It is Easy to Reduce Weight at Home
Obesity has become one of the major health problems all over the world. The problem has given rise to quick-fix slimming centres everywhere. Most of these centres lure the people by offering miracle solutions with medicines, super fat free diet, and new exercise gadgets. Most of their methods prove unscientific and dangerous. Their side effects can actually ruin your health instead of making you slim and healthy. Moreover after a short period you will again start gaining weight. The exercise which can be done at home is the best method and you can learn it easily. But never jump upon any exercise schedule with full force. Take it easy. Start with only a ten minutes schedule everyday (home exercise schedule) and then increase the time of the activities gradually. You can incorporate some outdoor activities in your exercise schedule.
1. Running at Slow Pace
Running is a good exercise for weight-reduction. You can go to a nearby park and enjoy running. You can burn more than 100 calories just in fifteen minutes.
2. Running at a Place
If you don’t want to go out you can get the same benefit at your home by running at a place. You can do it in any small corner of your house. You can also jump at a place to get the same benefit.
3. Lie Down and Cycle
It is the best exercise for your stomach and thighs. You can do this exercise by lying on bed and moving your legs like you are cycling.
4. Moving Arms Up and Down
Stand at a place. Move your arms to upward direction simultaneously moving your body up with the help of feet fingers. Then bring your arms down along with your body.
5. Body Movement to Different Directions
You can do this exercise by moving any part of your body specially arms and legs to different directions as seems easy to you. Never make any strenuous movements. Such simple movements give exercise to almost all the parts of your body.
6. Do Household Work
Doing the household work as much as you can will prove one of the best weight control method. You not only get a good exercise but also get a satisfaction of completing those works which needed your attention.
7. Use Stairs
For going up try to use stairs instead of escalators or elevators. Stairs may take more time but the exercise your body get will be immensely beneficial
8. Walk to Your Working Place
Try to walk to your working place. If it is very far try to park your vehicle somewhat away from your working place so that you may get opportunity to walk. Walk as much as possible. It is the easiest way to burn extra calories and get stamina. Brisk walking burns around 180 calories in half an hour.
9. Enjoy the Fun of Cycling
Instead of two-wheelers we need to popularize cycling again for shopping or covering short distances. It is a wonderful cardio activity. It burns between 100 to 200 calories just in fifteen minutes. If you hesitate to go out on cycle keep a cycling machine at home. It is equally beneficial. But you will surely miss fun of outdoor.
10. Start Lifting Weights
Young men love to lift weights and they mostly do it to build muscles. Just after six months training they find that they are looking more beautiful and healthy. But aged and physical weak persons must consult a physician before opting for hard exercise schedule. And most of the ladies don’t like any muscle building exercise.
This simple exercise schedule will actually change your life style giving you a fit and healthy body as well as a long life.

