Why is weight loss more difficult for women? Beware of the impact of anemia on metabolism and follow these iron supplementation guidelines.

Anemic women find it difficult to lose weight.

Due to their unique physiological characteristics, women lose a certain amount of blood every month. Furthermore, women are the main force in the weight-loss movement, often cutting out meat from their diets. Therefore, many women are at high risk of anemia. The most common symptoms of anemia are those many women experience: fatigue, pale complexion, cold hands and feet, and extreme sensitivity to cold. It's important to know that for every 1°C decrease in body temperature, the body's metabolism decreases by 13% to 14%.

Iron-deficiency anemia is the most common type of anemia, as iron is a crucial component of hemoglobin. The results of my country's 4th National Nutrition Survey show that approximately one in two Chinese residents is iron-deficient, and one in four suffers from iron-deficiency anemia. Vegetarians, in particular, are very susceptible to iron-deficiency anemia. When iron is deficient, the body tends to burn less fat, making it harder to lose weight.

Many women have misconceptions about iron supplementation. Iron obtained through food is generally divided into two types: heme iron and non-heme iron. Heme iron is the most easily absorbed type of iron, generally found in animal products such as pork, beef, lamb, and animal liver, with an absorption rate of 20% to 25%. Non-heme iron has a much lower absorption rate, only 3% to 5%, and is generally found in plant-based foods such as spinach and soybeans. This explains why vegetarians, even after consuming large amounts of iron-rich vegetables like soybeans and spinach, can still develop iron-deficiency anemia.

Furthermore, plant-based foods contain anti-nutrients such as oxalic acid, lectins, and phytic acid. These anti-nutrients inhibit iron absorption, further reducing the body's utilization of iron. For example, while spinach contains non-heme iron, it also contains a large amount of oxalic acid. Additionally, people with anemia should reduce their tea consumption, as tea also contains a certain amount of anti-nutrients. To prevent anemia caused by tea consumption, adding lemon to tea can help, as the vitamin C in lemons enhances iron absorption.

Iron is extremely important for the human body, and neglecting iron supplementation can easily lead to iron deficiency. The most efficient way to supplement iron is by consuming red meat and animal liver. However, vegetarians can consider taking iron-rich nutritional supplements.
