Brown fat helps burn calories

Too much fat on the body is more than just a visual problem. It not only increases the risk of cardiovascular disease, diabetes and cancer, but also of a severe course of Covid-19. However, only the so-called white fat is harmful. Brown fat, on the other hand, has a positive influence.

The largest study to date on the subject has proven other positive properties of brown adipose tissue. Scientists at Rockefeller University (USA) were able to use more than 52,000 patient data to show that brown fat helps prevent chronic diseases such as diabetes, high blood pressure, heart failure and coronary artery disease. The study results were published in the specialist journal “Nature Medicine“.

Brown and White Fat: What’s the Difference?

But what is the difference between white and brown fat? A look at the structure of adipose tissue helps to answer this question. There are basically two types of adipose tissue: white and brown. The white serves as an energy store and accumulates in the form of rolls of fat in different parts of the body.

Brown fat cells, on the other hand, give off energy. They burn calories to generate heat and protect the body from the cold. The scientific term for this is thermogenesis. The brown fat has its color from the numerous mitochondria it contains. These small “power stations” in the cells are reddish-brown because of their iron content and give the brown fat its color. The more active they are, the more they stimulate fat burning.

For a long time, medical professionals thought that only babies had brown fat. In order not to cool down, they mainly deposited it on the trunk. Today we know that brown adipose tissue is also present in adults. However, the proportion decreases with age and also varies from person to person. For this reason, researchers have long been looking for ways to multiply brown fat cells and fuel their activity – to prevent obesity, diabetes and heart disease.

Beige fat cells: what is it all about?

A third type of adipose tissue has been known for a number of years: beige-colored fat. These are cells that have a large number of mitochondria, similar to brown fat, but are scattered throughout the white adipose tissue. They are also involved in the generation of heat. However, the thermogenic activity of this hybrid form is weaker than that of brown fat cells.

Brown cells double in the cold chamber

The more brown fat a person has, the more calories they burn. Therefore, people with a high percentage of brown adipose tissue are more likely to be protected from obesity. It generates 300 times more heat than any other tissue in the human body. A lot of calories are burned.

How much brown adipose tissue a person possesses varies from person to person. But cell growth can be supported from the outside. The brown fat is particularly active in the cold. So found Dutch researchers in one study found out that cold can boost fat burning. They let test subjects freeze for ten days for six hours each in a 16 degree cool room. The proportion of brown fat doubled.

On average, a young adult has only 50 grams of brown fat. If the cells can be activated permanently, they burn around 200 to 400 kilocalories per day. Converted to the year, this means the loss of around 16 kilograms of white adipose tissue.

Freezing Weight Loss: Does It Work?

Anyone who wants to lose extra pounds should therefore consciously expose themselves to the cold from time to time. Even small changes in lifestyle can have an impact. This includes, for example, not turning up the heating in the apartment above 19 degrees or briefly taking a cold shower after a hot shower. Both measures can help to raise the body’s own “heating” in the adipose tissue and thus burn more calories. In addition, the low temperatures help you automatically move more to keep warm. That also increases the calorie consumption.

However, one should not expect miracles from the measures mentioned. In addition, it is unrealistic for people to voluntarily freeze over a long period of time. Certainly, calorie burning can be accelerated to a certain extent through a “thermogenic” lifestyle, but it comes with being very overweight Weight lossmethod quickly to its limits. If you want to reduce your weight permanently and in a healthy way, you can usually not avoid changing your diet and getting active.

Food also activates brown fat cells

Scientists from the Technical University of Munich (TUM) and the University of Turku (Finland) have jointly agreed that the brown fat cells can be activated not only by cold, but also by eating study found out. According to the information, the same subjects were examined twice for the study: once after exposure to cold, and a second time after consuming a high-carbohydrate meal. There was also a control group.

“It was shown for the first time that the generation of heat in the brown adipose tissue is activated by a test meal in the same way as by exposure to the cold,” says study leader Martin Klingenspor. However, it is still unclear how this effect can be used to prevent obesity and which nutritional components play the decisive role. Further studies are therefore planned.