Obesity Takes Years Off Your Life
It's similar to smoking when it comes to effect on longevity, researchers note
TUESDAY, March 17 (HealthDay News) -- Being obese can shorten your life, a new study shows.
"Moderate obesity typically shortens life span by about three years," said researcher Gary Whitlock, from the Clinical Trial Service Unit at the University of Oxford in the United Kingdom. "By moderate obesity, I mean weighing about a third more than is ideal, which for most people would mean being about 50 or 60 pounds overweight."
More than one in three middle-aged Americans are now in this category, Whitlock said. "By contrast, weighing twice your ideal weight -- say, an extra 150 pounds -- shortens life span by about 10 years," he added.
This obesity level is still not common, but it equals the known 10-year reduction in life span caused by smoking. "So, smoking is about as dangerous as being severely obese, and about three times as dangerous as being moderately obese," he said.
The report is published in the March 18 online edition of The Lancet.
For the study, Whitlock and other members of the Prospective Studies Collaboration collected data on 894,576 men and women who participated in 57 studies. The people in these studies came primarily from western Europe and North America. Their average body-mass index (BMI) was 25.
BMI is a calculation that expresses a relationship between height and weight. People are considered underweight if their BMI is less than 18.5, normal weight when the BMI is between 18.5 and 24.9, overweight when BMI is between 25 and 29.9, and obese when BMI is 30 or more, according to the U.S. National Heart, Lung, and Blood Institute.
The researchers found that men and women whose BMI was between 22.5 and 25 lived the longest. For a person 5 feet 7 inches tall, his or her optimum weight would be about 154 pounds, they noted.
For those with a BMI over 25, every 10 to 12 pound increase translated to about a 30 percent increased risk of dying. In addition, there was a 40 percent increase in the risk for heart disease, stroke and other vascular disease, a 60 percent to 120 percent increased risk of diabetes, liver disease or kidney disease, a 10 percent increased risk of cancer, and a 20 percent increased risk for lung disease, the researchers reported.
"Obesity causes kidney disease, liver disease and several types of cancer, but the most common way it kills is by causing stroke and, most importantly, heart disease. Obesity causes heart disease by pushing up blood pressure, by interfering with blood cholesterol levels, and by bringing on diabetes," Whitlock said.
People who are moderately obese with a BMI in the 30 to 35 range reduced their life span by two and four years. For those who are severely obese with BMIs between 40 and 45, their life span was reduced by eight to 10 years. That's comparable to the effects of smoking, Whitlock said.
In fact, people whose weight was below normal also died earlier, due mainly to smoking-related diseases, the researchers noted.
"If you are obese and smoke, then, above all else, quit smoking," Whitlock said. "If you are obese and don't smoke, then don't start, and do what you can to avoid further weight gain. By avoiding further weight gain, you may well live a few years longer than you otherwise would do. By quitting smoking, a smoker can expect to gain several extra years of life -- about as many as a severely obese person might gain by shedding half of his or her body weight."
Dr. David L. Katz, director of the Prevention Research Center at Yale University School of Medicine, said this study confirms that the obesity epidemic is "the clear and present danger many of us knew it to be."
The association between BMI and mortality has been challenged in the scientific community, due in part to uncertainty about weight estimates and debate about measurement methods. "Here we have an emphatic reaffirmation of the fundamental issue: Overweight and obesity take years from life," Katz said.
"We know that, in many ways, BMI is a crude measure of the health risks associated with obesity, since not all excess body fat is created equal," he said. "Weight gained around the middle tends to be most dangerous, so for those subject to this pattern, risks may indeed be higher than this study suggests. For those with lower body weight gain, risks may be lower."
A study published in the Nov. 13 issue of the New England Journal of Medicine also found that where weight is centered is a risk factor. Men with the largest waist circumference had more than double the risk of death, and women with the largest waist circumference increased their risk of death by 78 percent.

If your workout is not working for you !
Your time is valuable, and for each precious moment you put into your workouts, you want to ensure you get the best possible return on your investment. So, are you getting the results you want? If your body isn't as lean or toned as you'd like, it may be that you're committing some key training mistakes, which can sabotage the efforts of even veteran exercisers.
Of course, you probably know the more obvious mistakes to avoid. For instance, skipping your warm-up may cause you to fatigue early, preventing you from realizing your potential. Furthermore, leaning on the stair climber or elliptical trainer may allow you to stay on longer, but it drastically reduces the challenge to your lower body as well as the number of calories you burn. But what about the less obvious errors you may be making? Here, we'll discuss some of the more subtle -- yet no less serious -- faux pas of fitness and the strength-training exercises most frequently flubbed, and show you how they can be fixed with nearly effortless corrections.
THE TEN FAUX PAS OF FITNESS
People make small but costly mistakes when exercising every day, and one tiny change can have a huge impact on their results, says Los Angeles–based trainer Ken Alan, a spokesman for the American Council on Exercise. Thanks to Alan and the panel of training experts who weighed in on these faux pas and fixes, you'll error-proof your exercise and see tremendous payoffs, and the time you invest in your workouts will be smart and well-spent. We begin with five errors often made in your approach to exercise, then we'll take a look at five moves frequently flubbed.
THE APPROACH
1. The faux pas Getting married to your strength routine
The facts If you do the same routine over and over, your muscles will simply adapt; you're likely to hit a plateau because each exercise stimulates only a limited number of muscle fibers. However, if you challenge your muscles from a variety of angles by adding or alternating moves periodically, you'll get significantly more fibers into the act and develop more tone and strength.
The fix For each muscle group, learn an additional 2 or 3 exercises, trying new angles and equipment. (If you can't get instruction from a trainer, there are plenty of books and videos organized by routine for each body part.) For instance, if you usually do the dumbbell chest press on a flat bench, try it at an incline. If you normally use the chest-press machine, try the dumbbell chest press or the bench press with a barbell. Expand your repertoire enough so that you can change your entire routine every 6–8 weeks.
2. The faux pas Performing your reps too quickly
The facts If you zoom through your repetitions when strength training, you'll be using momentum instead of muscle power. You won't get the same stimulus for muscle building, and you won't burn as many calories. You'll also be more susceptible to training injuries such as torn muscles or connective tissue.
The fix Take 6 seconds to perform each repetition: 2 seconds to lift the weight and 4 seconds to lower it. (Since you have gravity to help you lower the weight, you need to slow down even more on this phase in order to give your muscles a sufficient challenge.) Our experts agree that slowing down is the single most significant change you can make to get better results from strength training.
3. The faux pas Exercising too hard, too often
The facts If you don't rest enough between hard cardio or strength workouts, you'll stop making progress and may even lose some of the fitness you've gained. You're also likely to burn out on exercise.
The fix To keep your muscles fresh and your motivation high, alternate shorter, tougher cardio workouts (for instance, 20 minutes) with longer, easier days (40–60 minutes). Don't go all-out more than twice a week. Keep in mind that the more intensely you train, the more time your body needs to recover. It's a good idea to do a couple of tough workouts and take 1 day completely off each week. On the strength-training front, take at least 1 day off between sessions that work the same muscle group.

