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.

A substantial decline in the percentage of fat consumption during the last two decades has corresponded with a massive increase in obesity

This post includes a summary of a paper published in Obesity Reviews 2002 May;3(2):59-68 and a recipe for chicken fajitas.

Does decreasing fat intake lead to a reduction in weight? In an analysis of short-term trials, it was estimated that a decrease in 10% of energy from fat would reduce weight by 16g a day, which would correspond to a 9-kg weight loss by 18 months.

However, compensatory mechanisms appear to operate because in trials lasting one year or longer, fat consumption within the range of 18-40% of energy has consistently had little, if any, effect on body fatness.

Moreover, within the United States, a substantial decline in the percentage of energy from fat during the last two decades has corresponded with a massive increase in obesity, and similar trends are occurring in other affluent countries.

Diets high in fat do not account for the high prevalence of excess body fat in Western countries; reductions in the percentage of energy from fat will have no important benefits and could further exacerbate this problem.

Willett concludes: The emphasis on total fat reduction has been a serious distraction in efforts to control obesity and improve health in general.
