      sedentariness.

AB  - The population statistics of most countries of the world are indicating that 
      industrialization and computerization have been associated with an increase in 
      sedentariness and more recently with a significant shift from healthy weight to 
      overweight. In general, this change in the overweight/obesity prevalence is 
      attributed by health professionals to suboptimal diet and physical activity 
      practices. However, recent data raised the possibility that excess weight gain 
      might also be the outcome of changes imposed by our '24-hour', hectic lifestyle. 
      Parallel to an increase in body weight, one has observed a reduction in sleep 
      time and an increase in knowledge-based work (KBW) that appear as a growing 
      necessity in a context of economic competitiveness and globalization. Sleep and 
      cognitive work both exert a trivial effect on energy expenditure and may thus be 
      considered as sedentary activities. However, their respective effect on energy 
      intake is opposite. Indeed, an increase in the practice of the most sedentary 
      activity, i.e. sleep, is associated with a hormonal profile facilitating appetite 
      control whereas KBW appears as a stimulus favoring a significant enhancing effect 
      on food intake. Television viewing is another example of sedentary activity that 
      has been shown to increase the intake of high-density foods. These observations 
      demonstrate that the modern way of living has favored a change in human 
      activities whose impact goes well beyond what has traditionally been attributed 
      to a lack of physical exercise. Therefore, we will need to reconsider the notion 
      of 'sedentariness' which includes several activities having opposing effects on 
      energy balance.
