Followers have been showering monks – who are deeply respected in the kingdom – with foods loaded with sugar, fat and oil, prodding along a brewing health crisis.
Every morning Buddhist monk Pipit Sarakitwinon takes walks around his temple and does hundreds of arm exercises, part of a new regimen aimed at shedding pounds as a health overhaul for members of the clergy gathers pace in Thailand.
Followers have been showering monks – who are deeply respected in the kingdom – with foods loaded with sugar, fat and oil, contributing to a brewing health crisis.
"Before I dieted I could barely walk 100 metres without getting tired", Pipit, 63, told AFP during a medical check-up at a hospital for monks in Bangkok, adding that he used to weigh 180 kilogrammes.
'Monk Health Charter'
With cases of diabetes, hypertension and knee problems skyrocketing, Thai health and religious officials last December published a "Monk Health Charter", instructing members of the clergy to watch what they eat.
Thais seeking to earn merit and honour their ancestors often provide food to monks on their daily rounds but they can be generous to a fault.
Heavy curries, sugary sweets, sodas and salty snacks are among the array of sumptuous – and unhealthy – alms.
"If they eat our food and are satisfied, we feel comfort that that food will be transferred to our loved ones," said Prachaksvich Lebnak, deputy secretary general at the National Health Security Office.
"Some people even give monks cigarettes," he added, in a symbolic offering to ancestors who were heavy smokers.
'Can't reject' food
Thais boast some of the highest rates of obesity in Asia, according to the Asian Development Bank.
Members of the clergy are among the worst-hit – a 2016 survey of monks by the Faculty of Allied Health Sciences at Chulalongkorn University in Bangkok found rates of obesity soaring as high as 48 percent, with 42 percent suffering from high blood pressure.
Buddhist precepts forbid monks from eating after noon and Buddha himself was said to have told his followers to refrain from consuming meals later in the day.
But certain juices – referred to as pana in religious scripture – are allowed after midday, making them perfect delivery vehicles for sugar.
Pre-packed alms that include processed foods are also easily available at Thai stores, exacerbating the problem.
Although the new guidelines call on monks to look after their health so they can be " ready to deliver Buddha's teachings", refusing devotees' offerings is a delicate subject.
"According to Lord Buddha's teaching, whatever they offer, we have to accept. We can't deny, we can't reject," said Phra Rajvoramuni, the assistant abbot at Sungvej temple in Bangkok who helped author the new charter.
Rajvoramuni hopes instead that health education – including training clergy to run basic medical check-ups – will bring about change.
"The monks also should do something, like exercise... like walking meditation, cleaning the temple in the morning, sweeping the grounds," he said.
