Are you tired of exercises that hurt your body? If you’re looking to an alternative for jarring exercises that damage your joints, you should consider low impact exercise. You don’t need to sacrifice your health for a great workout. Find out everything you should know about losing weight with low impact exercise.
The Benefits of Low Impact Exercise
There are hundreds of different exercise programs and workouts readily available. However, some of those exercises aren’t healthy for you. They put your body and your health at risk.
Activities like running can improve your cardio and help you lose weight. Unfortunately, such activities are brutal on your joints. If you run regularly, you could destroy the cartilage in your knees.
Tough exercise regimens put you at a greater risk for surgeries, like hip replacements. After years of brutal workouts, your body wears down and needs medical attention.
When you use low impact exercise in your workout routine, you limit the damage. Your joints remain healthy and intact. As you age, you are less likely to require surgery. Additionally, you are less likely to injure yourself during a workout.
Low Impact Exercises that Help You Lose Weight
When people think of low impact exercises, they often think of workouts that are ineffective. However, this is far from the truth. Low impact exercises can be just as effective as high impact ones.
When it comes to weight loss, burning calories is what matters. There are many great low impact exercises that burn high amounts of calories. Here are a few:
Swimming is a highly effective workout. More importantly, it’s also easy on your body. There is no gravity weighing you down and putting pressure on your joints. Instead, the water holds you up.
Swimming can burn hundreds of calories in a short time. If you have proper technique, you can maximize your calorie burn. Before you get started, you might consider taking lessons or watching a tutorial. You can get down the technique and start losing weight.
People often think of yoga as a great way to relax. Although it is the perfect activity for relieving stress, it’s also great for weight loss.
There are many different types of yoga. The type of yoga class you take can dictate the amount of calories you burn. For example, hot yoga is fast-paced and occurs in a hot environment. You sweat and get your heart rate up. As a result, you lose weight quickly.
In general, yoga is very easy on your joints. The flexibility that comes with yoga decreases your chances of injury. Overall, yoga is an effective way to improve your health while you lose weight.
There are many different ways to cycle. However, all of them provide a low impact exercise that helps you lose weight. The workout works your legs and your core, maximizing your calorie consumption.
If you want a competitive workout, you can try a cycling class in a local gym. But if you’re looking for something more relaxing, you can go for a bike ride around your neighborhood. Either way, you’ll burn calories.
Chaz Bono looked half his former size as he stepped out in West Hollywood, California, on Wednesday.
Chaz Bono, 44, started his weight loss journey in 2011 after starring on Dancing With The Stars.
At the time, Chaz Bono weighed a staggering 253 lbs despite being only 5 ft 5.
It was not until November the following year, however that Chaz Bono really committed to losing weight in and just nine months later had dropped over 70 lbs – ten more pounds than his goal weight.
Now it appears Chaz Bono may have lost even more weight showing off his defined arms and much flatter stomach as he arrived for class at Anthony Meindl’s actors workshop.
Chaz Bono did reveal one of his secrets to weight loss as he went to feed his meter – a bottle of water made to taste better with, no doubt low calorie, orange flavoring.
His other secret has been dedicating himself to diet and exercise as well as using recently FDA approved obesity drug Qsymia under the supervision of a doctor.
Chaz Bono sought medical help as he required doctors to work out a way for him to lose weight while continuing to take male hormones following his gender reassignment surgery.
He was already over the moon with his weight loss back in May, when he had dropped 60 lbs.
Chaz Bono told People losing the weight had changed his life and his health.
“I just have a lot more confidence, and that feels really cool. I really like what I see in the mirror.
“Physically, my body feels just so much better I’m in a lot less discomfort when I exercise and am doing physical stuff. All of my numbers are all normal now, which is great – my blood pressure, my cholesterol.”
A postage stamp-sized plastic square sewn onto the tongue helps losing weight fast.
