I bought this book because, although I don't have heart disease, I do have a family history of heart disease on both sides of the family. Having read the book, I decided to follow the nutrition plan for a trial period of 3 months. I am six weeks into that trial period now and it hasn't been too hard to follow although I would admit I have deviated from it on 4 or 5 meals during the six weeks so I haven't followed it absolutely rigidly. I took my blood cholesterol today. My previous 10 readings were all between 4.4mmol/L(170mg/dL) and 6.9mmol/L (265mg/dL) but after six weeks on this plan I recorded my lowest ever reading of 2.5mmol/L (~95mg/dL) and my ratio of total cholesterol to HDL was 3.57 which is well within the healthy range.
On top of that, I have lost weight, lost body fat, and I feel great despite not doing as much exercise as I should be doing. If you want to get your blood cholesterol down without taking drugs to achieve it, this is a great way to do it. It requires some effort, but it's worth it.
