© British Nutrition Foundation 2010 Overview What is energy? Energy balance: In vs. Out

© British Nutrition Foundation 2010 What is energy? 1kJ = 1000J 1MJ = 1000kJ 1kcal = 4.18kJ The power to do work, or produce heat or light. Measured in kilojoules (kJ) or megajoules (MJ).

© British Nutrition Foundation 2010 Energy from food Carbohydrate (16kJ/g) Protein (17kJ/g) Fat (37kJ/g) Macronutrients:

© British Nutrition Foundation 2010 Alcohol? 1 gram of alcohol provides 29kJ.

© British Nutrition Foundation 2010 Nutrient contribution to energy

© British Nutrition Foundation 2010 Energy intakes Estimated Average Requirements (EARs)

© British Nutrition Foundation 2010 Question If we include alcohol in our diet, provision of energy from which macronutrient should decrease?

© British Nutrition Foundation 2010 Energy needs vary Basal metabolic rate (BMR) - Age - Sex - Body size/composition Level of physical activity

© British Nutrition Foundation 2010 Basal metabolic rate (BMR) Rate of energy use to maintain basic functions of the body. Accounts for 75% of an individual’s energy needs. Men usually have a higher BMR than women.

© British Nutrition Foundation 2010 Physical activity levels (PAL) Intensity and duration. Children and young people: at least 60 mins (every day). With activities for bone strength, muscle strength and flexibility. Adults: at least 30 mins (5 times per week). Energy expenditure = BMR x PAL

© British Nutrition Foundation 2010 Why do men have higher BMRs? a.Men tend to have more muscle. b.Men tend to be bigger. c.Both of the above. d.Men tend to be more active. e.All of the above.