Two women have tried out the “miracle” patch – Marlene Beltran, 20, and Lysander Lanuza, 27, – who both admitted to being unable to control their food cravings, put the tongue patch to the test in an ABC News segment.
Despite the pain and discomfort that came with it, the women were pleased with the results, with Lysander Lanuza losing an incredible 23 lbs and Marlene dropping 18 lbs in just 30 days.
Launched in 2009 by Beverly Hills plastic surgeon Nikolas Chugay, the patch is secured to the tongue with six stitches in a $2,000 procedure that takes just ten minutes.
The sutures make consuming solid food so painful that users are forced to resort to a restrictive 800 calorie liquid-only diet developed by Dr. Nikolas Chugay.
Lysander Lanuza, who weighed 200 lbs before the surgery and whose motivation is a trip to Hawaii in a month’s time, giggles after her surgery is finished, and mumbles: “I can’t feel my tongue.”
The numbness continues until the anesthetic wears off, at which point she finds it very painful to consume anything other than liquid.
Indeed, Lysander Lanuza learns the hard way that the patch is effective when she caves in at a movie theater and indulges in a single piece of popcorn.
“It hurt,” she says.
“I’m like, Christ it does work, I can’t eat!”
The tongue patch diet was launched in 2009 by Beverly Hills plastic surgeon Nikolas Chugay
Marlene Beltran, who started out at 169 lbs, manages to resist her cravings for fast food, but she experiences grouchiness whenever her family sits down to dinner and she is forced to stay in a different room.
These are just some of the side effects of the controversial procedure, which is yet to be FDA-approved.
According to a study submitted by Dr. Nikolas Chugay’s son and partner Paul, their patients lose an average of 18 lbs in 30 days, and they keep the weight off for eight months.
But the American Academy of Cosmetic Surgery has yet to publish the research, because it was found to have “insufficient data”.
Indeed, while Dr. Nikolas Chugay insists he has never met with any skepticism, weight loss expert Dr. Robert Huizenga told the news website he is unconvinced of the patch’s effectiveness, especially over time.
“This is so primitive an approach,” the physician, who has appeared on the Biggest Loser, says.
“You could hire somebody to hold a gun next to your head and threaten to shoot you every time you eat.
“The idea that you put this patch in and every time you take one morsel of solid food, you get this stabbing pain, who the heck know what the long-term consequences of that are.”
He also adds that many studies suggest that those who lose weight rapidly tend to gain it all back, and more.
Nevertheless, throughout the 30 days, both Marlene Beltran and Lysander Lanuza instantly and happily notice a difference as the pounds begin to drop.
“I’m getting a lot more attention from guys, which is nice,” Marlene Beltran says on day 22.
“It’s attention I’m not really used to.”
After 30 days are up, the women have their patches removed and they step on the scales to see the results.
Lysander Lanuza has dropped 23 lbs, just in time for her Hawaii vacation, and Marlene Beltran has lost an incredible 18 lbs, and is finally able to squeeze into her skinny jeans for the first time in four years.
“I’m excited now to see how things turn out,” Marlene Beltran says as she grins at her reflection in the mirror.
Former actor Miki Ryosuke claims to have lost 28 lbs and 5 inches from his waist in seven weeks by following his Long Breath Diet.
Miki Ryosuke, 55, claims that followers of the diet just have to spend two minutes a day concentrating on taking long breaths and then exhaling aggressively.
The dieting guru says that he invented the diet by mistake while practicing breathing techniques in an attempt to reduce his back pain, Oddity Central reports.
While he was practicing the breathing techniques, Miki Ryosuke noticed that he was losing weight.
As a result of the discovery, he drew up the Long Breath Diet which involves the dieter taking a specific position before inhaling for three seconds and then exhaling powerfully for seven seconds.
Miki Ryosuke claims that people who practice this breathing technique for two to five minutes a day will see rapid benefits.
