Energy balance

Replacing seated computer work with walking-and-working on a vertical workstation significantly increases energy expenditure (by ~119 kcal/h) in obese individuals, potentially leading to substantial annual weight loss if sustained.

If you have obesity and sit at a computer all day, try replacing 2-3 hours of sitting with walking on a treadmill desk. This simple change can burn an extra ~120 calories per hour. Over a year, this could theoretically lead to significant weight loss (20-30 kg) without changing your diet, provided you stay consistent. Start with a slow walking speed and adjust as needed.

ModerateSupportsMEDIUM confidence
The mean (SD) increase in energy expenditure for walking-and-working over sitting was 119 (25) kcal/h... if obese individuals were to replace time spent sitting at the computer with walking computer time by 2–3 h/day... a weight loss of 20–30 kg/year could occur.

Why this rating

Small sample size (n=15), short duration (acute measurement), and lack of long-term weight loss data; however, the physiological measurement (indirect calorimetry) is precise.
