- If you are sedentary (little or no exercise):
[tex]\[
\text{Calorie Calculation} = \text{BMR} \times 1.2
\][/tex]
- If you are lightly active (light exercise/sports 1-3 days/week):
[tex]\[
\text{Calorie Calculation} = \text{BMR} \times 1.375
\][/tex]
- If you are moderately active (moderate exercise/sports 3-5 days/week):
[tex]\[
\text{Calorie Calculation} = \text{BMR} \times 1.55
\][/tex]
- If you are very active (exercise/sports 6-7 days a week):
[tex]\[
\text{Calorie Calculation} = \text{BMR} \times 1.725
\][/tex]
- If you are extra active (very hard exercise/sports & physical job or 2x training):
[tex]\[
\text{Calorie Calculation} = \text{BMR} \times 1.9

Daily Caloric Needs to Maintain Current Weight:

[tex]\[
\text{BMR} \times \text{activity level} = \text{daily caloric needs to maintain current weight}
\][/tex]

A slight caloric deficit is required for weight loss. Do not exceed more than a 500-calorie deficit per day until you've reached your weight loss goals. Once you've reached your goal weight, you will need to recalculate the above formulas.

Protein Intake (15% of total calories):

[tex]\[
\text{daily caloric intake} \times 0.15 = \text{protein in calories}
\][/tex]

Carb Intake (60% of total calories):

[tex]\[
\text{daily caloric intake} \times 0.60 = \text{carbs intake in calories}
\][/tex]

Fat Intake (25% of total calories):

[tex]\[
\text{daily caloric intake} \times 0.25 = \text{fat intake in calories}
\][/tex]



Answer :

Sure! Let's break down the steps to find the daily caloric needs and macronutrient intake based on different activity levels and then calculate the intake of protein, carbohydrates, and fats for a moderately active person.

### Given:
Basal Metabolic Rate (BMR) = 1500 calories

#### Step 1: Calculate daily caloric needs based on activity levels

1. Sedentary (little or no exercise)
[tex]\[ \text{Calorie-Calculation} = BMR \times 1.2 \][/tex]
[tex]\[ \text{Calorie-Calculation} = 1500 \times 1.2 = 1800 \text{ calories} \][/tex]

2. Lightly active (light exercise/sports 1-3 days/week)
[tex]\[ \text{Calorie-Calculation} = BMR \times 1.375 \][/tex]
[tex]\[ \text{Calorie-Calculation} = 1500 \times 1.375 = 2062.5 \text{ calories} \][/tex]

3. Moderately active (moderate exercise/sports 3-5 days/week)
[tex]\[ \text{Calorie-Calculation} = BMR \times 1.55 \][/tex]
[tex]\[ \text{Calorie-Calculation} = 1500 \times 1.55 = 2325 \text{ calories} \][/tex]

4. Very active (exercise/sports 6-7 days a week)
[tex]\[ \text{Calorie-Calculation} = BMR \times 1.725 \][/tex]
[tex]\[ \text{Calorie-Calculation} = 1500 \times 1.725 = 2587.5 \text{ calories} \][/tex]

5. Extra active (very hard exercise/sports & physical job or 2x training)
[tex]\[ \text{Calorie-Calculation} = BMR \times 2 \][/tex]
[tex]\[ \text{Calorie-Calculation} = 1500 \times 2 = 3000 \text{ calories} \][/tex]

#### Step 2: Calculate macronutrient intake for a moderately active person

Let's focus on the moderately active scenario with the daily caloric intake of 2325 calories.

1. Protein Intake (15% of total calories)
[tex]\[ \text{Protein Calories} = \text{daily caloric intake} \times 0.15 \][/tex]
[tex]\[ \text{Protein Calories} = 2325 \times 0.15 = 348.75 \text{ calories} \][/tex]

2. Carb Intake (60% of total calories)
[tex]\[ \text{Carb Calories} = \text{daily caloric intake} \times 0.60 \][/tex]
[tex]\[ \text{Carb Calories} = 2325 \times 0.60 = 1395 \text{ calories} \][/tex]

3. Fat Intake (25% of total calories)
[tex]\[ \text{Fat Calories} = \text{daily caloric intake} \times 0.25 \][/tex]
[tex]\[ \text{Fat Calories} = 2325 \times 0.25 = 581.25 \text{ calories} \][/tex]

### Summary:

- Sedentary: 1800 calories/day
- Lightly Active: 2062.5 calories/day
- Moderately Active: 2325 calories/day
- Very Active: 2587.5 calories/day
- Extra Active: 3000 calories/day

For Moderately Active:
- Protein Intake: 348.75 calories/day
- Carb Intake: 1395 calories/day
- Fat Intake: 581.25 calories/day
