Such a shame that this is what society needs, but it does. Hopefully it catches on.
The energy expenditure of using a "walk-and-work" desk for office workers with obesity.

Objective: For many people, most of the working day is spent sitting in front of a computer screen. Approaches for obesity treatment and prevention are being sought to increase workplace physical activity because low levels of physical activity are associated with obesity. Our hypothesis was that a vertical workstation that allows an obese individual to work while walking would be associated with significant and substantial increases in energy expenditure over seated work.
Methods: The vertical workstation is a workstation that allows an office worker to use a standard personal computer while walking on a treadmill at a self-selected velocity. 15 sedentary individuals with obesity (14 women, one man; 43 (7.5) years, 86 (9.6) kg; body mass index 32 (2.6) kg/m2) underwent measurements of energy expenditure at rest, seated working in an office chair, standing and while walking at a self-selected speed using the vertical workstation. Body composition was measured using dual x ray absorptiometry.
Results: The mean (SD) energy expenditure while seated at work in an office chair was 72 (10) kcal/h, whereas the energy expenditure while walking and working at a self-selected velocity of 1.1 (0.4) mph was 191 (29) kcal/h. The mean (SD) increase in energy expenditure for walking-and-working over sitting was 119 (25) kcal/h.
Conclusions: If sitting computer-time were replaced by walking-and-working, energy expenditure could increase by 100 kcal/h. Thus, if obese individuals were to replace time spent sitting at the computer with walking computer time by 2-3 h/day, and if other components of energy balance were constant, a weight loss of 20-30 kg/year could occur.
I stand corrected....... by myself......Walking on an electric treadmill while performing VDT office work

The physiological and psychological health problems associated with sedentary office work are well documented, but their solution has proved elusive. In this study a specially designed office permitted the comparison of conventional word processing (sedentary condition) to word processing performed while walking on an electric treadmill at 1.4 to 2.8 km/hr (active condition). Five subjects after several days of practice produced two test trials each consisting of six 20-minute intervals of word processing. For the sedentary condition the subjects were seated, during all six intervals. For the active condition, treadmill-walking and seated intervals were alternated. Variables measured included word processing performance score, stress and arousal indices, and body complaint count. The first of these was tested with a repeated ANOVA and Newman-Keuls post hoc, and the latter three with correlated t-tests. No significant differences were found between the two conditions for performance or body complaints. Stress was significantly lower (p < .05), and arousal was higher but not quite significant (P < .07) for the active condition. We conclude that treadmill walking and routine word processing can be performed concurrently without a decrement in work performance, and that certain physiological and psychological benefits may result.
^^ I've heard bad things about this. Can't remember where I read it, but it increases all sorts of other office issues. RSI (or whatever the Occupational Health and Safety people call it now) motion sickness, eye fatigue, can't really remember. I'll see if I can find it.
I just remember that it was better to get up from the desk every 20mins and doing something. They suggested getting a drink or printing something or walking over to someone elses desk instead of phoning them, etc.
