Overview

What is Fit For Life?

Harvey Diamond, along with Marilyn Diamond, crafted the Fit for Life diet plan, centered on the premise that a carefully chosen combination of foods can foster optimal health. The regimen advocates for a morning diet exclusively comprising fruits and emphasizes the consumption of predominantly raw fruits, vegetables, and foods with high water content throughout the day. An essential tenet of the diet involves abstaining from certain food categories altogether, particularly advising against the simultaneous consumption of animal protein and complex carbohydrates.

Furthermore, the Fit for Life diet places a strong emphasis on incorporating whole grains into one’s meals, gradually phasing out refined grains and processed foods. By prioritizing the consumption of nutrient-dense, minimally processed foods, the diet aims to support overall well-being through a strategic approach to nutrition.

  • Advances in Nutrition – Unfortunately, this idea of eliminating refined grains may not be based on solid science. According to some research, “the recommendation to reduce refined grain intake based on results from studies linking a Western dietary pattern to numerous adverse health outcomes is contrary to a substantial body of published scientific evidence. Future research needs to better define refined grain intake to distinguish between staple grain foods and indulgent grain foods, and to better design randomized controlled trials to resolve discrepancies between results from observational studies and such trials with regard to determining the benefits of whole grains compared with refined grains.”
  • The American Journal of Clinical Nutrition – In one clinical study, replacing whole grains for refined grains evoked some positive changes on gut microbiota, which could be a benefit to consider.
  • The American Journal of Clinical Nutrition – Another study published in this journal showed that whole grains actually affected resting metabolic rate and “may favorably influence energy balance and may help explain epidemiologic associations between whole-grain consumption and reduced body weight and adiposity.”

Food and exercise are the two critical aspects of healthy living. You are what you eat, so when you decide to get Fit for Life, you should research the many diet plans currently on the market.

We have compiled a complete Fit for Life analysis to understand the science behind the program and the food combining chart and meal plan.

Take your time to read this article before you follow this famous but controversial diet plan.

How Did Fit For Life Start?

The origins of the Fit for Life diet plan trace back to the Nature Cure movement and find their roots in Orthopathy or Natural Hygiene, asserting that fasting, dietary choices, and lifestyle adjustments suffice for disease prevention and treatment, as claimed by the plan’s proponents. Harvey Diamond and his wife, Marilyn Diamond, pioneers of the Fit for Life concept and co-authors of the eponymous book, delved into the principles of food combining, drawing inspiration from the theories of Herbert M. Shelton.

Central to their philosophy was the categorization of food into two distinct types: ‘dead food,’ characterized by high refinement and perceived as harmful to the body, and ‘living food,’ encompassing raw vegetables and fruits, believed to rejuvenate and cleanse the body. This foundational principle laid the groundwork for the development of the Fit for Life program. The diet gained widespread attention in the mid-1980s when the Diamonds published their bestselling book, “Fit for Life,” as it garnered recognition from The New York Times. Harvey Diamond further promoted the Fit for Life diet through numerous television talk show appearances.

In the sequel, “Fit for Life II” (1989), the Diamonds extended their dietary guidance, cautioning against the consumption of artificial food additives like hydrogenated vegetable oil. During that era, the food industry touted hydrogenated vegetable oil as a healthy alternative to saturated fat, prompting the Diamonds to emphasize the potential risks associated with such additives.

Fit For Life diet plan

Diet Plan

The Basic Ideas For Harvey Diamond Fit For Life Diet Plan

This diet is all about the good and bad combinations of food. ‘Dead’ food is not a part of the diet.

Diamond believed that the wrong combination of food could cause the food to ‘ferment’ in the stomach. Here are the main points of the diet plan.

Dairy products can cause allergies and should rarely be eaten, if at all. They are not considered to contribute valuable nutrition.

Water is not an option during meals because it would dilute digestive juices.

Fruits should be eaten raw and fresh. And you must eat them without other food.

It is ill-advised to combine proteins with carbohydrates during meals.

The dietary principle involves consuming predominantly ‘live’ food with high water content.
When animal protein is eaten,  avoid complex carbohydrates.

Fit for Life recipes Harvey Diamond offers to let us see what this diet offers each day.

