Istanbul: A new international study suggests that people who face longer working hours are more likely to be obese, while reducing working time could help improve public health outcomes.
The research, presented at the European Congress on Obesity in Istanbul, analysed working patterns and obesity prevalence across 33 OECD countries between 1990 and 2022. It found that countries such as the United States, Mexico and Colombia, where annual working hours are relatively high, also recorded higher obesity rates. This was observed despite some northern European countries consuming more energy-dense and fatty diets on average.
Reduced working hours linked to lower obesity rates
According to the study, a 1 percent reduction in annual working hours was associated with a 0.16 percent decrease in obesity rates. Researchers suggested that limited time for physical activity and increased work-related stress could be key contributing factors.
Dr. Pradeepa Korale-Gedara of the University of Queensland, the study’s lead author, said higher stress levels can elevate cortisol, a hormone linked to fat storage. Korale-Gedara also noted that demanding work environments often leave little opportunity for physical exercise.
Experts point to ‘time poverty’ and lifestyle habits
While the study does not establish direct causation, researchers say income levels and broader socioeconomic factors may also influence obesity trends.
Dr. Rita Fontinha, a psychologist at the University of Reading, said obesity is closely tied to ‘time poverty,’ particularly among individuals working long hours or multiple jobs. Rita Fontinha explained that limited time and energy often push people towards processed or ready-to-eat foods instead of home-cooked meals.
Growing debate over four-day working week
The findings have renewed discussions around the four-day working week, with campaigners arguing it could improve public health. James Reeves of the 4 Day Week Foundation said reduced working hours could help address obesity by enabling healthier lifestyles.
James Reeves added that governments should seriously consider shorter working weeks as part of wider health and productivity reforms.
Policy stance remains cautious
Despite growing interest in flexible working models, governments remain cautious about mandating shorter working weeks.
A government spokesperson said there are no plans to introduce a compulsory four-day working week on full pay, but highlighted ongoing efforts to support flexible working arrangements through employment reforms.