France: Champagne has champagne and pig’s feet

The region

Dhe Champagne is a historic landscape in northeastern France that is famous around the world for its sparkling wine, which can only be called champagne if it was produced in the region.

The cultivation area was determined in 1927, it covers only a small part of the total agricultural area. Around 300 million bottles of bottle fermentation are produced here each year, mainly from grapes of the Pinot Noir, Pinot Meunier and Chardonnay varieties, almost half of which the French drink themselves.

The most important wineries and the champagne capitals Reims and Épernay are today by the Champagne Tourist Route Connected to each other, it criss-crosses the hilly landscape over a length of 600 kilometers.

If you don’t just want to spend your days in wine cellars and tastings, there are other attractions in the area that was declared a World Heritage Site in 2015: for example the Notre-Dame de Reims cathedral, where the French kings were crowned until the 19th century, or Troyes old town, famous for its half-timbered houses.

Crocodile fabric

Before champagne gave wings to the local economy and tourism, Champagne was a center for textiles in the 16th and 17th centuries.

What remains of it: Lacoste produces clothing in Troyes – as one of the few companies in France. The Made-in-France collection with the well-known crocodile logo, in addition to polo shirts, t-shirts and hoodies.

Monk with bottle

In front of the steps to the altar of the abbey church in the village of Hautvillers, nicely situated in the hilly landscape of Montagne de Reims, a simple grave slab is set into the ground. Dom Pierre Pérignon, who was stylized as the “inventor” of sparkling wine in Champagne, is buried underneath.

In any case, the Benedictine monk was instrumental in ensuring that the pearly bubbles lingered in the wine when he experimented with bottle fermentation in the 17th century. This procedure is called Champagne method went down in history.

The reason for filling the wine in thick-walled bottles was originally pragmatic: it was easier to transport than in barrels. The actually unintentional fermentation initially turned the bottles into small bombs that blew up every now and then during the trip. For fear of explosions, the cellar masters wore iron masks.

A life-size statue of Dom Pierre Pérignon stands in Épernay in front of the Moët & Chandon house, which has named a champagne brand after him.

Church with a lake

You can also swim in Champagne – in Lac du Der-Chantecoq, France’s largest reservoir, almost half the size of the Müritz.

It was dammed from the mid-1960s to protect the Marne Valley and Paris from flooding. Three villages sank into the floods, the church of Champaubert was preserved by a dam.

The remains of several villages can be found at the bottom of the lake

The lake was inaugurated in 1974. Bathers and birds soon discovered the new body of water in the sparsely populated northeast. Its banks now line campsites, beaches and a harbor for pleasure boats. Some guests let themselves be Champagne picnic low.

Bird lovers enjoy the spectacle in autumn, which more than 200,000 cranes organize during their rest at the lake on their way to North Africa year after year.

Breaded feet

A lot sounds tempting in French, including the name of this specialty: Pieds de porc à la Sainte-Menehould. You get served Pig feet, cooked in bouillon and then breaded.

The feet of the French King Charles VII are said to have been shaken during a visit to Sainte-Menehould. Many restaurants in the village still have this delicacy on the menu.

100 Kilometer

That is how long the labyrinth of champagne cellars is alone in Épernay. The entire length of the rock tunnels in Champagne, in which the bottles are kept cool, is unknown.

Part of the aisles was already around 2000 years ago dug into the limestone rock – by the Romans, who had already planted vines in Champagne.

The quote

“Great love affairs start with champagne and end with herbal tea”

Honoré de Balzac (1799–1850), the author of these words, was considered a bon vivant who is said to have sipped tons of sparkling wine with his muses. It is not known whether the same amount of soothing tea flowed. On the other hand, Balzac’s penchant for another hot beverage is known: he is said to have drunk up to 50 cups of coffee per day of writing.

