Jack Dorsey is a polarizing figure. Usually, the criticism is centered on how he manages Twitter. Last week, however, was different. Attention shifted from the usual tariff – the ever-present issues of right-handedness and harassment – to a whole new subject: Dorsey's unusual diet.
According to an article in CNBC, Dorsey follows a high caloric diet on weekdays, limiting herself to one meal, dinner.
The only meal of Dorsey is consumed between 18:30 and 21:00. It is an unequivocal case of low carb, which consists of a protein (usually chicken, steak or fish) and some green vegetables, such as salad, spinach, asparagus or Brussels sprouts. For dessert, Dorsey mixed berries or dark chocolate. Twitter and Square It is also said that its founder takes a glass of red wine on occasion.
CNBC According to the article, Dorsey sometimes took part in fasts over a weekend, consuming only water from Friday evening to Sunday evening.
It is also said that Dorsey goes to work on five miles (which takes him an hour and fifteen minutes), performs high intensity workouts on the days when he works at home (he uses the same name). Seven fitness app), and works standing up. office.
Protein and Pinotage
Eating just one meal a day is a bit extreme. It is almost certain that Dorsey suffers from a constant caloric deficit, since the average sedentary aged 31 to 50 (Jack Dorsey is 42) burns between 2,200 and 2,400 a day. Although low-calorie diets are beneficial in some cases (a study from Newcastle University showed that a diet strictly limited to 600 calories a day could type 2 diabetes), this is unlikely to be the case.
As a result of the CNBC article, many people have speculated that Dorsey may be suffering from a eating disorder. I will not do it because it would be extremely inappropriate. The only people who should diagnose health problems are, in my opinion, doctors.
However, I recognize that many may be tempted to try to recreate Dorsey's austere diet. In CNBC's post, he reportedly said it improved his concentration and sleep. This could be very beneficial for founders and engineers looking for a benefit. With that in mind, I asked one of the leading dieticians in the UK for their expert opinion on the potential risks and benefits of limiting themselves to a single low carb meal a day.
The strange benefits of starving yourself
Rick Miller is the principal dietitian at London's King Edward VII Hospital, the privileged medical facility of the British Royal Family. It is considered one of the best hospitals in the UK.
Speak to TNWMiller explained that fasting – intermittent and prolonged – is not new. Religious devotees have been using it for millennia as a sign of their faith. Think of Muslims observing the month of Ramadan or Catholics observing the "black fast" during the loan period. It is only recently that fasting has become popular for health reasons.
"To keep the weight to a minimum, intermittent fasting or prolonged fasting is another way to reduce calorie intake, which is the only way to lose body fat," Miller said.
The definition of intermittent fasting is broad and ranges from meal jumping for over eight hours to greatly reduced meal consumption. Similarly, the term "prolonged fasting" can encompass many things, including avoiding eating for 16 hours or more, doing only one meal a day or skipping meals for several days.
Miller explained that the benefits of fasting are to keep insulin levels very low while simultaneously increasing ketone levels in the blood. Ketones are a byproduct of fat burning.
"The combination of these two phenomena may explain why people say they do not feel as hungry when they are fasting as conventional low calorie diets," Miller said. "Certainly, Jack Dorsey does not seem to be an exception to the rule."
However, you do not have to hurry to get these benefits. A decrease in insulin production and ketosis can occur if you are on a low carbohydrate diet with a moderate level of fat and a high level of protein.
Do not try this at home
Fasting is not without risks, however. Miller has expressed concern that people who skip meals may lack several essential nutrients. "My first concern with intermittent fasting is what people choose to eat when they" pause "and eat," he said.
"If you start skipping meals, the meals you eat must be carefully chosen and supplementation will be necessary. [be] necessary in most cases to prevent nutritional deficiencies. I'm afraid someone is just fasting and their diet is not being evaluated by an expert beforehand. "
For what is worthwhile, Dorsey says taking a multivitamin supplement every day, accompanied by a lot of vitamin C.
Miller also worries about "re-eating syndrome" – a life-threatening condition that occurs when a person begins to eat after a period of fasting.
"The risk of developing this disease usually begins to become real after a few days of fasting. We find it in patients with eating disorders who have not eaten for days or who have become malnourished as a result of another illness. Without carefully controlled reintroduction of food after prolonged fasting, the sudden surge of various hormones can cause major metabolic disruption of the body and, in the worst case, heart attacks, "he said.
Miller explained that he regularly sees more customers fasting for several days without understanding the risks involved. In his opinion, prolonged fasting, such as the Dorsey weekend fasts, should not be practiced without careful medical supervision.
The delivery
Jack Dorsey is extremely influential. It would not surprise me if, after reading CNBC's text, some people decide to try to reproduce their unusual diet. As we learned from Miller, fasting has some potential benefits, from weight loss to loss of appetite. But there are also risks.
Your body may end up lacking essential nutrients. As Miller pointed out, in some cases you could cause yourself serious harm, even fatal. Before trying an emergency diet, you should really consult a qualified health professional.
