Increaseing Physical Activity in Daily Life / 임상당뇨병

Evidence from several studies indicates that obesity and weight gain are associated with an increased risk of diabetes. Obesity occurs when energy intake exceeds energy expenditure over a protracted period of time. The energy expenditure associated with everyday activity is commonly referred to as Non Exercise Activity Thermogenesis (NEAT). Increasing NEAT, improving diet, and sustaining these lifestyle changes can reduce body weight. This paper provides evidence that NEAT is important in understanding the cause of weight gain and in developing effective treatments for weight control.

Is Non-exercise Activity Thermogenesis-a Target for Reversing Obesity? / 中国临床营养杂志

Non-exercise activity thermogenesis (NEAT) is the energy expenditure of all physical activities other than volitional sporting-like exercise. NEAT includes all the activities that render us vibrant, unique and independent beings such as working, playing, and dancing. Because people of the same weight have markedly variable activity levels, it is not surprising that NEAT varies substantially between people by 2000 kcal/day. Evidence suggests that low NEAT may occur in obesity but in a very specific fashion. Obese individuals appear to exhibit an innate tendency to be seated for 2.5 hours per day more than sedentary lean counterparts. If obese individuals were to adopt the lean 'NEAT-o-type', they could potentially expend an additional 350 kcal/day. Obesity was rare a century ago and the human genotype has not changed over that time. Thus, the obesity epidemic may reflect the emergence of a chair-enticing environment to which those with an innate tendency to sit, did so and became obese. To reverse obesity therefore, we need to develop individual strategies to promote standing & ambulating time by 2.5 hours per day but also re-engineer our work, school and home environments to render active living the option of choice.