Breakfast

Fit For Life Harvey Diamond – Breakfast

A typical breakfast in Fit for Life meal plan would consist of carbohydrates. They can be eaten alone or with vegetables.

Carbohydrates should not be consumed with animal protein foods such as milk, butter, or cream. They should also not be eaten with fruits. There should be a profusion of whole grain (bread, muffin, bagel) in the servings. Fit for life’s food combination chart gives us an idea of the foods that should and should not be combined.

Lunch

Fit For Life Recipes – Lunch

Lunch can be enjoyed in two different ways: combining protein with vegetables or combining carbohydrates with vegetables. Combining proteins and carbohydrates in one meal is strongly discouraged.

For example, you could have carbohydrates in whole wheat bread with bean sprouts, grated carrots, add some lettuce, or steamed brown rice with stir-fried vegetables.

Protein foods will have vegetable salads with chickpeas (garbanzo beans) or red kidney beans and sunflower seeds. You might relish a steaming cup of lentil soup with a variety of vegetables and a drizzle of light oil-based dressings instead of milk or cream.

Fit For Life dinners

Dinner

Fit For Life Food Combining Dinner

While breakfast and lunch are carbohydrate-loaded meals, the Fit for Life diet recommends high-protein dinners. Diamond advises against animal proteins (except for organic eggs and fresh fish).

Some of the Fit for Life recipes for dinner include vegetarian chili with beans and lentils, or assorted vegetable and legume curry or stew.

Other stable dishes are stir-fried tofu with Asian vegetables, raw salad vegetables, and steamed asparagus.

Dairy Products

Dairy Products In Fit For Life

Drinking milk or eating other dairy products such as butter, cheese, yogurt, pudding, cottage cheese, etc. is prohibited by the Fit for Life diet program.

The reason is that the human digestive tract is not designed to digest dairy products properly. This could lead to many problems, such as allergies.

To alleviate this problem, Diamond offers a supplement. The USDA asserts that dairy products are the primary source of calcium and recommend adults to have up to 3 cups of dairy products per day.

Dairy also supplies protein, according to Nutrients.

Fit For Life fruit

Fruits

Fruits In Fit For Life Meal Plan

Fruits must be eaten alone or consumed as juice but never with other food. The diet also suggests that fruits be consumed early in the morning, not in the afternoon.

This is because fruits have digestive enzymes with cleansing properties. It is very beneficial to eat them and activate the digestive system, according to Advances in Nutrition.

Book

Fit For Life Book

The Fit for Life book by Harvey and Marilyn Diamond explains the diet and lifestyle. This diet became popular in the 1980s and was a New York Times bestseller, selling millions of copies.

Through the book, Diamonds urged people to reject chemical additives and hydrogenated vegetable oil (popularized at that time as an alternative to butter). They advocated for veganism to increase energy levels.

Claims

Fit For Life Claims

Fit for Life Harvey and Marilyn Diamond claims that following their diet plan Fit for Life, will cause weight loss and prevent obsessions with counting calories and exercising vigorously.

A reasonable exercise schedule with the Fit for Life meal plan can help you get Fit for Life. Diamond claimed that mixing different foods can cause fermentation, which would kill valuable nutrients and enzymes.

In the 2000s, the Diamonds launched FFL’s Weight Management Program, which uses genetic predisposition, metabolic typing, and “analyzation” to create a Personalized FFL.

This Fit For Life meal plan can be used for each individual throughout his or her life. In this version, there was no more talk of ‘dead’ and ‘living,’ but the emphasis was on enzyme-rich or enzyme-deficient foods.

They promptly began selling enzyme supplements called as nutritional supplements.

Fit For Life whole grains

Ingredients

Fit For Life Ingredients

The Harvey Diamond Fit for Life diet recipes is mostly made of unprocessed whole foods.

The strategies of combining certain groups of food are not proven to improve health and have no firm scientific basis. The diet chiefly consists of:

  • Whole-grain foods
  • Legumes
  • Beans
  • Raw fruits and vegetables
  • Fresh fish
  • Organic eggs
  • Vegetable oils and seasoning
  • Food with high water content

Research published in the Annual Review of Food Science and Technology and the Journal of Chiropractic Medicine found that consuming whole grains could reduce the risk of chronic health problems, like obesity.

