With social distancing measures that limit eating out during the COVID-19 pandemic, people have been eating more take away food, thus changing their overall eating habits. A new survey about the “Changing Eating Habits of Hongkongers during COVID-19” revealed that Hong Kong people lacked exercise and dietary imbalances were serious during the epidemic. Due to the dual factors, nearly half of the participants said they gained weight during the epidemic and ate more snacks during this period. More than 95% of the people said they ate 4 to 5 meals a day.
Obesity and high blood pressure are now common health problems in society. A health survey by the Hong Kong Department of Health showed that among people aged 15 to 84, about 50% are overweight or obese. About 59.2% suffer from hypertension, diabetes and/or high cholesterol, while men have more serious weight problems than women. Obesity would increase the risk factors of chronic diseases, including high blood pressure, high blood pressure, high cholesterol, diabetes, cancer, etc.
Body mass index (BMI) is one of the methods to measure the degree of overweight and obesity. It is calculated by dividing body weight (in kilograms) by the square of height (in meters), or use the BMI calculator via the District Health Centre. For Hong Kong adults, a normal BMI index of 18 to 23, above 25 is considered to be slightly overweight, and more than 30 is severely obese.
Another method for measuring human adults is “dual energy X-ray absorptiometry”, or DEXA for short. DEXA can accurately analyze various parts of the body in terms of fat, muscle and bone composition and proportion. Although the technology is commonly used for measuring bone density, it’s also an effective way to measure whether someone is borderline overweight to help with weight management. The test is short and radiation levels are low, so can be implemented regularly as a more reliable measurement than calculating BMI.
Maintaining an ideal weight is the key to maintaining long-term health, but some people view weight loss as a lifelong goal. There is a flood of weight management information in the market, some of which are misleading, which makes people misunderstand and have prejudices against weight problems. If you do not understand the principles of food nutrition and healthy eating, coupled with the wrong way to lose weight, it may be counterproductive.
The doctors at The Central Clinic recommended that we use the following 4 tips to establish a positive outlook and understand food nutrition to help cultivate the concept of continuous healthy weight management:
Some people blindly follow the trend, neglecting their own preferences and feelings in order to achieve the goal of reduction. Some even believe that they must suffer a painful process, yet they would regain the weight they’ve lost. In fact, the key points about weight management are about making persistent changes, and keeping manageable goals that can be sustained.
Only focusing on one health indicator would not reflect one’s overall health status. The definition of health includes both physiological and mental aspects, and weight is only one part of physical health. Keeping healthy living habits are more important than simply watching weight.
The more types of food, the more extensive the substitution of nutrients, even if you don’t understand food nutrition, it is easy to supplement nutrition. Focusing too much on a certain nutrient or calories does not equate to a healthy diet.
Studies show that the only way to maintain weight loss is to exercise regularly. Physical activity not only helps reduce calorie intake, but also reduces the risk of cardiovascular disease, diabetes and cancer.
In addition, The Central Clinic also provides weight management plans for people with BMI above 25. Including follow-up by doctors and professional nutritionists, liver cirrhosis and whole body muscle/minor distribution scans and genetic analysis to help you understand your innate response to food, exercise and vitamins.

News.gov.hk – Healthier lifestyles urged
Hong Kong Economic Times – 2020/10/21 Article
過重及肥胖在現今社會很普遍，香港衞生署人口健康調查顯示，年齡介乎15至84歲人士中，約五成屬超重或肥胖；患高血壓、糖尿病和高膽固醇血症其中一種或以上的比率為59.2%，男性體重問題比女性嚴重。肥胖會增加患上慢性疾病的風險因素，包括高血壓 、心臟病 、高膽固醇 、糖尿病和癌症等等。
體重指數（ＢＭＩ）是量度過重和肥胖程度的其中一種方法 ，計算方法是把體重(以公斤為單位)除以身高(以米為單位)的平方，或利用地區康健中心的體重指標計算器計算。對香港成年人來說，正常ＢＭＩ指 數達於１８至２３，２５以上即屬輕微肥胖，而３０以上則為嚴重肥胖。
另一個測量人體脂肪的方法是「雙能量X光吸收」 簡稱「DEXA」(Dual Energy X-ray Absorptiometry) 。DEXA能正確地分析身體各部位的脂肪、肌肉和骨骼成份和比例。雖然最常用於度量骨質密度，這科技也能夠有效地驗出是否患有隱性肥胖而控制體重。DEXA檢查時間短，而且輻射性低，可作定期檢查，比僅依靠BMI更為可靠。
