Losing 10 Pounds Using Cardio Workout

Thursday, December 31st, 2009

cardio workoutOne of the best ways on how to lose 10 pounds fast is to do cardio workouts. Providing that you understand what you are doing, this could be very helpful. However, the fact is that lots of individuals, unfortunately, still don’t get it. For that reason, large number of people who go to the gymnasium and spend very much time on cardio machines, end with little expected effects. Definitely, it is because of the fact that you don’t adopt your cardio program correctly so as to accomplish the supreme weight loss results.

A large number of people have discovered that in order to get rid of fat, they need to do cardio at a proper pace that will bring their heart rate to a specific range called the “Fat Burning Zone”. It, necessarily, involves doing medium cardio workouts. Then, we are suggested to continue with doing cardio and stay in “the zone” for at least 20 minutes to achieve any results.

Still, what was not told us is that because the Fat Burning Sector is accomplished with medium power workouts, our body stops burning a huge number of calories almost immediately after we end every session. Also, it was not told us, if we did high power exercises, our body would’ve continued burning a huge volume of fat during its recovery period. It would’ve lasted for hours after you have taken out an after workout shower. This means that even though we were burning less while we were doing exercises, we finished with reducing more fat afterwards, that is a good deal more effectual.

And then we reach the hint why we need upper power interval cardio exercises. For a while we do full power workouts, after which we slow down to average power for a few minutes in order to catch our breaths, and then keep on doing again. Surely, it is a good view of how to lose 10 pounds fast, isn’t it?

Type-two diabetes limb amputations rise dramatically

Wednesday, December 30th, 2009
By Emma Wilkinson
BBC News health reporter

The number of people in England having a limb amputated because of type-two diabetes has risen dramatically, a study has shown.

Diabetes can lead to damaged feet and toes

Between 1996 and 2005, below-ankle amputations doubled to more than 2,000, and major amputations increased by 43%.

However the number of amputations in people with type-one diabetes dropped, an Imperial College London team found.

A charity said more early diagnosis was needed, as diabetes can go undetected for more than 10 years.

The number of people diagnosed with type-two diabetes had increased greatly in the past decade, which could partly explain the findings, the researchers said.

In the UK, 2.35 million people have type-two diabetes, which is caused by the body not properly responding to the insulin it produces, and is often a result of lifestyle factors such as obesity.

Along with complications such as heart attacks and strokes, people with diabetes are far more likely to develop foot problems, including ulcers, which can become infected and lead to gangrene.

Writing in the journal Diabetes Research and Clinical Practice, the researchers said the number of the most major amputations, above the ankle joint, had risen by 43%.

And the average age of those having above-ankle amputations fell from 71 to 69 years, which followed the pattern of people being diagnosed younger, they said.

More men underwent amputations than women, a gap that widened during the 10-year period.

Study leader Dr Eszter Vamos said they had expected to see long-term complications of diabetes rising to some extent because the number of people diagnosed with the condition had increased.

"But at the same time there is very strong evidence that with a multidisciplinary team approach you can prevent up to 80% of the amputations.

"It highlights the importance of frequent foot checks and that it is very important to get glycaemic control and blood pressure and cholesterol control."

Diabetes UK care manager Sara Spiers said there were about 100 diabetes-related amputations each week in the UK.

"The findings of this study are especially interesting because they indicate a particular rise in the number of type-two diabetes related amputations," she said.

"This rise could be for a number of reasons, including type-two diabetes not being diagnosed early enough, people not getting the education they need to manage their condition effectively, and swifter treatment of foot problems, meaning people are more likely to have an amputation than die because of foot ulcers."

She added more early diagnosis was needed, as the condition could go undetected for more than 10 years and most people already had complications when they were diagnosed.

“Shouldn’t You Be Eating Healthy To Lose Weight?”

healthy foods to lose weightIf you put on a size 14 and you blow a hefty sum on designer size 8 dresses as motivation, you will probably end up feeling guilty, infuriated, and angry if you are not fitting in it a month later.

In reality, you will be much better setting smaller, achievable targets for yourself. If you must try the new-clothes way, go down a size at a time, and do not buy anything you have to take out a second mortgage to settle.

If you want to get into that smaller size

Then Start To Be Eating Healthy To Lose Weight

Because, if you continue to be concerned on losing weight fast, you will end up incorporating fad diets or those that offer quick weight loss.

For most people who are not familiar with this fact, there are no such methods as quick weight loss diets and there is no instant weight loss for patients who want to be slimmer than what their body can provide.

