This study examined the effects of a high-fat, low-carbohydrate, diet on 22 patients with type I diabetes who were failing to control fluctuations in their blood sugar levels in higher carbohydrate diets. The diet was limited to around 70-90 grams a day of carbohydrate and excluded potatoes, rice, pasta, bread and cereals. The diet consisted of 20% carbohydrate, 30% protein and 50% fat.
After 12 months on the high-fat, low-carbohydrate, diet, the study found:
(a) Hypoglycaemic episodes (where the blood glucose levels drop to abnormally low dangerous values) decreased from 2.9 episodes per week to 0.5 episodes per week.
(b) Meal insulin requirements decreased from 21.1 Iu per day to 12.4 Iu per day.
(c) Unhealthy high triglyceride levels decreased by 33%.
This study shows that a high-fat, low-carbohydrate, diet is a feasible long-term treatment of type 1 diabetes and leads to improved blood glucose control.
