Delicious food, but always called junk food. The reason is simple, junk food is meant only.

Foods that provide only some calories and lack other nutrients.

Or the nutrients are beyond the human body.

The amount of food that is required and eventually becomes a surplus ingredient in the human body.

Groundless, in.

Among the classmates, there is Gundam.

The safety and hygiene of these foods are difficult to guarantee.

There will be fewer and fewer of them.

It's not good to eat too much of anything, pay attention to a amount!

Although convenient and delicious, it is not nutritious! So it's called junk food!

If you're overeating foods like pizza, macaroni, cheese, chips, and ice cream, you may be concerned about how they can affect areas like your thighs or waist. But the problem with junk food isn't just weight gain. The harm of junk food is far more serious than this.

For example, those whose daily diet includes a lot of macaroni and cheese, processed luncheon meats, sausage cookies, mayonnaise, and microwave foods containing unhealthy fats will suffer severe negative changes in their metabolism after just five days.

After consuming junk food, the muscles of the study participants (12 healthy male college students) lost the ability to oxidize glucose after meals, which may lead to insulin resistance.

What happens to your metabolism after five days of junk food consumption?

Even if calorie intake remained the same, when men consumed junk food, their muscles' ability to oxidize glucose was disrupted after just five days. This is a very heavy change because muscles play a vital role in the process of removing glucose from the body after a meal.

Under normal circumstances, muscles may break down glucose or store it for later use. Your muscles make up about 30% of your body weight, and if your muscles don't play the critical role they should, they can be the foundation for diabetes and other health problems. According to Time magazine:

After five days on a high-fat diet, people's normal response to a meal is basically either sluggish or not at all,' said [Matthew] Hulver [Ph.D., chair of the Department of Human Nutrition, Food and Exercise at Virginia Tech].

Before starting a week's high-fat diet, that is, when following a normal diet, these men's oxidative goals increased substantially four hours after eating.

After five consecutive days of a high-fat diet, these reactions disappear completely. Under normal dietary conditions, muscles with biopsies utilize oxidized glucose for energy**. 'After the trial, the phenomenon was almost gone,' he says, "and we were really blown away by the impact of the five-day dietary change."