Lose weight: New Year’s day without trend diets? – Health

One of the less obvious side effects of the corona pandemic is the absence of rituals that are otherwise repeated annually. Some of them – Christmas with the whole family, for example – was a real shame. But now the holidays are over and after a New Year’s Eve without firecrackers madness you can hopefully look forward to a January in which the notorious, but certainly most superfluous element of the post-Christmas period is as meager as possible: the diet. Better still: the trend diet.

The trend diet has the fact that it claims to be scientific. Very modest, for example in the form of a “protein lever”. as is the case with modern forms of Atkins such as low-carb. Or maybe a little more elaborate, maybe something with chronophysiology, you would have ended up with intermittent fasting and thus the undisputed leader of the previous year. After all, you don’t have to remember a lot if you are only allowed to eat in fixed periods, but then as much and what you want. And yet this diet magically promised to activate a biological mechanism that either causes fat deposits to go up in flames or melt.

The only scientifically proven fact is that no diet helps in the long run – in the best case scenario

With diets, the promise is always one thing, the reality is another. In any case, it has only been scientifically proven that no diet helps in the long term – at best. Sometimes an abnormally reduced or temporally concentrated food intake is even more likely to lead to even more body weight via dangerous yo-yo-effects. Which is neither desirable nor healthy.

It would not be sad at all if, in view of more pressing problems, the latest trend among body scales fetishists simply fell under the dining table. “Sirtfood” is its name, and the supposedly scientific basis of this diet is as crazy as the name. It’s about so-called sirtuins, which have already been touted as anti-aging enzymes, and as a component of food are now also supposed to make you slim, i.e. burn fat.

But even if a biological or synthetic molecule could do this at all, there is a well-known process that effectively prevents such magical enzyme effects and it is called digestion. This includes that proteins, which also include enzymes, are denatured and broken down so that the human body can utilize them – for the gain of energy, not its destruction. In the end, what matters for weight is the sum of this energy, which can be measured in calories and permanently reduced to a beneficial level. Which one could turn to more pressing problems. For example the pandemic.

In 2021 turn your healthy challenges into habits – Local News, Police, about Mexico and the World | The Sun of San Juan del Río

Reduce alcohol consumption, exercise, practice meditation, stay hydrated, take more walking steps, eat less meat and more vegetables, make conscious use of technology, eat less sugar, do body stretches, go to bed earlier for a good night’s sleep , laugh often ….

These are some of the habits that most medical, wellness and psychology professionals recommend incorporating into our lifestyles to enjoy better physical and mental health, and also some of the goals that are often part of the classic list of resolutions that we consider when one year ends to put it into practice the following year.

They are also the cornerstones of the ‘plan to be happier, healthier and fitter’, proposing a single challenge each month, as described by the doctor Jennifer Ashton, gynecologist and obstetrician, health delegate of the American television network ABC News, in his ‘Book of Self-care’.

Whether you consider these changes as healthy New Year’s resolutions, or if you decide to apply Ashton’s twelve-month plan in 2021, it is in your best interest to follow the recommendations of this renowned American physician and popularizer to turn those health and wellness challenges into habits for lifetime.

Ashton (https://jenniferashtonmd.com) invites you to take each month as a personal experiment and give yourself the opportunity to explore how to be the best version of yourself every day, with these tips to, according to, “change in an easy way and natural ”:

1.- USE A WALL CALENDAR

“Visualizing our progress will motivate us to successfully meet our annual health and wellness challenges and help us turn them into lifelong habits,” according to Ashton.

Explain that this little trick works like this: “place a large wall calendar, the traditional ones, in the most visible place on your floor (in the kitchen) and write down the drinks you drink each week, the number of steps you take, the days you meditate or the type and duration of your ‘cardio’ gym sessions ”.

“So you can quickly calculate how much alcohol you drank, how many days you have exercised and what type of training, and how many days you have not meditated, for example,” he says.

“Noting our behavior in a visible place makes us take responsibility for each of these practices every day,” he says.

