Myth 2: ‘Being overweight isn’t that bad for you’
The adolescent period is associated with changes in eating and activity behaviors in girls. Less reliance on parental provision and choice of food, coupled with a decrease in participation in physical activity and sport, can create an energy imbalance, predisposing to weight gain. Physiological alterations to body composition, reduction in insulin sensitivity, and psychological adjustments may further amplify the risk of becoming overweight and maintaining an unhealthy level of body fat into childbearing years. During pregnancy excess body fat is a risk factor for poor pregnancy outcomes and may predispose an infant to a lifelong heightened risk of being overweight and developing chronic disease.
A s far back as I can remember, I was overweight. In my teenage years, I tried every diet going, and would sometimes lose weight, only to put it all on again. It would mean a life of permanent hunger. And I was physically fit. I decided to set other priorities in my life; I trained as a psychotherapist, got married and started renovating an old house. At the age of 30, I tipped the scales at kg 23st 8lb. If asked, I told people I was comfortable with my weight and that my only wish, if anything, was to be a bit fitter. But at that same time, I was secretly visiting an obesity clinic as an outpatient and thinking about a stomach-stapling operation.