More research published in Frontiers in Psychology noted that consuming raw fruits and vegetables may lead to better mental health. Additionally, one study published in Clinical Diabetes found that legumes could reduce the risk of high blood pressure.

Does It Work?

Does Fit For Life Work?

The Fit for Life diet, centered on lifestyle modifications and dietary choices, has witnessed anecdotal success stories, with individuals attributing weight loss to its principles. Notably, public figures like Tony Robbins have endorsed Fit for Life and veganism, emphasizing increased energy levels in their pursuits. However, the correlation between the reported weight loss and the authors’ insights, as opposed to simple calorie restrictions, remains uncertain.

While the Fit for Life approach has garnered praise from some, skepticism persists within the nutrition and health community regarding its efficacy in delivering the promised weight loss. Regarded by some as a longstanding yet enduring fad, the diet lacks robust scientific support for many of its proclaimed principles and benefits. Despite the mention of “clinical trials” on the Fit for Life website, several assertions lack citations to scholarly research, and some claims have been directly contradicted by scientific studies.

Harvey Diamond’s credentials have faced scrutiny, questioning his competence in nutrition due to the non-accredited nature of his doctoral degree from the American College of Life Science. Moreover, criticisms extend to Fit for Life’s personalized diet program, particularly the “Clinical Manual,” which incorporates alternative medicine claims about the body’s workings, some of which may lack scientific accuracy.

Benefits & Results

Fit For Life Benefits And Results

Though widely known as a diet for weight loss without causing adverse effects, Fit for Life is much more than just a diet program.

It is a healthier way of living. Unlike the many crash diets that cause you to lose weight drastically but bounce back to your original weight in a trice, Fit for Life by Harvey Diamond does not cause this yo-yo effect.

After the initial days of perpetual hunger pangs, you will get used to (and even look forward to) short and frequent snack breaks. Healthy eating and proper hydration result in weight loss.

Details On Fit For Life And Weight Loss

The fundamental principle of this diet plan states that just by eating more amounts of the right type of food, you can alter your life, get into shape, and live happily.

The plan entails adhering to your body’s natural cycles of digestion, assimilation, and excretion and eliminating highly refined grains from your diet.

Fit For Life 24

This is a premier all-week and all-day fitness center that offers free nutrition programs with a low membership fee of barely $10 per month.

The center offers the most diverse fixed and free weights and has the widest variety of equipment, including flat benches, squat racks, and many more.

Fit for Life 24 is the go-to fitness center for those who yearn to be Fit for Life.

Directions

How To Diet With Fit For Life

The first step is to divide your day into three phases or time pockets. When you adhere to this natural cycle of life, your body works best, and everything else falls into place. Noon to 8 pm is the time for eating food and its digestion.

8 pm to 4 am is the time for assimilation when your body absorbs and uses. 4 am to noon to eliminate waste. Once you follow this pattern, you can get Fit for Life.

Fit For Life foods list

FFL Food List

The Good And The Bad FFL Food

FFL promotes eating fruit by itself earlier in the day when your stomach is empty. You must wait 30 minutes before you consume any other food.

Proteins should be eaten as a main course combined with a large helping of vegetables as a side dish. Starches can also be eaten as a main course with vegetables.

Oils, animal fats, and dairy products cause indigestion, weight gain, and are likely to ferment in the stomach. Seed oils and nut butter are preferred.

Non-starchy fruits and vegetables with high water content and fiber such as zucchini, squash, cucumber, collards, lettuce, cabbage, parsley, okra, beet greens, kale, asparagus, tomatoes, sweet peppers, and broccoli are recommended.

Garlic, leeks, shallots, radishes, and onions are considered irritants and should be used sparingly.

Food Combining Chart

Fit For Life Food Combining Chart

The idea behind combining varieties of food is to complement nutritive values. Diamond strongly believed in this.

It is the basis for the Fit for Life food combining chart. Although the concept itself was around for decades, the Fit for Life book by Harvey Diamond served to popularize it.

This chart is a perfect guide for people who wish to learn which food combinations will work for them. Health Authority has a food combination chart.

The Fit for Life diet plan works around the food combining chart and natural body cycle.

