1 in 3 South Africans are obese

One in three South Africans is now obese, with experts warning that half
of all women could fall into this category within five years if urgent action is not taken. According
to the 2025 World Obesity Atlas, South Africa’s obesity rate is rising faster than in many
Western nations – with sugar addiction at the centre of the crisis.

Even a BMI of 25 places a person in the overweight category, and at 30, they are classified as
obese, explains Dr Tommie Smook, medical practitioner at Dr Smook & Partners and co-owner
of practice manager RXME.

September is Heart Awareness Month, and Dr Smook stresses that sugar’s impact extends far
beyond waistlines. “Sugar dramatically increases the risk of high blood pressure, heart disease,
type 2 diabetes, and even depression. This is no longer just about weight – it’s about survival
and quality of life.”

Around 63% of South Africans under 70 already die from non-communicable diseases like
diabetes and heart disease, with excess weight a key risk factor.

Sugar’s grip on the body
Sugar is everywhere. It hides in cereals, sauces, and even fruit juices labelled “100% natural.”
Research shows that South Africans now consume nearly three times more sugar than they did
50 years ago, with ultra-processed foods driving this sharp rise.

“We’re in a war with sugar, and sugar is winning. It hijacks the brain’s reward system, creating
cravings and withdrawal symptoms. A soda contains about seven teaspoons of sugar – enough
to keep the cycle going,” says Dr Smook.

Over time, excess sugar raises blood pressure, inflames blood vessels, and builds up visceral
fat around organs. This creates the perfect storm for heart attacks and strokes, already placing
immense strain on South Africa’s health system.

Breaking the cycle
According to Dr Smook, you don’t have to go cold turkey to make progress and win the war
against sugar. Thoughtful changes, done consistently, can reset this relationship, helping you
feel lighter and more energised.

 Rethink sauces: a spoon of chutney may contain more sugar than a biscuit. Use spice
rubs or lemon juice instead.
 Skip flavoured drinks: infuse sparkling water with fruit slices instead of reaching for juice
or soda.
 Check your cereal: many “healthy” mueslis are sugar bombs. Choose oats with nuts and
fresh fruit.
 Beware of “low fat”: often these products are sugar-loaded to improve flavour. Stick to
whole, unprocessed foods.
 Sweeten naturally: cinnamon, citrus zest, or vanilla essence can replace sugar in coffee
or baking.

“These swaps retrain your taste buds over time, and suddenly, sugary foods aren’t as appealing
as they were before.”

The role of medical support
For many, sugar’s addictive pull is difficult to break alone. That’s where GLP-1 therapies –
medications originally developed for diabetes – have become a global breakthrough.
These treatments mimic the body’s natural hormones that regulate appetite, blood sugar, and
digestion. By reducing cravings, slowing digestion, and helping people feel fuller for longer, they
support safe, steady weight loss.

But the benefits go far beyond the scale. The effects of the GLP-1s are to stabilise blood sugar
and insulin levels, lower blood pressure, reduce inflammation, and improve blood vessel health,
all crucial for protecting the heart. Patients often see improved cholesterol levels, better blood
sugar control, and reduced cardiovascular risk alongside weight loss.

At Dr Smook & Partners, managed by RXME, GLP-1 treatments are customised to each patient
and supervised by medical experts as part of a comprehensive programme. Nationwide access
ensures that South Africans everywhere can benefit, not just those in major cities.

“Within weeks, patients notice fewer cravings, improved appetite control, and steady weight
loss. Combined with lifestyle changes, this represents the future of preventative health,
protecting South Africans’ hearts while helping them feel good in their own skin again,” Dr
Smook concludes.
