Obesity: Is your waistline killing you?

Did you know that 31% of men and 68% of women in South Africa are obese? Being overweight or obese not only affects your self-esteem, it also leads to heart disease and potentially an early death. This is a big problem, not only in adults but also in children. 13% of South African children are obese.  As a parent, you can reduce the risk of obesity in your children by making sure they eat healthy at school.

According to Stats SA, 62.2% women and 25.1% men in the Western Cape are overweight or obese. 

Julia Goedecke, a senior specialist for the Medical Research Council of South Africa said that many do not understand the health consequences of being overweight. "People don’t understand it; they see it as more of an aesthetic problem than a health problem".

She said that culture influences perceptions around obesity. "In some cultures obesity is associated with health and prosperity".

What is obesity? 

Obesity is defined as being overweight or as having too much body fat – especially in your waist area. A high-risk waistline is 80cm or higher for women and 94cm or higher for men. Once your waistline goes above these levels, it increases your risk of high blood pressure, diabetes and cardiovascular disease. 

The healthy body mass index (BMI) range is 18.5 – 24.9, while overweight people score 25 to 29.9 and obese people score 30 or higher.

How to calculate your BMI.

Calculate BMI by dividing weight in kilograms by height in centimetres TWICE.

For example: 90 kg / 180 cm = 50 and then you divide the answer by your height  50 / 180cm = 27.8

Why obesity matters

Being overweight can increase your risk of having the following health problems:

• Heart disease - extra weight puts strain on the heart.
• High cholesterol levels, which can increase the danger of heart attack and stroke.
• Diabetes.
• Certain cancers.
• Gallstones.
• Sleep apnoea.
• High blood pressure.
• Arthritis.
• Psychological problems (obese people may feel very insecure about their weight).

What causes obesity?

There are several factors that cause obesity:

• Poor eating habits - such as takeaways and animal fats.
• Lack of exercise.
• Family history - if parents are overweight, children often follow the pattern.
• Pregnancy - the more pregnancies a woman has, the more likely she is to put on weight.
• Negative emotions, which can cause some people to eat as a comfort mechanism.

How do I fight obesity? 

The following lifestyle changes are recommended for losing unwanted weight:

• Exercise regularly.
• Increase your intake of fibre, which makes your stomach feel fuller for longer.
• Eat at least five portions of vegetables and fruit daily.
• Use healthier cooking methods such as steaming, boiling and grilling.
• Choose low fat foods.
• Eat smaller portions.
• Limit your salt intake, because salt makes your body retain water.
• Drink between six to eight glasses of water a day.
