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.

Decrease of testosterone during a low-fat high-fibre diet

This post includes a synopsis of a stusy published in the Journal of Steroid Biochemistry Volume 18, Issue 3, March 1983, Pages 369-370 and a recipe for alfresco beef Kkebabs.

The concentrations of total and free testosterone were studied in 30 healthy, middle-aged men during a dietary intervention program. When men were transferred from their customary diet to an experimental diet, which contained less fat with a higher polyunsaturated/saturated ratio (P/S-ratio) and more fibre, there was a significant decrease in serum total testosterone concentrations. Furthermore, unbound testosterone also decreased.

High fat diets give protection from metabolic syndrome

The study evaluated the effects of fat and fiber consumption on sex hormones in men.

Men were assigned into 2 groups eating (a) Low fat, high fibre diet (b) High fat, low fibre diet.

The men on the high fat, low fibre diet had higher total and sex-hormone-binding-globulin (SHBG)-bound testosterone levels by 13% and 15% respectively.

Higher testosterone and SHBG levels are associated with a reduced risk of metabolic syndrome.
