Linus Mårtensson, MD


I managed to completely reverse my own gut related health issues with a low carb diet and intermittent fasting. Since then low carb diets have been the basis for my work with most patients as a family physician and with all my patients working as a doctor in functional medicine. I make it a point to ask all my patients how and what they eat since it’s at the root of so many of our modern chronic diseases and ailments. Since the start, I have been a fond reader and proponent of Diet Doctor and I still recommend it daily to both patients, friends and family as a great source for free and unbound information related to diet.
