The truth behind the world's most cutting- edge, fat- burning performance meal plan: the keto diet. Timothy Noakes, M. D., is an emeritus professor in the Division of Exercise Science and Sports Medicine at the University of Cape Town. While his name may not ring a bell here in the U. S., he’s a full- blown celebrity in his native South Africa and one of the most accomplished exercise physiologists on the planet. You can’t walk by a restaurant in Cape Town that doesn’t offer a “Noakes option”—say, an avocado stuffed with breakfast sausage and eggs, or a double cheeseburger with lettuce sans bun—and evidence of his teachings seems to be everywhere, mostly in the form of the nation’s best- known athletes, including ageless golfing legend Gary Player and eight- time Ironman World Champion Paula Newby- Fraser. In fact, Noakes’ celebrity these days is such that he’s even been pulled into South African presidential politics: To echo the country’s papers of record, “Is President Jacob Zuma’s and his wife’s dramatic weight loss a result of the Noakes Diet?” No one is sure about the president, but his wife, definitely: She’s lost 6. Noakes plan. To high- performing athletes, Noakes preaches that the bedrock tenet of endurance athletic nutrition—that winning performance is best fueled by eating lots of carbohydrates—is simply wrong. Instead, he believes athletes can alter their bodies so that their metabolism burns fat as a primary fuel source, a physiological process known as ketosis, either from stored body fat or from the foods they eat every day. For non- athletes and anyone trying to lose weight or keep it off, Noakes’ advice is that eating a high- fat diet, with few if any refined carbs and as little sugar as possible, will switch on the same fat- burning system and keep your body lean and your weight stable without making you hungry. According to Noakes and a growing number of nutritionists, physiologists, and biohackers, when you’re in a state of ketosis—best attained through a strict “ketogenic diet”—good things happen. Sometimes, amazingly good things. Two years ago, Le. Bron James famously lost 2. Tim Ferriss, the author of the Four- Hour self- improvement book series, followed a strict keto diet to cure his Lyme disease, and performs a long multi- day fast every four months as a means, he says, of pushing ketosis further and starving incipient pre- cancerous cells of sugar (more on that later). Last summer, Sami Inkinen, the ultrafit co- founder of real estate juggernaut Trulia, rowed with his wife from California to Hawaii in record time on a keto diet, to promote high- fat eating and raise awareness about the dangers of too much sugar. The Keto Diet, say its ardent supporters, is a natural way to literally reprogram your metabolism and transition to an upgraded operating system. You’ll ultimately feel better and perform better, and your body fat will plummet. But this sort of “low- carbohydrate, high- fat” (LCHF) diet, as Noakes calls it, is still far from mainstream. It takes serious dedication to drop your daily total carb intake to below 5. The USDA Dietary Guidelines were just changed in January to mention the need to limit intake of added sugars and refined carbs like bread, rice, pasta, cookies, and crackers, which spike blood sugar more rapidly than candy. Check the label of nearly any sports drink, and it’s most likely loaded with natural or added sugar. Go to the grocery store today and the labels are awash with the message of “low fat,” “no fat,” or “zero fat.”Meanwhile, Noakes continues preaching that the right kinds of fats—the ones our bodies evolved to process, like animal fat and butter, olive and coconut oil (but not vegetable oils like corn oil and soybean oil)—are extremely healthy. Noakes titled his 2. Challenging Beliefs, and, at age 6. Twitter account, @Prof. Tim. Noakes, where he chimes in every few hours and has churned out more than 2. Noakes constantly retweets the latest nutrition stories and offers his own food for thought: “Consumption of refined grains, sweets and desserts, sugared drinks, and deep- fried foods = more heart disease” or “Truth wins in the end. But it takes time.”The healthy ultramarathoner who defied the odds—by becoming diabetic. Noakes’s war on sugar goes back a generation, to when his father developed type- 2 diabetes. Type- 2 is a disease in which the body gradually loses its ability to regulate blood sugar through the production of the hormone insulin. It’s linked to genetics, but also to diet—particularly sugar and refined carbs—as well as obesity and inactivity. Diabetes experts estimate that the disease speeds