As overweight and obesity have become more common, there have been some major changes in how we live. These changes have led to people either eating more or becoming less active, all of which has contributed to an increase in overweight and obesity. For example:
The overall cost of food has gone down.
More food is prepared away from home.
Energy-dense foods and drinks are more readily available.
Portion sizes have increased.
Marketing of energy-dense foods and drinks has increased.
The use of cars has increased.
The number of two-income families has increased.
The time spent in paid employment has increased.
The role of physical education in the school curriculum has reduced.
