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
- Calculate your ideal weight as per your height from the table given at the end of this question.
- An active child should eat around 55.11 calories for each kilogram desired weight.
- 55 per cent of calories should come from carbohydrates. There are 4 calories in each gram of carbohydrates.
- 15 per cent of your calories should come from proteins. There are 4 calories in each gram of proteins.
- 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
- Ideal weight = 40 kg.
- The number of calories needed = 40 × 55.11 = 2204.4
- 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) - 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. - 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.