up the aging process by roughly a third, damaging the body from the inside out. Too much blood sugar slowly destroys blood vessels, with results ranging from mild—early wrinkling of skin—to catastrophic: heart disease, blindness, stroke, amputations due to poor circulation, and even Alzheimer’s disease (more on that later). Noakes’ father eventually died from type- 2, but because Noakes himself followed a low- fat diet, exercised regularly (he’s run upward of 7. To be sure, as he got older he put on some weight, and his energy sagged, but he was in good shape. Regardless, in 2. Noakes was diagnosed with type- 2 diabetes. Though he didn’t know it yet, a lifetime of well- intentioned carbo- loading for his athletic endeavors had set him up for a fall. Not long after he got the news, he happened to receive an e- mail about a book title The New Atkins for a New You, and realized he recognized many of the authors’ names on the cover, which belonged to respected exercise experts Stephen Phinney, M. D., Ph. D; Jeff Volek, Ph. D., R. D.; and Eric Westman, M. D. They argued that the late Dr. Robert Atkins, who famously promoted a low- carb, high- fat diet in the 1. The professors backed up their position with more than 5. Noakes says he learned more about nutrition that year than in his previous 4. I was 2. 22 pounds when I picked up that book,” he tells me. I’ve achieved my high school weight and my old running times.”His new way of eating, he says, also cured his migraines and acid reflux. On top of that, it eliminated spikes in blood sugar, kept his appetite in check, and allowed his body to burn its own fat as fuel. After Noakes’ diabetes had reversed course, he wrote about it for Discovery Health News; that triggered a national debate across South Africa, a country plagued by an epidemic of diabetes and its associated conditions. It’s especially resonated in the biohacker community of Silicon Valley. From an evolutionary standpoint, ketones—molecules formed by the breakdown of stored fat—are a very important fuel. And ketosis, the process by which the body uses those fuels, is essential for survival. Here’s how it works: The body—even that of a very lean athlete— stores about 4. When those carbs have been depleted, the body taps its fat stores for energy. The same is true for athletes who “bonk” during exercise—it’s because they’ve used up all their stored carbs. To go on, they must either eat more carbs (to burn as sugar) or start burning fat. When marathoners break through the so- called “wall” late in a race, they’ve begun to burn fat. Thanks to Noakes and other Keto Diet supporters, a growing number of athletes today prefer to be in that state at all times. Once they make the switch, they say, not only are their race results and game- day performances better, they report sustained energy, better moods, and clearer thinking. But it’s difficult, and most of us don’t really know what ketosis is like. The average American today is what nutritionists call “a sugar burner.” We ingest carbs for breakfast, so our blood sugar goes up quickly then comes crashing down before lunch, when we get our next carb fix. The process happens over and over again without our bodies entering ketosis. But getting your body to enter full ketosis is no small feat. Imagine forgoing all starchy vegetables, breads, sugary drinks (including fruit juice), pasta—essentially everything that isn’t meat or a non- starchy vegetable. It’s a tall order that only gets taller, because, once you’ve started the process, the body, feeling deprived, undergoes a transition phase often termed the “low- carb flu.” For a few weeks, physical and mental performance—at work, in the gym—dips noticeably and uncomfortably as the body tries to tap its missing fuel source. Not everyone sticks it out. There’s a shortcut to ketosis, however: fasting. If you don’t eat for many hours, your body will naturally go into fat- burning mode. There are many different fasting protocols to get into ketosis, but the most common is called intermittent fasting, which consists of not eating for 1. For instance, one can eat dinner at 8 p. Or, like Matt Mattson, Ph. D., chief of the Laboratory of Neurosciences at the National Institute on Aging, you can push it even further: Mattson regularly skips breakfast and lunch altogether. With no blood sugar spikes and crashes, just steady fat burning, he, like most intermittent fasters, feels mentally sharp and experiences little if any sense of deprivation. Keto: the official diet of Mars. But if all of this sounds like too much misery for you, consider another reason for going keto: Evidence