On our English pages, you often see the word "relationships". This is just sanitized language. On our English pages, "relationships" refers to what couples, when not sleeping, do in bed. Or, if so inclined, on the kitchen table.

English is a rather hypocritical language. Many words for natural bodily functions and processes have dirty connotations, and polite speakers like us have to go to considerable length to communicate meanings without naming them. But we nevertheless hope you get the point.

Tongkatali.org's Eat chocolate and lose weight

By Serge Kreutz

If I would have to select just one food that I would be allowed to put into my mouth until the end of my days, it would choose chocolate… and I would not need 10 seconds of thinking before coming up with that decision.

For many, many years, I have been a consumer of chocolate in large amounts, long before the Serge Kreutz diet idea struck me.

The taste of no other food has such a great effect on my brain.

And after the Serge Kreutz diet idea did occur to me, I noticed quickly that no other food is as suited for kreutzing as is chocolate.

It fully liquefies in the mouth, and it is so easy to discard into a plastic bag. Very little slides into the esophagus, and even for strict kreutzing is is one of the most suited foods.

You can go through 100 or 150 gram of chocolate several times a day, and what makes it to your digestive system is probably just 1 or 2 grams each time.

On many people, chocolate has a great uplifting effect. Conventional science credits this effect to the theobromine and other chemical constituents of chocolate.

But conventional is less than half-true with this assessment.

The psychological effect of chocolate comes from the taste. And this is something you will soon discover if you get into kreutzing food.

Chocolate has a lot of calories. Who cares, haha! When kreutzing chocolate, you get practically none of them.

But if for whatever reason, kreutzing is not for you, here some paragraphs that nevertheless advise you to eat chocolate. They were written before I had the kreutzing idea.

My whole life, I have been concerned with dietary issues.

I had and have to. If I don’t do that, I suffer from debilitating migraine every second day.

I have also had a phase in my life when I was some 40 kilos overweight. I am only 10 kilo overweight now.(This was before I came up with the Serge Kreutz diet idea! I am 20 kilo down from the 10 kilo overweight.)

I could write a diet book. But as of now, it’s just a few websites with some articles.

(obsolete paragraphs omitted)

Which macro nutrient is the biggest burden for the digestive system.

Not fat.

The biggest burden is protein. All proteins contain nitrogen, and when proteins are used as fuel, many nitrogenous toxins are formed.

I am very, very prone to migraine headaches. And the surest way to provoke them is eating cheese. And it has been suggested that the tyramine in aged protein food such as cheese is the trigger.

But by eliminating cheese alone, I cannot get rid of my migraines. I know other trigger food. Eggs for example, fresh eggs, from hens gathering their food running around a farm.

Or from eating chicken at KFC.

I don’t get migraine from eating quality milk chocolate. I can eat nothing else but milk chocolate for three days, up to a kilo a day. No migraine, also no sub-migraine. (But I can’t guarantee this for every brand of dark chocolate.)

I have tried purely vegetarian diets, heavy on peanuts and broccoli, but I still get migraines.

I have finally found the common denominator of all food causing me migraines, and sub- migraine headaches, or just a subtle condition of not feeling fresh.

The common denominator is proteinoverload. The digestion of protein and amino acids anyway produces more toxic by-products than then digestion of any other macro nutrient, all because of the nitrogen they contain. And tyramine, the old culprit and gang leader of migraine triggers, is a nitrogen compound, too.

Of course, I, as everybody else need protein as a nutrient. But how much protein do I need? 30 to 40 gram a day, maybe. Anything more is detrimental to my well-being.

Mind you, anybody eating recognized quality food will have a hard time to not get beyond the 30 to 40 gram of protein per day.

And anybody of the hundreds of millions of people who suffer from migraines and lesser headaches, and who I suggest give protein-restriction a try, can happily go without animal protein and need not worry about not reaching the 30 to 40 grams a day.

Many vegetables, and even grains, are sufficient sources of protein, though one may want to avoid soy products (because they are estrogenic, and soy protein digestion results in particularly toxic by-products) as well as grains and legumes (both with many problematic proteins). Even then, there is no shortage of protein sources. The dry mass of broccoli is around 50 percent protein, and asparagus and spinach are good sources, too.

That much on proteins. How about carbs?

I don’t think they are as problematic as proteins. I, and millions of others, don’t suffer migraine attacks from eating carbs.

