Water, dietary fiber, and vitamins: essential micronutrients for fat loss and muscle gain

Water – Promotes Body Metabolism

Drinking water properly can indeed make weight loss twice as effective. Water is one of the most easily overlooked nutrients that is crucial for weight loss.

All bodily metabolisms rely on water; it can also enhance satiety, suppress appetite, and reduce food intake; adequate water intake enables the heart to pump blood effectively, and the body's water helps the blood transport oxygen and other essential nutrients to cells.

Also, when we exercise to lose weight, our bodies lose a lot of water through sweating, so we need to replenish fluids promptly to help our energy recover quickly. So, what kinds of water are best for weight loss?

① Homemade salt water: Add a small amount of salt to cooled boiled water; economical and cost-effective.

② Freshly squeezed vegetable juice: Vegetable juice contains a large number of nutrients needed by the human body, as well as rich dietary fiber, which can promote fat breakdown. Most importantly, vegetable juice is very low in calories, which is beneficial for weight loss.

However, it's not recommended to drink energy drinks or carbonated beverages during exercise. Many people view weight loss as a highly ritualistic endeavor, not only wearing professional clothes and shoes but also buying specialized energy drinks like athletes do to replenish their energy during and after exercise. This idea isn't wrong, but it may not be suitable for you. Most energy drinks aren't designed for people who jog for half an hour every day. These drinks usually contain sugar, and based on energy conversion, drinking one can easily negate half an hour of running. Some energy drinks also contain caffeine, which can cause excitement; excessive caffeine can lead to palpitations, nausea, convulsions, and mental abnormalities. Therefore, it's best to avoid energy drinks or carbonated beverages during exercise.

Dietary fiber – promotes intestinal peristalsis

Dietary fiber, primarily derived from plant cell walls, is a nutrient that is not easily digested. It includes cellulose, hemicellulose, resins, pectin, and lignin. Dietary fiber is essential for a healthy diet, playing a vital role in maintaining a healthy digestive system. Adequate fiber intake can also help prevent cardiovascular disease, cancer, diabetes, and other illnesses. Dietary fiber increases intestinal motility, reduces the damage of harmful substances to the intestinal wall, promotes regular bowel movements, reduces constipation and other intestinal diseases, and enhances appetite. Simultaneously, dietary fiber can inhibit the rapid absorption of sugars, thus slowing down the spike in blood sugar.

Food sources of dietary fiber include: brown rice and germinated rice, as well as whole grains such as corn, millet, and barley; root vegetables and seaweed are also rich in dietary fiber, such as burdock, carrots, green beans, red beans, peas, and wakame seaweed. The most serious health risks to people trying to lose weight are cerebrovascular diseases, malignant tumors, and cardiovascular diseases. In addition, diabetes has a higher prevalence among people trying to lose weight, and constipation in the elderly is also a common ailment that troubles them. Therefore, people trying to lose weight should not neglect their dietary fiber intake. The "Chinese Dietary Reference Intakes" recommends that adults consume 25-30 grams of dietary fiber daily.

Vitamins – improve lipid metabolism

Obese individuals often have a relative deficiency of minerals and vitamins in their bodies. This deficiency leads to a significantly higher incidence of hypertension and disorders of glucose, lipid, and hormone metabolism in obese individuals compared to normal individuals. Supplementing with various minerals and vitamins can significantly reduce weight, body fat percentage, blood pressure, and inflammation levels, and can improve lipid metabolism and enhance the body's metabolic rate.

Vitamin A

Vitamin A is a fat-soluble vitamin, mainly found in the liver of marine fish. Vitamin A plays a vital role in maintaining normal vision, the integrity of epithelial tissues, and the healthy growth of skin, bones, teeth, and hair. It also promotes healthy reproductive function. Furthermore, vitamin A helps burn and metabolize fat, as well as protein, and acts as an antioxidant. Foods rich in vitamin A include cod liver oil, milk, carrots, apricots, broccoli, papaya, honey, bananas, eggs, cabbage, shepherd's purse, tomatoes, eggplant, pumpkin, leeks, mung beans, celery, mangoes, spinach, and onions.

