Adherence
Obesity prevalence in developed countries is strongly linked to secular declines in Lifestyle Physical Activity (LSPA/NEAT) due to environmental and technological factors, rather than solely a decrease in leisure-time physical activity (LTPA).
Recognize that modern environments are designed to minimize movement. To combat this, intentionally integrate more movement into daily tasks (LSPA), such as walking for errands, taking stairs, or standing while working, as these small accumulations significantly impact long-term energy balance.
Thus, it is likely that declines in LSPA (or NEAT) have contributed to the increased prevalence of obesity, but unfortunately it is difficult to quantify this contribution.
Why this rating
The paper cites epidemiological data and cohort studies but explicitly states that prospective data documenting the decline in LSPA is scarce and difficult to quantify.
