Question

When you design your healthy diet, you want to make sure that you meet the dietary requirements to help you grow into a healthy adult. As you plan your menu, follow the following guidelines

1. Calculate your ideal weight as per your height from the table given at the end of this question.
2. An active child should eat around 55.11 calories for each kilogram desired weight.
3. 55 per cent of calories should come from carbohydrates. There are 4 calories in each gram of carbohydrates.
4. 15 per cent of your calories should come from proteins. There are 4 calories in each gram of proteins.
5. 30 per cent of your calories may come from fats. There are 9 calories in each gram of fat.

Following is an example to design your own healthy diet.

Example

1. Ideal weight = 40 kg.
2. The number of calories needed = 40 × 55.11 = 2204.4
3. Calories that should come from carbohydrates = 2204.4 × 0.55 = 1212.42 calories.
   Therefore, required quantity of carbohydrates = `1212.42/4` = 303.105 g = 300 g. (approx)
4. Calories that should come from proteins = 2204.4 × 0.15 = 330.66 calories.
   Therefore, required quantity of protein = `330.66/4` g = 82.66 g.
5. Calories that may come from fat = 2204.4 × 0.3 = 661.3 calories.
   Therefore, required quantity of fat = `661.3/9` g = 73.47 g.

Answer the Given Questions

1. Your ideal desired weight is ______ kg.
2. The quantity of calories you need to eat is ______.
3. The quantity of protein needed is ______ g.
4. The quantity of fat required is ______ g.
5. The quantity of carbohydrates required is ______ g.

Answer 1

Let the height of a girl student of 7th class be 5 feet.

1. Ideal weight – 45 kg

2. Quantity of calories needed = 45 × 55.11 = 2479.95  calories

3. Calories that should come from carbohydrates

= `(2479.95 xx 55)/100`

= 2479.95 × 0.55

= 1363.97 calories

∴ Required quantity of carbohydrates

= `1363.97/4`g

= 340.99 g 

4. Calories that should come from proteins

= `(2479.95 xx 15)/100`

= 2479.95 × 0.15

= 371.99 calories

∴ Required quantity of protein

= `371.99/4` g

= 92.99 g

5. Calories that may come from fat

= `(2479.95 xx 30)/100`

= 2479.95 × 0.3

= 743.985 calories

∴ Required quantity of fat

= `773.985/9` g

= 85.99 g