Miki Ryosuke claims to have lost 28 lbs and 5 inches from his waist in seven weeks by following his Long Breath Diet
Oddity Central reports that there are two ways of practicing the diet.
The first involves tensing the buttocks while standing with one foot in front of the body and placing most of the body’s weight on the back foot.
In this position, the dieter is encouraged to inhale for three seconds while lifting their arms above their head.
They are then told to breathe out while tensing all of their muscles for seven seconds.
The second way of practicing the technique involves the dieter standing upright while tightening their buttocks and placing one hand on their stomach, and the other on the bottom of their back.
They are then told to inhale for three seconds before breathing out for seven seconds, all of the time holding in their stomach.
Jill Johnson, creator of the Oxycise, another weight loss programme based on breathing, told Oddity Central: “Fat is made up of oxygen, carbon, and hydrogen. When the oxygen we breathe reaches these fat molecules, it breaks them down into carbon dioxide and water.
“The blood then picks up the carbon dioxide – a waste product of our bodies – and returns it to the lungs to be exhaled. Therefore the more oxygen our bodies use, the more fat we will burn.”
The Long Breath Diet is believed to increase a dieter’s muscle strength and to boost their metabolism by increasing their blood oxygen levels.
However, most experts believe that practicing it for just two minutes a day is not sufficient to see any significant weight loss.
Chaz Bono looked much leaner touching down in New Orleans over the weekend as he is now down a total of 60 lbs.
Chaz Bono, 44, is still slowly losing weight as he told People magazine last week.

The only child of star Cher still takes dance classes and has added martial arts training to his exercise regime.
He has transformed his diet too, saying: “I’ve just changed the way I eat. Diets don’t work. You just have to change what you eat, and I have.”
Chaz Bono initially used Freshology delivered-meal but now prepares food himself, saying: “I cook a lot of different stuff.
“I really avoid grains and starches, so meats and vegetables and fruits are my diet. I make them all different ways to keep it interesting.”
Chaz Bono is thought to be still single after calling off his engagement with fiancée, Jennifer Elia, after 12 years together in December 2011.

Keira Krausz, Nutrisystem’s Chief Marketing Officer, said: “We are thrilled to be helping and working with Melissa. She mirrors our values and will resonate with our customers as authentic.
“Moving forward, you’ll see us have an appropriate mix of inspiring celebrities and real life customers who have also enjoyed success.
“We think dieters are savvier than ever and really appreciate someone who – above all else – is relatable.”
Speaking recently about her post-baby body, Melissa Joan Hart said that looking after Tucker, as well as her two older sons,7-year-old Mason and 5-year-old Braydon, helps her stay active.
The actress said: “I know a lot of people with newborn babies that stay at home with the baby. Maybe I’m a little selfish but I’m like, <<I want to watch my son at hockey>>, so I bundle up the baby and bring him in a car seat and bring him with me.
“I go through the extra effort to be with the older ones too!”
Nutrisystem is delivery service featuring over 100 meal options providing an average of 1,250 calories per day for women, and 1,500 calories per day for men.
Those following the plan can expect to lose around 1 to 2lbs per week. Previous celebrity spokespersons for Nutrisystem have included Janet Jackson and Marie Osmond.
In a new episode of reality show Kourtney And Kim Take Miami, Kourtney Kardashian’s boyfriend Scott Disick is seen admonishing the new mother for not losing weight quickly enough, calling her my “piece of machinery”.
Scott Disick told Kourtney Kardashian: “Last time around you tried to watch what you were eating, after you had Mason… at least you were losing weight.”
“You are so crazy. I’m trying to do it the healthy way,” she replied.
But Scott Disick admonished her: “Just do it faster. You’re my piece of machinery!”
Scott Disick then joked that Kourtney Kardashian was a “problem”, reducing her to tears.

Earlier Kourtney Kardashian complained that she was struggling.
“I feel like it’s definitely harder this time to lose the weight,” she said.
