FOR
TEENS - Why do people gain weight? |

Reasons
for gaining weight
Predictably,
people cited overeating and drinking are the
main reasons. The reasons behind this, though,
were complex and interesting:
* boredom
* depression
* comfort
* constant availability of food (including
convenience foods)
* bad eating habits
* eating at the wrong time
* always finishing all the food on the plate
* rewarding behavior with sweet treats, and
nurturing through food
* snack eating
* eating the wrong foods
* 'healthy' food is more expensive
Lack of exercise was also cited, with the
reasons behind it including:
* laziness/too
tired after work
* sedentary leisure activities (eg watching
television, computer games)
* unable to exercise because of injury, or
just too big
* prohibitive cost of health clubs/exercise
classes
* being housebound
Health professionals
They gave broadly similar reasons for the
prevalence of overweight as the general public,
but also cited other reasons:
* poverty
* poor nutrition education
* poor literacy
* poor labelling of products by both manufacturers
and supermarkets
* lack of availability of fruit and vegetables
in some (particularly urban) areas
* lack of traditional cooking skills
Major reasons
The appetite
is also geared for survival and has been set
to prevent weight loss. When there are excess
calories available, appetite promotes weight
gain by ensuring that the individual will
rather eat ‘too much’ than ‘too
little’. Matching Energy Intake and
Energy Expenditure is therefore extremely
difficult. A small mismatch of, for example,
1% can lead to the accumulation of 10 000
Calories per year, resulting in a weight gain
of 1-2 kg per annum.
‘Survival of the
fittest’ ensured that only the most
efficient energy hoarders and biggest eaters
survived, thereby passing these genetic qualities
on to future generations.
