In addition to diabetes86 other lifestyle changes to consider:
• Use Google search on simple vs complex carbs and avoid all simple carbs. Avoid foods made with white flour [breads, crackers], starchy foods like potatoes and white rice. When foods are quickly digested, the sugar from these foods are absorbed into the blood stream rapidily thus elevating blood sugar levels.
• Lose the body fat. Number 1 reason for t2 diabetes is obesity. Many have reversed their diabetes by shedding the extra poundage. Not saying you will but being at normal weight makes you feel good.
• Maintain normal blood pressure and Lipid panels [cholesterol, triglycerides, HDL and LDL]
• Exercise 30-60 minutes daily. Go walking. That's the least you can do.
• Buy a home glucose test meter. Test before eating and 2-3 hours later. The latter will tell you about what you just ate did to your blood sugar levels. Goal is to be within normal range of 60-99 mg/dl.
All the above helps to lower blood sugar. You may remain a diabetic if sugar levels have remained high for long periods and/or you inherited the diabetes genes. Good luck -
eat low carb and lots of exercise. If that does not keep your BG under 140 at all times then insulin (yes, insulin is a natural hormone)