Having Fat Friends May Make You Fat as Well: Study
Written by Sapna Mhatre
Friday, 25 July 2008
FRIDAY, July 25, (News Locale) - The adage "You are known by the company you keep" seems to apply to obesity and overweight as well. Researchers have found that people who have fat friends are more likely to put ion some unwanted pounds as compared to people who have leaner friends.
The study by researchers from the University of Warwick, Dartmouth College, and the University of Leuven analyzed data on 27,000 people from across Europe. The findings suggest if you have overweight friends it is acceptable if you are fat as well.
"Rising obesity needs to be thought of as a sociological phenomenon not a physiological one," said co-researcher Professor Andrew Oswald at the University of Warwick.
The researchers feel people are subconsciously influenced by the weight of people around them. In what they called "imitative obesity," the researchers said hefty people tended to have heavier friends as compared to people having normal weight.
The findings of this international study are due to be presented at the National Bureau of Economic Research conference in Cambridge, Massachusetts.
Obesity is a dangerous condition which is linked to the so-called lifestyle diseases like type 2 diabetes mellitus, hypertension, obstructive sleep apnea, nonalcoholic steatohepatitis, heart disease, poor self-esteem, and a lower health-related quality of life.
Sedentary lifestyle practices coupled with a shift in diet to junk foods are the main reason behind this explosion of overweight or obese populations. The World Health Organization has declared obesity as a global epidemic having major health implications in 1997. It estimated that some 2 billion people worldwide are obese or overweight.
If the above study is true, then consumers may derive some benefit by keeping company with slim friends!

Blame your hubby for your being fat!
Thursday, 24 July , 2008, 02:49
Melbourne: Tried everything but can’t seem to get rid of your post-marriage love handles? Well, don’t question your determination for the failed plan, for the real culprit behind all weight worries is your hubby.
Yes, you heard it right. According to health experts, a husband is more of a hindrance than help in a wife's battle with the bulge.
"For some women, marriage definitely can be fattening," the Courier Mail quoted Dr Brian Steadman, a leading British authority on nutrition, as saying.
"It's hard enough for them to stick to good eating habits when they're single, but they can find it impossible after they're married.
"For a start, they've got to prepare food for two people, and it gets worse when children come along. Suddenly, she is constantly thinking about food - buying it, cooking it, fixing snacks and meals at different times of the day.

“And if the husband doesn't need to diet, then with all the best intentions in the world, the poor woman is going to find it very tough preparing big wholesome meals for the family and low-calorie snacks for herself,” he added.
Dr Richard B Stuart, an American authority on slimming and nutrition, and former psychological director of Weight Watchers International, the author of Act Thin, Stay Thin, agrees.
"If a woman can't stay on a diet, it could easily be her husband's fault," he said.
"In fact, a husband might subconsciously be encouraging his wife to remain fat, and make it harder for her to lose weight,” he added.
Dr B Stuart has given some reasons as to why this could be so: if he feels in any way insecure in his relationship, then he reasons that a plump wife is less likely to leave him or make other men jealous, if he has a low sex drive then having a fat wife is a very good excuse for lack of interest or potency.
If he's the kind who isn't prepared to put a lot of effort into the marriage, then it will be much easier for him to keep her "fat" than "happy", Dr B Stuart said.
If his wife is a failure as a dieter, it "allows" him to have his workaholic schedule or an affair and there are many other ways that a husband, perhaps unwittingly, can hinder his wife's ambitions to keep her weight down, the health expert added.

