Final answer:
A deficit of approximately 3,500 kilocalories (kcal) results in the loss of 1 lb of body weight, which represents the energy stored in one pound of body fat. the answer to the student's question is B) 3,500 kcal. Reducing or expending an extra 3,500 kcal beyond what you consume will result in a loss of approximately 1 lb of body weight.ds to be created by either consuming fewer calories, increasing physical activity, or a combination of both.
Step-by-step explanation:
When considering the relationship between calorie intake and weight loss, it is essential to understand that weight management is influenced by the balance between calories consumed and calories expended. A reduction or energy expenditure to lose 1 lb of body weight is generally equated to a deficit of approximately 3,500 kilocalories (kcal). This value is based on the estimation that one pound of body fat stores about 3,500 kcal worth of energy.
The concept of energy balance can be summarized as follows: if the amount of calories you consume through food and drink is equal to the calories your body uses up through daily activities and metabolic processes, your weight will remain stable. To lose weight, you must consume fewer calories than your body uses, creating a calorie deficit.
Therefore, the answer to the student's question is B) 3,500 kcal. Reducing or expending an extra 3,500 kcal beyond what you consume will result in a loss of approximately 1 lb of body weight.
