This book complements Doctor Roy Walford's books very nicely.
The basic idea is that, by designing a diet which is lower in calories, but adequate in vitamins, minerals, etc., you can live a lot longer.
Dr. Walfords books introduce the idea, explain the evidence for believing that it will work, and tell you how to get started on such a diet. His books tend to be a bit technical, though very well written. You should at least read "The Anti-Aging Plan" by Roy and Lisa Walford before jumping into "The Longevity Diet."
"The Longevity Diet" isn't just a rehash of Dr. Walford's work. The authors' discuss the human, nontechnical side of the plan. How do you change your eating habits? How do you deal with cravings for ice cream, or social situations where you are expected to feast with others?
One of the recommendations involves keeping a diary of what you eat, and what situations make you over-eat, so that you can plan strategies to overcome them. You also use the food diary to count your calories, and nutrition.
They cover a number of other topics, introducing some recent developments, such as the ORAC index of foods, which tells you which foods are the best anti-oxidants (Blueberries), and the idea of energy density, which has to do with eating foods which have few calories in a large volume of food.
Other topics include Exercise, Relaxation techniques, major Theories of Aging, and the balance between Omega-3 and Omega-6 fatty acids.
For those who don't know, here's a synopsis of the CR (Calorie Restriction) movement:
In the 1930's, some researchers at Cornell discovered, by accident, that if you feed mice less than the normal amount, they live A LOT longer.
Further research indicated that if you feed them a diet very low in calories, but with complete nutrition (vitamins, minerals, etc.), the mice can live EVEN LONGER. In the most extreme situations, they can almost double the life span of mice.
Later, scientist started looking for a way to make a pill (or something) which would allow people to live longer. The only known way of making something live longer was to restrict it's calories, so they began to study caloric restriction. The idea was to make a pill which has effects similar to calroic restriction. This accomplished nothing fast.
Along comes Roy Walford of UCLA. Walford thinks the life extending pill is a great idea, but he's pretty sure it isn't going to be developed in our lifetime. Having a keen sense of the obvious, Walford recommends that people start practicing caloric restriction themselves. It works on every other species for which it has been tried, and it has the same biological effects on human cholesterol, blood pressure, etc. as it has on other species. WHY NOT???
By all means buy this book! While you're at it, pick up "The Anti-Aging Plan." Also, grab a copy of the Walford's free software at [...] .