Consequently, there is a restriction on what can be eaten and at what time of the day. The diet eschews the consumption of dairy products, animal protein, and processed food.

The diet also advocates certain combinations of food.

Diamond believed that when food was properly combined to promote good digestion, it will result in weight loss and also body energization.

Side Effects

Side Effects Of Fit For Life Diet Plan

One of the most apparent side effects is the overwhelming pangs of hunger.

The diet requires you to start the day with a bowl of serving of fruits. With a breakfast of a bowl of fruits, you will be counting minutes for the mid-morning snack, a whole wheat bagel, or another bowl of fruit.

There are specific kinds of food which can be in combination, so the choice is quite limited. As a result, this diet can leave you feeling perpetually hungry, tired, and continually looking forward to the next meal.

Fit For Life warnings

Warnings

Fit For Life Diet Plan Warnings

The first complaint of skeptics is the lack of sound scientific backing for some of the diet’s rules. Eating healthy whole grains and fresh produce is a welcoming start, but there are many claims which lack proof.

This is probably because the authors lack expertise in this field. They don’t have the educational qualification, or training, or personal experience to validate their claims in the book.

This amounts to dishonesty, and there was a lawsuit in this regard. There is no sound scientific proof for many of their claims.

Lawsuits

Any Fit For Life Lawsuits?

As previously stated, there are speculations about the authenticity of the claims made by Fit for Life’s Harvey Diamond and Marilyn Diamond due to their lack of qualifications.

The doctorate he obtained from a University of questionable credentials was proved to be bogus.

Two decades after their book shot them to celebrity status, and a divorce later, Harvey Diamond and his son were in court again with his other son, Beau Diamond, who faced Ponzi scheme charges, reports the Sarasota Herald-Tribune.

There is no trace of documented lawsuits against the controversial diet plan.

Scientific Reviews

Reception To Fit For Life Diet Plan By Scientists

Health experts and nutritionists have scant regard for the book by Diamonds and have dismissed it as sheer quackery. Not only are Harvey Diamond’s credentials widely disputed, but many of the book’s claims have also been questioned by the scientific community.

The ideas propounded in the FFL diet have heavy leanings to alternative medicine, especially on how our bodies work. Some of the ideas are not acceptable by conventional medicine, and others totally contradict scientific research, as the book Complementary and Alternative Medicine in the United States reports.

Fit For Life alternatives

Alternatives

Fit For Life Alternatives

The diet plan is similar to many plant-based, low calorie, high-protein diets, and discourages the consumption of processed food.

This was a revolutionary idea at that time, but there are several current meal plans and diets where people are more aware and conscious of their health and food habits.

The following diets could be regarded as alternatives to the FFL diet plan:

The Seven-Day Hay Diet

This is based on combining specific foods and avoiding foods which can increase acidity levels in your system and hinder the digestion process.

Three- Day Fruit And Vegetable Diet

This is a detox diet that is prescribed to cleansing your system. Vegetables and fruits are rich in fiber, antioxidants, vitamins, and minerals and can help reduce the risk of obesity and other health problems. This is followed only for three days. Then a regular diet is resumed.

Two-Week Vegan Meal Plan

This is for those considering turning vegan or for die-hard vegans who want to try new delicacies.

What Users Are Saying

What Users Are Saying

“I read this book some years ago. About halfway through I realized that what I was reading was utter nonsense. The authors talk, for example, about the importance of eating “live atoms” vs. “dead atoms”. Atoms are just atoms — they’re not “alive” or “dead”. There are also many fallacious and irrelevant “appeal to authority” arguments, such as telling readers that Henry Ford favored their ideas, and therefore they must be correct. Much of their description of basic digestive biology (acidic vs. alkaline digestive juices) is just plain wrong. My conclusion: the authors are a couple of quacks who have no idea what they’re talking about. Stay far away from this book.”

“I liked that the book try to show a different approach to eating your favorite foods, while also showing you a healthier way of eating them and why.”

