For example, people whose daily diet contains a lot of macaroni and cheese, processed lunch meat, sausage biscuits, mayonnaise and microwave food containing unhealthy fat will have serious negative changes in their metabolism in just five days.
After eating junk food, the muscles of the subjects (12 healthy male college students) lost their ability to oxidize glucose after meals, which may lead to insulin tolerance.
What will happen to your metabolism after eating junk food for five days in a row?
Even if the calorie intake remains the same, when men eat junk food, their muscles' ability to oxidize glucose will be destroyed in just five days. This is a very important change, because muscles play a vital role in the process of removing glucose from the body after meals.
Under normal circumstances, muscles may break down glucose or store glucose for later use. Your muscles account for about 30% of your weight. If your muscles can't play their key role in glucose metabolism, it will lay a hidden danger for diabetes and other health problems. According to Time magazine:
"'After eating a high-fat diet for five days in a row, people's normal reaction to a meal is basically to become sluggish or completely unresponsive,' [Matthew] Helfer [Ph.D., director of the Department of Human Nutrition, Food and Sports at Virginia Tech] said.
Before starting a week-long high-fat diet, that is, taking a normal diet, these men's oxidation goals will increase significantly after eating for four hours.
After five days of high-fat diet, these reactions completely disappeared. Under normal dietary conditions, the muscles of biopsy slices use oxidized glucose as energy source. He said that after the experiment, this phenomenon basically disappeared. The impact of dietary changes in just five days really shocked us. "
One meal of junk food is enough to ruin your health.
Super Size Me, directed by Morgan Spurlock, is one of the earliest documentaries that vividly present the consequences of eating fast food. Only four weeks later, Spoor Locke's health began to deteriorate, so that his doctor warned him that if he continued the experiment, his life would be seriously threatened.
But as this special study shows, in fact, you don't need a month to feel the impact of a bad diet on your health. In fact, according to a study published in the Journal of American College of Cardiology, your body will begin to change after eating junk food.
When you eat foods that contain a lot of unhealthy fats and sugars, sugar can cause blood sugar levels to soar, which is called "postprandial hyperglycemia". In the long run, this may increase the risk of heart attack, but it will also have short-term effects, such as:
Inflammation of tissue (such as infection)
vasoconstriction
The formation of free radicals harmful to health
Your blood pressure may be higher than usual.
The rise and fall of insulin hormones may make you hungry soon after a meal.
The good news is that a healthy diet can help your body to return to its normal best state, even if it is just a healthy meal. The author of this study, James O'Keefe from the Central American Heart Institute in Kansas City, Missouri, said in an interview with Time magazine:
"At a very basic level, your health and vitality are closely related to your last meal."
Look at the changes in the stomach after eating a fast food.
Braden Kuo of Massachusetts General Hospital used a pill-sized camera to observe the changes of the stomach and digestive tract after people ate Lamian Noodles, a common instant noodle. The results of the study are very shocking. ...
Even after eating for two hours, the ready-to-eat Lamian Noodles is still in a completely undigested state, while the homemade noodles used for comparison are quite different. There may be many reasons for this result.
First, after eating, the digestive system may feel a sense of tension, forcing it to work for several hours to digest this highly processed food. Ironically, most processed foods are very low in fiber content and should be digested quickly, thus affecting blood sugar levels and insulin release.
In addition, food staying in the digestive tract for such a long time will also have a negative impact on the absorption of nutrients, but for processed Lamian Noodles, there is no rich nutrition that can be absorbed by the human body. On the contrary, it also contains many additives, including toxic preservative-tert-butylhydroquinone (TBHQ).
These additives are likely to stay in the stomach with those seemingly "indigestible" noodles, and none of us know what impact it will have on health if it is exposed for so long. But according to common sense, it will definitely not be a good result.
