Prediabetes is not a disease. It is a warning.
It means your blood sugar is higher than normal, but you still have the power to change your future. The right food choices can bring your glucose levels back to normal and stop diabetes before it starts.
A proper prediabetes diet plan is not about starvation or extreme diets. It is about balance, consistency, and understanding how food affects your blood sugar.
Your body does not react to taste.
It reacts to how fast food turns into glucose.
When you eat the right foods, your cells use sugar properly. When you eat the wrong ones, sugar stays in your blood and slowly damages your health.

Food is your first medicine.
