The husband and wife authors, Paul Jaminet and Shou-Ching Jaminet of the
“Perfect Health Diet” (2010) are two doctorate-level scientists, (Paul a physicist and Shou-Ching a vascular biologist), who believe that conventional dietary advice is largely mistaken. As is the case with most authors of diet books, they experimented with the diet in their own lives; found it successful for them; and then wrote a book sharing what they learned.

The primary premise of the book is that disease and ill health are caused by three inter-related factors: food toxins, malnourishment, and chronic infections by bacteria, viruses, fungi, and protozoa; and that all three factors must be addressed by diet.

The Perfect Health Diet is based on “nutrient-rich superfoods” like egg yolks, liver and other organ meats, bone and joint soups, brain and bone marrow, seafood, seaweed, green leafy vegetables, and fermented vegetables. It includes a number of other meats, fats, oils, and “safe starches” to provide sufficient protein and calories

The Perfect Health Diet is approx. 65% fat., 20% carbs and 15% protein by calories, and by weight is approx 65% plants and 35% animal foods. It is a low-carb diet, but not a low-plant diet. Most of the carb calories come from what they call “safe starches” while most of the plant material consists of low-calorie, low-carb vegetables, and a small amount of fruit.

The authors are opposed to “calorie-reduced” diets, and rely on the body and foods eaten to naturally regulate calories without conscious restriction. They believe that a “nutrient-dense” diet reduces appetite. They also recommend Intermittent fasting for weight-loss, such as a 23 hr fast from dinner to dinner; or confining food to an 8 hr window daily with 16 hr fasts between eating periods.

The Basic Keys to the diet are:

*The diet should consist of: by weight, about 2/3 plant foods, 1/3 animal foods. Based on a “standard” 2000 calorie diet, daily fat intake should be 65% of daily food intake, or 1300 calories. Daily carbohydrate intake should be 400 calories, primarily from starches (e.g., rice, potatoes, sweet potatoes, taro), fruits, and berries, as well as a variety of low-calorie vegetables. Daily protein intake should be about 300 calories.

* Do not eat toxic foods such as:

* Do not eat cereal grains — wheat, barley, oats, corn — or foods made from them — bread, pasta, breakfast cereals, oatmeal. The exception is white rice, which count as “safe starches.” Rice noodles, rice crackers, and the like are fine.

* Do not eat calorie-rich legumes. Peas and green beans are fine. Soy and peanuts should be absolutely excluded. Beans might be acceptable with suitable preparation, but it is recommended to avoid them.

* Do not eat foods with added sugar or high-fructose corn syrup. Do not drink anything that contains sugar: healthy drinks are water, tea, and coffee.

* Polyunsaturated fats should be a small fraction of the diet (4% of total calories). To achieve this, do not eat seed oils such as soybean oil, corn oil, safflower oil, sunflower oil, canola oil, or the like. The best cooking oils are coconut oil, clarified butter, and beef tallow; palm oil, lard, olive oil, and avocado oil are next best. Nut butters are another possible source of fats.

* Eat nourishing foods such as: liver, egg yolks, seaweeds, shellfish, vegetable and bone broths. Make sauces from an acid (lemon juice, vinegar), an oil, and herbs. Get sufficient salt.

Overall, the Perfect Health Diet is an good introduction to the world of traditional Paleo eating. It is well referenced and well reasoned. The content ranges from practical to technical. Some of the more technical sections might be intimidating to someone who just wants to be told what they should eat. However, readers with an interest in nutrition or another science will probably find the book interesting.

The Jaminets provide an excellent discussion of the interconversion of different macronutrients which should certainly shake almost anyone out of a fat-phobia, once they realize how any excess carbs eaten are just turned into fat anyway.

Three concepts that are developed throughout the book are:

1. The concept of “Economics of Nutrition”, which is a discussion on food toxicity. With nutrition, the greatest benefit comes from the first amount eaten of any nutrient; each additional amount provides less benefit until eventually the benefit equals zero. Beyond the “plateau range”, a nutrient can become toxic, with increasing amounts becoming more and more toxic.

The authors evaluate the “marginal benefit curve” for carbohydrates, protein, and fats with numerous references to scientific literature.

2. How food is transformed by the body. In other words, what goes in the mouth is not the same as what it becomes in the body. Similarly, different foods produce different by-products after the digestion process. Some foods they address are wheat (and all grains), soy (and all legumes), sugar, and polyunsaturated fats (especially Omega 6s).

