Introduction: With the change of life and eating habits, diabetes has become the third major factor
affecting human health after cardiovascular and cerebrovascular diseases and malignant tumors.
In China, there are more than 114 million adults with diabetes, accounting for a quarter
of the world's diabetics.

On October 26, 2022, researchers from Duke University and Harvard University in the United States published a research paper
in JAMA Network Open.
The study found that the low-carbohydrate diet reduced blood sugar amplitude more, lost weight, and significantly lowered
fasting blood sugar levels compared to the normal diet group.
The results suggest that adhering to a low-carbohydrate diet may be an effective dietary approach to
the prevention and treatment of type II diabetes.

Low-carb water diet

 01 

When there are too many carbohydrates in the diet, it will be converted into fat and stored in the body, making people too obese and leading to various diseases such as high blood lipids, diabetes, etc
.
The main sources of carbohydrates in the diet are plant foods such as cereals, potatoes, root vegetables and legumes, as well as table sugars
.
Carbohydrates can only be absorbed by digestion and breakdown into glucose, fructose and galactose, which in turn are converted into glucose
by the liver.

Low-carb water diet, that is, strictly limit carbohydrate intake in the diet and increase protein and fat intake
.
In recent years, low-carb water diets have been particularly sought
after by dieters.

Controlled analysis

 02

In this randomized clinical trial, researchers analyzed data from 150 adults, with an average age of 59, whose blood sugar ranged from prediabetes to diabetes levels and who were not taking medication
.
Participants were randomly assigned to a low-carb diet and a regular diet on
a 1:1 basis.

The goal for the low-carb diet group was to have less than 40 grams of net carbohydrates per day for the first three months and less than 60 grams
of net carbohydrates in months 3-6.

After six months, the low-carb diet group had a greater decline in hemoglobin A1c (a
marker of blood glucose levels) compared to the usual diet group.
The low-carb diet group had lower body weight and lower
fasting blood glucose levels.
