The caloric requirement for people with moderate physical activity is approximately 35 kcal/kg/day, but there is a significant variation from person-to-person and day-to-day activity. Individualized instruction should consider the patient’s caloric needs, ethnicity, habits, constraints, and prescribed insulin regiment. The diet for patients with diabetes should aim to achieve an ideal HbA1c, blood pressure, and lipid profile. Attention should be paid to balance the energy intake and expenditure to avoid excess weight gain. Patients on fixed-dose insulin regimens need to have a consistent day-to-day carbohydrate intake. Mastery of either an exchange system or carbohydrate-counting allows for flexibility in meal planning, and helps avoid postprandial hypo- or hyperglycemia. Review of dietary principles is a cost-effective way to help the patient achieve treatment targets.

A low carbohydrate diet would reduce the average blood glucose levels in patients with diabetes by limiting the postprandial glucose, in addition to any improvement in insulin sensitivity from weight loss. The American Diabetes Association recommends either a low-fat or low-carbohydrate diet (<150 g/day) for weight loss in overweight/obesity patients with diabetes. A ketogenic diet in obese diabetic patients for 24 weeks also resulted in lower HbA1c, weight, and triglycerides, and higher HDL cholesterol.

Diabetic diet DO’s
