How much water should an individual drink for every pound lost during exercise?

1. 8 fl. oz

2. 12 fl. oz

3. 16 fl. oz

4. 24 fl. oz

The correct answer is: 16 fl. oz

The recommended amount of water to drink for every pound lost during exercise is approximately 16 fluid ounces. This guideline is based on the principle that for each pound of body weight lost, there is a significant amount of fluid that needs to be replenished to maintain hydration levels and support physiological functions. When exercising, especially in hot and humid conditions, individuals can lose considerable amounts of fluid through sweat. Replenishing this lost fluid is crucial to prevent dehydration, maintain performance, and promote recovery. Therefore, consuming 16 fluid ounces for every pound lost helps ensure that the body receives adequate hydration after exertion. In contrast, lower amounts like 8, 12, or 24 fluid ounces may not fully replace the fluids lost, which could lead to inadequate hydration or excessive fluid intake, both of which can have negative effects on health and performance.