2.- YOUR HEALTHY HABITS ARE PRIORITIES

This doctor advises considering physical exercise as a non-negotiable part of the day, something that you simply “have to do for your basic health and well-being, as imperative in your day as brushing your teeth.”

He also recommends applying the same mindset with habits like hydration, sleep and eating more vegetables, “daily practices that should be as essential as showering or dressing.”

“Surely you will never go to work without having showered and dressed in the right clothes. By the same ‘rule of three’, you shouldn’t let a day go by without trying to move, drink enough water, get enough sleep and eat more vegetables ”, emphasizes the Englewood-based physician (New Jersey, USA).

3.- THINK YOU WILL ONLY TRAIN A FEW MINUTES

“Whether we don’t have time or we don’t feel like it, trying to exercise for just five minutes on the treadmill or on a bicycle can have great benefits and turn our mood and mind around, encouraging us to exercise for longer”, according to Ashton.

“If, for example, you don’t feel like doing push-ups, convince yourself to just do one rep. That is better than doing nothing and maybe, as soon as you have started, you will want to do something else to take advantage of the fact that you are already on the ground ”, he adds.

“The same goes for walking or doing any type of physical activity: setting low expectations when you have little time or little motivation is one of the easiest and most effective ways to get going and keep up,” he emphasizes.

4.- FIND DELICIOUS ALTERNATIVES

“If our challenge is to eat less meat and more vegetables, or to eat less sugar, it is vitally important to discover delicious and healthy alternatives so that we do not obsess over what we cannot eat,” according to the Englewood doctor.

Ashton notes that when he stopped eating red meat, he stopped missing it after discovering smoked salmon with cream cheese, and acknowledges that he would have been much more successful in his low-sugar mission if he had had some vinegar strawberries on hand. balsamic when tempted by mouthwatering French pastry cookies.

“The process of finding new foods that you might like as much as the ones you are trying to avoid is fun. You just have to focus on alternatives that are accessible in your day to day, fit your budget and enjoy them ”, he recommends.

5.- USE VISUAL AID TO HELP YOU

Dr. Ashton has a closet full of clothing and accessories, many of which rotate seasonally or as styles change, but the only accessory that is always there is her bright orange foam roller, which she keeps there for remembering to stretch, he says.

“Every time I see that roller, I remember how good stretching feels to me, and that makes me pull it out regularly. Each person can find their own visual stimuli that motivate them to maintain their healthy habits ”, he adds.

6.- AND KEEP LAUGHING, ALWAYS AND FOREVER

Ashton invites us to seek the joy of life and to realize the “miracle that is our body”, everywhere, every day and in everything we do.

“One of the best promises and palliative for health in general is the happiness that is created from within, and not with external factors such as money or the success of your professional career,” he says.

“Recognizing what the incredible machine that your body is does one day after another and thanking for having it in that state, even if you want to aspire to more, is a reason for joy”, proposes this expert

“There is always joy around you and in you. Take the time to find and celebrate them every day. This is my recipe for well-being, following the saying of ‘Doctor, heal yourself’ ”, he concludes.

That is why it is extremely important to carry out this activity because it has been shown that thanks to exercise you can have better performance and not only physical but also work.

This is explained by Cinthya Pulido, Specialist in Physical Education and Sports, as she mentions that physical health helps to have a better quality of life, in addition to avoiding chronic and cardiovascular diseases.

“Doing physical activity is a nice way to stay connected to your social circle”

In children and young people, physical activity is key to controlling weight, in addition to providing benefits in aspects such as managing stress, freeing the mind and relaxing.

Basic routine to exercise at home

The current situation cannot be an excuse to become sedentary. On the contrary, we should block at least thirty minutes a day to exercise, especially those over 30 years old.

Well, you don’t need space, weights, or devices, as Cinthya pointed out, because you can do any physical activity at home, and now with technology people can support themselves with basic internet routines in addition to using materials with the that they already have at home.

“Not every day you are motivated and that’s fine, rest but don’t quit”

Without excuses

Is your hallway short? Walk, jump or run on the toes. At least six to ten minutes per session (music helps a lot) twice a day, once in the morning and once in the afternoon ”.

