Preventing Type 2 Diabetes
Lifestyle changes that can lower your risk.
點解呢個 事情
A prediabetes result isn’t a diagnosis, it’s a signal. Without any changes, people with prediabetes progress to type 2 diabetes at a rate of roughly 5–10% a year. But that trajectory isn’t fixed: structured lifestyle change has been shown to cut that risk substantially, often more effectively than medication alone.
The Core Prevention Steps
These are the same four pillars used in the CDC-backed National Diabetes Prevention Program, and reflected in most international prevention guidelines:
Lose a modest amount of weight
Losing just 5–7% of body weight (around 10–14 lb / 4.5–6.5 kg for a 200 lb / 90 kg person) is the single change most strongly linked to lower diabetes risk in prevention trials.

Get at least 150 minutes of activity a week
Moderate-intensity aerobic activity, like brisk walking, spread across the week improves insulin sensitivity independently of weight loss. In practice: a 30-minute walk 5 days a week meets the target.

Make healthier food choices
Reducing refined carbohydrates and portion sizes, while increasing fibre from vegetables, fruit, and whole grains, supports both weight loss and better blood sugar control.

Consider a structured programme
People enrolled in a recognised lifestyle change programme, with a trained coach and group support, tend to sustain their changes better than those making changes alone.

Know your numbers
Being age 45 or older, carrying excess weight, or having a family history of diabetes all raise your chances. Knowing where you stand helps you and your care team decide how closely to monitor things.
A Note for Asian Body Types
Standard BMI cut-offs were developed largely from Western population data, and tend to underestimate risk in Asian populations, who often develop diabetes at a lower BMI due to higher visceral fat for the same weight. The World Health Organization’s Western Pacific Region recommends lower action points for Asian adults: a BMI of 23 or above is considered overweight, and 25 or above is considered obese, compared with 25 and 30 in Western guidelines. This is worth discussing with your care team when interpreting your own screening results.
Community Resources (Hong Kong)
Around 1 in 10 people in Hong Kong has diabetes, so local support is well established:
Change4Health, Department of Health
The Department of Health’s thematic platform for diabetes and obesity prevention, including the local Action Plan on Weight Management and Asian-specific BMI guidance.
Risk Assessment and Management Programme (RAMP)
A multi-disciplinary Hospital Authority programme for patients with, or at risk of, diabetes, combining risk stratification with structured follow-up care in public primary care clinics.
District Health Centres & DHC Expresses
Available in all 18 districts, offering diabetes risk assessments and referrals to dietetic and lifestyle support services.
