Weight loss/management..my spiel (part 4)

Now that we established the benefits of weight loss/management, let's talk about what may cause obesity. There are many factors that contribute to weight gain. The first may be a sickness. Hypothyroidism, for example, may cause weight gain because decreased thyroid hormone level can mean decreased metabolism. The second may be food intake. The large portion size, poor food choices, and binge eating/mindless eating can all contribute to weight gain. The third may be lack of physical activity. Having a sedentary job, for example, can lead to weight gain. It is very important to realize that all of these factors may cause weight gain/lack of weight loss. If there is an underlying illness that causes weight gain, it is strongly recommended that the person seek a medical professional's advice. If there is no underlying illness, then the weight gain may be due to simple math error: calories consumed being larger than the calories expended.
