It seems like a large percentage of our population is trying to lose weight – and it seems to get harder and harder. In fact, a study in the Journal of Obesity Research & Clinical Practice compared diet and exercise data over 4 decades and discovered that adults in 2006 had a higher BMI than those of the same age, diet, and activity patterns as those in 1988. Basically, it seems that it is more challenging to maintain a healthy body weight today than a generation ago. This is most likely because weight management is more complicated than just caloric intake and expenditure and involves environmental factors. For example, sleep, medications, hormones, chemicals, and pesticides may also be impacting our weight. It is very important to examine your entire lifestyle to manage your weight, and not just what you eat and how much you exercise.
