability. Chronic pain may result from inflammation and metabolic disarray; it intersects every part of life and is an illness as much as it is a symptom. Obesity and aging are inflammatory processes at the root of many pain-inducing chronic diseases. I suggest anti-inflammatory, low-carb, ketogenic diets and fasting protocols to optimize patients’ health. Diet Doctor is a great resource for patients compliant with this lifestyle.”

“I have been a UK family doctor since 1990, and discovered the low-carb and keto ways of life in 2014. Until then, I had never seen a way of eating that resulted in normal weight and improvements in other health problems like diabetes, epilepsy, arthritis, and asthma. When I discovered Diet Doctor I was very impressed, and loved the recipes. I now run low-carb courses for the public and health care professionals.”

Katharine M

“I am a family physician and co-author of the book The Diabetes Diet. I have been advocating a low-carb diet for patients for the last 16 years — for weight loss weight, cardiac risk reduction, and better blood sugar control in type 1 and 2 diabetes. The diet enables patients with type 1 diabetes to reduce their insulin needs, while patients with type 2 diabetes on insulin may be able to eliminate the drug completely. I leave the choice as to whether the diet needs to be ketogenic or not up to patients, depending on their motivation and goals.”

Tim N

“In 2010 I came face-to-face with the compelling, robust evidence for the effectiveness of the low-carb, high-fat diet to prevent and treat serious diseases like diabetes, obesity and heart disease. It contradicted everything I knew as a doctor and scientist about optimal nutrition. I have since aimed to change medical dogma and foster respectful dialogue on evidence-based nutrition, but at a brutal personal and professional cost, even though eventually vindicated. The Noakes Foundation, since 2012, has been promoting unbiased nutritional research into the effects of LCHF on all aspects of human health. The sugar-free train is bound for glory.”

“By personalizing variations of low-carb or keto diets, with or without various types of fasting, my patients inspire others as they lose weight, feel better, and improve or even reverse disease and inflammation. There are many ways to individualize this way of life. Diet Doctor is a useful resource for patients and for other healthcare providers. Whether they are looking for some recipes and ideas for meals, a complete meal plan and shopping list for a two-week jump start, or they just want to keep learning more about low carb, keto and intermittent fasting, they can find trustworthy useful answers.”

Chris P

“I have personally followed a low-carb, keto diet for over 20 years for my own health, and have used it for over 15 years with patients, primarily for weight loss. Recently, I have found the medical version of the ketogenic diet to have antipsychotic effects and mood benefits in patients with chronic mental illness, so I am pioneering the clinical use of the ketogenic diet in psychiatry. I often recommend Diet Doctor to patients, friends, and family as a trustworthy resource for weight loss versions of the diet. For the treatment of serious mental illness, I recommend working with a trained clinician.”

Blair O

“As an interventional cardiologist for 30 years —and an avid runner and active person — I realized as I aged that eating less and moving more did not work for me or for my patients. The ketogenic diet resulted in a 30-pound weight loss and a dramatic increase in energy. As a past president of the Canadian Cardiovascular Society, I have been urged by medical colleagues to share my ketogenic knowledge widely. With my wife, a certified health coach, I have established a cardiometabolic clinic for obesity and insulin resistance syndromes. One of the resources we recommend is Diet Doctor.”

“At the Norwood Surgery in the North of England we have been offering a low-carb option for our patients with type 2 diabetes since 2013. We feel this makes perfect sense in a condition which could be seen as one where sugar is acting as a ‘metabolic poison’, remembering that starchy carbs like bread rice or breakfast cereals digest down into surprising amounts of sugar, as predicted for us by the glycemic index.”

“When the low-fat dietary advice I had been preaching for decades didn’t work for me in middle age, I changed to low-carb. After mentorship from Dr. Eric Westman, I introduced low-carb to my patients with astonishing results reversing diseases I had only been “managing”. In fact, more than 90% of patients who come to me on insulin are able to come off. I run a multidisciplinary medical weight loss clinic helping to restore health. This has brought the joy back into medicine for me. Diet Doctor has been an amazing resource to help me and my patients in this journey.”

“At the Duke Diet and Fitness Center, our residential clients can choose from three levels of carb intake that happen to be aligned with the Diet Doctor’s levels of liberal low-carb, moderate low-carb and keto low-carb. The alignment is not by chance, however. It’s because we have separately come to the same conclusions after carefully and objectively reviewing the evidence and gathering information from experienced clinicians and patients. The Diet Doctor website is very unique in that regard, and a great resource for our patients!”
