**The Truth About Single-Food Diets and Raw Food Diets**

**

Generally, single-food weight loss methods lure obese people with claims like "Just eat XX, and you'll lose weight" or "XX is good for weight loss." Those unaware of the underlying principles may mistakenly believe that "good for weight loss" equals "weight reduction," but there are no foods that can actually reduce weight. If a food could cause weight loss, it must contain abnormally active substances that are not suitable for everyday consumption. Currently, many foods are popular for weight loss, most notably seaweed, whole grains, and various vegetables, but these foods do not actually reduce weight; they only suppress weight gain compared to other foods.

Perhaps no country in the world has a more popular single-food diet than South Korea, and there are many types of single-food diets.

The foods used in single-food diets are not actually for weight loss, making them an absolute failure. While reducing overall calorie intake may temporarily produce weight loss, like traditional dieting, the effects are short-lived. Once normal eating habits resume, the "yo-yo effect" will occur. Many people are unaware of the harmfulness of single-food diets and choose them with the mindset of "let's try it, maybe I can succeed if I stick with it." Even if you manage to stick to it for a few days or weeks and successfully lose weight, you'll likely only be able to maintain that weight loss through a single-food diet in the future. Of course, this is impossible. Even if you eventually regain your original weight, you may be left with more painful memories, your body may become more prone to weight gain, and you'll be weak due to the lack of proper nutrition.

Recently, raw food has become incredibly popular in the weight loss world. When people hear "raw food," they often picture raw food products packaged in disposable bags. However, raw food and raw food products are completely different concepts. Raw food refers to eating grains, vegetables, and fruits raw without cooking. Heating and preparing these foods results in the loss of vitamins, minerals, and other nutrients, hence the emphasis on raw food in weight loss methods. Sounds appealing, right? If only these advantages of raw food could be combined with a proper diet, it would be wonderful. However, in reality, raw food is often completely disconnected from a healthy diet. Of course, busy modern people can't possibly consume a balanced diet of all grains, vegetables, and fruits, hence the emergence of raw food products. But replacing a normal diet with raw food can lead to many problems. Under normal circumstances, raw food can only supplement nutrients lacking in the diet; it can never completely replace rice.

So, what is the raw food diet? It refers to a weight loss method that involves not eating rice and only consuming raw food powder mixed with hot water. This is a very torturous method. One packet of raw food contains about 100-200 kcal. While eating one packet might make you feel full, it won't make you feel comfortable. Replacing three meals a day with raw food is essentially the same as a regular diet. Whether it's one or two meals, the raw food diet is harmful to your health. The best way to lose weight is to improve your eating habits and the content of your diet.

The raw food diet, similar to other weight loss methods, involves forbidding lunch and replacing breakfast and dinner with raw foods. Generally, the extremely low daily calorie intake leads to some weight loss, but this is not because these foods themselves have a weight-loss effect. There are several issues with raw food powders. Most people drink large gulps of prepared raw food powder, but for adults with teeth (front teeth and canines), consuming dairy-like foods goes against natural rhythms. Infants don't have teeth and therefore drink milk, but once teeth erupt, they begin eating weaning foods. Weaning refers to stopping breastfeeding. A one-year-old child has four teeth on each side, and by two years old, they have almost all their teeth, indicating they can chew food. Chewing food promotes brain development and stimulates saliva production, thus improving digestion. This is a natural process. Adults typically only consume dairy-like foods when they are sick, weak, or have reduced digestive capacity. Consuming dairy-like foods under normal circumstances can actually lead to abnormal symptoms.

First, gastrointestinal function declines. The stomach and intestines' job is to churn food. If you only eat foods that don't require churning, their activity decreases. Just as your hands and feet become thinner if you don't use them, the muscles of your stomach and intestines will also shrink and gradually lose their churning ability. When you return to a normal diet and lifestyle, your stomach and intestines cannot perform their normal functions, thus leading to digestive problems.

Secondly, not chewing food can impair brain responsiveness. Elderly people who have lost all their teeth are more prone to dementia. Chewing food stimulates brain function and promotes blood circulation to the brain. What are the consequences of replacing solid foods with dairy products?

Third, one cannot appreciate the natural flavor of food. Every food has an inherent flavor, and this flavor plays a positive role in the body. In Traditional Chinese Medicine, the inherent flavors of food are categorized into five types: sour, sweet, bitter, pungent, and spicy. Bitterness has the functions of clearing heat, relieving stagnation of qi, promoting bowel movements, drying dampness, and purging fire while preserving yin. Pungentness has the functions of dispersing, promoting qi and blood circulation. If dairy products are consumed, the tongue cannot perceive these flavors, thus hindering the food from fulfilling its normal function.

Whether it's raw food or diet supplements, completely replacing normal food is equivalent to starving yourself. Please review the side effects of the starvation methods we discussed earlier.
