The friend of Greyson Lopez just wanted to be kicked out of the military because of being too chubby, it was the end of 2017, and Lopez noticed that his friend started losing weight – fast. "He lost 20 pounds in 20 days," says Lopez, 23, who works for the Navy in IT. "So I asked," How did you do that? ""  In search of a plan that is not going so fast, the rapidly developing, less fat guy explained, he went to Reddit, where he found a thread about the "ketogenic diet". A strong keto subreddit report on the loss of 52 pounds in as many days, not the feeling of being hungry and even better able to concentrate, however, to say the least, the diet was as contrary to the American one Politics "Shared".
First, you eat very limited carbohydrates. Low carb is not radical, but ketogen is extremely low: less than 50 grams per day. (The average American meets with breakfast.) Fruits are mostly no, and you have to keep vegetables tight. Yes, vegetables
Next you are limited to at most 100 grams of protein per day, a muscle-building nutrient that is absorbed by almost every other diet. What is left? Fat. Much of it: Marbled steak, greasy fish, eggs and bacon. Top with butter, olive oil and lard. A classic keto diet consists of 90 percent calories from fat, 6 percent from protein and 4 percent from carbohydrates. The diet is indeed a huge FU for the food pyramid.
But Lopez & # 39; s friend said the crazy diet is scientifically justified: The lack of carbohydrates and the excess of fat pushes your body into a biological state called ketosis. Meanwhile you burn fat instead of glucose. Lopez – who was five feet nine, 200 pounds, and "a bit portly" – was intrigued. His online digging led to the podcast Joe Rogan Experience . Rogan, a college drop-out and self-described "Dumb Slut," unpacks complex topics without presumption. He interviewed leading keto researcher Dom D & # 39; Agostino, a professor of physiology at the University of South Florida.
" It was interesting to hear a scientist about it Talked about what he eats and why, "says Lopez. D & Agostino is not a salesman, and he did not do the diet, which raises the question: who did that? Then things get weird, it's about a two-time criminal, medical misconduct, and several deaths, but Lopez did not know the story of Keto, just wanted to find out if the hype was real. "I threw away all my carbohydrate-rich foods like ramen and hot pockets," she says "Then I grabbed so much bacon, grass-fed butter and steak, I could find.
WHAT makes a diet tip? Adrienne Rose Bitar, Ph.D., nutrition historian at Cornell University, has spent this question on her career. "Most diets start with some dissatisfaction we have with our lives and our bodies," she says. Then you need a simple, engaging message that resonates at the right time and in the right place, blaming a culprit for your dissatisfaction. Low fat diet: fat is bad; Do not eat fat. Paleo: Processed foods are bad; eat only pre-industrial foods like a caveman. With keto, you do exactly what your doctor (and your mother) told you not to eat: eating fat and skipping vegetables. While this partly explains the rise of keto, it overlooks a critical aspect. It turned out that the keto diet was not designed to lose weight.
Fasting has been used to treat epilepsy since 500 BC Your body is usually fed with sugars made from carbohydrates you eat Your body burns it in about 48 hours, and then an evolutionary survival mechanism sets in. Your body switches to its stored fat, which can be some of it Registration of 0.5 to 5 millimoles of ketones per liter of blood.) In the early 1920s, Wildcourse Doctor Dr. Russell Wilder started on a fat-centered diet He mimicked the effects of fasting by depleting the body of sugar and tested its "ketogenic" diet in people with epilepsy Since then, it has been an effective treatment for seizures.
Weight loss came to the fore in 1972 when Robert Atkins, M. D., his first diet book published. The first weeks of his diet of the same name focused on the consumption of fat and very few carbohydrates to induce ketosis, a "happy state." , , [in which] Your fat is burned with maximum efficiency and minimal deprivation. "Thus, Keto was paced on the radar of Stephen
Phinney, Ph.D., an MIT-trained nutritional biochemist, who researched this route for eating endurance sports.
Then in 1976 a keto-si The so-called last-chance diet prevailed out of the rule : You drink a fat and protein rich mix until you lose your desired weight.The creator of the diet, the osteopath Robert Linn, DO, sold his $ 40 million worth of elixir but you should also have the supervision of a doctor, Few people did this body can not perform certain functions, such as sending electrical impulses to their heart, which resulted in the Last Chance diet killing at least 60% of the time Among the consequences were new regulations, a negligent lawsuit against Dr. Linn and Phinney, and his research into the prohibition of ketosis in academic Siberia.
