“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 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.”

“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.”

“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.”

“I have been staying informed about therapeutic nutrition, diabetes reversal, and the role of diet in optimal metabolic health, and I am also practicing a low-carbohydrate diet. I do not believe in a one-size-fits-all approach to diet; what works for one person may not work for another. As a physician, I am very interested in the possibilities that good nutrition can bring to lifelong health.”

“As a reproductive endocrinologist, I have been studying nutrition and fertility for over 15 years. I advise all my patients, both women and men, to adopt a low-carb ketogenic diet both prior to pregnancy to improve their fertility and during pregnancy to improve fetal and maternal health. This way of eating has been shown repeatedly in my practice to improve all measures of health for women and men. We refer all our patients to Diet Doctor which in our opinion is the best online resource for our patients to find all the information, recipes and meal plans they need to be successful.”

“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 recommend a high-fat, low-protein, ultra-low to no-carbohydrate diet with intermittent fasting to my fertility patients. Immunologic dysfunction can contribute to recurrent pregnancy loss and infertility. One of the easiest ways to improve immunologic function is to reduce inflammation throughout the body. The keto diet does this. I use Diet Doctor myself and recommend it to patients as a valuable resource.”

Hana K

“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.”

“I am a medical practitioner who has type 1 diabetes. Since adopting a very low-carb lifestyle I have found that day-to-day diabetes management has become so much easier with the added bonus of normal HbA1c. As a result of smaller insulin doses, I am not tied down to strict meal times and can eat when I choose. Similarly, glucose control with exercise is far more predictable. Very low carb for me gives as near to a ‘normal’ life as someone with diabetes can get.”

“I am a physician with type 1 diabetes. I have been using a low-carb, ketogenic diet to treat my own diabetes for the past 16 years. Evidence shows that low-carb diets are safe and effective. With the potential to reverse type 2 diabetes, control type 1 diabetes and even stop, slow down, or reverse complications, a low-carb diet can be life changing. Diet Doctor provides the most accurate and relevant materials for a healthy, easy and fun low-carb experience.”

“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.”

“After years of practicing Family & Sports Medicine, I’ve recognized that preventing and addressing my patients’ dietary metabolic issues are the foundation upon which quality medical and musculoskeletal care are built. LCHF principles produced such remarkable results in my patients that I completely redefined my scope of practice and developed a unique Lifestyle Medicine Program that synergistically complements my Sports Medicine & Non-Surgical Orthopedics specialty practice. I truly care for the whole person. Diet Doctor is an exceptional, comprehensive resource for lay persons and clinicians; I recommend it to all my patients and colleagues.”

“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.”

“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. “

“I’ve studied LCHF nutrition for over 20 years for personal health benefits. In my medical practice, it has become integral to reversing many of modern society’s worst medical concerns including metabolic syndrome, obesity, and diabetes. It can be applied safely and effectively for nearly all of my patients and often results in dramatic restoration of good health.”

“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.”

“As a family physician, I have been treating patients with low-carb and keto diets since 2013. I have seen these diets consistently produce remarkable results for numerous medical conditions, especially type 1 and 2 diabetes, obesity, fatty liver, IBS, PCOS, GERD, asthma, hypertension, migraines, coronary artery disease, and dyslipidemia. I can’t count the times that my patients are able to get off multiple medications after implementing a low-carb diet; the most common remark I hear is that they just overall feel better! I recommend my patients to Diet Doctor daily.”

“As a physician who developed type 1 diabetes in 1998 at the age of 38, I struggled to manage my blood sugar with conventional medical advice. I met Dr. Andreas Eenfeldt at a medical meeting in 2012 and have used Diet Doctor as an excellent source of information for both myself and my patients ever since. The low-carb diet resulted in a marked improvement in my blood sugar control and my entire outlook on life. I provide online coaching to people with diabetes who need individualized attention.”

Roshani S

“As an American board-certified endocrinologist who moved back to Mumbai, I saw India’s diabetes epidemic and dogma through a different lens. Low carb plus intermittent fasting has proven very effective in the reversal of insulin resistance, fatty liver, PCOS, reduced fertility, obesity, metabolic syndrome, hypertension and even early diabetic neuropathy and nephropathy. I conduct Diabetes Self-Management classes every month while looking at the whole lifestyle: stress, sleep, exercise, mindfulness, self-care and nutrition. This works even in India’s predominantly vegetarian culture! I often refer patients to DietDoctor for low-carb recipes and FAQ’s.”

“I recommend low-carb nutrition for the majority of my patients and clients. And I send them all to Diet Doctor for the best recipes, instructional videos and written guides for everything someone needs to get started and to thrive on a low-carb lifestyle. Diet Doctor doesn’t have anything to sell you; its only goal is to provide you with the highest quality, evidence-based information to help you improve your life. That is hard to find in today’s ad-driven and product-driven internet. In fact, I loved Diet Doctor so much, I decide to work for them hosting their podcast!”

“I am a hospitalist/primary care doctor and also a specialist in obesity. As I see it, nutrition and other lifestyle factors are at the root of most of the diseases I treat. My own health issues corrected with LCHF. I went on to recommend LCHF to my patients, who have since experienced a wide variety of improved outcomes. Face-to-face time with patients is frustratingly short so simply writing “” on slip of paper and handing it to patients is a great way to set them in the direction of trustworthy diet information.”

“Are you struggling to stay off sugar and flour? Addiction to these, and other trigger foods is real. The processed food industry has engineered food to be as addictive as alcohol, tobacco and even cocaine.
As an addiction specialist, I recommend Diet Doctor as a resource for my patients, many of whom are addicted to sugar. Diet Doctor offers recipes that are delicious and remove the addictive elements from food. I encourage high-fat and low-carb food plans only – because they work: You can lose weight, keep it off and be free from food obsession. Freedom tastes great!”

“Diabetes and metabolic syndrome are rampant in my community, so I prescribe a very low-carb, high-fat diet to many of my patients. This way of eating has resulted in many successes, such as stopping or reduce my patients’ medications. I have spread the LCHF word by giving lectures to our doctors and nutritionists. As a result, a ketogenic diet nutritionist in our organization now gives classes to patients and our endocrinologist is also on board. I give out Diet Doctor information to almost all my patients and it is truly a big resource in my practice.”

“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.”

“I discovered the ketogenic diet in 2017 and since then I have come to truly believe it is the metabolic and nutritional pathway to overall health. Hippocrates once stated, ‘All disease begins in the gut” and I now truly believe the right food can cure. I am now discouraging patients from undergoing bariatric surgery too soon and advising them to try the keto diet first. Diet Doctor gives people the knowledge they need. It is a place where everyone can go to learn and have fun with this nutritional approach.”

“As a pediatrician practicing for the past 24 years, I spend most of my clinical time caring for children with chronic behavioral, developmental, psychological or metabolic conditions (ADHD, depression, anxiety, OCD, Tourette’s Syndrome, autism, autoimmune disease, obesity, NAFLD, etc.). A well-planned, low-carbohydrate (and in many cases ketogenic) nutrition plan is a very powerful tool that I use with my patients to address both physical and mental health. I so appreciate Diet Doctor and reference it frequently for my patients as the best resource for this topic. This site is commercial free, well-supported, referenced and frequently updated.”

“I recommend LCHF nutrition to all my patients to shift their metabolism to a more beneficial state. This nutrition is often enough to reverse diseases like obesity, diabetes and fatty liver disease, improving the health and quality of life of my patients.

I recommend the Diet Doctor website, due to its panel of experts, to all my patients to make their transition easier.”