‘Excessive weight loss can affect women’s ability to conceive’
New Delhi, July 15: If you are a woman obsessed with having rail-thin figures like fashion models and cine celebrities, take a pause, as it can cost you the ability to become a mother.
Experts warn that gymming and dieting more than one’s capacity in a bid to have a size-zero figure can affect the menstrual cycle among females up to the extent of complete loss of periods and ability to become pregnant.
“Possibilities of premature delivery, birth of low-weight babies and malnourishment are much prevalent in such women, even if they conceive after medical treatment,” Jyoti Sharma, gynaecologist, Umkal hospital said.
“Women doing extra gymming and dieting can suffer from Amenoria (Abnormal Menstruation) and loss of libido due to suppression of Follicle Stimulating Hormone (FSH) and other secondary sex hormones in brain,” says gynaecologist and infertility specialist Dr Shibani Sachdev Gaur.
The medics also warn against the pills taken by several women for sudden weight reduction. “Most of the pills, even in the guise of herbal formulations, contain certain amount of oestrogen similar to contraceptive pills which restrict pregnancy”.
In acute cases, ovaries stop producing eggs that means complete loss of one’s ability to conceive,” adds Dr Gaur citing the example of one of her patients who was losing weight to become an air hostess.
Gaur said, “even though her menstrual cycle resumed, the lady is still undergoing treatment for irregular periods for more than seven years”.
“Too much physical work can suppress the Hypothelemo pituitary axis responsible for the release of sex hormones.
When the hormones are unable to send signal to ovaries, the release of oestrogen get disturbed,” she reasons.
Beside Amenoria, another threat for skin-slim obsessed girls is anorexia, which leads to osteoporosis.
“Now-a-days, teens are getting bones like 80-year old.
Deficiency of nutrition due to restricted diet weakens bones to such extent that it cause fracture and death”, Dr Gaur says.
“Anorexia Nervosa which is caused due to abnormal intake of food affects all organs including bones, brains and glands, agrees Dr Jyoti who suggests Liposuction -- a less harmful method of weight loss -- but prefers only Yoga and moderate exercises.
Fashion models, however, disagree that being thin and super slim are in for the glamour world.
“It’s all myth that models are anorexic. What modelling requires is that one should be toned. It’s always good to be healthy and fit,” says model Anousha.
Quick-fix artificial methods of weight loss are also not preferable for models.
“Fitness depends upon one’s body type- some people are genetically blessed, some can remain fit by a little bit of swimming and some people have to go to gym,” she says.

Exercise increases protein that may curb appetite
By Megan Rauscher
NEW YORK (Reuters Health) - In a small study of overweight and obese adults, 3 months of aerobic exercise, with no change in diet, led to a significant decrease in body fat and a spontaneous drop in calorie intake. The amount of weight loss and the reduction in calorie intake were directly related to blood levels of a protein called brain-derived neurotrophic factor (BDNF).
"The reduction in calorie intake could be related to the effect of BDNF," Dr. Henry Anhalt of the Animas Corporation, West Chester, Pennsylvania told the Endocrine Society's annual meeting in San Francisco.
"It is possible that the increases in this compound in fact suppress appetite; however, this was not directly tested," added Anhalt, who moderated a press conference where the study was reported.
In the study, Dr. A. Veronica Araya and colleagues from the University of Chile Clinical Hospital in Santiago evaluated blood levels of BDNF before and after 3 months of aerobic exercise in 15 overweight or obese men and women. The 7 men and 8 women, ages 26 to 51 years, exercised on a treadmill and bicycle.
At the end of the 3-month exercise period, study subjects showed a significant drop in body weight, waist size, and percentage body fat.
They also experienced a fall in blood pressure and spontaneously began consuming fewer calories each day. At the same time that these effects were occurring, blood levels of BDNF rose markedly.
In a statement issued through the Endocrine Society, Araya said: "It is important to clarify the factors involved in the response to different weight loss therapies, because we could find a marker to predict response to the intervention."

Viagra rival being developed
By Bonnie Malkin
A "wonder pill" that could increase sex drive in women and men and outsell Viagra is being developed by scientists.
The medication, which has the potential to boost fertility rates, is also believed to help aid weight loss.
The pill, which is being developed by the Medical Research Council’s Human Reproductive Sciences unit in Edinburgh, uses a hormone to release the chemical Type 2 gonadtropin, which drives the reproductive system.
It is expected to outperform Viagra because it will increase the brain’s desire for sex, wheras Viagra only boosts the body’s sexual capability.
