    JAMA Sub-Journal: Sugar-free beverages increase the appetite of women and obese people, and are not conducive to weight loss
    .

    With the development of the economy and the improvement of living standards, obesity has become a major public health problem worldwide
    .
    According to statistics from the World Health Organization (WHO), nearly 2 billion people in the world are overweight or obese

    .
    From 1975 to 2016, the global obesity rate almost tripled

    .
    Every year, overweight or obesity causes 2.
    8 million deaths

    .

    In fact, obesity is not only a feature, but also a disease
    .
    Obese people not only have inconvenience in life and decreased exercise capacity, but also are susceptible to metabolic diseases and cardiovascular and cerebrovascular diseases

    .
    In addition, many studies have shown that obesity is related to more than a dozen cancers

    .
    The increase in disease risk is related to the decrease in prognosis and survival rate

    .

    In order to reduce the impact of sugar on health and obesity, more and more people start to consume artificial sweeteners instead of ordinary sugar (sugar substitute)
    .
    These artificial sweeteners have the sweetness of sugar but do not produce calories

    .
    People think it can be used as a healthy way of eating, so it has been widely sought after in recent years

    .

    However, the health effects of artificial sweeteners are still controversial, and their effects on appetite, glucose metabolism and body weight have not yet formed a clear consensus
    .

    On September 28, 2021, researchers from the University of Southern California published a randomized crossover trial titled "Obesity and Gender and the Effects of Sucralose and Sucralose on Differences in Appetite and Reward Management" in the Journal of the American Medical Association.
    "Thesis

    .

    The results of this study on the effects of artificial sweeteners on human brain activity and appetite show that beverages containing artificial sweetener sucralose may increase the appetite of women and obese people
    .

    The corresponding author of the study and an associate professor at the University of Southern California, Kathleen Page, said that many people now use artificial sweeteners to help lose weight, but this is controversial
    .

    Some studies have shown that artificial sweeteners can help weight loss, but there are also studies that show that artificial sweeteners may cause weight gain, promote type 2 diabetes and other metabolic disorders
    .

    In order to find out the reasons behind these contradictory research results, the research team conducted a new experiment
    .
    The research team recruited 74 participants and divided them into three groups

    .
    They each drank 300 ml of sucrose beverage and sucralose beverage and water

    .

    Note: Sucralose is a widely used artificial sweetener with the characteristics of no energy, high sweetness and pure sweetness
    .

    These participants include men and women, including healthy weight, overweight and obesity, the purpose is to study the impact of artificial sweeteners on different populations
    .

     

     

    Within two hours after drinking, the research team performed three tests or records:

    1.
    After seeing pictures of high-calorie foods such as hamburgers and donuts, use a technique called functional magnetic resonance imaging (fMRI) to check the activation of the area of ​​the brain responsible for appetite;

    2.
    Blood sugar level, insulin level and other metabolic hormone levels;

    3.
    The amount of food that the participant last consumed in the buffet

    .

     

    Functional Magnetic Resonance Imaging (fMRI) studies have shown that compared with drinks containing real sugar, women and obese people have increased activity in the brain regions responsible for appetite after drinking beverages containing sucralose
    .
     

    The study also showed that, compared with beverages containing real sugar, the hormones related to satiety were reduced after participants drank sucralose-containing beverages, indicating that beverages containing artificial sweeteners may not be effective in suppressing satiety Sense
    .

    In addition, after the female participants drank sucralose-containing beverages, they ate more at the buffet, while the food intake of the male participants did not change
    .

     

     

    The research team said that through the study of different populations, these results show that artificial sweeteners have an impact on human nerves and behavior
    .
    Women and obese people may be more sensitive to artificial sweeteners

    .
    They drink artificial sweeteners

    .
    Drinks may cause hunger in the brain, leading to more calorie intake, which is obviously not conducive to weight loss

    .

    This study also reminds us that popular sugar-free beverages that use artificial sweeteners may not be a good choice for weight loss
    .
    They can even increase appetite and cause weight gain

    .
