Many different factors may have led to you putting on weight at this stage of your life. Some of these may have been physiological changes, while others may have been psychological issues. Understanding why this weight gain has occurred allows you to put things in context and to understand what action needs to be taken. Now is the time to get excited about what you can achieve for yourself, your body, your weight and your health.

Weight gain predominantly occurs because we are consuming more calories than we are burning off through physical activity.