The problem with most people is that they want to opt for fast-forward fixes wherein fact these methods are not fruitful at all.

What Will Not Work

Today, there are loads of weight-loss strategies that are most assuredly to backfire. This is because these swift fixes instilled on certain diet programs are, in reality, not useful because they do  not employ the right principle and the right attitude in losing weight.

These speedy weight loss diet procedures are known as fad programs because that is in really what they are, just a fad. In time, when fashion is dead and popularity dips, people will come to know that the diet they have depended on is not reliable at all.

To know further about these fad diets that are selling like hotcakes in the market today, here is a list of some telltale signs that would caution you not to try it even once.

A Short Checklist:

1. Skipping breakfast

Does your diet program require you to skip meals? If it does, then, it is a fad diet.

Abstaining from food completely is not a healthy practice. It may even lead to some serious inconveniences or problems especially for people who are suffering from diabetes.

If you are really concerned about your weight then choose  A Healthy Option Today

Skipping meals will only give way to a hypoglycemia, or the condition wherein your blood sugar is really alarmingly low, and will truly only be effective in making you eat twice as much at the next meal.

2. Dieting devoid of exercise, or vice versa

Exercise is cardinal to the human body. It is important in perfect blood circulation and other processes of the human body system.

Therefore, diet habits that do not require you to exercise are useless. We are born to be active.

But then again, exercise alone is not fruitful. Hence, it would be appropriate if diet and briskness will go hand-in-hand.

3. Continuous delaying

There is no better period to start reducing weight. If you wish to really put off those excess fats, you have to begin now.

Delaying tactics will not get you anywhere and will only make the problem severe. So, if your diet method suggests a certain timeframe for you to start losing weight, chances are, you are incorporating the trend of fad diets.

To put it short, it is best to rely more on the way you feel than the tale of the tape. This means that if the weighing contraption tells you that you are shedding weight even if it is slower than you would desire, but you are feeling upbeat and positive about your weight-control efforts, then, you are just doing fine.

As explained and is worth stating all over again, weight loss is not a quick process.

Group exercise ‘boosts happiness’

Sunday, December 27th, 2009
BBC News

Exercising together appears to increase the level of the feel-good endorphin hormones naturally released during physical exertion, a study suggests.

Rower
They may feel happier than if they were on their own

A team from Oxford University carried out tests on 12 rowers after a vigorous workout in a virtual boat.

Those who trained alone withstood less pain - a key measure of endorphins - than those who exercised together.

Writing in Biology Letters, the authors speculate these hormones may underpin an array of communal activities.

Row your boat

It has long been known that physical exertion releases endorphins and that these are responsible for the sometimes euphoric sensations experienced after exercising.

They have a protective effect against pain.

But researchers from Oxford University's Institute of Cognitive and Evolutionary Anthropology found this response was heightened by the synergistic effect of rowing together.

After 45 minutes of either rowing separately or in a team of six, the researchers measured their pain threshold by how long they could tolerate an inflated blood pressure cuff on the arm.

Exercise increased both groups' ability to tolerate pain, but the difference was significantly more pronounced among the team rowers.

This, they said, was a measure of an increased endorphin release.

As well as potentially improving performance in sport, the researchers speculated that this endorphin release may be the mechanism that underpins the sense of communal belonging that emerges from activities such as religious rituals, dancing or laughing.

"The results suggest that endorphin release is significantly greater in group training than in individual training even when power output, or physical exertion, remains constant," said lead author Emma Cohen.

"The exact features of group activity that generate this effect are unknown, but this study contributes to a growing body of evidence suggesting that synchronised, coordinated physical activity may be responsible."

Carole Seheult, a sport and exercise psychologist from the British Psychological Society, said the findings were entirely credible.

"Rowing is a sport which requires real team work and endorphins could well foster that process.

"But more generally we know from experience that exercising in groups is good for people at many levels, it's motivational, it's social. Groups sessions really do work."

Increase Your Metabolism to Lose Weight

Saturday, December 26th, 2009

boost-your-metabolismDo you want to know how you can slim down and burn calories in your sleep?  By raising your metabolism, you can turn your body into a fat burning furnace.

how to blow your metabolism up through the roof:

The body’s metabolism turns the food you eat into fuel for your body. The higher your metabolism is, the quicker you will burn the calories you eat.  And the lower it is, the fatter you’ll get.  Let’s find out how to increase your metabolism so you can shed those pounds.

Your body gets energy from the calories you eat.  Your cells–each and every one of them–get its energy from the foods you eat.  These calories are used to keep every part of your body running.  The more active you are, the faster you will burn through the calories you eat, and the faster you’ll lose weight.

