Verified step by step guidance

Understand the concept of energy balance: Energy balance refers to the relationship between the calories consumed (caloric intake) and the calories expended (caloric expenditure) by the body. It is a fundamental principle in metabolism and weight management.

Clarify the terms 'positive energy balance' and 'negative energy balance': A positive energy balance occurs when caloric intake exceeds caloric expenditure, leading to weight gain. Conversely, a negative energy balance happens when caloric expenditure exceeds caloric intake, resulting in weight loss.

Evaluate the statement 'Energy balance is unrelated to metabolic rate': This is incorrect because metabolic rate directly influences caloric expenditure, which is a key component of energy balance.

Analyze the statement 'Energy balance is achieved when caloric intake equals caloric expenditure': This is correct because when caloric intake matches caloric expenditure, the body maintains its current weight, achieving energy balance.

Review the remaining statements: 'A negative energy balance results in weight gain' and 'A positive energy balance leads to weight loss' are both incorrect based on the definitions provided earlier. Negative energy balance leads to weight loss, and positive energy balance leads to weight gain.