shows that ketosis could not only help stave off Alzheimer’s but also help cure cancer. A few years ago, Dominic D’Agostino, a Ph. D. Military divers, he learned, use a device called a rebreather, which is silent and allows for extra- long dives— but, for reasons that are not yet fully understood, makes divers prone to unpredictable, life- threatening oxygen toxicity seizures. While looking for a way to treat these seizures, D’Agostino stumbled upon the Ketogenic Diet, which also happens to be a proven treatment for a possibly related malady: epileptic seizures in kids. D’Agostino believes the diet remedies a metabolism imbalance in which brain cells are starved of, or unable to process, glucose, causing the brain to go haywire. Dieting - Wikipedia. Dieting is the practice of eating food in a regulated and supervised fashion to decrease, maintain, or increase body weight. In other words, it is conscious control or restriction of the diet. A restricted diet is often used by those who are overweight or obese, sometimes in combination with physical exercise, to reduce body weight. Some people follow a diet to gain weight (usually in the form of muscle).
The Ultimate Cutting Diet – Devised By Pro Natural Bodybuilder Layne Norton. While I spend most of my time educating people about sustainable approaches to getting a lean, strong, healthy physique., I do have an interest in the extreme of body. Intermittent fasting diet for fat loss, muscle gain and health. Articles, research, diet advice, and free guides from IF-expert, Martin Berkhan. Diets can also be used to maintain a stable body weight and improve health. In particular, diets can be designed to prevent or treat diabetes. Diets to promote weight loss can be categorized as: low- fat, low- carbohydrate, low- calorie, very low calorie and more recently flexible dieting. In his 1. 86. 3 pamphlet, Letter on Corpulence, Addressed to the Public, he outlined the details of a particular low- carbohydrate, low- calorie diet that had led to his own dramatic weight loss. He himself was tremendously overweight and would constantly eat large quantities of rich food and drink. He began a meatless diet, taking only milk and vegetables, and soon regained his health. He began publicly recommending his diet for everyone suffering from obesity. In 1. 72. 4, he wrote An Essay of Health and Long Life, in which he advises exercise and fresh air and avoiding luxury foods. It described the benefits of a meat diet for those suffering from diabetes, basing this recommendation on Matthew Dobson's discovery of glycosuria in diabetes mellitus. In 1. 86. 3, he wrote a booklet called Letter on Corpulence, Addressed to the Public, which contained the particular plan for the diet he had successfully followed. His own diet was four meals per day, consisting of meat, greens, fruits, and dry wine. The emphasis was on avoiding sugar, sweet foods, starch, beer, milk and butter. Banting’s pamphlet was popular for years to come, and would be used as a model for modern diets. Atkins used the study to resolve his own overweight condition and went on to popularize the method in a series of books, starting with Dr. Atkins' Diet Revolution in 1. In his second book, Dr. Atkins' New Diet Revolution (1. Low- fat. Calorie consumption is reduced because less fat is consumed. Diets of this type include NCEP Step I and II. A meta- analysis of 1. Low- carbohydrate diets are sometimes ketogenic (i. Low- calorie. Some of the most commonly used low- calorie diets include DASH diet and Weight Watchers. The National Institutes of Health reviewed 3. They found that these diets lowered total body mass by 8% in the short term, over 3–1. Men should have at least 1,8. Very low- calorie. They subject the body to starvation and produce an average loss of 1. These diets are not recommended for general use as they are associated with adverse side effects such as loss of lean muscle mass, increased risks of gout, and electrolyte imbalances. People attempting these diets must be monitored closely by a physician to prevent complications. Many of these use herbs or celery and other juicy low- calorievegetables. Religious. The Daniel Fast resembles the vegan diet in that it excludes foods of animal origin. Examples include Lent in Christianity; Yom Kippur, Tisha B'av, Fast of Esther, Tzom Gedalia, the Seventeenth of Tamuz, and the Tenth of Tevet in Judaism. Eastern Orthodox Christians fast during specified fasting seasons of the year, which include not only the better- known Great Lent, but also fasts on every Wednesday and Friday (except on special holidays), together with extended