Why is drinking cold water not allowed for weight loss

It is not recommended to drink cold water during weight loss mainly due to factors such as gastrointestinal function inhibition and decreased metabolic efficiency. Cold water may stimulate the gastrointestinal mucosa, leading to weakened digestive function and affecting nutrient absorption. At the same time, low temperature can cause a temporary decrease in basal metabolic rate, which is not conducive to fat breakdown. It is recommended to drink warm water during weight loss to help maintain normal metabolic levels. Cold water entering the digestive tract can cause local vasoconstriction and slow down gastrointestinal motility. The activity of digestive enzymes is significantly reduced in low-temperature environments, which may lead to incomplete digestion of food, especially fatty substances. Some people may experience discomfort symptoms such as bloating and diarrhea after drinking cold water, which can interfere with their normal diet plan. Cold water stimulation may also trigger false hunger and increase the probability of unnecessary snacking. When the core temperature of the human body is maintained at around 37 degrees Celsius, metabolic enzymes work most efficiently. After drinking cold water, the body needs to expend energy to heat the water temperature to body temperature. This process does indeed consume a small amount of heat, but compensatory thermogenesis reactions will simultaneously reduce energy consumption in other parts. Continuous consumption of cold water may lead to a decrease in basal metabolic rate, which in turn reduces daily total calorie expenditure. Some traditional Chinese medicine theories suggest that cooling water can lead to the accumulation of dampness in the body, affecting the balance of water and fluid metabolism.

During weight loss, it is recommended to maintain a daily intake of 1500-2000 milliliters of warm water, and to drink in small portions for better results. It is recommended to choose light salt water at 25-35 degrees Celsius for hydration after exercise, and avoid drinking chilled drinks immediately. People with digestive diseases such as gastric ulcers and irritable bowel syndrome must strictly avoid cold water stimulation. If you experience persistent abdominal pain or indigestion after drinking cold water, you should seek medical attention promptly to check for organic diseases.
