INTRODUCTION This case presentation shows the impact of low-carb-high-fat (LCHF) diet on a glucose variability and metabolic control in an obese type 1 diabetic patient. PATIENT 41-year old female has had type 1 diabetes since the age of 13. She has been treated with an insulin pump since 2011. In addition, she is on metformin 2000 mg daily due to polycystic ovary syndrome. Her glycaemic control was poor in the last years. Her HbA1c levels were around 8.0 % and there was high glucose variability (Figure 1). The patient has also been struggling with increased body weight. In July 2018 she adopted the LCHF diet. RESULTS Since the LCHF diet adoption the patient’s glycaemic control has improved dramatically. In the next three months her HbA1c decreased to 6.2 % and glucose variability has reduced immensely (Figure 2). Total daily insulin dose has reduced from 42 to 24 units and average basal/bolus ratio changed from 45/55 to 85/15. In addition, her body weight has decreased from 94 to 82 kg and her blood pressure has decreased from 155/85 mmHg to 127/82 mmHg. Patient also reported improved quality of life and confidence. On the other hand, her lipid profile has detoriated, with her total cholesterol level rising from 4.3 to 6.6 mmol/L and her LDL cholesterol level rising from 2.4 to 4.7 mmol/L. CONCLUSION In conclusion, the LCHF diet can improve glycaemic control as well as reduce body weight in an obese type 1 diabetic patient. However, lipid control may get worse.
