From 1975 to 2014, the Chinese male obese population increased from 700,000 to 43.2 million, and the female obese population increased from 1.7 million to 46.4 million. second.
Obesity not only affects aesthetics, but also a healthy fatal killer. For obese people, weight loss is imminent! For weight loss, diet is essential.
What type of diet should obese people choose?
There are 4 diet structures that are more popular at the moment:
Low fat diet: intake of high fat can cause obesity, diabetes, heart disease, and even cancer;
Low carbon water and high fat diet: carbohydrate 35%, protein 20%; improve sugar metabolism.
Ketogenic diet: a high-fat, low protein, extremely low carbohydrate, and other nutrients with suitable formula (carbohydrate 70-75%, protein 20-30%).
Diet with a wide range of carbohydrates: What is the type of fat type or what kind of carbohydrates in what kind of fat, and the ratio of dietary fat and carbohydrates has almost no health significance.
Want to lose weight, which diet models are good? Today we will talk about the more popular ketogenic diet. In addition, the ketogenic diet is also written into the guidelines and consensus, which is used in: clinical pathotherapy for simple ketogenic treatment, intervention of type 2 diabetes Chinese expert consensus (2019 edition), intervention of multi -cyst ovarian syndrome Chinese expert consensus (2018 New Year).
In other words, the ketogenic diet can not only treat obesity, but also interfere with diabetes. Is the ketogenic diet so amazing? Where is the basis? Will it be harmful to the body?
On the 19th, at the high blood pressure annual meeting held in Xiamen, Professor Chen Luyuan, chief physician of the Department of Cardiology of the People’s Hospital of Guangdong Province, reported to us the “Advantages and Risks of Melars for Losing Loss” for us. You can take a look together.
Why can the ketogenic diet lose weight?
What is the effect of weight loss?
饮 What is ketogenic diet?
Simply put, eat less staple food and even do not eat staple food. The energy of our bodies does not come from sugar, but ketone bodies (acetyl-acetyl, β-hydroxyl acid, acetone), which is converted from the liver during fat decomposition. Become “ketogenic”.
Therefore, it is necessary to restrict the intake of carbohydrates so that the body is switched from the mode of burning carbohydrates to burning fat. Properly limit protein can help the body enter the state of ketogenic ketogenic and avoid aggravating the burden on the kidneys. (Carbon 70-75%, protein 20-30%)
Under the action of a ketogenic diet, the content of blood ketone body can be increased to the ketone body value equivalent to a healthy person who is hungry, becoming the main source of energy of the human body.
What is the effect of ketogenic diet to lose weight?
A survey report published between 2003-2011 in SCI magazine showed an average of 4.8-12.8 kg of weight loss in half a year. %, Fat calories account for 50%to 57%.
At the annual meeting of the 2017 American Obesity Association, Professor GOSS of the University of Alabama reported:
A 8 -week random control clinical study showed the average weight loss of the ketogenic diet group to 9.7%, while the low -fat diet group only reduced 2.1%;
In terms of abdominal fat, the ketogenic diet group is nearly 3 times more than a low -fat diet group. The study also found that even if the fat or total heat is not strictly limited, the ketogenic diet solution can still make the subjects lose weight by 10 pounds quickly within 2 weeks.
能 Why can ketogenic diets lose weight?
There are 5 reasons for the effective weight loss of ketogenic diet:
Enhanced fullness (fat and protein);
Inhibit appetite (ketone body has the effect of inhibiting appetite);
Inhibit fat synthesis and promote fat decomposition (reducing insulin levels, and insulin is a hormone that promotes fat synthesis);
Increase energy consumption (fat or protein forms glucose through glycogen, bringing energy consumption);
The ketogenic diet with resistance exercise can help enhance muscle.
Professor Chen Luyuan also cited an example to explain that he saw a company manager. The whole person looked thinner than before, but the weight did not decrease, because this manager has been in fitness for a long time, increasing the percentage of muscles, reducing fat percentage percentage content.
Why can the ketogenic diet still interfere with diabetes?
The theoretical basis for ketogenic diet to treat diabetes?
The theory of ketogenic diet theory of type 2 diabetes is based on strict restrictions on the intake of carbohydrates to reduce intestinal sugar absorption, reduce blood sugar levels and blood sugar fluctuations;
Reduce insulin fluctuations and reduce peak values;
Activating AMPK pathways to reduce insulin resistance is similar to the principle of bipolar muscle.
AMPK is a protein that is responsible for the phosphorylated glucocyclated protein bolt (GSV), which is equivalent to a door that controls glucose transportation. The low -carbon diet improves the work efficiency of AMPK.
In May 2018, Professor Emmanesbury at the University of Sydney studied changes after restricting carbohydrates by restricting carbohydrate patients in 2412 diabetic patients. The result found that the proportion of carbohydrates accounted for <26%, and glycated hemoglobin decreased significantly.
The heat of carbohydrates accounted for 26% -45%, and there was no significant change.
The proportion of carbohydrates is> 45%, no significant changes.
From 2002 to 2018, 23 clinical trials summarized: The low -fat diet that we usually advocate did not reduce the effect of glycated hemoglobin.
The American Diabetes Association clearly stated that a low -carbon water diet can improve blood sugar and may reduce the amount of medication for patients with type 2 diabetes.
How about the safety of ketogenic diet? Can I eat it casually?
The effect of ketogenic diet is clear for the treatment of diabetes, but the clinical trials of ketogenic diet therapy for diabetes and obese patients are rarely more than 2 years, so the long -term effectiveness and safety of the ketogenic diet for these patients is unknown.
For patients with diabetes, Professor Chen Luyuan does not recommend trying to blindly try a ketogenic diet without authorization. It is necessary to scientifically carry out scientifically under the guidance of clinical nutritionists and endocrine doctors to monitor the possible risks in time to deal with it in time.
In addition, Professor Chen Luyuan also added: “Such an extreme diet model is also difficult to persist for a long time.”
低 Low carbon water VS low -fat diet long -term comparison
For a long time, we have always advocated low -fat diet, which is better for diabetes and obesity, low -carbon water diet and this diet?
In the short term, if insulin resisting the crowd (diabetes or obesity) uses a low -carbon water diet, you can obtain more health benefits; the difference between the two is not obvious when it focuses on long -term effects;
<!-2586: Diabetic terminal page
In a 12 -month study: When the calories are equal, the level of carbohydrate and low -fat diet is exactly the same for blood sugar, blood lipids and weight loss in an empty stomach;
Low carbon water diet can burn more fat, and low -fat diet can burn more carbohydrates. Therefore, as long as the calorie is the same as the protein, the weight loss effect of the two ways of diet is the same.
