UK’s obesity challenge: Learning from Japan’s effective approach
In Japan, a unique festive tradition involving Colonel Sanders statues dressed as Santa Claus outside KFC branches marks the start of the Christmas season. This tradition, a result of a marketing strategy from the 1970s, has become a cultural phenomenon, with millions participating in the “KFC Special Christmas Dinner”. This period is significant for KFC Japan, contributing to a substantial portion of their annual sales.
This contrasts sharply with the UK, where traditional home-cooked Christmas dinners are preferred. However, the issue for the UK lies in the dietary habits adopted for the rest of the year. The British tendency towards unhealthy eating has led to an escalating obesity crisis, now costing the economy almost £100 billion annually and impacting productivity far more than previously estimated.
The report by the Tony Blair Institute indicates a worrying trend: two-thirds of the UK’s population are either overweight or have obesity, a figure that has risen by around 11% since 1993. The economic impact of obesity, including healthcare costs and reduced productivity, is projected to increase by an additional £10 billion in the next 15 years. Henry Dimbleby, the government’s former food advisor, highlights the dire consequences of this trend. He points out that by 2035, the costs of treating Type 2 diabetes alone could surpass the current expenditure on all cancer treatments within the NHS.
Comparatively, Japan stands out with one of the lowest obesity rates among developed nations, a mere 4%. This has not always been the case. In the 1960s, Japan was considered one of the least healthy countries in the G7, with a diet heavily reliant on cheap US food imports post-World War II. However, over the following decades, Japan underwent a dramatic cultural shift concerning food, resulting in the world’s highest life expectancy. This transformation demonstrates that obesity is an addressable issue, requiring a change in cultural attitudes towards food rather than reliance on medication.
In Japan, the “bukatsudō” programme plays a pivotal role in promoting physical activity among schoolchildren. This initiative, coupled with the provision of healthier school meals, has contributed to Japan’s low obesity rates among children. In contrast, recent NHS figures show concerning trends in the UK, with significant percentages of children categorised as having overweight or obesity from a young age.
The traditional Japanese diet, which includes fresh fish, small portions of meat, tofu, and vegetables, is inherently healthier than typical Western diets. Andrew Kojima, a celebrity chef, suggests that the UK could benefit from adopting Japanese dining philosophies such as eating until only 80% full and ensuring a variety of colours and types of food in meals.
In Japan, there is a lesser emphasis on snacking and takeaway food compared to the UK. The quality of institutional food in Japan is also notably healthier. Dimbleby recalls a stay in a Tokyo hospital, where meals included healthy options such as pickles, rice porridge, grilled fish, miso soup, and steamed vegetables. He argues that such changes are feasible in the UK without significantly increasing budgets.
Dimbleby’s charity, Chefs in Schools, aims to improve the quality of school meals across England and advocates for an inspection regime similar to Ofsted for school dinners. Another potential strategy is adapting Japan’s “metabo” law, which mandates waistline measurements for citizens aged 40 to 74, with counselling and incentives for those who do not meet the standards. This approach could be implemented in the UK through voluntary annual health checks in workplaces.
Despite the need for action, the UK government has shown reluctance to intervene effectively. The National Food Strategy’s recommendations have been largely overlooked, and proposed anti-obesity measures like junk food deal bans and advertising restrictions have been delayed. Campaigners are calling for the sugar tax on soft drinks to be extended, but there is little movement from the government.
The lack of government intervention and the influence of corporations promoting high-calorie foods mean the UK continues to struggle with an obesity crisis. As the report highlights, Britain urgently needs to adopt successful strategies like those in Japan to address both the public health and economic challenges posed by obesity.
