What you need to remember
- The study that changed everything — The Diabetes Prevention Program (DPP), a landmark clinical trial involving 3,234 pre-diabetic individuals, demonstrated that:
- 7 concrete actions — Lose 5-7% of your weight**: for an 80 kg person, this represents 4-6 kg.
- Non-modifiable risk factors — Family history of type 2 diabetes
Type 2 diabetes is a global epidemic: 537 million people affected according to the International Diabetes Federation. But it is one of the most preventable chronic diseases.
The study that changed everything
The Diabetes Prevention Program (DPP), a landmark clinical trial involving 3,234 pre-diabetic individuals, demonstrated that:
- The "lifestyle program" reduced the risk by 58%
- Metformin reduced it by 31%
- For those over 60, the reduction reached 71% with lifestyle changes
7 concrete actions
- Lose 5-7% of your weight: for an 80 kg person, this represents 4-6 kg. No need to reach "ideal" weight.
- 150 minutes of physical activity per week: brisk walking, cycling, swimming.
- Reduce refined carbohydrates: white bread, white pasta, white rice, added sugars.
- Increase fiber: minimum 30 g/day (legumes, whole grains, vegetables).
- Limit sugary drinks: one soda a day increases the risk by 26%.
- Sleep 7-8 hours: chronic lack of sleep impairs glucose tolerance.
- Manage stress: chronic cortisol increases blood sugar.
Non-modifiable risk factors
- Family history of type 2 diabetes
- Ethnic origin (increased risk in certain populations)
- History of gestational diabetes
- Age > 45 years
Prediabetes is reversible. It's a window of opportunity to act before the disease sets in.