To lose weight you will need to raise your metabolism.  Specifically, we want to raise your resting metabolism.  When you do this, you won’t even have to work out to burn up all those calories.

You’ll have to modify your lifestyle.  You’ll be eating better and working out.  Once you do both of these, you’ll see those pounds fall away and never haunt you again.

Food:  It probably won’t be easy to get in the habit of getting different foods.  But you won’t necessarily change your whole diet around.  Start by changing the portions of what you already eat.  Then you can start finding foods to eat to lose weight. Most Americans eat too much fat and not enough carbohydrates, so try to balance that out.

Hit the Gym:  You need two types of exercise: aerobic and resistance training. Aerobic exercises including jogging and biking are great ways to actively burn calories.  Weight training is for more that just bodybuilder.  After each workout, your muscles will eat up all those calories you eat to rebuild and repair themselves.

Follow both of these and your metabolism will skyrocket and your weight will drop significantly.

Molecules and synapses cement memories, say scientists

Thursday, December 24th, 2009

BBC News

US scientists believe they have uncovered one of the mechanisms that enables the brain to form memories.

neurons
Neurons are core components of the brain, transmitting and processing data

Synapses - where brain cells connect with each other - have long been known to be the key site of information exchange and storage in the brain.

But researchers say they have now learnt how molecules at the site of the synapse behave to cement a memory.

It is hoped the research, published in Neuron, could aid the development of drugs for diseases like Alzheimer's.

The deteriorating health of the synapses is increasingly thought to be a feature of Alzheimer's, a disease in which short-term memory suffers before long-term recollections are affected.

A strong synapse is needed for cementing a memory, and this process involves making new proteins. But how exactly the body controls this process has not been clear.

Now scientists at the University of California Santa Barbara say their laboratory work on rats shows the production of proteins needed to cement memories can only happen when the RNA - the collection of molecules that take genetic messages from the nucleus to the rest of the cell - is switched on.

Until it is required, the RNA is paralysed by a "silencing" molecule - which itself contains proteins.

When an external signal comes in - for example when one sees something interesting or has an unusual experience - the silencing molecule fragments and the RNA is released.

Kenneth Kosik of the university's neuroscience research institute said: "One reason why this is interesting is that scientists have been perplexed for some time as to why, when synapses are strengthened, you have the degradation of proteins going on side by side with the synthesis of new proteins.

"So we have now resolved this paradox. We show that protein degradation and synthesis go hand in hand. The degradation permits the synthesis."

Identifying the proteins the brain needs in order to cement the memory could ultimately have benefits for those suffering from memory disorders.

Rebecca Wood, head of the Alzheimer's Research Trust, said: "Scientists say they have studied nerve cells in the laboratory and learnt more about how specific proteins may have a role in areas of the brain that transmit messages and help us store memories.

"This interesting development could give a greater understanding of the memory loss experienced by people with Alzheimer's and other forms of dementia and lead to new treatments."

The most recent projections suggest 115 million people across the globe will suffer from dementia by 2050.

Julie Williams, professor of psychological medicine at Cardiff University, said: "Our increasing understanding of genetic risk factors in Alzheimer's is pointing to the synapses so any new study in this area is welcome.

"Alzheimer's is a complicated disease and it is early days, but the health of synapses and their activity levels is becoming an important and interesting focus of research."

Obesity Worse Than We Thought

Thursday, December 24th, 2009

FTYou don’t have to be a doctor to know obesity is bad for you; heart disease, cancer, diabetes, stroke, high blood pressure, all worsened by being obese.

Now experts think cardiovascular mortality from obesity could be a lot higher than previously thought.

Speculating in the British Medical Journal, researchers claim more respiratory disease and lung cancer deaths could be influenced by obesity than typically reported.

Here’s why. Severe illnesses, like lung cancer, usually cause weight loss, so at the time of death the person is not obese, which creates inaccuracies in the statistics.

Special Hormone Turns off Human’s Need to Booze

Thursday, December 24th, 2009

BRI’d think hormones would lead you to drink, and probably coax you into doing other things at the bar too, like lame pickup lines.

But researchers believe lowering ghrelin, a hormone produced in the stomach, may halt the desire to drink alcohol, and over eat.

Ghrelin is also known to promote appetite.

For the study, appearing in The Proceedings of the National Academy of Sciences of the USA, found mice pumped full of ghrelin were more likely to consume alcohol, when given the choice between water and hooch.

