巨大的不确定性? 哈哈，基本就是多吃肉不吃糖。减少碳水。
巨大？
依我看有巨大的
确定性，
绝对有助于减少糖和碳水。这是绝对的科学，
考虑到西方被糖尿病折磨的害死的大量人口，简直就活菩萨。
确定性足够高了。而且绝对高。
具体怎么搞，问医生。但是，不能封闭不让民众接触。

我粗略研究过一阵Keto，放弃了。
感觉这理论主要是迎合西方牛排菜谱的饮食习惯，中国人和东方人，绝大多数以各种淀粉为主食，总体健康水平不比洋人差，香港，日本都是世界上数一数二的长寿国家。中国百岁老人也很多。
不反对大家各自相信各种理论，不推销。

二型糖尿病是華裔人口中最普遍的糖尿病，通常是因胰島素抗拒引致。肥胖和過重是導致二型糖尿病的主因。但很多華裔即使沒有肥胖問題，也可能罹患糖尿病。遺傳基因以及環境的因素，使得華人產生胰島素抵抗和第二型糖尿病機率超過白人。很多研究發現，在同樣的身高和體重情況下，華人患二型糖尿病的機率比白人高出60%1。
- 同等腰圍下，華人的脂肪組織高過白人。腰圍愈大，腹部肥肉愈多，得糖尿病的風險就愈高。
- 華人通常肌肉較少，因為肌肉可以利用血糖，肌肉少通常血糖較高。
- 華人的食物血糖指數偏高，特別是米飯麵食。

Stanford Medicine News Keto and Mediterranean good for diabetes
In a trial of the two low-carb diets, both were similarly effective in controlling blood glucose. Keto’s more severe carb restrictions did not provide additional overall health benefits.
July 8, 2022 - By Nina Bai
Stanford researchers found that the Mediterranean diet, rich in whole grains, fish and vegetables, was as effective as the carbohydrate-restrictive ketogenic diet in controlling blood glucose in a study of people who tried both. Participants also found the Mediterranean diet easier to follow.

