Creating a Healthy-Weight Environment

Greater attention to factors that affect food intake and physical activity patterns can help create a healthy-weight environment.
Creating a Healthy-Weight Environment

"Environment" is defined as external conditions or surroundings. In terms of achieving a healthy weight, having constructive home and workplace environments is important.

Experts look at the environment that affects food intake and body weight from an evolutionary perspective. To survive, early humans ate food whenever it was available—and periods of abundance and scarcity were the norm. Today, however, we live in a world of food abundance, so the current rates of obesity are not surprising. It is simply a consequence of living in an environment where food is everywhere, and there are few requirements for physical activity.

Researchers believe that greater attention needs to focus on those aspects of the environment that have the greatest impact on food intake and physical activity patterns. In this context, changing the availability and type of foods is important. This includes considering the nutritional composition and portion sizes of foods.1

Foods in the Environment
Numerous studies have looked at environmental factors that affect weight. These include what foods are eaten. For example, eating strategies that limit sweetened beverages and "supersized" portions have been associated with weight loss.2 Researchers have shown that choosing more whole-grains foods and those that are high in fibre help to control weight gain. In a study of women over a 12-year period of time, those who ate more whole-grain, high-fibre foods and fewer refined-grain products gained the least amount of weight.3

Behaviour in the Environment
The source of foods and where they are eaten are also important factors that affect weight. In a study of women in Australia, those who maintained a healthier weight were less likely to order in foods into their homes.4 Interestingly, these healthier-weight women also spent less time sitting.

Other factors related to the home environment also have been shown to impact weight – in particular, television viewing. Studies reveal that the amount of time spent in front of a television screen contributes to weight gain.5 And, both television viewing and listening to a recorded story on tape while eating have been shown to increase meal size.6 The bottom line: Creating a healthy-weight environment includes choosing wholesome foods and focusing on the food during meals without any distractions.
