Teenagers

What would happen if ?????

A male teenager constantly consumes 2500 kcal every day for a year. Hint: 284.4kcal per day more than his needs Or 103,806kcal per year more than his needs.

2. A female child constantly consumes 1500kcal every day for six months. Hint: 242.11kcal per day less than her

needs

Or 44,064kcal

per

six months less

than

her needs

Nutrient density

identifies the proportion of nutrients in foods, with terms such as nutrient rich and micronutrient dense referring to similar properties. Nutrient Dense -- -- Nutrient Rich

Calorie Dense Foods

Calorie density is how much energy, i.e. calories, is provided per unit measure of food. In comparison, calorie-dense

foods, such as fat and refined sugars, provide many calories in a small amount of food.

How many calories should we have at each meal ?

Discussion Points The average female teenager should have 1893 kcal3 main meals per day @ 631 kcal Is this achievable? Would it be easy to monitor?

What suggestions could you give to a teenager?

Lets look at CALORIES in everyday foods that we eat.
