過午不食，即13點之後一直到第二天早晨都不攝入任何食物，據說用這種方法減肥成功的人不在少數，成為了當下時興的減肥方法之一。而事實上，這種做法並不科學，我們的身體需要規律的飲食來維持正常機能，過午不食打破了這種規律，會引發一系列健康問題。

The dangers of skipping lunch and eating

Unbalanced nutrient intake

• The human body needs enough energy to function properly, and these energy sources are mainly carbohydrates, fats, and proteins. If you skip food after noon and don't have energy in the afternoon and evening, it may lead to a lack of total energy intake. Long-term insufficient energy intake can make people feel tired and fatigued, affecting daily work and life.
• The human body needs a variety of vitamins and minerals to maintain normal physiological functions. Skipping food late in the afternoon can lead to inadequate intake of these foods, triggering vitamin and mineral deficiencies. For example, vitamin C deficiency may affect collagen synthesis, leading to problems such as rough skin and bleeding gums. Calcium deficiency can damage bone health and increase the risk of osteoporosis.

Metabolic and endocrine disorders

• Skipping lunch for long periods of time can make the body think that it is in a "starvation state", and in order to conserve energy, the body will lower its basal metabolic rate. When the basal metabolic rate is reduced, the body uses energy more slowly, which is not only detrimental to weight loss, but also makes it easier for the body to accumulate fat after returning to a normal diet.
• Skipping lunch for a long time can lead to endocrine disorders, such as diabetes, abnormal thyroid hormone secretion or menstrual disorders.

Digestive problems

• Skipping food at noon will leave the stomach acid without food to neutralize it in the afternoon and evening, and stomach acid may irritate the gastric mucosa, causing symptoms such as stomach pain and acid reflux. Long-term abnormal gastric acid secretion may also lead to gastritis, stomach ulcers and other diseases.
• Skipping food after lunch will disrupt the gastrointestinal peristalsis rhythm, prolong the stay time of food in the gastrointestinal tract, and easily cause constipation, bloating and other problems. In addition, slowing down gastrointestinal motility may also affect the balance of intestinal flora and increase the risk of intestinal diseases.

Normal eating spacing and gastrointestinal health

As an important part of the human digestive system, the normal functioning of the stomach and intestines depends on regular meal intervals. Normally, eating smaller, more frequent meals is ideal.

例如，早上7點左右吃早餐，到10 - 11點左右可適當加餐，像吃個水果或者一小把堅果。午餐在12 - 13點左右，下午3 - 4點又能加餐，如喝杯優酪乳或者吃幾片全麥餅乾，晚餐則在18 - 19點左右。

This interval allows the stomach and intestines enough time to digest food and avoid prolonged fasting. If you don't eat for a long time, you will have gastrointestinal problems. When the stomach and intestines are empty for a long time, gastric acid is continuously secreted and there is no food neutralization, which will corrode the gastric mucosa, which is easy to cause stomach pain, stomach distension and other uncomfortable symptoms. In addition, long-term irregular meal intervals may also lead to intestinal dysbiosis, affecting the normal function of the intestines, and then causing problems such as constipation or diarrhea.

How to choose food that ensures a reasonable supply of energy throughout the day

Food choices are crucial to ensuring a reasonable supply of energy throughout the day.

• In terms of staple food, the combination of thickness and thickness is a good choice. Oats are high-quality whole grains, rich in dietary fiber and β-glucan, which provides long-lasting energy. For breakfast, cook a bowl of oatmeal porridge and cook it for 20 - 0 minutes in a 0:0 ratio of oats and water.
• Protein sources are indispensable. Eggs are a good source of protein, rich in high-quality protein, vitamins and minerals, and you can eat 2-0 eggs a day, and boiled eggs are the healthiest way to eat.
• Fatty foods should also be consumed in moderation. Olive oil is a healthy oil rich in monounsaturated fatty acids and can be used in place of other oils and fats, such as stir-fried vegetables or cold vegetables, when cooking.
• Also, plenty of fruits and vegetables. Apples are rich in pectin and vitamins that provide energy and nutrients, so it's a good idea to eat 2-0 apples a day.

In short, although skipping lunch may have a weight loss effect in the short term, it is harmful in the long run. We should choose a healthy lifestyle, including reasonable meal spacing, correct food choices, good lifestyle habits, etc., so that we can truly maintain health and health.
