For the over-weight and the obese people, regular two-minute breaks of light or moderate intensity activity like walking between the prolonged periods of sitting can be really effective. By doing so their insulin and glucose level remains under control. Obesity means having too much body fat. It is not the same as being overweight, which means weighing too much. However, both mean that a person’s weight is higher than what is thought to be healthy for his or her height. Taking in more calories than you burn can lead to obesity because the body stores unused calories as fat. Obesity can be caused by eating more food than your body can use, drinking too much alcohol, not getting enough exercise. Sometimes, medical problems or treatments cause weight gain, including under active thyroid gland (hypothyroidism) and medicines such as birth control pills, antidepressants, and antipsychotic.
Our bodies have a complex system to help keep our weight at a healthy level. In some people, this system does not work normally. Other factors that affect weight include the way we eat when we are children can affect the way we eat as adults. The way we eat over many years becomes a habit. It affects what we eat, when we eat, and how much we eat. We are surrounded by things that make it easy to overeat and hard to stay active. Many people do not have time to plan and make healthy meals, more people today work desk jobs compared to more active jobs in the past and people with less free time have less time to exercise.
Obesity is a leading preventable cause of death worldwide, with increasing prevalence in adults and children, and authorities view it as one of the most serious public health problems of the 21st century. Obesity increases the likelihood of various diseases, particularly heart disease, type 2 diabetes, obstructive sleep apnea, certain types of cancer, and osteoarthritis. Sitting for long periods and sedentary behavior is also a risk factor for chronic diseases, including some cancers. Our bodies are not designed for prolonged sitting. Activity can be undertaken to break up sitting time and counteract the negative effects of sitting for long periods, including the frequency of breaks required to improve health outcomes. Improvements are seen even with light-intensity activity, which is the equivalent of strolling. It is not the amount of effort involved that has an effect, but just the act of standing, moving and reducing sitting time.