But while carbs may not be as heavy on the digestive system as proteins, they aren’t as light as fats either.

Carbs enter the blood stream as sugar, regardless of whether they were ingested as “healthy” greens or “unhealthy” refined sweets, or tasteless starch.

Carbs and fats are more related to each other then either of the two is to protein. The liver converts fat into glucose fairly easily without toxic by-products.

However, there is an easily definable problem with carbohydrates, which is feeling hunger. If carbs are eaten and digested, they result in elevated blood sugar levels. The body has to answer this with releasing insulin.

But this biological response seems to lack fine-tuning. For after the over-sugar phase, there will next be a phase of under-sugar resulting in feeling hungry, regardless of whether the meal supplied enough calories for pending activities or not .

And then they eat. And then they are overweight.

Most people wrongly believe that dietary fats make them fat. Because after having eaten a meal with a sufficient amount of fat people can feel satiated for hours.

But if they just foolishly replace all fats with carbs, they will inevitably be hungry after a short while. And because being hungry is by and large a disturbing feeling, most people just eat.

Now, I am not propagating of a low-carb diet. For curiosity, I have tried it. But while a meal of protein and fat may supply enough calories, it doesn’t satisfy my carving for food. I have to eat some carbs to be happy and fit.

Conventional wisdom, suggests that about half of one’s intake of food should be carbs.

Now what carbs?

Quality carbs. And they should have two, not just one quality. First they should be of good nutritional value, also supplying minerals and vitamins. Second, they should appeal to the taste buds.

Whether they are natural or processed isn’t the issue, really. It’s their biochemical composition that matters.

Grains are tasty, but the proteins that accompany the carbs are critical. The same is the case with many legumes.

On the other hand, while it’s reputation is terrible, refined sugar really is just pure carbs. And I would give it preference over that other simple carb, which is starch.

Taste-wise, sugar beats starch hands-down.

And therefore, it does so also in one nutritional department that is often not considered: the psychological effect of food.

Enter chocolate.

I consider chocolate the most psychologically nutritious food of all.

You can serve me a steak. I eat it.

Then I see a plate of chocolate. I desire it.

You think I am still hungry, so you serve me another steak. OK, I eat it.

But seeing the chocolate, I will still desire it.

This won’t go away with eating yet another steak. I may feel very, very full, but the desire for the chocolate I see will still be there. I really have to force myself not to eat it.

But try it the other way around. Let me eat the chocolate first.

If now I decide that I want to diet and therefore reduce my calorie intake, I can happily go without the steak(s).

I will desire some non-sweet food eventually, but if I do want to lose weight, I can easily eat just chocolate all day, nothing else.

Anyway, nutritionally chocolate fares quite well. Milk chocolate has about 7 gram of protein per 100 gram, and 59 gram of carbs and 29 gram of fat, with about 4 gram of fiber.

As a meal composition, that sounds fairly good to most people, at least as long they don’t know that this meal is just chocolate.

Sure, some necessary micro nutrients such as vitamin C are not supplied (easy to get anywhere, eat some fruit).

On the other hand, chocolate contains some other micro nutrients that otherwise are quite rare, such as phenolics.

So, go ahead, lose weight, eat chocolate. (Of course, kreutzing chocolate is superior to eating chocolate any way you look at it. And chocolate is an important component of the Serge Kreutz diet.)

Marijuana or tongkat ali for better relationships, part 1

By Serge Kreutz

Cannabis Opinion, 2019

There is a fundamental difference between marijuana and tongkat ali.

Regardless of how enthusiastic you are about marijuana, there is no doubt that it makes you feel drugged. You may call it high, or stoned, or bright. Fact is that your brain doesn't feel sober.

Some people like to feel drugged most of the day or all day. For them, marijuana is better than cocaine or meth, and better than alcohol or barbiturates. It's certainly better than heroin or other opiates.

I am not one of those.

Apart from the time I am engaged in relationships conduct, I like to feel a clear, sharp mind. I like to master my vocabulary. My mind isn't sharp on marijuana, and on marijuana, I can't form sentences, and certainly not write articles. I just drift off.

This can be good for relationships. But if taken as aphrodisiac, marijuana dosages should be comparatively small. But even on a small dosage, marijuana is unpredictable.

Tongkat ali by itself is predictable, and a tongkat ali stack that also incorporates butea superba, velvet beans (Mucuna pruriens), and krachai dam is very predictable. You will have more relationships interest, and your orgasms will feel better.