On the flipside, mice injected with an antagonist to ghrelin resisted alcohol. Scientists believe futzing with ghrelin could be used to treat alcohol addiction.

Cervical cancer link to early sex

Monday, December 21st, 2009
BBC News

Having sex at an early age has been linked with double the risk of developing cervical cancer.

HPV
Sexually transmitted infection, HPV, causes most cases of cervical cancer

An investigation into why poorer women have a higher risk of the disease found they tended to have sex around four years earlier than more affluent women.

It had been thought that the disparity was due to low screening uptake in poorer areas, but the study found this was not the most important factor.

The latest findings are published in the British Journal of Cancer.

Although the difference in cervical cancer incidence between rich and poor - across the world - had been noted for many years, it was not clear why this is the case.

Especially as rates of infection with human papillomavirus (HPV) - the sexually transmitted infection linked with the vast majority of cervical cancers - seemed to be similar across all groups.

The study, by the International Agency for Research on Cancer, of nearly 20,000 women, confirmed that the higher rates of cervical cancer were not linked to higher HPV levels.

But what it did reveal is that the two-fold increased risk was largely explained by women from poorer backgrounds starting to have sex at a younger age.

The age at which a woman had her first baby was also an important factor.

Screening was found to have some effect on the level of risk.

But the number of sexual partners a woman has and smoking did not account for any of the difference.

Lag time

Study leader, Dr Silvia Franceschi, said the findings were not restricted to adolescence and the risk of cervical cancer was also higher in women who had their first sexual intercourse at 20 rather than 25 years.

"In our study, poorer women had become sexually active on average four years earlier.

"So they may have also been infected with HPV earlier, giving the virus more time to produce the long sequence of events that are needed for cancer development."

Dr Lesley Walker, director of cancer information at Cancer Research UK, said the study raised some interesting questions.

"Although women can be infected by HPV at any age, infections at a very young age may be especially dangerous as they have more time to cause damage that eventually leads to cancer.

"Importantly, the results back up the need for the HPV vaccination to be given in schools at an age before they start having sex, especially among girls in deprived areas."

Heart attack risk ‘raised by bottling-up anger’

Friday, December 18th, 2009
BBC News

Men who do not openly express their anger if they are unfairly treated at work double their risk of a heart attack, Swedish research suggests.

Upset man
Nearly 50 of the studied men died from a heart attack or heart disease

The researchers looked at 2,755 male employees in Stockholm who had not had a heart attack when the study began.

They were asked about how they coped with conflict at work, either with superiors or colleagues.

The researchers say their study shows a strong relationship between pent-up anger and heart disease.

Writing in the Journal of Epidemiology and Community Health, the researchers called the various strategies for keeping things bottled up, covert coping.

The men were asked what methods they adopted: whether they dealt with things head-on, whether they let things pass without saying anything, walked away from conflict, developed symptoms like headache or stomach ache or got into a bad temper at home.

Hospital registers

They were checked for smoking, drinking, physical activity, education, diabetes, job demands and their freedom to take decisions.

Their blood pressure, body mass index and cholesterol levels were measured and they were aged 41 on average at the start of the study between 1992 and 1995.

Details of whether any of the men subsequently had a heart attack or died as a result of heart disease in the period up to 2003 were gathered from national registers of hospital treatment and deaths.

Up to 2003, 47 of the 2,755 men had a heart attack or died from heart disease.

The men who coped by sometimes or often walking away or who often let things pass without saying anything, had double the risk of a heart attack or dying from serious heart disease compared to men who challenged and dealt with the situation head-on.

Developing a headache or stomach ache or getting into a bad temper at home, did not increase the risk of heart attack or heart disease.

The researchers believe that anger can produce physiological tensions if it is not released and that these lead to increases in blood pressure which eventually damage the cardiovascular system.

'Conflict situations'

Dr Constanze Leineweber, who led the study from the Stress Research Institute in Stockholm, said: "There has been research before pointing in this direction but the surprise is that the association between pent-up anger and heart disease was such a strong one.

"I think men can't help how they behave in conflict situations - it's not something they think about, it's just how they react instinctively.

"If you are smoking and don't exercise you would be much more conscious of the risk."

Judy O'Sullivan, senior cardiac nurse for the British Heart Foundation, said: "Stress itself is not a risk factor for heart and circulatory disease, but some people's responses to stress, such as smoking or overeating, can increase your risk.

"We all find different things stressful and symptoms of stress can vary, but the important thing is that we need to find ways of coping with it in our lives in a positive way, whether at work or home."