B vitamins

Vitamin B₁ – Regulates nerve activity

Vitamin B₁, also known as thiamine or antineuritis factor, is essential for people trying to lose weight. Sufficient amounts of water-soluble vitamins, especially vitamin B₁ (thiamine), are necessary to maintain a good appetite and normal gastrointestinal motility. Vitamin B₁ is a key substance in the body's metabolism of substances and energy, plays a role in regulating the physiological activities of the nervous system, and can maintain appetite, normal gastrointestinal motility, and promote digestion.

Foods rich in vitamin B₁ include grains, legumes, dried fruits, and nuts, with the outer layer of grains being particularly high in vitamin B₁. Therefore, grains should not be ground too finely during processing. Eggs and leafy green vegetables are also good sources of vitamin B₁. The recommended daily intake is 1.3 mg.

Vitamin B₂ – Improves protein utilization

Vitamin B₂, also known as riboflavin, is a water-soluble vitamin that is easily digested and absorbed. It does not accumulate in the body, so it is regularly supplemented through food or nutritional supplements. Vitamin B₂ participates in biological oxidation and energy metabolism in the body, playing an important role in the metabolism of carbohydrates, proteins, nucleic acids, and fats. It can improve the body's utilization of protein, promote growth and development, maintain the integrity of skin and cell membranes, and has functions such as protecting skin, hair follicles, and mucous membranes, eliminating oral and lingual inflammation, and improving vision.

Food sources of vitamin B₂ include dairy products, eggs, fish, meat, grains, fresh vegetables, and fruits. As long as one maintains a balanced diet, people trying to lose weight generally will not be deficient in vitamin B₂. It is recommended that men trying to lose weight consume 1.4 mg daily, and women consume 1.2 mg daily.

Vitamin B₆ – Stabilizes the nervous system

Vitamin B₆ is essential for the production of antibodies and red blood cells. It not only aids in the metabolism of proteins, fats, and carbohydrates, but also helps convert amino acids, forming new red blood cells, antibodies, and neurotransmitters. It also regulates body fluids, stabilizes the nervous system, maintains normal skeletal and muscular function, and has a diuretic effect.

Vitamin B₆ is widely available in foods, found in both plant and animal sources, such as leafy green vegetables, soybeans, brown rice, eggs, oats, peanuts, and walnuts. However, excessive or prolonged consumption of vitamin B₆ by those trying to lose weight can lead to dependence; therefore, a daily intake of 2 mg is recommended.

Vitamin B₁₂ – Prevents anemia

Vitamin B₁₂ is one of the essential building blocks for blood production in the human body, and it is the only vitamin containing the metallic element cobalt. It helps prevent anemia and maintain the health of the nervous system, can alleviate irritability and anxiety, improve concentration, and enhance memory. Vitamin B₁₂ is also an important nutrient for the human body, participating in various metabolic processes and effectively preventing diseases such as Alzheimer's disease and depression, playing a vital role in maintaining good health.

Vitamin B₁₂ is mainly derived from animal-based foods, including animal organs, fish, poultry, shellfish, eggs, milk and dairy products. Small amounts of vitamin B₁₂ are also found in various fermented foods. The recommended daily intake of vitamin B₁₂ for people trying to lose weight is 2.4 micrograms.

Vitamin C

Vitamin C is a water-soluble vitamin, widely found in fruits and vegetables, but it is easily destroyed by changes in the external environment and is readily lost. Vitamin C is well-known for its skin-beautifying effects, as it is involved in capillary formation, muscle and bone formation. Vitamin C has multiple functions in human metabolism, promoting the synthesis of proteins, especially collagen and other binding substances in connective tissue. It can promote wound healing, enhance the body's disease resistance, and plays an important role in maintaining the normal function of teeth, bones, blood vessels, and muscles. Simultaneously, vitamin C can promote iron absorption, improve anemia, enhance immunity, and combat stress.

Vitamin C is primarily found in fresh vegetables and fruits. Among fruits, citrus fruits, strawberries, kiwis, and dates are particularly high in vitamin C; among vegetables, tomatoes, bean sprouts, cabbage, and green peppers are among the best sources. Other vegetables also contain relatively abundant vitamin C, with leafy parts containing more than stems, and new leaves containing more than older leaves. Leaves that undergo photosynthesis have the highest vitamin C content. People trying to lose weight must obtain vitamin C from their diet. It is recommended that people trying to lose weight consume 100 mg of vitamin C daily.