A low-carbohydrate diet is generally recommended for people who have Type 2 diabetes or who are at risk of developing the disease. But there isn’t wide agreement on how low to go in carbohydrate consumption or which carbohydrate foods to include, and little research is available to help people make informed decisions.
A new trial by investigators at Stanford Medicine has compared two popular low-carb diets — ketogenic and Mediterranean — in their effect on blood glucose, cardiometabolic risk factors, weight loss and nutrition, as well as how easily people can adhere to them.
The ketogenic diet is an ultra-low-carb, very high-fat diet that involves a drastic reduction in carbohydrate intake. The Mediterranean diet is a low-carb, moderately high-fat diet that emphasizes vegetables, legumes, fruits, whole grains, olive oil and fish.
Both diets received high marks in controlling blood glucose levels and aiding weight loss, but the ketogenic diet was lower in several nutrients, particularly fiber, and was more difficult for study participants to follow in the long run, according to findings published May 31 in the American Journal of Clinical Nutrition.
Americans get roughly half their daily calories from carbohydrates, with about 80% of those carb calories coming from added sugars and refined grains — think soda, candies, bagels, pastries and pizza crust.
To manage or prevent diabetes, the American Diabetes Association recommends the Mediterranean diet and other low-carb diets, as long as they minimize added sugars and refined grains and include non-starchy vegetables.
The ultra-low-carb ketogenic diet fulfills these criteria. But its dramatic rise in popularity in recent years has nutritionists like Gardner concerned.
Christopher Gardner
“The lower in carbs you go, the more you’re wiping out entire food groups that are considered very nutrient dense and healthy,” he said, noting that to achieve an extreme restriction of carbohydrates, the ketogenic diet prohibits legumes, fruits and whole grains. “What is it about this diet that would be so compelling that you would give up some of those central tenets of health and nutrition?”
In the ketogenic diet phase, participants followed a version known as the well-formulated ketogenic diet. They were advised to limit carbs to 20-50 grams/day (about 80% less than usual) and proteins to 1.5 grams per kilogram of their ideal body weight per day, and to consume as much as they wanted in fats. They were asked to consume at least three servings of non-starchy vegetables a day.
In the Mediterranean diet phase, participants were advised to follow a mostly plant-based diet that included vegetables, legumes, fruits, whole grains, nuts and seeds, as well as fish for animal protein and olive oil for fat.
Both diets encouraged eating lots of vegetables and eliminating added sugars and refined grains as much as possible. The main question, Gardner said, was whether the keto diet offered additional health benefits from eliminating legumes, fruits and whole grains.
To set the participants up for success, the study sent ready-to-eat food to both groups during the first four weeks of each diet through the food delivery service Methodology. Short of feeding people all their meals in a lab, this approach was the best way to maximize adherence to the diets, Gardner said.
For the remaining eight weeks, participants were responsible for choosing and preparing their own food, giving researchers insight into how people realistically follow the diets. The participants were encouraged to be honest in reporting how well they were following the diets. “Don’t feel that you have to impress us,” they were told.
The researchers found that both diets improved blood glucose control, as indicated by similar drops in HbA1c levels (9% on keto and 7% on Mediterranean). Weight loss was also similar (8% on keto and 7% on Mediterranean), as were improvements in fasting insulin and glucose, HDL cholesterol, and the liver enzyme ALT.
Each diet had one other statistically significant benefit: LDL cholesterol increased on the keto diet and decreased on the Mediterranean diet — a point for Mediterranean. Triglyceride decreased on both diets, but it dropped more on the keto diet — a point for keto.
In nutrient levels, the ketogenic diet provided less fiber; thiamin; vitamins B6, C, D and E; and phosphorus. Only vitamin B12 was higher on the ketogenic diet.
“The one thing everybody did pretty well was limiting added sugar and refined grains. That was the main message for both diets,” Gardner said.
“The keto diet was more polarizing,” he said. “What we were hearing is that some people just couldn’t do the keto because it was too restrictive.” Yet a few may have found it simpler, at least initially, to focus just on avoiding carbs, according to Gardner.
The takeaway, Gardner said, is that there was no additional overall health benefit to cutting out legumes, fruits and whole grains to achieve an ultra-low-carb diet. For people with diabetes or prediabetes, the less restrictive Mediterranean diet was similarly effective in controlling glucose and likely more sustainable.
“Restricting added sugars and refined grains and emphasizing the inclusion of vegetables should be the focus,” Gardner said. “There’s no reason to restrict heart-healthy, quality carbohydrate foods above and beyond.”

The research was supported by funding from John and Meredith Pasquesi; Sue and Bob O’Donnell; the Teton Fund; the National Heart, Lung, and Blood Institute (National Institutes of Health grant T32HL007034); a Stanford Clinical Translational Science Award (NIH grants UL1TR001085 and TL1R001085); and Stanford Diabetes Research Center (NIH grant P30DK116074).
Keto and Mediterranean diets both help manage diabetes, but one is easier to maintain

Low-carb diets for diabetes
“The main issue in diabetes is the inability to manage your blood glucose, and the biggest effect on your blood glucose is your diet,” said Christopher Gardner, PhD, the Rehnborg Farquhar Professor, a professor of medicine and the director of nutrition at the Stanford Prevention Research Center, who is the lead author of the study.Americans get roughly half their daily calories from carbohydrates, with about 80% of those carb calories coming from added sugars and refined grains — think soda, candies, bagels, pastries and pizza crust.

Eating for science
In the new study, conducted from June 2019 to December 2020, Gardner and his team recruited 40 adults with Type 2 diabetes or prediabetes to try both the ketogenic diet and the Mediterranean diet. Half the participants started with the ketogenic diet, and the other half with the Mediterranean diet. After 12 weeks, the groups switched and tried the other diet for 12 weeks. This crossover design allowed participants to act as their own controls.In the ketogenic diet phase, participants followed a version known as the well-formulated ketogenic diet. They were advised to limit carbs to 20-50 grams/day (about 80% less than usual) and proteins to 1.5 grams per kilogram of their ideal body weight per day, and to consume as much as they wanted in fats. They were asked to consume at least three servings of non-starchy vegetables a day.
In the Mediterranean diet phase, participants were advised to follow a mostly plant-based diet that included vegetables, legumes, fruits, whole grains, nuts and seeds, as well as fish for animal protein and olive oil for fat.
Both diets encouraged eating lots of vegetables and eliminating added sugars and refined grains as much as possible. The main question, Gardner said, was whether the keto diet offered additional health benefits from eliminating legumes, fruits and whole grains.