Don’t have weights? have a one or two liter bottle of water (each one knows what they can or should work with) in each hand and repeat the exercises you would do in the gym ”.

What do you want to do is work your legs? Well go ahead! Put your back to the wall with your legs forward and semi-bent and lower yourself as if you were sitting on a chair … you will see how your quadriceps burn!

Does it really help you lose weight? – healing practice

Blood Type Diet: Does It Help You Lose Weight?

Right now, after Christmas and the upcoming New Year, many people are thinking about how to reduce their weight. A nutritionist recently pointed out which diets are unhealthy and won’t help you lose weight. She also mentioned the so-called blood group diet. Researchers from the USA have now published new findings on this diet concept.

In the 1990s, the so-called “blood type diet” gained worldwide attention. According to the alternative medical diet concept, which is based on the theory of the American naturopath Peter J. D’Adamo, everyone should base their food on their own blood group. The aim is to improve health and well-being and reduce the risk of illness. However, as is often claimed, this “diet” cannot help lose weight, as a new study now shows.

Diet adapted to the blood group

D`Adamo, who has also published books on the subject, claims that blood type helps determine which foods people tolerate best. The reason for this are lectins. Among other things, these proteins are said to stick together blood cells and cause organ damage.

According to the author of the book, people with blood group 0, for example, should mainly eat meat and fish, while those with blood group A eat vegetable foods. Therefore it is easier to lose weight with a diet adapted to the blood group.

But a new study by Neal Barnard of George Washington University and his colleagues from the Physicians Committee for Responsible Medicine (PCRM) – a non-profit organization of 12,000 doctors – has now exposed the “blood type diet”, according to a statement dated PCRM.

Effects on body weight

This new study, which was published in the journal “Journal of the Academy of Nutrition and Diets”, is based on a randomized control study, the main results of which were published in the journal “JAMA Network Open” at the end of November.

In this study, 122 overweight participants of different blood groups and without diabetes ate a low-fat and purely vegetable diet for 16 weeks. The other 122 people in the control group did not change their diet.

The scientists wanted to know how this diet affects body weight, body fat percentage, plasma lipid concentrations and blood sugar control, among other things.

Plant-based diets are beneficial for everyone

The most important finding is that a plant-based diet increases the metabolism. This effect was stronger in the test group than in the control group. Accordingly, the participants in the intervention group burned an average of 18.7 percent more of the calories consumed after meals.

In order to test a possible connection between blood group and diet, the researchers took the additional step of performing a secondary analysis among the participants in the intervention group.

They investigated whether the effects of a herbal dietary intervention on body weight, blood lipids, and blood sugar control were related to blood type.

The “blood group diet” recommends a mainly plant-based diet for people with blood group A, while it recommends a meat-rich diet for people with blood group O, he says.

“We found that the blood type makes no difference,” said study author Neal Barnard, President of the PCRM. “While the blood type diet says that a plant-based diet is better for blood group A and less suitable for blood group O, it has been shown to be beneficial for people of all blood types, and there has been no evidence that a meat-rich diet is good for anyone” , explains the expert.

No significant differences

According to the information, the values ​​between people with blood groups A and non-A and the values ​​between participants with blood groups 0 and non-0 showed no significant differences.

The test subjects of blood group A lost an average of almost six kilograms of body weight, while participants of the other blood groups lost around seven kilograms.

And when it comes to the percentage of body fat, the participants in all blood groups lost an average of around four grams of fat.

In addition, the mean total cholesterol level fell in the test subjects with blood group A, as in all others, by around 17 milligrams per deciliter. The participants with blood group 0 also had no significantly worse effect – despite the vegetable diet that was supposedly unsuitable for them.

“Our research shows that all blood types benefit equally from a vegan diet based on the consumption of fruits and vegetables, legumes and whole grains when specifically looking at weight loss and cardiometabolic health in obese adults,” says Barnard. (ad)