“I bought Fit for Life years ago (in 1989/1990) after a coworker recommended it. I was only 22 years old but my health was seriously going down hill. I had bad eczema on my legs, bad anxiety, a lot of weight gain, and a nauseous stomach. After switching over to Fit for Life my eczema cleared up miraculously, I achieved my ideal weight, and my anxiety went way down. I ended up with some new stomach issues (like gas and just feeling not right) and went to a great GI doctor who spent an hour with me trying to figure that out. He concluded that these new symptoms were because of the huge increase in fruits and vegetables. He said to keep it up! He told me not to stop, that it would go away as my body got used to the fiber. He was right! I stayed on Fit for Life for the majority of six years (despite having cheated quite a bit, which my husband called “fit for death”) and my weight stayed at a nice healthy number. People were intrigued and would ask me what I was doing. When I had my daughter in 1996 and the doctor (filling in for my ob/gyn) was sewing me up (c-section) and my stomach laid flat the doctor said, “Oh, you must have been thin to start with.” When I left the hospital the nurse at the station said I shouldn’t look that good after having a baby. And I fit right back into my old clothes when I got home. Unfortunately, I didn’t stay with the program and my weight fluctuated (mostly up) over the last 27 years or so. But now that I am 56 I am going to try it again. I am rereading the book on audio and loving it! And I’ve started doing it once again. I’m already noticing improvements and am very excited to get back on track. Sadly, there are so many people reviewing this that say almost the same thing as me; had great success, quit, and now are ready to try again after health issues.”

Bottom Line

The Bottom Line On Fit For Life

What’s the real deal with the Fit for Life diet? The program has numerous glowing reviews from people who have successfully lost weight. However, the science indicates that these individuals lost weight due to calorie restrictions rather than valuable insights. According to authorities in health and nutrition, this is little more than a fad diet, which is why we have reservations about giving it our support. It’s also expensive, and the price and food list are only visible once you sign up, which feels shady.

If you are ready to lose weight, we suggest sticking with a diet plan created with careful study and is strongly backed by the medical community. You may want to try a weight-loss program that uses a unique set of methods that are supported by reliable scientific testing and strong customer support.

Among the best programs we’ve seen this year is called Noom. The program combines the latest weight-loss and tracking technology with human coaching, and personalized meal plans to create a customized weight-loss plan. During our research, we didn’t find any negative online reviews. What we did find was glowing commentary from happy customers who successfully lost excess weight.

The makers of Noom are so excited about their product that they are now offering a free trial offer, which many dieters have begun taking advantage of.

    It has been 10 good and healthful years with Fit For Life. I, together with my family just followed the principles outlined.

    I have been following Fit For Life since my early 20s (I’m now in my late 40s). My weight has only increased minimally over this time (5kgs), due to normal body changes with age. I have always cheated a little by having milk in my coffee and a small tub of plain yoghurt (with a sprinkling of cinnamon and a tablespoon of nuts or seeds) for mid afternoon snack. I firmly believe that not combining protein and starch in a meal is the trick – on the occasions when I have done this, then I always feel tired and “heavy” after that cheat meal. I do stick to only fruit until noon, and drink water and herbal or green teas during that time too (water alone gets boring). It works for me, but every body is different, so find the eating lifestyle that suits you and run with it (so to speak) – good luck!

  • Thank You Marilyn
    Maria A Rooney (Verified Purchase)

    I read this book when it first came out and it is probably,for me,the best book on health I have ever read. Eating only fruit in the morning cured my stomach ulcer. I never connected what I ate and the consequences of constipation from all the bacteria built up. Fast forward at least 20 years and now the medical professionals are getting the connections but they use drugs. Before I read the book, I was going to medical doctors and they gave me medicine that perpetuated the ulcer by constipating me. It was a miracle in my life that this book came out when it did. Also the body clock works also. It is true. I have followed Marilyn a little bit and she has diverted some from the all vegetarian way of eating and kind if went to the other extreme of eating red meat. All is good but I will never forget their first book and the life change it brought me. I will thank them now.

      Probably because at the age 13 your body weight is supposed to fluctuate like crazy. You gain weight and then get taller. Girly, go eat a cheeseburger.

      Hi Jaz
      I first did this diet 20 years ago…It was miraculous!!! However, one day I began having unbearable headaches after breakfast. I stopped the diet and inevitably I gained back the lost weight and my body began to produce massive cholesterol. I contacted the book’s author by email. He gave me no valid answer. After all these years, I’ve done it again. This time I have a protein with raw and cooked vegetables for lunch and dinner. It works!!!