Unsympathetic Scott Disick replied: “If I would have fell in love with you a couple of pounds overweight, this would be my ideal weight, but I fell in love with you when you were super skinny.”
He then told the camera: “Right now seems to be probably the heaviest she’s ever been not pregnant.
“When we had Mason I remember her trying to whip herself back into shape pretty quick. This time around it seems like it’s the least of her concerns, and the only thing she thinks about are the kids.
“I just think that she would feel better if she got back into the shape that she feels the most comfortable in.”
And they fell out at the beach when Scott Disick again questioned her about her figure.
“It would be nice if you were in a wild little flossy bikini,” he said.
“It would be nice,” Kourtney Kardashian said before packing up and leaving the beach in a huff.
Anne Hathaway lost a staggering 16 lbs of her already slim frame to take on the role of Fantine in the new movie adaptation of Les Miserables.
In a new interview, Anne Hathaway, 29, has revealed the extents she went to in a bid to shed the pounds.
The actress told Allure magazine that she underwent some “pretty crazy weight stuff” to get in shape for the role, and survived on radishes and hummus alone.
In the interview, completed as Anne Hathaway was shooting Les Miserables, she said: “I’m on day six of detox… this diet makes me break out, so I love that. Nothing like living on hummus and radishes and then be all, <<And I got a pimple. Yeah!>>”

Anne Hathaway added to the magazine that the hardest part was giving up her favorite food, cheese.
She said: “Cheese is amazing… (but) once you’re over the cheese hump, there’s nothing really left.”
As well as losing weight for Les Miserables, Anne hathaway was also under pressure to get into shape to take on the role of Catwoman in The Dark Knight Rises.
In particular, Anne Hathaway described the pressure of squeezing herself into the character’s famous catsuit as a “psychological terrorist”.
Anne Hathaway said: “The Catwoman suit. It was a psychological terrorist. The suit, thoughts of my suit, changing my life so I would fit into that suit … it dominated my year.”
Scientific evidence increasingly points to a far deeper problem that confronts dieters: cutting out calories changes your metabolism and brain, so your body hoards fat and your mind magnifies food cravings into an obsession.
Slimmers have often feared this was somehow true, but now science confirms this cruel fact of nature. New research shows dieting raises levels of hormones that stimulate appetite – and lowers levels of hormones that suppress it.
Meanwhile, brain scans reveal that weight loss makes it harder for us to exercise self-control and resist tempting food. Worse still, the more people diet, the stronger these effects can become, leaving some almost doomed to being overweight as a result of their attempts to become slim.
And as research lays bare the dangers of yo-yoing weight, some experts argue it would be better not to diet at all.
Researchers, including Joseph Proietto, a professor of medicine at the University of Melbourne, have uncovered one of the main possible reasons. Two years ago, his team recruited 50 obese men and women, and coached them through eight weeks of an extreme 500-to-550-calories-a-day diet (a quarter of the normal intake for women).
At the end, the dieters lost an average of 30 lb. Joseph Proietto’s team then spent a year giving them counseling support to stick to healthy eating habits. But during this time, the dieters regained an average of 11 lb. They also reported feeling far hungrier and more preoccupied with food than before losing weight.
As the researchers reported in The New England Journal of Medicine, the volunteers’ hormones were working overtime, making them react as though they were starving and in need of weight-gain. Their levels of an appetite-stimulating hormone, ghrelin, were about 20% higher than at the start of the study. Meanwhile their levels of an appetite suppressing hormone, peptide YY, were unusually low.
Furthermore, levels of leptin, a hormone that suppresses hunger and raises the metabolic rate, also remained lower than expected.
Joseph Proietto describes this effect as “a co-ordinated defense mechanism with multiple components all directed toward making us put on weight”. In other words, the body had launched a backlash against dieting.
The team’s landmark study reinforces a belief among biologists that the human body has been shaped by millennia of evolution to survive long periods of starvation.
