Is drinking a glass of water before exercise beneficial for fat burning

Drinking moderate amounts of water before exercise can indeed help promote fat metabolism. Water intake can increase basal metabolic rate, optimize exercise performance, accelerate the elimination of metabolic waste, maintain body temperature balance, and reduce blood viscosity. Drinking water before exercise can help the body enter a state of efficient metabolism. Adequate water intake can activate lipase activity and promote the breakdown of fat into free fatty acids for energy supply. An increase in body temperature during exercise can accelerate water evaporation, and early hydration can prevent metabolic efficiency decline caused by dehydration. When there is sufficient water, muscle contraction is more coordinated, which helps to prolong exercise time and intensity. Starting exercise 30 minutes after drinking water can allow water to fully participate in the metabolic cycle.

In some special circumstances, it is necessary to carefully control the amount of water consumed. People with weaker gastrointestinal function who drink excessive water may experience discomfort during exercise. Drinking a large amount of water before high-intensity interval training may increase the burden on the stomach. People with kidney disease or edema should adjust their water intake according to medical advice. Drinking too much water before exercising in a low-temperature environment may lead to an imbalance in body temperature regulation. When exercising on an empty stomach in the morning, it is recommended to drink small amounts of water to avoid stimulating the gastrointestinal tract.

It is recommended to adjust the amount of water intake according to the intensity of exercise and the environment, generally using 200-300 milliliters of warm water to avoid stimulating the internal organs with ice water. During exercise, you can replenish about 100 milliliters of water every 15-20 minutes, and choosing warm water containing trace electrolytes is more effective. Maintaining the habit of drinking water scientifically before exercise for a long time, combined with regular aerobic exercise and dietary control, can significantly improve the efficiency of weight loss. It is crucial to replenish lost water and minerals in a timely manner after exercise, and maintain water electrolyte balance for sustained fat burning.