Phinney, however, continued to evolve and lead For example, studies have shown that liquid ketogenic diets with sufficient minerals do not cause heart problems. In 1988 Optifast was born. As with the Last Chance diet, it was a fluid diet, but with enough vitamins and minerals and a celebrity: Oprah Winfrey. "She did it for four months," says Phinney. "One day she opened her show and pulled out a red car containing 67 pounds of pork and beef fat. And she points to it and says, "I've lost so much weight." The Oprah effect was soon fully effective: Optifast
immediately received more than 200,000 inquiries and keto research increased in the early 1990s.
At that time the diet was adopted by the hardcore bodybuilding underground." I first heard about this guy named Dan Duchaine, "says D & # Agostino, as well as a handful of other important nutritionists interviewed for this story, Duchaine, who died in 2000, was a double offender advocating the steroid movement of the 1990s and, yes, reviving the keto as a possibility For bodybuilders, quickly reducing fat for the competition – and with the rediscovery of the Atkins Diet in the 2000s, new generations of Americans are warming up to the idea that low carb could be a safe diet tool.
The Scaling by Keto begins with a study published in Science in January 2013. Scientists at the Gladstone Institute, a base in San Francisco In a research It has been reported that strong antioxidant and anti-inflammatory genes are activated by beta-hydroxybutyrate, a ketone body produced by restricting calories or carbohydrates. The keto diet, as stated in the press release, "could slow down the aging process and one day enable scientists to better treat or prevent age-related diseases such as heart disease, Alzheimer's and many cancers." Dietally, biohackers aroused interest in keto for fat loss , athletic performance, productivity and longevity in equal parts – began to experiment itself.
Among them was Tim Ferriss, the Princeton-trained podcaster in Silicon Valley and author of The 4-Hour Work Week . He had messed with keto and wrote that it was "incredible for simultaneous fat loss and lean muscle growth, although it may be unnecessarily complicated for non-athletes." In 2013, he posted a video on his blog by Peter Attia, a longevity expert. Dr. Attia talked about his struggle with the metabolic syndrome and how Keto has changed body and health in ways that movement and vegetables could not. He showed diagram by diagram, showing the positive influence of keto on its triglycerides, cholesterol and blood sugar levels.
Ferriss & # 39; a million monthly followers, people obsessed with data The diets were traditionally religious: halal, kosher, fasting. "Many diets were actually plans to cleanse the soul – and an unclean soul meant that one could go into the Hell could go. "Bitar says." However, lately, nutrition has become a means of creating an optimized self. "Instead of dogma, you have data, and the number of people searching for the keto diet doubled immediately and continued to increase, as did other lifestyle gurus, like Dave Asprey and Mark Sisson, who crashed aboard.
If the diet is considered safe, if done properly, the emphasis on saturated fat and lack of nutrients can affect heart health over time. "We still have not enough evidence of what happens to your body after ten years of ketosis, "says Dr. Stephan Guyenet, nutritionist and author of The Hungry Brain.
Ketos's other benefits – reduced hunger and heightened focus – were aroused the biohacker brothers. "Keto controls hunger," Guyenet says, "The driver could be the extreme nature of the diet." Carbohydrates and fat together stimulate the release dopamine and activate motivating circuitry in the brain that drives us to eat, "he says. Consider Ice Cream: It's just so appetizing because it's sweet and fat. As for the mental clarity to which many advocates swear? Controversial. Each effect is probably due to the fact that less junk food is eaten, which can lead to a roller coaster effect and influence the mood, says dr. Nicole Avena, neuroscientist at Mount Sinai in New York City.
However, there are people for whom Keto offers unique benefits: Type 2 diabetics, according to a recent study by Phinney Those who followed a ketogenic diet and received diet advice for one year significantly reduced the consumption of diabetes medications and lost an average of 30 pounds.
Thanks to the Internet phone effect, claims to keto greater Google News came first : On November 3, 2015, Ferriss broadcast a podcast with D & # 39; Agostino: "This is the turning point when diet gets into the country's language and zeitgeist," says Andy Galpin, Ph. D., a human
Performance researcher at California State University, Fullerton.
The title of the episode e: " D 'Dom Agostino on fasting, ketosis and the end of cancer."
Ferriss told d The story of a friend with testicular cancer, who wanted to fast for three days and previously in the ketosis chemotherapy. D & # 39; Agostino noted that every cancer patient needs medical monitoring of his diet, but he also said, "If you put your physiology in a state of fasting ketosis, cancer cells that are highly dependent on survival and growth become tremendously metabolic stress exposed to glucose and insulin levels. By deducting from these growth needs, they can [die] and you could possibly move away from some precancerous cells. When asked about this quote, D & # 39; Agostino says, "The title of the episode is unfortunate," but he points out his research indicates that keto can slow down the progression of some cancers, but accelerates others. "It's a lot more complicated than starving your sugar cancer," he says (Ferriss declined to be interviewed for this article.)
