Amazon.com Review
The Diamonds explain that body functions have a daily cycle: noon to 8 p.m.-- appropriation (eating and digestion); 8 p.m. to 4 a.m.--assimilation (absorption and use); 4 a.m. to noon--elimination (of body wastes and food debris). Fit for Life aims to return you to a lifestyle based on your natural body cycles. That means 70 percent of your diet should be "high-water-content foods"--fruits and vegetables--which facilitate all body functions. Consume nothing but fruit or fruit juice until noon, then eat salad and vegetables with every meal for the rest of the day.
Two-thirds of the book is explanation and discussion; one-third is menu plans and recipes. You won't be hungry, your food choices will be healthy, and you'll lose weight without dieting. --Joan Price

Marilyn Diamond was the first health pioneer to bring mainstream America the message that diet and health are connected, breaking new ground as the originator, underwriter and co-author of Fit for Life, the fourth bestselling book of the 1980’s and the first million seller for Warner Books.
Her tireless role as model and spokesperson in countless television appearances prior to the Internet drove Fit for Life to the Top 25 Bestselling Books in History List in 1986 and earned Marilyn the love and respect of a vast health-seeking, anti-aging and longevity international audience.
Marilyn has authored or co-authored six other books since Fit for Life, and she returns today to break new ground again with Young for Life: The No-Diet, No-Sweat Plan to Look and Feel 10 Years Younger (Rodale Books, April 2013) This coming year, Marilyn will highlight the PBS Young for Life Pledge Drive from August 2013 to September 2014. She holds a Phi Beta Kappa Magna Cum Laude BA from New York University.

- Reviewed in the United States on November 9, 2011Principles herein can't be more contrary to today's conventional meal but which, if adhered to, brings great rewards for those who suffer frequent indigestion.
Spoken from personal experience as well as hvg witnessed a business associate get healthy over an 18mth project.
The book theorises that the body undergoes 3 major phases of food processing through a 24hour day. Phase 1 - Eating & Digestion (12noon-8pm); Phase 2 - Absorption (8pm-4am); and Phase 3 - Excretion (4am-12noon).
The author categorizes food into 3 categories: 1) carbohydate, 2) protein and 3) vegetables and advocates that food be consumed in compatible category combinations that would result in optimal digestion. For example, it maintains that proteins and carbohydrates should never be consumed together as the enzymes secreted to digest the respective classes tended to cancel out each other's digestive powers, neutralising the acidity/ alkalinity of the enzymes. As a result of which slows digestion, lengthening the time poorly digested food spends in the stomach. Nutrient absorption is impaired, and food would end up sitting in the digestive tract longer than it should, exposing it to a higher incidence of putrefication whenever it encounters sugary substances (desserts after a meal is a bad idea). This contributes to rapid putrefication - imagine foul odious sludge & gas sitting in one's intestines, going no where and the resulting emissions!. Rather - the aim is to maximise digestion and absorption and waste material expelled in the shortest possible time.
RATHER than carbs as the common food staple, theory advocates treating vegetables as the staple (common food) to be taken together with proteins and then separately in a different meal with carbs. Importantly, Diamond advocates that fruits be consumed on an empty stomach, best for breakfast in any amount till satisfied up till noon. The rationale here is to avoid diverting fresh energy from the previous night's good sleep to digesting a heavy meal, preferring rather to channel the available energy to the day's morning pursuits. Simple carbs from fruits are in absorbable form and provides the required energy for the cleansing (waste mgmt) cycle in the morning - when excretion best take place. A logical deduction from here then is for carbs & vegetables to be eaten at lunch - hence allowing the energy it generates to be used through the afternoon (rather than stored overnight). Proteins & vegetables otoh, is best consumed at night to resource muscle repair & recovery after the day's pursuits.
This overall eating formula aims to promote digestive health as well as aid effective weight loss - and it works! Caution though that what works for one may not work or be redundant for another. Hence listen to your own body. It's a gem for me.

- Reviewed in the United States on December 24, 2023I bought this book in the late 80's as a weight-loss book, and it does definitely work that way if you follow its directions. The most lasting and valuable difference it made in my life however was to make me really enjoy vegetables and salads for the first time in my life. Growing up in the 1960's, vegetables and salads were sad dutiful little side dishes. But if you follow the meal plans in Fit for Life, you will be, well, full of vegetables. Your body will then begin to crave them, crave that feeling of well-being that comes from eating a lot of them.
But the reason this works for so many people is, the vegetables as prepared in this book taste incredibly good. Marilyn Diamond was already a skilled and enthusiastic cook before meeting Harry, and she brought her culinary talents to the challenge of making vegetables yummy. She succeeded magnificently. My only problem with the recipes is the same one I have with most recipes: I can't prepare them nearly as quickly as the time estimates provided for doing so. It's a lot of cooking time and I don't even like to cook. I'm willing to do it though because I'm convinced I feel better eating this way and it does taste so good.
When 15 years after discovering this book I decided to give up meat, it was completely painless because I already knew how delicious and satisfying vegetarian cooking can be. Most although not all of the recipes in the book are indeed vegetarian, although some aren't so you can kind of phase in.
Strongly recommended, for healtys and thoroughly enjoyable eating!

Fit For Live
Le livre est très instructif et très clair, facile et un peu amusant à lire.
Nous avons tout de suite commencé le style de vie recommendé par l'auteur, comme celui corespondait déjà beaucoup avec le notre!
L'auteur te fait voir common beaucoup de ses récommandations font sens.
Le livre est écrit c'est trente ans et est encore toujours actuel.
Pour ceux qui cherchent à maigrir il dit -arrète tous les régimes qui ne tiennent pas après qu'on les à finit; maigrir, c'est une mode de vie, a life style!!