For the remaining eight weeks, participants were responsible for choosing and preparing their own food, giving researchers insight into how people realistically follow the diets. The participants were encouraged to be honest in reporting how well they were following the diets. “Don’t feel that you have to impress us,” they were told.
Similar clinical benefits
At various points, researchers collected blood samples to evaluate blood glucose control, lipid control, body weight and other clinical measures. Throughout the study, participants also were interviewed on their adherence to and satisfaction with the diets. Thirty-three participants completed the study, with several dropping out due to COVID-19 disruptions.The researchers found that both diets improved blood glucose control, as indicated by similar drops in HbA1c levels (9% on keto and 7% on Mediterranean). Weight loss was also similar (8% on keto and 7% on Mediterranean), as were improvements in fasting insulin and glucose, HDL cholesterol, and the liver enzyme ALT.
Each diet had one other statistically significant benefit: LDL cholesterol increased on the keto diet and decreased on the Mediterranean diet — a point for Mediterranean. Triglyceride decreased on both diets, but it dropped more on the keto diet — a point for keto.
In nutrient levels, the ketogenic diet provided less fiber; thiamin; vitamins B6, C, D and E; and phosphorus. Only vitamin B12 was higher on the ketogenic diet.
Diets in the real world
As expected, when food was delivered, participants stuck to both diets relatively well, scoring an average of 7.5 on a 10-point adherence scale. When participants had to provide their own food, adherence on both diets dropped about two points on average.“The one thing everybody did pretty well was limiting added sugar and refined grains. That was the main message for both diets,” Gardner said.
“The keto diet was more polarizing,” he said. “What we were hearing is that some people just couldn’t do the keto because it was too restrictive.” Yet a few may have found it simpler, at least initially, to focus just on avoiding carbs, according to Gardner.
When the research team checked in with the participants three months after the trial, on average, they had maintained lower blood glucose levels and weight loss. Notably, they were eating closer to a Mediterranean diet than to a keto diet. Even the participants who had followed the keto diet nearly perfectly during the trial largely gave it up afterward.
The takeaway, Gardner said, is that there was no additional overall health benefit to cutting out legumes, fruits and whole grains to achieve an ultra-low-carb diet. For people with diabetes or prediabetes, the less restrictive Mediterranean diet was similarly effective in controlling glucose and likely more sustainable.

通常建议患有 2 型糖尿病或有患该疾病风险的人采用低碳水化合物饮食。但对于碳水化合物的摄入量要低到什么程度或应包括哪些碳水化合物食物，人们并没有达成广泛的共识，而且很少有研究可以帮助人们做出明智的决定。
斯坦福大学医学院的研究人员进行的一项新试验 比较了两种流行的低碳水化合物饮食——生酮饮食和地中海饮食——对血糖、心脏代谢危险因素、减肥和营养的影响，以及人们坚持这些饮食的难易程度。
生酮饮食是一种超低碳水化合物、极高脂肪的饮食，涉及大幅减少碳水化合物的摄入量。地中海饮食是一种低碳水化合物、适度高脂肪的饮食，强调蔬菜、豆类、水果、全谷物、橄榄油和鱼。
根据5 月 31 日发表在《科学》杂志上的 研究结果，这两种饮食在控制血糖水平和帮助减肥方面都获得了很高的分数，但生酮饮食的多种营养素含量较低，尤其是纤维，而且从长远来看，研究参与者更难以遵循。美国临床营养杂志。

这位YouTuber是不是没提过生酮饮食可能带来的不良反应？
他是不是没提过有些人群不适合生酮饮食？
他的影响力已经很大，YouTube大概觉得需要让他传递的信息更负责任，网络上判断能力不足的人很多，YouTube大概想多负些社会责任。

禁他的原因是？
就算我不聽他的，但也不懂為何有需要禁他的必要性。畢竟意見自由，想生酮就生酮，想賣產品就賣，沒理由禁他。話說回來，大藥廠說的謊絕對比他多上萬倍！YT又有禁止支持大藥廠謊言的「專家」嗎？
聽過諾貝爾獎委員會回應中國記者詢問mRNA疫苗的長期安全性嗎？說禁止，該先禁的就是這些連回答時都表情心虛、語氣怯懦的專家教授！
