The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

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.