3.  Mammalian dietary strategies (omnivores, herbivores, carnivores) that have evolved over time, how humans are similar and where humans differ in dietary needs.

In conclusion, the Perfect Health Diet is similar to the Paleo Diet but with several important differences. The protein intake is lower and certain “safe starches” are a major part of the diet. This makes the macronutrient ratio comparable to that of Pacific islanders. This book provides a lot of information on micronutrients, however, guidance on how to implement the diet on a practical basis is probably insufficient for the majority of readers.

I found the book interesting, enjoyed reading it, and think it is a valuable reference book for a high-fat, low-carb, minimum protein …” way-of-eating”, “diet”, or “lifestyle”.
Am I going to personally experiment with this specific diet? I would probably do so BEFORE Hell froze over, but certainly not until AFTER I've exhausted the possibilities of a multitude of other diets that I find more compatible with my own food taste preferences.

                              
Which is better or most effective, cutting Carbs, or cutting Calories?

Everything I’ve seen and experienced personally, leads me to believe that calories matter even when one chooses to eat low-carb. There’s a possibility that one can eat a few more calories by reducing carbs, but … for most people … the amount of extra calories doesn't appear to be a very large number.

 It seems like there are an endless number of specific diets and rules for weight loss. One of the most popular of these rules is that cutting carbohydrates (carbs) is the best way to lose weight.

The Atkins diet, first popular in the 1970s.is the most famous low-carb diet. This diet recommends limiting foods high in carbs, such as bread, pasta, rice, and starchy vegetables such as corn and potatoes. Carbs are replaced with foods containing a higher percentage of proteins and fats (meat, poultry, fish, eggs and cheese) and other low-carb foods (mostly vegetables).

What does the evidence show us about whether low-carb diets really are better for weight loss and weight-maintenance than other diets?

Conventional wisdom says that a “calorie is a calorie” and it doesn't matter what types of food the calories come from, and therefore, all reduced-energy (calorie) diets should lead to equivalent weight loss.

However, some studies have reported that low-carb diets, in the short-term, lead to greater weight loss than other types of diets. What are some possible explanations for these results?

1. Changes in body composition

Energy is stored in the body as protein, fat, and glycogen, which is a form of carbohydrate. If there is an imbalance between how many of these nutrients are ingested (through the food that is eaten) and how many are used by the body for every day functions, body composition will change.

In turn, this will affect body weight because of the different impact that the relative amounts of stored protein, fat and carbohydrates have on body weight.

However, the vast majority of studies in which they’ve measured calorie intake very accurately (that is, they’ve locked people in a room and measured exactly what they’ve eaten for several days), show absolutely no difference in weight loss based on the composition of the diet. High-protein diets and high-carb diets resulted in the same weight loss.

2.  Changes in metabolic rate

The body’s metabolic rate (the amount of energy expended by the body in a given time) is dependent on the composition of the diet. Consumption of protein, for example, is known to result in a larger increase in energy expenditure for several hours after a meal compared with the consumption of fat or carbs.

But the overall effect of diet composition on total energy expenditure is relatively small. As a result, the assumption that a “calorie is a calorie” is probably a reasonable estimation as far as energy expenditure is concerned.

3.  Changes in hunger levels and satiety

Some diets can lead to reduced hunger, improved satiety (feeling full), and can be easier to stick to than others. There is an enormous amount of research on this.

The problem is that it’s extremely difficult to accurately measure what people are eating over extended time periods. In general, people rarely stick to their diets for more than just a few weeks, making it almost impossible to adequately compare the effects of different diets.

And so, is cutting carbs the best way to lose weight?  Maybe.

However, all diets with similar calorie content appear to have a similar effect on weight loss in the long-term. This is probably because the body adapts rapidly to changes in relative protein, fat and carbohydrate intake levels.

The truth is that losing weight and keeping it off in the long-term is difficult. It requires permanent changes to the number of calories you eat each day. My own maintenance struggle has involved experimenting with many different diets, or ways of eating.

  I believe the best diet for a person, is whatever diet that person is able to live with comfortably long-term. My own maintenance involves a continual process of looking for a way of eating that satisfies that criteria for me, personally.  As a part of that process, I’ve made Dieting into a rather enjoyable Hobby for myself, which is why this website is named DietHobby.

A strange and all too common phenomenon is the way a person, who is has never been very far beyond the borderline of the obesity range, loses around 20 to 30 lbs and suddenly becomes an expert on dieting and obesity.

