1. Estimate daily energy needs for an active 60 kg woman and a 70 kg sedentary man.

Question

UpStudy AI · Accepted Answer

To estimate daily energy needs, we can use the Mifflin-St Jeor equation, which is a widely used method for calculating Basal Metabolic Rate (BMR) and then adjusting for activity level to find Total Daily Energy Expenditure (TDEE).

### Mifflin-St Jeor Equation

For women:
$$ \text{BMR} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (years)} - 161 $$

For men:
$$ \text{BMR} = 10 \times \text{weight (kg)} + 6.25 \times \text{height (cm)} - 5 \times \text{age (years)} + 5 $$

### Activity Level Multipliers
- Sedentary (little or no exercise): BMR × 1.2
- Lightly active (light exercise/sports 1-3 days/week): BMR × 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): BMR × 1.55
- Very active (hard exercise/sports 6-7 days a week): BMR × 1.725
- Super active (very hard exercise/physical job & exercise 2x/day): BMR × 1.9

### Estimation for the 60 kg Active Woman
Assuming an average height of 165 cm and age of 30 years (you can adjust these values based on specific information):

1. **Calculate BMR:**
   $$
   \text{BMR} = 10 \times 60 + 6.25 \times 165 - 5 \times 30 - 161
   $$
   $$
   \text{BMR} = 600 + 1031.25 - 150 - 161 = 1320.25 \text{ kcal/day}
   $$

2. **Adjust for activity level (active):**
   $$
   \text{TDEE} = \text{BMR} \times 1.55 \quad (\text{Moderately active})
   $$
   $$
   \text{TDEE} = 1320.25 \times 1.55 \approx 2046.39 \text{ kcal/day}
   $$

### Estimation for the 70 kg Sedentary Man
Assuming an average height of 175 cm and age of 30 years:

1. **Calculate BMR:**
   $$
   \text{BMR} = 10 \times 70 + 6.25 \times 175 - 5 \times 30 + 5
   $$
   $$
   \text{BMR} = 700 + 1093.75 - 150 + 5 = 1648.75 \text{ kcal/day}
   $$

2. **Adjust for activity level (sedentary):**
   $$
   \text{TDEE} = \text{BMR} \times 1.2
   $$
   $$
   \text{TDEE} = 1648.75 \times 1.2 \approx 1978.5 \text{ kcal/day}
   $$

### Summary of Daily Energy Needs
- **Active 60 kg woman:** Approximately **2046 kcal/day**
- **Sedentary 70 kg man:** Approximately **1979 kcal/day**

These estimates can vary based on individual factors such as age, height, and specific activity levels.
- Active 60 kg woman: 2046 kcal/day - Sedentary 70 kg man: 1979 kcal/day

Estimate daily energy needs for an active 60 kg woman and
a 70 kg sedentary man.
