Losing weight and keeping it off is often seen as a simple question
of “energy in and energy out” – how much you eat and how much you
move. But science has proven that obesity has many causes, some of
which are beyond the awareness or control of the person living with obesity.1
“I go to the gym, I eat very small portions, I do yoga. But I am
still overweight. People will say to me ‘eat less, move more and you
will be fine’. But it is really not that simple”.
For Vicki Mooney, a mother of three living in Spain, asking for help
from her doctor was a turning point in her life. It also made her
realise that her obesity is not a simple matter of lifestyle but
rather a chronic disease with many causes.
Anyone who has been through even a fraction of what Vicki has, knows
it far too well – losing weight is difficult. Keeping the pounds off
afterwards even more so. Still, it seems to be a widespread belief
that people who live with obesity are entirely responsible for their situation.
The popular narrative implies that if only we ate the right food and
exercised in the right way, we would not carry excess weight. While
this mechanism of energy in and energy out is true, it’s a dramatic
simplification – and hurtful to those affected by obesity. Losing
weight does depend on the balance between how much energy we eat, and
how much energy we use. But the causes of the energy imbalance are
complex and vary from person to person.2
Instead, leading scientists agree that people who
struggle with excess weight might in fact be living with obesity,
which is a chronic disease.2
Just like many other chronic diseases, obesity develops over a period
of time. There are many reasons for this, some of which are beyond our
conscious awareness or control. Our psychology, genetics, hormones,
stress levels, the quantity and quality of our sleep, the medications
we take and the environment we live in, can all play a role. 1,2
To effectively manage obesity, the first step is to identify which
causes are playing a role – these causes will vary from person to
person – and how some of the roadblocks can be addressed.1,2
