Bоdу аdjuѕtmеnt tо thе ketogenic diet

7:33 AM
The human body nееdѕ three wееkѕ to соmрlеtеlу аdjuѕt tо thе uѕаgе оf fatty асidѕ аnd ketones аѕ аn еnеrgу ѕоurсе.
If уоu trу thе kеtоgеniс diеt only for thе first few days, you might feel likе hеll!
Yоu might nоt bе able tо соnсеntrаtе, you might feel nаuѕеоuѕ аnd weak. Thiѕ iѕ because thе bоdу needs some timе tо аdjuѕt to thе nеw еnеrgу ѕоurсе.

The body iѕ uѕеd tо саrbоhуdrаtеѕ аnd if you juѕt lоwеr уоur саrbоhуdrаtеs tо zеrо, thаt will bе a big ѕhосk.
But when thе bоdу adjusts уоu will ѕtаrt bеnеfiting frоm the kеtоgеniс diеt.
Whеn уоu start еаting a high fаt аnd lоw саrbоhуdrаtе diеt, уоu will ѕtаrt influencing mаinlу two important hоrmоnеѕ, inѕulin аnd gluсаgоn.
Inѕulin plays a role in thе trаnѕроrtation of nutriеntѕ frоm the blооdstream tо cells (likе gluсоѕе to muscles).

Glucagon acts аѕ аn орроѕitе , it influences thе сеllѕ to starts releasing thе ѕtоrеd nutriеntѕ towards thе blооd stream.
Whеn there is a ѕhоrtаgе of glucose it еnсоurаgеѕ thе livеѕ tо рrоduсе gluсоѕе from оthеr ѕоurсеѕ аnd their rеlеаse in thе blооdstream, from where thеу саn rеасh аnу сеll in the bоdу.


If уоu lower the саrbоhуdrаtе intаkе, thе bоdу gradually ѕtаrtѕ rеlеаѕing lеѕѕ and less inѕulin аnd mоrе gluсаgоn.
Thаt and thе ѕmаll ѕtоrаgе оf саrbоhуdrаtеѕ in thе blood, ѕооn ѕtаrtѕ tо rеlеаѕе fаttу acids frоm thе body fаt dероѕitѕ аnd trаnѕроrting them tо the livеr whеrе they аrе metabolized.

That leads tо the inсrеаѕе in kеtоnе рrоduсtiоn, thereby рutting thе bоdу in thе ѕtаtе we саllеd ketosis.
As you may have understood, this diet аѕ ѕоmе реорlе claim, ѕhоuld nоt bе саllеd a diet in thе firѕt рlасе but a mеdiсаl intervention, and should hence be followed with the aid of a doctor, nutritionist or expert physician.

It is in your complete interest that I stress that with this book my aim is to provide you with all the knowledge necessary to orient yourself within the vast clutter of knowledge that exists on this topic, and even be able to understand if your physician is a specialist on the topic or not, but I personally recommend you start a ketogenic diet only with the aid of a good professional.

Physiological ketosis

7:08 AM
Physiological ketosis
The term "physiological ketosis" was coined in 1966 by Hans Krebs, the father of modern biochemistry, to distinguish it from pathological ketoacidosis, characteristic of type 1 diabetes,
as well as to emphasize that ketones serve as an efficient energy substrate.

Often, low carb/ ketogenic diets are denigrated, because of the phonetic similarity with ketoacidosis and because of a general lack of information on the topic and its identification with a pathological condition actually outside of the normal metabolic state.

This common mistake of interpretation has often been reported by the scientific literature on the topic, and researchers have officially judged physiological ketosis as harmless for health.

Ketogenic diets are in fact currently been used for research on the treatment of many serious diseases including insulin resistance, type 2 diabetes, cardiovascular disease, obesity, cancer, epilepsy, and other neurological diseases, just to name a few.

The first therapeutic use of the ketogenic diet dates back to the 1920s, as we mentioned in our Introduction, in the treatment of epilepsy especially in children, condition for which it is still used today since the presence of ketones in the blood has been found to lower the risk of epileptic attacks.

It would appear to be a major contradiction if, in the research for curing diseases, pathological patients were exposed to a presumed pathological metabolic state Interested parties can consult the relevant scientific documents that deepen the extensive use of ketogenic diets for the treatment of pathologies on PUBMED (https://www.ncbi.nlm.nih.gov/pubmed/).

The main difference between physiological ketosis and pathological ketosis lies in the actual ketone concentrations in the blood (ketonemia).
Physiological ketosis never registers a harmful level of ketones in the blood, thanks to various feedback (control) mechanisms in our body that ultimately create a neutral balance, including the work of insulin (impossible in ketoacidosis linked to Type 1 diabetes but perfectly functioning in a healthy subject) and the efficiency of the central nervous system and other non-liver tissues in oxidizing ketones.

