I ate a lot of bacon, cheese, eggs and meat (steak and chicken mostly). For a person whose eating philosophy is typically more plant-based and whole-food-focused, eating processed pork products every morning took a lot of personal persuasion. It also took a complete mental shift, because eating multiple pieces of bacon every day for weeks on end goes against everything I've been taught for personal health.

For the second four weeks, they were fed a very-low-carbohydrate, low-sugar ketogenic diet. Five percent of their total calories came from carbohydrate (36g per day), and 2% of their total calories came from sugar. 15% percent of the calories came from protein. The keto diet totaled 2,738 calories per day. Note that the caloric intakes were kept close to identical, meaning fat loss could only be attributed to the source of the food rather than its caloric content.
The insulin theory of obesity, in short, declares that the primary cause of obesity is higher carbohydrate diets because these diets increase insulin secretion more than any other diet. When insulin levels are high, fat storage will increase significantly and “starve” muscles and organs of energy. This causes increased hunger and overeating that results in obesity.
“The growing scientific evidence is robust that the low-carb, ketogenic diet is safe and effective, especially for the management and reversal of type 2 diabetes and for weight loss. I believe that millions of people in the world might have their health improve by adopting this way of eating. Together with the growing team at Diet Doctor we aim to make low carb simple and to empower people, everywhere, to revolutionize their health. Having so many respected low-carb doctors join this page helps spread the word about this potentially life-changing way of eating.”
Once your body adapts to using fat for fuel (can take anywhere from a couple of weeks to over a month) you'll find your apetite changes and it's very easy to eat very low calorie - you won't feel hungry as often and you'll have an easier time recognizing when you should stop eating. A lot of people on keto naturally fall in to some sort of intermittent fasting (eating only 1, 4, 6 or 8 hours of the day and fasting the rest) because they just aren't hungry.
Boosts energy levels. The sluggishness and lethargy you feel after a heavy carb-filled meal is due to the insulin spike and reactive sharp drop in blood sugars. Eating a high-fat diet provides steady energy and helps you avoid crashes that are associated with eating a high-carb diet. Additionally, since ketones are the brain’s preferred source of energy, a ketogenic diet leaves you feeling more alert and mentally energized without having to supply a steady stream of caloric intake .
“I am determined to shatter the chiding “eat less, exercise more” obesity medicine paradigm. Obesity is not a personal failure, but a chronic health condition unfolding in our country and around the world. It is a result of the “carboholic” society we live in. Through a holistic approach, I arm patients with knowledge, tools, and skills to manage their weight as well as their overall health.”
“As a full-spectrum family physician since 2004, luckily I stumbled on the wonderful low-carb community two years ago after my amazing wife was forced to make dietary changes after surgery. I’ve never looked back! After transforming my own health, with help from resources like Diet Doctor, Jimmy Moore, and Dr. Jason Fung, I’ve committed to bettering the lives of my patients with intensive dietary management through LCHF and intermittent fasting. Empowering patients to make these lifestyle changes has truly brought back the joy of medicine for me. I am so thankful to all who have inspired me along the way.”
“I have been a supporter of a low-carb lifestyle that includes intermittent fasting for myself and my patients for years. I am part of our health systems Medicine Residency program. I teach physicians-in-training and medical staff to utilize low-carb and keto dieting to improve the health of their patients and reduce their need for medications. Diet Doctor is an excellent resource for patients and physicians to help patients help themselves to promote a healthy lifestyle.”
One thing many people love about keto diet meal plans is that tracking your food is optional. "One of the biggest benefits of the ketogenic diet is that there's no need to meticulously track your calories like you may in other diets," notes Dr. Josh Axe, D.N.M., C.N.S., D.C., founder of DrAxe.com, best-selling author of Eat Dirt, and cofounder of Ancient Nutrition. "Because you're filling up on fat and protein, you're more likely to feel satisfied and energized all day long, which causes you to naturally eat less." This isn't to say that food tracking on keto is discouraged. "Some people may find calorie counting a useful tool to be more mindful and aware of what they're eating, but it's not necessary on the ketogenic diet," says Dr. Axe, but there's no need to get too stressed about hitting a certain caloric goal, especially if you're not trying to lose weight.

The average daily goal for keto is 20 grams of net carbs. Net carbs are the total carbs in a given serving of food, minus the carbohydrates that are supplied by fiber. You’ll find carb grams quickly add up, even when you’re choosing the best low-carb foods, like spinach and avocado. Keeping your body in a quasi-keto state can be hard on you, warns Santo: “This will leave you feeling sluggish, foggy, and discouraged,” he says. “It will most likely cause a weight plateau, and maybe even weight gain.” Here’s what it’s really like to be on a keto diet.
