Can just watching and not eating also exacerbate diabetes?

  With the rise of the live video industry, a variety of food and “eating and broadcasting” programs continue to emerge.
  Many people are addicted to it with the mentality of “I don’t eat, just watch”, thinking that they can not only avoid the trouble of gaining weight, but also experience the fun of eating a big meal.
  Now, a study recently published in Cell Metabolism suggests that “don’t eat and watch” is not completely safe. Just looking at food can trigger an inflammatory response in the brain, and in obese people, this can have serious consequences…
  It starts with the only hormone in the body that lowers blood sugar, insulin.
  In the past, many scholars believed that only after a full meal and blood sugar rise did insulin begin to be secreted to “maintain stability” for the body. They don’t know much about the mechanism of rapid insulin production stimulated by food.
  In order to reveal more details, researchers at the University of Basel in Switzerland started the experiment.
  They took blood samples from fasted mice immediately after they took their first bite. The mice’s blood sugar had not yet risen, but blood samples showed that their insulin levels had risen. This shows that blood sugar rise is not a necessary prerequisite for insulin secretion.
  The paper introduces that short-term stimulation of the senses such as vision, taste, and smell by food can cause this “advanced” secretion (ie, cephalic phase insulin release), which is beneficial to the overall regulation of postprandial homeostasis. In other words, even if you just look, smell, or even make up your mind about the taste of chewing food, your body may have started to “prepare for a rainy day” and release insulin.
  But what does this have to do with brain inflammation?
  It turned out that the researchers found that an inflammatory factor, interleukin-1β (IL-1β), is the key to delivering the “forecast” message. After the perception of food, IL-1β levels first increase, triggering an inflammatory response in the brain, and then “cephalic insulin release” can be initiated.
  This also means that every time you “quench your thirst”, your brain is hard to avoid “inflammation”. It sounds quite serious, even the person in charge of the study said: “It’s surprising, because this inflammatory factor also affects the development of type 2 diabetes.”
  So, does this “inflammation” also pose a threat to our health? Can we continue to “dine in the cloud” happily?
  In thin (or normal-weight) people, the inflammatory response triggered by this “flickering glimpse” is not a big deal, and even has some positive health effects. Comparative experiments in mice also showed that mice that experienced an inflammatory response secreted significantly more insulin and had better glucose tolerance than mice that were not visually or olfactory prepared before meals. But if you are already overweight, be very careful, don’t always watch food and broadcast, and don’t always get close to smelling it.
  Obese people are already in a state of chronic inflammation, and the release of excessive inflammatory factors inhibits their ability to secrete insulin in advance.
  And, over time, their insulin-regulating functions may be further compromised as inflammation “builds up.” Since then, even after the food has been digested, blood sugar regulation has become a problem, which is not worth the loss.