These people take their personal experience with minor weight loss.. (which of course, might be MAJOR to them personally)… and decide that whatever worked for them ought to work for everyone, and that clearly the solution to the weight issue is easy, because “hey, if they can do it, so can anyone”.

This is like someone who has just finished their first piano lesson telling others about how to become a concert pianist.  It’s like asking someone without cancer how they prevented cancer in their own body, and then using those lessons to treat cancer patients.

I say to such a person:

"Congratulations on your weight loss. I'm sure it's significant to you. But you do not have the same issues that a person with 100 or 200 pounds to lose frequently has."

It’s almost amusing how everyone feels they have an “expert” opinion to share with someone who is trying to lose weight. Even people who have never had a weight problem tend to assume that they are doing something that fat people aren't doing, and therefore they also know the solution to obesity.

There are many naturally slim people (some of them who are even doctors or nutritionists) who truly think obese people are just ignorant, greedy, and lazy. After all, they, themselves, have slim bodies which stay slim by "occasionally taking walks and not eating entire gallons of ice cream in one sitting."  Especially, those who have mediocre processed food diets, and are borderline sedentary, are very quick to assume that obese people must have VERY bad habits.

Anyone who truly believes that people who continually struggle with weight issues are simply missing the information, personal desire, and sense of personal responsibility it takes to succeed, is showing that they don't have a grasp on what it really is, to struggle with a great deal of excess weight, nor an understanding of obesity’s difficult issues. The "eat-less-move-more formula," for a morbidly obese person, is frequently far more complex than even the majority of medical professionals make it out to be.

The habits as outlined in the National Weight Registry Control research – which appear necessary for the majority who succeed at weight-loss maintenance, …. such as daily weighing, calorie counting, lots of exercise etc….. are the same behaviors that are castigated by those medical professionals who involve themselves with treatment of “Eating Disorders”. And yet there is an immense amount of proof that if a reduced obese person stops self-monitoring and making immediate corrections, the weight comes back on without fail.

Many people find it easy to lose a bit of weight, but the body fights back, so very few are able to do what it takes to keep it off.  Invariably when I read "inspiring" weight loss stories in the popular media, 99% of those profiled haven't even made it to the 5-year maintenance mark. When .. and if ... they get there, I’d like to hear about it. Also, please tell me what society you can live in where normal sized people don't feel compelled to shame fat people. I'd like to move there.

Sometimes doing what it take for weight-loss maintenance feels like a dreary way to live. My own position is: “Being Fat is Hard. Losing Weight is Hard. Maintaining Weight is Hard. Choose Your Hard.”

Weight loss is difficult and often complex, no matter how determined you are.
As a reduced obese person who is now maintaining a large weight-loss, I am well aware that obese people sometimes make excuses and wallow in self-pity instead of doing things that they “know” will be effective in decreasing weight. Many people spend decades looking for the magic of an easy way, while in basic denial of the simple truth that eating less calories than you burn will …in most cases…. lead to weight loss.  Truthfully, it is very hard to believe how few calories an obese person actually burns, because for many, the Scientific Theory that 3500 calories equals 1 fat lb just doesn't always hold true for everyone at every weight.

More precisely, it's not that we fat people need to hear this from others - after all, what fat person hasn't already heard it a thousand times?. Rather, it's something that many of us need to take to heart once and for all, instead of continually ignoring/denying the Reality of the difficulty of the consistent, ongoing, lifetime effort it is really going to take.

Eat less calories than we burn.  However, how do we individually DO that?
And then, … how do we do it consistently, FOREVER?
Obesity can't be treated with a one-size-fits-all solution. We are not cookie cutter people and what works for one person won't necessarily work for another. How great it would be if everyone could truely take to heart the message within the video below.

Although almost every weight-loss expert seems to have something to sell,
...... despite the marketing hype ,...... there are kernals of truth in many of the basic things they say.
 

"Science has failed us in the weight loss department.
It literally gets an “F.”

The culture has failed us as well. Far too many people have intense moral judgments towards anyone with excess pounds, which contributes to the hidden epidemic of social disconnection, apathy, and plain old sadness.

Let’s face it: when it comes to the subject of weight gain and weight loss, we’re clueless.  And from that place of cluelessness we tend to flail around, we try our hand at the most inane weight loss strategies, we diet for decades, we consume diet foods ...that are, if you care to closely study the scientific literature ... toxic."
