I would agree with the recommendation for Gary Taubes above.
I would also recommend watching the following lecture on you tube by a sweedish doctor, its great.
I lost 4 stone Jan-May doing a low fat diet on Weight Watchers- essentially eating exactly what the NHS currently recommend- low fat, lots of wholemeal pasta and rice, lean protein etc. I was dieting to improve my health mainly, and ate in a way they recommend to be a paragon of eating for cardiovascular health.
Then I read Gary Taubes book and learnt what the scientific research ACTUALLY shows and I couldn't believe it.
In eating this way I would have increased all my risk factors for CVD.
In particular low fat diets in women lower the rate of good cholesterol in the body which is the biggest risk factor for heart disease in women, more so than triglycerides or bad cholesterol etc.
He quotes many peer reviewed studies showing that the that the 'healthy' way of eating I had adopted was making me look thinner, but was making my body more sick.
I am now on a low car/high fat diet so that I can lose weight without damaging my health.
IMO the NHS is still prescribing a diet invented in the 1970s to please big cereal producers and the nation has in effect, been fattened up like cattle ever since.
The studies in Taubes book clearly show, for example, that people on a low carb, high fat diet not only lose more weight than people eating the same number of calories on a low fat diet, but that their triglyceride levels and bad cholesterol levels fall more significantly than those on a low fat diet.
