Is Identifying As Overweight Essential For Successful Weight Loss?

When it comes to managing weight, it’s assumed that an important factor is the person being aware that they are overweight. Many public health agencies work off this assumption, aiming to raise awareness of overweight and obesity.

However, there has not been research conducted to explore this assumption. Some suggest it may be doing more harm than good.

 

Background

Actual weight and believed weight status are often inconsistent in people. There are those who believe themselves to be overweight, but they are considered to be a healthy weight. Others who are considered to be overweight do not identify as overweight.

The impact of perceived weight could potentially go both ways. It could be a case of ‘knowledge is power’, allowing someone to make a change. However, it could also have a negative impact on mental health, leading to unhealthy eating habits and psychological distress.

 

The study

This study aimed to explore the evidence about the perception of weight and the relationship to weight loss attempts, weight control strategies, physical activity, eating habits, disordered eating and weight change.

Data from 78 studies was evaluated, taking into account gender, age and objective weight status. Inclusion criteria for the studies included: analysis between the perceived weight status and one or more of the listed variables.

Studies that were published prior to 1991, in a language other than English or that explored clinical or non-general populations were excluded.

 

The findings

Participants that perceived themselves as overweight were more likely to attempt weight loss, using both healthy and unhealthy weight control strategies.

But despite this, they were not more likely to participate in physical activity or healthy eating, two examples of enacting long-term weight control strategies. Furthermore, they were more likely to gain weight over the long-term.

Some groups were also more likely to engage in disordered eating patterns. In particular, females and adolescents were shown to be more likely to have disordered eating behaviours such as bulimic symptoms and binge-eating.

 

Conclusions

Despite assumptions, perception of being overweight was not associated with improved weight management. In fact, the evidence suggested that it was predictive of increase in weight over time. Despite individuals who see themselves as overweight being more likely to report attempting weight loss, they were gaining more weight in the long-term.

This suggests that although those who see themselves as overweight are trying to lose weight, it is not translating into healthy long-term weight maintenance behaviours.

The problem may lie in the stigma of being overweight, and how this impacts on the enactment of healthy habits. People may engage in more extreme measures that actually lead to long-term weight gain.

It may even be that the current approach that public health agencies have of increasing awareness of overweight is actually doing more harm than good. However, more research is needed to support this, and to identify more effective methods of education.
