The good news is your risk of developing type 2 diabetes may be lowered with lifestyle changes like diet, exercise, and weight loss. If you’ve tried and failed to make changes before, remember that persistence is key, and even small changes can have a powerful impact. According to a Diabetes Prevention Program study sponsored by the National Institutes of Health (NIH), people at a high risk for developing type 2 diabetes who lost just 5 to 7% of their weight with diet or exercise were able to prevent or delay onset of the condition.
Childhood obesity rates are rising, and so are the rates of type 2 diabetes in youth. More than 75% of children with type 2 diabetes have a close relative who has it, too. But it’s not always because family members are related; it can also be because they share certain habits that can increase their risk. Parents can help prevent or delay type 2 diabetes by developing a plan for the whole family:
Sit Less, Move More. Aim for some daily physical activity. Exercise is important to help prevent type 2 diabetes and has so many other benefits. It can help you keep lost weight off, and improve your heart health, and if you’re insulin resistant, it can help increase your body's response to insulin (exercise so you will have better blood glucose control. Plus, exercise promotes better sleep, and can even reduce the symptoms of depression, helping put you in a better mood. 
Over a period of years, you went from pre-diabetes, to diabetes, to taking one medication, then two then three and then finally large doses of insulin. Here’s the thing. If you are taking more and more medications to keep your blood sugars at the same level, your diabetes is getting worse! Even if your blood sugars get better, your diabetes is getting worse. This is unfortunately what happens to virtually every patient. The body is already overflowing with sugar.
Choose lean sources of protein. Lean sources of protein include: eggs, egg whites, chicken breast, turkey breast, lean beef, pork tenderloin, fish (e.g., cod, tilapia, orange roughy), beans, or tofu. Adding protein to your daily intake helps to control spikes in blood sugar and helps with fullness to prevent unnecessary snacking on poor choices later.
People who have hypertension may follow a similar dietary plan to those who have diabetes. However, people with hypertension should also reduce sodium and caffeine intake. Individuals with both diabetes and hypertension should look for foods with low sodium counts, avoid coffee or caffeinated beverages, and avoid foods high in saturated and trans fats.
Recently, evidence suggested a link between the intake of soft drinks with obesity and diabetes, resulting from large amounts of high fructose corn syrup used in the manufacturing of soft drinks, which raises blood glucose levels and BMI to the dangerous levels.38 It was also stated by Assy39 that diet soft drinks contain glycated chemicals that markedly augment insulin resistance. Food intake has been strongly linked with obesity, not only related to the volume of food but also in terms of the composition and quality of diet.40 High intake of red meat, sweets and fried foods, contribute to the increased the risk of insulin resistance and T2DM.41 In contrast, an inverse correlation was observed between intake of vegetables and T2DM. Consumption of fruits and vegetables may protect the development of T2DM, as they are rich in nutrients, fiber and antioxidants which are considered as protective barrier against the diseases.42 Recently, in Japanese women, a report revealed that elevated intake of white rice was associated with an increased risk of T2DM.43 This demands an urgent need for changing lifestyle among general population and further increase the awareness of healthy diet patterns in all groups.
