Introduction to energy © IGD 2017 UPDATED NOV 2017 1
What is energy?
Energy is provided by the food and drinks we consume.
Energy is needed by the body to stay alive. It is needed for growth
and repair, as well as to perform basic functions and physical
activity. To maintain our bodyweight the energy we consume needs
to equal the energy we expend, to lose weight we either need to
consume less or move more.
Energy is measured in calories (kcal) or kilojoules (kJ) and this is
what is displayed on food and drink labels.

Where does our energy come from?
Different food and drinks provide different amounts of energy.
Energy is measured in units of kilocalories (kcal) or kilojoules (kJ).
Nutrient Energy per gram
Fat 9 kcal (37 kJ)
Protein 4 kcal (17 kJ)
Carbohydrate 4 kcal (17 kJ)
Fibre 2 kcal (8 kJ)
Alcohol 7 kcal (29 kJ)
The amount of energy a food contains per gram is known as its
energy density so we can describe fat as more energy dense than
protein or carbohydrate.

Why do we need to Many of us are eating too much and not being active
enough.
reduce our calorie
intake? Nearly 2/3 of the adult population in England is overweight or
obese.
When we eat and drink more calories than we use up, our
Recommended
bodies store the excess as body fat.
Energy (kcal) 2500kcal/day (men)
2000kcal/day (women)
Childhood Obesity Plan:
The start of a conversation
14 recommendations, 3 most relevant to industry are:
• Reformulation: A reduction in the sugar content of products that contribute
to children’s sugar intake by 20% by 2020, (5% reduction in year 1)
• ‘Sugar Tax’: Soft drinks industry levy on sugar-containing soft drinks from
2018 across the UK (levy invested in programmes to reduce obesity)
• Labelling: Consideration of sugar labelling on products
There are average and maximum calorie or portion size guidelines for products that
are likely to be consumed at one time, which sit alongside the sugar reduction
targets.
PHE are clear that sugar reduction should be achieved without increasing the level
of saturated fat within a product and, where possible, be accompanied by calorie
reduction

In 2018, PHE will publish the evidence for the calorie reduction
programme to remove excess calories from the foods children
consume the most.
Adults currently consume on average between 200 to 300 calories too
many each day and children are following suit.
Reducing calorie consumption is critical to reversing the obesity trend,
which shows:
• 1 in 3 children are overweight or obese by the time they leave
primary school
• More children in the UK are being diagnosed with type 2 diabetes
• Children from disadvantaged backgrounds are more likely to be
obese

Approach Technology Pros Cons
Remove Remove high energy Simple, quick to achieve, little Will change the sensory characteristics
ingredients such as investment required
the skin and visible May not be possible as will change the product too
fat from meat Could result in savings on ingredients much
Reduce Reduce sugar Can be cost effective Can take time as consumers need to be taken on
the journey
May not take too much investment in
processing and technologies May reach an end point where no further
reductions can be made - sensory characteristics
will be compromised
Technical challenges
Replace Use lower fat Simple and cost effective May affect sensory characteristics
ingredients to lower
the energy density of May not alter product process too Greater quantity of lower saturated fat ingredients
a product drastically may be required to achieve the same result
Portion size Factory changes Actively encouraged by PHE Ensure it is the appropriate approach for your
product and target consumer
