The process of type 2 diabetes begins years or even decades before the diagnosis of diabetes, with insulin resistance. Insulin resistance is the beginning of the body not dealing well with sugar, which is the breakdown product of all carbohydrates. Insulin tells certain body cells to open up and store glucose as fat. When the cells stop responding your blood sugar rises, which triggers the release of more insulin in a vicious cycle. Insulin resistance is associated with abdominal obesity, high blood pressure, high triglycerides, and low HDL ("good cholesterol"). When these occur together, it is known as metabolic syndrome or pre-diabetes. It is a risk factor for heart disease and type 2 diabetes.
For this method, you will need to learn what foods have carbohydrate in them, what information to look for on a food label, and how to approximate a serving of carbohydrate when a food label is not available. Once you become familiar with these, you will be able to easily track your carbs to make sure you're not consuming too much. You may want to keep a log throughout the day.

In general, prediabetes is not associated with any specific symptoms. However, there may be indicators of problems in blood sugar metabolism that can be seen years before the development of overt diabetes. Health-care professionals in the field of endocrinology are now routinely looking at these indicators in patients who are high risk for developing diabetes.