Forms of pathological ketosis are potentially fatal. In detail, the significant and well-known differences claimed by technical publications on the issue state that ketones must not exceed a concentration of 7-8 mmol/ decile in plasma (physiological ketosis due to diet or fasting), while in diabetic ketoacidosis ketonemia reaches levels of about 20-25 mmol/ deciliter (more than three times the phisiological value). In addition, ketonemia gradually decreases in dietary ketosis by stabilizing at minimum levels within 10-12 weeks.

It should be pointed out that concentrations of pathogenic ketones do not occur in a non-diabetic or a non-alcoholic subject.
In addition, in physiological ketosis, blood pH remains within physiological ranges, while lowering in diabetic ketoacidosis.

So, to wrap up, ketogenic diet is based on the creation through diet of a physiological ketosis condition, in which ketones remain within a healthy range in our blood without jeopardizing our health.

You can read pretty well anywhere that a nutrition rich in protein and lipids, and at the same time very poor in carbohydrates, should keep insulin levels constant avoiding the accumulation of fat and promoting its use for energy purposes.
But decreasing glucose levels beyond the recommended limits, needs to be done knowing exactly what is going on.

Physiological ketosis vs. pathological ketosis

7:03 AM
Physiological ketosis vs. pathological ketosis
A point that too often is improperly treated by low carb diet detractors, as well as by many books on the topic, is the nature of ketosis.
In many websites or publications, the authors erroneously confuse forms of physiological ketosis with pathological/ symptomatic ketosis or ketoacidosis.

Forms of pathological ketosis can be divided into: diabetic ketoacidosis, a characteristic of type 1 diabetes, and alcoholic ketoacidosis, present in alcoholics.

The use of ketone bodies for energy anyhow, as mentioned, occurs daily in physiological conditions such as morning ketosis and ketosis after work out or physiological ketosis after a rich protein meal.

The Ketogenic diet: all you need to know about the basics

The Ketogenic diet: all you need to know about the basics
What is a Ketogenic diet

The aim of a Ketogenic diet is to send your body into a process called ketosis, in which carbohydrates cease to be used as a fuel for your body, which instead uses ketones.
Ketones are produced by our liver in certain dietary conditions, that in the case of Ketogenic diet is a nutrition based fat, an adequate amount of protein and very low carbohydrates.

Ketosis is a physiological condition
Ketosis is actually a metabolic condition.

The physiological function of ketosis is to provide the heart and the central nervous system with high-energy metabolic substrates during the periods of reduced glucose availability: thanks to this mechanism, ketones have allowed our ancestors to survive and remain efficient even when they did not have anything to eat.


The Paleolithic and mesolithic age

Up to 8,000 years ago, our ancestors lived alternating periods of abundant eating and nearly complete fasting, due to the unavailability of food.
This meant a cyclic intake of high levels of animal protein (when favorable hunting occurred), with low fat content (consumption only of wild animals).

These fluctuations have greatly influenced our metabolic patterns, which have been gradually disoriented by the constant availability of food, already appeared with the advent of agriculture about 8,000 years ago.
The increased tendency to insulin resistance has been correlated in various studies with the suspension of this alternation between fasting and satiety, resulting in a reduced ability to preserve glucose for vital functions such as cerebral activity and reproduction.


What exactly is Ketosis

When drastically reducing carb intake, the modification of the ratio between insulin concentration and glucagon concentration in our body promotes the mobilization of lipids from tissue deposits, promoting oxidation for energy needs.
Since the conversion of glucose into pyruvate (pyruvate is a molecule that our body can build glucose from through a process called gluconeogenesis) is slowed down, acetyl-Co-A (a molecule that participates in the biochemical reactions in protein, carbohydrate and lipid metabolism.

Its main function is to deliver the acetyl group to the Krebs cycle to be oxidized for energy production.) is predominantly shifted to the production of ketone bodies.


Ketone bodies and ketones

Ketone bodies are 3: acetoacetate (AcAc), β-hydroxybutyrate (β-OHB), and acetone. These elements are produced from fatty acids, or rather from their metabolic intermediates, or from the accumulation of acetyl-CoA in the mitochondrial matrix of hepatocytes (in liver cells).

More precisely, from a molecule of AcAc (composed by two molecules of acetyl-CoA), β-OHB and acetone are created.
Among these two, β-OHB is the main circulating ketone, while acetone is mainly eliminated through breathing.
Ketone bodies can be used as energy substrates by all tissues that have mitochondria (organelles found in all eukaryotic organisms, which generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of chemical energy), such as the brain and skeletal muscle, but not by the liver.

The main role of ketone bodies is actually to replace glucose as a substrate of lipidic energy for the central nervous system.
The central nervous system, in fact, under "normal-glucose" feeding conditions (regular carbohydrate consumption above certain minimum levels) is defined as a "glucose-dependent" tissue, due to its inability to use fatty acids for energy purposes.

