2. MEAL PLANNING:
"Meal planning involves
strategicallyselecting and
organizing meals to
ensurethey meet individual
dietary needs andgoals."

3. FACTORS TO BE
CONSIDERED:
1. Caloric intake
2. Macronutrient balance
(protein, carbohydrates, fats)
3. Micronutrient adequacy
(vitamins, minerals)

4. PRINCIPLES OF MENUPLANNING:
1. Individualization
2. Long-Term Sustainability
3. Variety
4. Nutrient Density
5. Economic Consideration
6. Seasonal Availability
7. Food Preferences

5. 8. Fasten Recovery
9. Satiety
10. Satisfaction
11. Portion Control
12. Meal Timing
13. Hydration
14. Food Safety
15. Palatable

7. FUNDAMENTAL CALCULATIONS INVOLVED
1.CALCULATION OF CALORIES:
Factors such as age, gender, weight, height, health
condition and activity level are taken into account.
One common method for calculating caloric needs
is the Harris-Benedict equation, which provides an
estimate of basal metabolic rate (BMR) based on
gender, age, weight, and height.
Activity factors are then applied to this value to
determine total daily energy expenditure (TDEE).

8. 2.MACRONUTRIENT DISTRIBUTION CALCULATION:
•Calculating the distribution ofmacronutrients
ensures that individuals consume an
appropriate balance of nutrients.
•The recommended distribution of
macronutrients varies based on factors such as
age, gender, activity level, and health goals.
•For example, a general guideline might suggest
that 45-65% of total calories come from
carbohydrates, 10-35% from protein, and 20-
35% from fats.

9. 3. PORTION SIZE CALCULATION:
•Portion size refers to the amount of
food served or consumed at a single
sitting
•Portion size calculations help individuals
understand appropriate serving sizes for
different types of foods.
•Visual cues, hand measurements, or
kitchen tools can be used to estimate
portion sizes.

10. 4.RECIPE SCALING CALCULATION:
•Recipe scaling allows individuals to adjust
ingredient quantities to accommodate different
serving sizes or to meet specific nutritional
goals.
•This calculation ensures consistency in
nutritional content and flavor when modifying
recipes.
•Recipe scaling involves adjusting ingredient
quantities proportionally based on the desired
number of servings.

GUIDE TO THE
BASIC
CALCULATIONS"

12. ASSESS NUTRITIONAL NEEDS
•Determine the nutritional needs
of the individuals for whom the
menu is being planned.
•Consider factors such as age,
gender, weight, height, activity
level, and any specific dietary
requirements or restrictions.

13. 2. CALCULATE TOTAL DAILY CALORIC
NEEDS:
•Use a formula such as theHARRIS-
BENEDICT EQUATION to calculateeach
individual's basal metabolic rate (BMR)
based on theirgender, age, weight, and
height.
•Then, apply an activity factor toestimate
their TOTAL DAILY ENERGY EXPENDITURE
(TDEE).

14. BMR (Basal Metabolic Rate)
•It's the amount of energy your body
needs to maintain basic
physiological functions while at rest,
such as ; breathing, circulating
blood, regulating temperature, and
cell production.
•It's often used as a baseline for
calculating calorie needs for weight
management and nutrition planning.

15. BMR VALUES
BMRformen:
•66.5+(13.75×weightinkg)+(5.003×heightin
cm)−(6.755×ageinyears)
BMRforwomen:
•655.1+(9.563×weightinkg)+(1.850×heighti
ncm)−(4.676×ageinyears)

16. ACTIVITY FACTORS

17. 3. DETERMINE MACRONUTRIENT
DISTRIBUTION:
•Based on dietary guidelines and
individual preferences, decide on the
distribution of macronutrients
(carbohydrates, proteins, fats) in the
menu.
•For example, a balanced diet might
consist of approximately 45-65% of total
calories from carbohydrates, 10-35%
from protein, and 20-35% from fats.

18. 4.CALCULATE MACRONUTRIENT GOALS
•Convert the percentage of
calories from each
macronutrientinto grams based
on the individual's total daily
caloric needs.

19. 5. PLAN MEALS
•Based on the calculated total daily
caloric needs and macronutrient goals,
create a menu that includes breakfast,
lunch, dinner, and snacks.
•Ensure that each meal contains a
balance of carbohydrates, proteins, and
fats, as well as a variety of nutrient-dense
foods such as fruits, vegetables, whole
grains, lean proteins, and healthy fats.

20. 6. ADJUST PORTION SIZES
•Use portion size guidelines to ensure
that each mealprovides the
appropriate number of calories
andmacronutrients.
•Adjust portion sizes as needed to
accommodate individualpreferences
and dietary goals.

21. 7. MONITOR AND ADJUST
•Regularly monitor the menu plan
to ensure that it meets
nutritional needs and supports
health goals.
•Make adjustments as necessary
based on feedback, changes in
dietary requirements, or new
nutritional guidelines.

22. Let's
Discuss An
Example

23. EXAMPLE
“A one-day weight loss diet plan for a 19
year old female with Diabetes Mellitus.”
DATA :
•Age: 19 years
•Gender: Female
•Weight: 75 kg
•Height: 151 cm (about 4.95 ft)
•BMI: 32.9 (Obese)
•Activity level: Sedentary

24. “ESTIMATING TOTAL CALORIES PER DAY
(kcal/day)”
STEP 1 : Calculate BMR;
For women: BMR = 447.593 + (9.247 ×weight in kg) + (3.098 ×
height in cm) -(4.330 ×age in years)
BMR= 447.593+(9.247 ×75) + (3.098 ×151) -(4.330 ×19)
= 447.593+693.525 +467.798-82.27
=1,527

25. •STEP2 : Determine the Activity Level
The activity level of this female is sedentary i.e
very little or no exercise.
•STEP 3: Calculating TDEE (Total Daily Energy
Expenditure)
Multiply BMR by activity factor
Activity Level =Sedentary (little or no exercise):
BMR × 1.2
=1,527 × 1.2
=1,832.4

26. STEP 4: Determine Caloric Intake for
WeightGoals
we’ll create a calorie deficit (consume fewer calories
than TDEE).
•Caloric Deficit=TDEE−Calories Consumed
•If Total Energy Expenditure (TEE) is 1832.4 calories
per day, aiming for a daily caloric intake of around
1332.4 calories (1832.4 - 500) could be a
reasonable goal for weight loss.

28. STEP :1 Calculating calories and grams for
carbohydrates, fats andproteins.
•Carbohydrates: 45%
0.45×1332.4 calories from carbohydrates
•Fats: 30%
0.30×1332.4 calories from fats
•Proteins: 25%
0.25×1332.4 calories from proteins
•Carbohydrates: 0.45×1332.4 = 599.58 calories
•Fats: 0.30×1332.4=399.72 calories
•Proteins : 0.25×1332.4=332.1 calories

29. •Carbohydrates:
599.58calories / 4calories/g = 149.9grams
•Fats:
399.72calories /9calories/g = 44.4grams
•Proteins:
332.1calories /4calories/g = 83grams
Therefore, one balanced distribution of 1332.4
calories could be approximately 150g of
carbohydrates, 44g of fats, and 83g of proteins.