Underestimated marijuana

The trend in the Americas and Europe is to legalize marijuana. The consensus is that the war on drugs was a failure, not interrupting the use of the drug, and only enriching criminals.

Legalizing and taxing marijuana, so the sounded (and sound) idea, would earn governments much-needed cash, save enormously on enforcement cost, and reduce organized crime.

Furthermore, marijuana has many medical uses.

It can save epileptic children from certain death. It is believed that marijuana stops the progression of Alzheimer's. Marijuana also interferes with HIV replication.

Legal marijuana will change the world. It will have an impact on humanity that is greater than any other of the big changes since World War II: the Internet, the advent of AIDS, the demise of the Soviet Union, or the rise and decline of the Islamic State.

Legal marijuana will be a whole new world. Because it won’t be used just for epileptic children or Alzheimer's and AIDS sufferers.

Many peoole will use it because marijuana can be a relationships drug if properly combined with dopaminergic and hormonal enhancement. This is what can make marijuana a game changer.

It has to be noted that marijuana's relationships potential will have to be awakened for a large number of users. For most people, the prosexual effect of marijuana is dormant. It can be awakened by dopaminergic and hormonal brain stimulation by tongkat ali, velvet beans (mucuna pruriens), and butea superba.

I actually consider marijuana a waste if not used for relationships. Because the drug is way below its potential if used just for its own sake.

So, once marijuana is legal, the majority of users will be mainstreamers who have never used it, or not since their youth when they were not capable to appreciate the drugs effect on relationships. The majority of users will be those who have not used it in recent years because it was illegal: those not inclined to risk years in jail for a few hours of extra pleasure.

Watch out for the transitory dynamics when marijuana will be legal in some places but not all. People go anywhere for better relationships, and this means, they will go where marijuana is legal.

Tongkat ali and butea superba effects on health

By Serge Kreutz

So far, no explicit negative impact of tongkat ali and butea superba on general health has been established.

But what are negative impacts?

Take for example the habit of smoking tobacco. That has a very clear negative effect on health. Tobacco causes lung cancer and, of course, erectile dysfunction.

Or take alcohol. Alcohol causes liver damage, dementia, and, of course, erectile dysfunction.

Nothing like lung cancer or dementia to fear with tongkat ali or butea superba. And, of course, no erectile dysfunction.

Time to change your life, if so far you haven't.

No more tobacco, no more alcohol, but tongkat ali and butea superba, and, of course, great relationships.

You don't have to worry about negative health effects from tongkat ali or butea superba. The two, consumed at normal dosages, if anything, may make your life longer, not shorter.

Look at some famous tongkat ali users, such as Malaysian prime minister Dr. Mahathir MD.

Or take alcohol. Alcohol causes liver damage, dementia, and, of course, erectile dysfunction.

He is a medical doctor, a tongkat ali advocate, and 93. At age 92, when most people are fully decomposed, he was elected prime minister of Malaysia in a democratic exercise... as opposition candidate.

Buy Indonesian tongkat ali (eurycoma longifolia, pasak bumi) extract

By Serge Kreutz

Tongkat Ali Research, 2019

Indonesian tongkat ali is the elite product of Sumatra Pasak Bumi, and it has been so for about 20 years. We are a serious enterprize, not the kind of run-away-with-your-money operation that dominates the online tongkat ali market. We have put our Indonesian tongkat ali products through a painfully slow and expensive Indonesian government approval process.

If you buy tongkat ali from Singapore (check "Contact us" pages of websites claiming to sell tongkat ali), what you get is slick web design plus lies about professional qualifications of sellers. But the product those people sell is a Chinese kitchen lab output, not tested by government authorities. Mind you: as much as you may despise bureaucracy, health product regulations have been invented for your protection, your health, and your safety.

Indonesian wild tongkat ali has now become very hard to source because most forests on Sumatra have been burned down to make space for palm oil plantations. This burning down of forests has not just enormously depleted tongkat ali resources but has been an environmental disaster and human catastrophy of monumental dimension with about 100,000 fatalities. The catastrophy was underreported because the casualties didn't occur in or after a single event, but happened over a span of several months.

See here for some news reports on the forest fires:

Indonesia haze may have led to 100,000 premature deaths, says report (BBC)

Toxic haze in SE Asia killed 100,000, study says (CNBC)

Haze from Indonesian fires may have killed more than 100,000 people – study (The Guardian)
