The BEST thing for Lamar to do to determine if he should attempt to lose weight is to examine his calculated Body Mass Index (BMI).
BMI is a useful tool that helps assess whether an individual has a healthy body weight for their height. It provides a standard measure that can indicate whether someone is underweight, normal weight, overweight, or obese. While it is not a perfect measure and doesn’t account for muscle mass, fat distribution, or overall health, it is a good starting point for evaluating weight-related health concerns.
Asking friends or comparing himself to peers may provide subjective opinions, and looking in the mirror might lead to a skewed perception based on personal biases. Hence, using BMI is the most objective approach for this assessment.