fasting periods before Christmas (the Nativity Fast), after Easter (the Apostles Fast) and in early August (the Dormition Fast). Members of The Church of Jesus Christ of Latter- day Saints (Mormons) generally fast for 2. Sunday of each month. Like Muslims, they refrain from all drinking and eating unless they are children or are physically unable to fast. Fasting is also a feature of ascetic traditions in religions such as Hinduism and Buddhism. Mahayana traditions that follow the Brahma's Net Sutra may recommend that the laity fast . Members of the Baha'i Faith observe a Nineteen Day Fast from sunrise to sunset during March each year. Nutrition. They also agree on the importance of reducing salt intake because foods including snacks, biscuits, and bread already contain ocean- salt, contributing to an excess of salt daily intake. It offers a wide array of personalized options to help individuals make healthy food choices. It also provides advice on physical activity. It is important to know the amount of energy your body is using every day, so that your intake fits the needs of one's personal weight goal. Someone wanting to lose weight would want a smaller energy intake than what they put out. There is increasing research- based evidence that low- fat vegetarian diets consistently lead to healthy weight loss and management, a decrease in diabetic symptoms. The first source to which the body turns is glycogen (by glycogenolysis). Glycogen is a complex carbohydrate, 6. It is created from the excess of ingested macronutrients, mainly carbohydrates. When glycogen is nearly depleted, the body begins lipolysis, the mobilization and catabolism of fat stores for energy. In this process, fats, obtained from adipose tissue, or fat cells, are broken down into glycerol and fatty acids, which can be used to generate energy. The former include Weight Watchers and Peertrainer. The latter include Overeaters Anonymous and groups run by local organizations. These organizations' customs and practices differ widely. Some groups are modelled on twelve- step programs, while others are quite informal. Some groups advocate certain prepared foods or special menus, while others train dieters to make healthy choices from restaurant menus and while grocery- shopping and cooking. Food diary. A 2. 00. During prolonged fasting or very low calorie diets the reduction of blood glucose, the preferred energy source of the brain, causes the body to deplete its glycogen stores. Once glycogen is depleted the body begins to fuel the brain using ketones, while also metabolizing body protein (including but not limited to skeletal muscle) to be used to synthesize sugars for use as energy by the rest of the body. Most experts believe that a prolonged fast can lead to muscle wasting, although some dispute this. The use of short- term fasting, or various forms of intermittent fasting have been used as a form of dieting to circumvent this issue. While there are studies that show the health and medical benefits of weight loss, a study in 2. Finns over an 1. 8- year period showed that weight loss from dieting can result in increased mortality, while those who maintained their weight fared the best. The Nurses' Health Study, an observational cohort study, found that low carbohydrate diets based on vegetable sources of fat and protein are associated with less coronary heart disease. A long term study that monitored 4. Swedish women however suggests that a low carbohydrate- high protein diet, used on a regular basis and without consideration of the nature of carbohydrates or the source of proteins, is associated with increased risk of cardiovascular disease. A more recent meta- analysis that included randomized controlled trials published after the Cochrane review. These results can be understood because weight loss is mainly governed by daily caloric deficit and not by the particular foods eaten. The diet based around this research is called the Low GI diet. Low glycemic index foods, such as lentils, provide a slower, more consistent source of glucose to the bloodstream, thereby stimulating less insulin release than high glycemic index foods, such as white bread. Thus the authors concluded that the high- carbohydrate, low- glycemic index diet was the most favorable. A meta- analysis by the Cochrane Collaboration concluded that low glycemic index or low glycemic load diets led to more weight loss and better lipid profiles. However, the Cochrane Collaboration grouped low glycemic index and low glycemic load diets together and did not try to separate the effects of the load versus the index. Retrieved 2. 9 November 2.
