Body Mass Index (BMI) is a measure used to evaluate whether a person is underweight, normal weight, overweight, or obese. In the context of health, especially concerning men, a very low BMI can indicate severe undernourishment and potential health risks. Here is how to determine the "Lethal" BMI in men:
1. Understanding BMI Levels: Generally, a BMI below 18.5 is considered underweight, with increasing risk as the BMI decreases further.
2. Lethal BMI Definition: A lethal BMI refers to a threshold where the BMI is so low that it poses significant immediate health risks or life-threatening consequences.
3. Correct Determination: Among the given options, a BMI of 13 is widely recognized in medical guidelines as a critical threshold for potentially life-threatening health risks in men due to severe undernutrition.
Therefore, the correct answer to the question of what BMI is considered "Lethal" in men is 13.
