What conditions must weight-loss foods meet to ensure they do not negatively impact health?

The main nutrients in food include protein, carbohydrates, fat, vitamins, minerals, fiber, and water, of which the first three provide energy.

In the Chinese diet, carbohydrates make up the largest proportion, followed by fats, and protein the least.

From a nutritional perspective, however, it should be high in protein, moderate in carbohydrates, and low in fat.

Carbohydrates, also known as sugars, are mainly provided by grain products, while vegetables contain very little carbohydrates.

Fat is mainly provided by meat and food, while protein content is relatively high in eggs, meat and beans. After these three substances enter the human body, they are digested, absorbed and utilized. Each gram of protein or carbohydrate produces 16.7 kilojoules of energy, while each gram of fat produces 37.7 kilojoules of energy.

Obesity is more common among people with good living conditions and irregular eating habits. It can also be described as a disease of nutritional imbalance, mainly caused by overnutrition.

For obese patients, since their intake exceeds their output, they must ensure that their output exceeds their intake in order to lose weight. A low-calorie diet is the principle.

Therefore, apart from consistently and effectively reducing calorie intake and increasing energy expenditure, there are no other effective methods or medicines for weight loss.

What are the principles of weight-loss foods?

① Dietary energy intake should be controlled gradually and appropriately. This means that weight loss should mainly reduce calorie intake, rather than eliminating all nutrients.

The energy provided by the diet must be lower than the actual energy consumed by the body. Of course, the energy and nutrition in the diet should be reasonably arranged according to the stages of human growth, development, maturity and aging. Generally, it should not be less than 1000-1600 kcal, because these calories are the calories required to maintain the body's basic life activities such as heartbeat, blood pressure, respiration, and body temperature.

② A low-salt, light diet can reduce sodium and water retention, which is common in obese individuals, and can reduce food intake.

Obese people often suffer from coronary heart disease and high blood pressure, so it is best to reduce salt intake.

③ It is best to eat a balanced diet, but the quantity should be slightly less.

In limiting energy-consuming foods, sucrose, fructose, coffee, exercise fats, and alcohol should be strictly restricted. For those with moderate to severe obesity, carbohydrates can be restricted.

④ Ensure the body receives essential nutrients, such as protein (animal and plant), which is an important component of body tissues and cells; iron, which is the raw material for hematopoiesis; calcium, which is the main component of bones; and vitamins, which regulate metabolism and physiological functions in the body.

⑤ A diet rich in fiber promotes normal gastrointestinal motility, reduces calorie absorption, prevents hunger, and helps eliminate toxins from the body as soon as possible.

⑥ It should be designed to suit the tastes, eating habits, and financial capabilities of dieters, satisfy their personal preferences and diverse lifestyle needs, and avoid excessive restrictions in order to be widely accepted by dieters.

Losing weight requires patience and determination.

Do not rush into it. You must develop good eating habits and stick to them in the long term. Correct and scientific weight loss will only benefit your health.

What foods are good for weight loss?

Foods that are beneficial for weight loss are those that are low in calories and can naturally control weight and maintain a slim figure after consumption.

(1) Legumes

All beans, regardless of type or color, are nutritious.

Beans are vegetables, but they are as rich in protein as meat.

Every 30 grams of dried beans provides 6 grams of protein (1/10 of the daily requirement).

This means that if you eat beans, you don't need to eat more meat.

For example, red beans are sweet and sour in taste, and neutral in nature. They are a high-protein, low-fat food with the functions of clearing heat, promoting diuresis, activating blood circulation, and reducing swelling.

The simplest way to increase dietary fiber is to eat a bowl of oatmeal and three bran muffins every day.

Consistent consumption over a period of time can lead to weight loss.

(10) Vinegar

In recent years, a trend of using vinegar for weight loss has emerged in countries such as the United States and Japan.

Experts believe that the amino acids contained in vinegar can not only consume body fat, but also facilitate the metabolism of sugars and proteins, resulting in a good weight loss effect.

The method is as follows: Take 20 grams of vinegar, divided into two doses, one at noon and one at night.

Generally, you can lose 3-5 kilograms within one month.

Should you restrict your water intake when trying to lose weight?

During weight loss, it is necessary to control your diet appropriately, but some people even control their water intake, believing that drinking too much water will make them fat, which is incorrect.

Since water and food are the main substances that humans rely on to sustain life, they are also the main material basis for people to adjust their body shape. Some people who are eager to lose their excess weight often adopt two methods: restricting water intake and dieting in order to achieve their goal. As a result, a series of adverse consequences are caused. Here we analyze the harm that this one-sided view can bring to people, and hope that dieters will pay attention.

Water is an important component of the human body and plays a vital physiological role.

Water is essential for various bodily functions such as metabolism, temperature regulation, digestion and absorption, blood circulation, and excretion.

If the body loses 5% of its body weight in water, physiological functions will be impaired, resulting in increased heart rate, decreased stroke volume, reduced circulating blood volume, reduced blood flow to various organs, impaired organ function, increased body temperature, and muscle weakness.

An experiment was conducted showing that when water intake was restricted to 900 ml per day, weight loss was rapid, but of the weight lost, fat accounted for only 13% and water accounted for 84%. When water intake was not restricted, although weight loss was slower, more fat was lost, at 25% and water accounted for 75%.

Our goal in losing weight is primarily to reduce excess fat, not water, therefore the latter is more effective.

Fat metabolism requires more water than carbohydrate metabolism, and insufficient water in the body can affect fat metabolism.

Drinking more water will not increase the weight of body fat.

Obesity is caused by excess body fat, not excess water, as fat contains very little water.

Therefore, drinking water is not related to fat or obesity.

For normal people, the amount of water they take in and the amount of water they excrete each day are roughly equal, so drinking water will not increase weight. In fact, drinking more water can help excrete harmful substances.

However, drinking too much water can burden the gastrointestinal tract, heart, and kidneys, which is harmful to health. Therefore, it is important to drink water in moderation.

Some people believe that drinking eight glasses of water a day is the most suitable.

Everyone has a desire for beauty; which girl doesn't want a slim figure, and which man doesn't want a strong physique?

However, weight loss should never be achieved solely by reducing food intake.

Some people, especially some young people, are eager to achieve a beautiful figure, but they do not pay attention to science and blindly lose weight. As a result, they become thinner but their health deteriorates.

According to foreign research reports, one-third of patients who use starvation therapy to lose weight will develop gallstones within four months. This is because drastic dietary restriction leads to a high degree of cholesterol saturation in bile, which easily forms cholesterol stones.

Using simple food reduction therapy can lead to malnutrition, general weakness, dizziness, drowsiness, and in more serious cases, if the diet is reduced to almost a state of fasting, harmful substances will accumulate in the body, metabolic disorders will occur, and even life may be endangered.

Wenhui Daily once reported on a young woman who was 1.65 meters tall. In order to lose weight, she only ate 50 grams per meal, and her weight dropped from 50 kilograms to 35 kilograms. In the end, she suffered from "anorexia nervosa" and died because she could not eat or drink anything.

Therefore, for obese patients, weight loss should not rely solely on diet reduction or starvation. Instead, a scientific diet therapy should be implemented, reducing the intake of sweets, high-calorie foods high in fat and oil, and increasing the intake of fresh vegetables, fruits, and nutrient-rich low-calorie foods. In addition, moderate physical activity is necessary. Based on one's age, height, and weight, one should gradually reduce excess body fat to achieve both a beautiful figure and good health.
