When energy intake in the form of food and drink…
…is greater than energy expenditure
![Page 5: Healthy weight – addressing the challenges of childhood and adult obesity](https://reader036.vdocuments.site/reader036/viewer/2022081520/56814e8f550346895dbc3428/html5/thumbnails/5.jpg)
Causes
• Lack of exercise
• Poor diet
• It develops gradually: poor diet & lifestyle choices
• Increased access to poor food

Causes
• Too much sugar
• The introduction of mass production of high-fructose corn syrup

Foresight 2007
• Complex web of societal and biological factors…
• …over 100 variables that directly or indirectly influence..

Why does it matter?
Compared with a non-obese man, an obese man is:
• 5 x more likely to develop type 2 diabetes
• 3 x more likely to develop cancer of the colon
• 2 ½ x more likely to develop high blood pressure
![Page 11: Healthy weight – addressing the challenges of childhood and adult obesity](https://reader036.vdocuments.site/reader036/viewer/2022081520/56814e8f550346895dbc3428/html5/thumbnails/11.jpg)
Micro Lives
• Life expectancy for 22 yr man = 79– 20,800 days– 500,000 hours– 1 million half hours
• 1 Micro Lives = 30 min
• 1 day = 48 Micro Lives
![Page 12: Healthy weight – addressing the challenges of childhood and adult obesity](https://reader036.vdocuments.site/reader036/viewer/2022081520/56814e8f550346895dbc3428/html5/thumbnails/12.jpg)
Micro Lives
• Bodies age faster when we do bad things to them– So micro lives can also be allocated to risk
• 1 Cigarette shortens life by 15 min
• 1 Micro Life– 2 Cigarettes– 2 Pints Strong Beer
![Page 13: Healthy weight – addressing the challenges of childhood and adult obesity](https://reader036.vdocuments.site/reader036/viewer/2022081520/56814e8f550346895dbc3428/html5/thumbnails/13.jpg)
1 Micro Life
Healthy waist size man = 37 inches– 1 Extra inch on your waist line [every day]
• 39 - 40 inch waist
= 2.3years
= 76.7 life expectancy
![Page 14: Healthy weight – addressing the challenges of childhood and adult obesity](https://reader036.vdocuments.site/reader036/viewer/2022081520/56814e8f550346895dbc3428/html5/thumbnails/14.jpg)

Why does it matter: Children?
• Short term– emotional & psychological effects– low self-esteem; anxiety & depression– Type 2 diabetes
• Once established, notoriously difficult to treat: long term:– higher risk of morbidity, disability &
premature mortality in adulthood

• Is it worth it? – Can society turn obesity around?
• What works and what doesn’t work?
• What else could we do?
