Verified step by step guidance

1. Begin by understanding the concept of 'weight set point'. This is the theory that the body has a certain weight range that it naturally tries to maintain, which is regulated by biological mechanisms.
2. Next, consider the term 'metabolism'. Metabolism refers to the chemical processes that occur within a living organism in order to maintain life, including converting food to energy.
3. Examine 'basal metabolic rate'. This is the rate at which the body uses energy while at rest to maintain vital functions such as breathing and keeping warm.
4. Understand 'body mass index' (BMI). BMI is a measure of body fat based on height and weight that applies to adult men and women.
5. Finally, compare these concepts to determine which one aligns with the idea of the body maintaining a specific weight. The 'weight set point' is the concept that directly relates to the body's attempt to maintain a particular level of body weight.