      I am thinking about going on Fit for life diet. I don’t have to lose any weight but am looking for help with digesting my food and would like help with my mental clarity. Has anyone have benefited from following this diet in these areas? Thank you for you responding to answering my request to my question.

        Yes, it’s main goal is to make suggestion easier on your body. I have IBS & heartburn, but when I follow the diet, those things go away.

  • Don't want to give up coffee
    Val (Verified Purchase)

    Has anyone had luck adhering to the fruit in the morning but also having coffee? I lost weight in the 80’s by following it strictly, but can’t muster the motivation to give up my coffee. Other than that I love the diet. Any thoughts?

      I wonder that too. I also wonder if I am losing weight due to the principles since I dry. It all day or if it is calorie reduction. Still fell good and do believe.

  • I lost about 70 lbs over 6 months
    Renee (Verified Purchase)

    I first read Fit for Life in 1990 after putting on 80 lbs with my pregnancy and breast feeding. I started having extreme heart burn no matter what I ate. My chiropractor boyfriend gave me this book to read. I started immediately and lost about 70 lbs over 6 months. I immediately had more energy and needed less sleep. My mood improved and I was always happy and energetic. I even started running. Over, the years, I did not follow the diet so well but when things got out of control I started back on it. It always immediately works and I feel great. I am 46 and very healthy. No medications or concerns. I do mostly eat organic and not a lot of meat. Medical evidence or not, this has worked for me for 18 years.

  • Can have water and fruit in morning?
    Mike McTamney (Verified Purchase)

    Can you drink water during the morning hours when you are eating only fruit? Not sure if this working – sorry for multiple questions that are the same.

      I’ve had this book since the early 90’s, two years ago I started seriously and have lost 15kilos. I;ve never felt better in my life, so much energy–I even started jogging and I’m 59.But when you have your fruit in the morning I only have a cup of warm water with it, I have tried coffee or green tea but my stomach feels better with just the water,2 hours later I’ll have a green tea, I’m afraid cofee is now a thing of the past for me now, after being a good coffee drinker for years. I love the way I feel and I sleep so much better too.

  • Dr. Siegel is better than it.
    Judy Stark (Verified Purchase)

    I tried the Fit For Life Cookie Diet because it was cheaper than Dr. Siegel’s Cookie Diet. I loved the latter, but the former was cheaper and thought I’d give it a try. The Dr. Siegel’s cookies are wonderful. And you really felt like you were eating a cookie. And they worked just as stated. On the other hand, the Fit for Life cookies were pretty bad. I felt like I was eating flavored mud. I guess if you took really small bites and just swallowed instead of chewing, it might be okay. But, what’s the fun in that? I’m going back to Dr. Siegel’s Cookie Diet.

  • I not only lost weight, but I got healthy
    Lynne Dufour (Verified Purchase)

    I bought, read, and followed “Fit For Life”, back in the 80’s. It is funny to read, good and healthy to follow, and is true. I not only lost weight, but I got healthy. My mother followed it and her acid reflux went away. Both of us has energy and felt great. I am going to get back to the basics once again. I have to find my book.

      Fit For Life is the way to love your life!! My doctor was amazed at the complete turnaround of my health! Cholesterol, Blood Pressure is now normal. Sleep Apnea is now gone. 60 pounds of extra weight is also gone. Doctor told me to just keep doing what I’m doing. I wish I could convince all my friends to follow the recommendations in this book. It has given me my life back!!

        Good for you! I purchased the book in the 80’s and it worked for me. I never felt hungry. At breakfast I would have watermelon and if I felt hungry later I had some bowl of cantalope. I would even juice them. i would get busy with my day. Lunch and dinner would be meat/salad. Example fish and salad and veg, Tuna bowl, with lettuce tomatoes, shredded cabbage, etc., I stayed away from the starchy veggies. Remember you could eat as many veggies as you want. If I wanted whole grains that day, I would stir fry veggies with whole grain rice and have a salad. I took an aerobic class in morning and once I went back to work I took a exercise class in the evening. It was great, I was able to lose weight and keep it off. I am 64 years old and the young people at my job can’t believe it. I always have lots of energy and can say, I have been blessed.
