Energy balance

For obese diabetic patients, a moderate caloric deficit (reducing intake by 500 kcal/day to achieve ~0.5 kg/week loss) is the recommended standard, whereas extremely low-calorie diets (VLCD) are not recommended due to unverified long-term effectiveness and increased risks of hypoglycemia and ketoacidosis.

Aim to reduce your daily calorie intake by 500 calories from what you currently eat. This should result in losing about 0.5 to 1 kilogram per week. Do not use extremely low-calorie diets (like under 800 kcal/day) without strict medical supervision, as they can cause dangerous blood sugar drops or ketoacidosis in diabetic patients. Adjust your target based on your activity level and body size.
