Beschreibung:
Obesity occurs when energy intake exceeds energy expenditure. Humans expend energy through purposeful exercise and through changes in posture and movement that are associated with the routines of daily life [called nonexercise activity thermogenesis (NEAT)]. To examine NEAT's role in obesity, we recruited 10 lean and 10 mildly obese sedentary volunteers and measured their body postures and movements every half-second for 10 days. Obese individuals were seated, on average, 2 hours longer per day than lean individuals. Posture allocation did not change when the obese individuals lost weight or when lean individuals gained weight, suggesting that it is biologically determined. If obese individuals adopted the NEAT-enhanced behaviors of their lean counterparts, they might expend an additional 350 calories (kcal) per day.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levine, James A -- Lanningham-Foster, Lorraine M -- McCrady, Shelly K -- Krizan, Alisa C -- Olson, Leslie R -- Kane, Paul H -- Jensen, Michael D -- Clark, Matthew M -- DK56650/DK/NIDDK NIH HHS/ -- DK63226/DK/NIDDK NIH HHS/ -- DK66270/DK/NIDDK NIH HHS/ -- M01 RR00585/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2005 Jan 28;307(5709):584-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Endocrine Research Unit, Mayo Clinic, Rochester, MN 55905, USA.
