I posted this question yesterday and I

got confused.

The determinant of total energy requirement that may most appropriately
be manipulated in a weight loss program
is:

1. basal metabolic rate
2. physical activity
3. dietary thermogensis
4. body temperature

Is the correct answer #1
basal metabolic rate?

No. you cannot manipulate that. You can however, change physical activity.

I asked you yesterday if the right answer would maybe be 2 or 3.
The right answer is physical activity?

Lana, I don't know what your question means. Bobpursley clearly stated that 2 (physical activity) is the answer, right?

??

I recommend you reread what I posted yesterday, and today. There are some serious reading comprehension issues going on here.
Do you understand 1 and 3? You really ought to understand those and why they are wrong. Basal means basal: life functions. Thermogenesis? You need to understand how that is related to basal metabolism also. One cannot change basal metabolism unless one stops breathing.

I apologize for any confusion caused. Let me explain the answer in more detail.

In the context of weight loss, the determinant of total energy requirement refers to the factor that can be manipulated or changed to achieve weight loss.

1. Basal metabolic rate (BMR) is the amount of energy your body needs to maintain basic physiological functions at rest, such as breathing, circulation, and cell production. BMR is influenced by factors like age, sex, height, weight, and body composition. However, BMR cannot be easily manipulated in a weight loss program.

2. Physical activity refers to any movement or exercise that you engage in throughout the day. This includes activities like walking, running, swimming, or any other form of exercise. By increasing physical activity, you can burn more calories and create a calorie deficit, leading to weight loss.

3. Dietary thermogenesis refers to the energy required for the digestion, absorption, and metabolism of food. It accounts for a small proportion of total energy expenditure. While you can slightly increase dietary thermogenesis by consuming certain foods (such as protein-rich foods), it has a minimal impact on overall weight loss.

4. Body temperature does not directly play a significant role in determining the total energy requirement in a weight loss program. Changes in body temperature (within normal range) do not have a substantial impact on energy expenditure or weight loss.

Therefore, the correct answer to the question is #2, physical activity. By increasing physical activity levels, you can burn more calories and create an energy deficit, which is essential for weight loss.