The central nervous system, however, is able to adapt perfectly to the use of ketone bodies for energy, when carbohydrates are lacking in a diet for a relatively long time (a few days).

Ketones should not be considered a toxic substance or an abnormal by-product of human metabolism.
Rather, ketones are normal physiological substances that play many important roles in the human body.

In a healthy person, different kinds of ketosis may occur: "dietary ketosis" (during a ketogenic diet), "fasting ketosis" (during a prolonged fasting period), and post-exercise ketosis (which occurs exceptionally as a result of prolonged aerobic activity, if practiced for a rather protracted period after a few hours of fasting or deprivation of carbohydrates).
These are all non pathological conditions.

The Calorie Conundrum – Are All pounds Created Equal?

The Calorie Conundrum – Are All pounds Created Equal?
Although research indicates that diets are only as successful as their consistency, many people beg to differ.
And this should be no surprise. After all, there are a million diets for a million reasons.
Some people want to eat more raw vegetables. Some people want to improve their heart health, or their brain power, or completely eliminate fat.
Other people are anti-carbs, some people want to mix it all together, and certain eaters believe that nothing but marbled steaks is the path to eternal salivation and weight loss salvation.

Because most popular diets are based on their own frameworks of scientific evidence, there is never a  shortage of reasons to give them a go.
While the main predictor of weight loss is adherence, in certain cases, there just might be credence to one diet over another.
That said, you have to be careful. Weight loss doesn’t necessarily mean better health. And sometimes, there’s just not enough evidence to tell one way or the other.

Consider the unique case of the Twinkie Diet.
That’s right, the “Twinkie Diet.” Never heard of it? Well, then prepare yourself.
When a Professor Haub of human nutrition decided to go on a 10-week diet, he made a special commitment to himself: junk food would become his main food.

Immediately, he began to eat twinkies and donuts, doritos, cookies and sugary cereals. Of course, there was a catch. Haub believed that the nutritional content of his food would not matter, so long as he consumed less calories than he burned.

Therefore, he consumed 1800 calories, 800 beneath the typical 2,600 daily consumption of a man his size. As the diet progressed, his received the majority of his calories from junk food.
But there was something healthy to his method.
Every day, Haub made sure to take a multivitamin pill, drink a protein shake, and eat green vegetables such as beans or celery.
By the end of his 10 week experiment, he had shed almost 30 pounds, his body fat dropped almost 10%, and his good and bad cholesterol levels had increased and decreased 20%, respectively.
Despite everything he thought he knew about dieting, Haub’s ‘Twinkie Diet’ seemed to be improving his weight and his health.

Of course, this is just one case for one man. Although Haub attributed the weight loss to portion control, what he couldn’t explain was if he was truly healthier as a result. There was no telling what carcinogenic results could stem from his efforts—or what illnesses could arise if he sustained such a diet longer.
Or better yet, if biological markers such as body fat, cholesterol and BMI are even accurate measures of health to begin with.

This is where things can get sticky. Most experts agree that if you’re going to lose weight, you might as well opt for foods that are nutritious.
While many people hop on fad diets that promise to shed weight no matter the food, these can be deceiving. Chances are, you’ve seen the documentary Supersize Me, about the man who eats nothing but McDonalds for 30 days straight. Although he could have theoretically eaten less calories every day and lost weight instead of gaining like he did, it’s likely that he would have felt terrible doing so.
This is because certain highly processed foods simply make us feel bad.

They lower our energy levels, ruin our moods, and bring on bodily problems such as headaches, lethargy, fatigue, cramps, gastrointestinal issues, and potentially chronic diseases.
They may enable weight loss, but the real question is: do they enable weight maintenance?

That is to say, are there certain diets that are better at keeping the pounds off once we’ve lost them? Diets that make us feel good and allow us to continue on the right track? Diets that are easier to adhere to than others, even if others may guarantee quicker but unsustainable results? The research may surprise you…

How to Choose a Good Crock-pot and Where to Buy One

6:19 AM
How to Choose a Good Crock-pot and Where to Buy One
Choosing the ideal crockpot is very important and there are several factors to consider:
#1: Choose a crockpot that has its crock not just sitting below the heating unit because you have to stir even more. Choose one with a crock insert extending beyond the heating unit.

#2: The crockpot must be easily removable for cleaning, whether it is porcelain, ceramic, or metallic.

#3: Shape may not matter, but round and oval crockpots seem to be more convenient for most users.

#4: Size may matter, especially if you have a small or large household. For larger households, choosing a larger crockpot means you can add more recipes, but single individuals or those with smaller households can choose smaller crockpots.

#5: Extras such as sear functions may add to the price of crockpots, but they can be helpful in sautéing onions and browning meats. Built-in digital timers may also offer extra advantages for cooking.
