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.

The objective of the study was to ascertain the association of various foods with changes in waist circumference. The study included 48,631 men and women from five countries who were followed for 5.5 years.

Regarding butter and margarine, the study found:
(a) For each 100 calorie increase in butter consumption there was a .01 centimetre per year decrease in waist circumference.
(b) For each 100 calorie increase in margarine consumption there was a .03 centimetre per year increase in waist circumference.

The data from the study reveals higher butter consumption is associated with thinner waistlines whereas higher margarine consumption is associated with fatter waistlines.