Cutting out calories changes your metabolism and brain, so your body hoards fat and your mind magnifies food cravings into an obsession
The human frame contains around ten times more fat-storing cells in relation to its body weight than most animals (polar bears, which have to endure long stretches when prey is unavailable, are similarly fat-rich).
Our calorie-hoarding frames have strong mechanisms to stop weight loss, but weak systems for preventing weight gain. If you manage to lose 10% of your weight, your body thinks there’s an emergency. So it burns less fuel by slowing your metabolism.
The body learns to function on fewer calories, resetting your metabolism. The problem is if you then stop dieting and start eating more again, those extra calories are stored as fat.
This effect kicks in after around eight weeks of dieting – and can last for years. Studies by Columbia University show this metabolic slowdown can mean that just to maintain a stable weight, people must eat around 400 fewer calories a day post-diet than before dieting.
Why would this be so? Muscle samples taken before and after weight loss show that once a person drops weight, the fibres may change to become more fuel-efficient – burning up to a quarter fewer calories during exercise than those of a person at the same weight naturally.
How long this state lasts isn’t known, though some research suggests it might be up to six years.
It’s also thought the brain changes in the way it reacts to food. This wilts our willpower, according to Michael Rosenbaum, a researcher at Columbia University Medical Centre who studies the body’s response to weight loss.
“After you’ve lost weight, there’s an increase in the emotional response to food,” he says, adding that there is also “a decrease in the activity of brain systems that might be more involved in restraint”.
In 2010, Michael Rosenbaum and his colleague, Joy Hirsch, a neuroscientist at Columbia University Medical Centre, scanned the brains of people before and after weight loss while they looked at objects such as grapes, chocolate, broccoli and mobile phones.
After losing weight, the scans showed a greater response in the areas associated with reward and a lower response in those associated with self-control.
And last year, scientists at the Albert Einstein College of Medicine in New York discovered that when starved of food, brain cells actually consume each other. This causes the release of fats, which in turn results in higher levels of a powerful brain chemical that stimulates appetite, the journal Cell Metabolism reports. All bad news for dieters, as going without food could make them even hungrier.
All of this helps to explain why an analysis of 31 long-term clinical studies found that diets don’t work in the long run. Within five years about two-thirds of dieters put back the weight – and more. The researchers from the University of California found that dieting works in the short term, with slimmers losing up to 10% of their weight on any number of diets in the first six months of any regimen. But after this, the weight returns, and often more is added, says their report in the journal American Psychologist.
The analysis concluded that most volunteers would have been better off not dieting. Their weight would be pretty much the same and their bodies would not have wear and tear from yo-yoing.
This backfire effect is worst among teenagers: people who start habitually dieting young tend to be significantly heavier after five years than teens who never dieted. This mix of biology and psychology translates into a sobering reality: once we become overweight, most of us will probably remain that way.
Certainly, we should all be worried about what dieting does to our health. Restricting calories may increase the risk of heart disease, diabetes and cancer, according to a study from 2010 in the journal Psychosomatic Medicine.
Ultimately, of course, we should be more wary of piling on the pounds, than relying on diets to reverse the damage.
You have cut out calories and joined a gym, but are seemingly innocuous things stopping you from losing weight?
Researchers say you have to cut more other things to help losing weight:
1. Your oversized handbag
We know those extra Easter eggs don’t help your battle with the dreaded muffin top, but your handbag? After noticing some of his patients carry more fat on one side of their body, cosmetic doctor Michael Prager realized that it was often the side on which the patients held their oversized handbags.
“Before I perform laser fat removal I measure where patients carry fat, so we can measure inch loss post-treatment,” Dr. Michael Prager says.
“Many of my female patients carry more fat down one side of their body and their fat stores were uneven. The only thing these women had in common was their ridiculously big handbags.”
Postural expert Ivana Daniell says that Dr. Michael Prager’s observations are due to the effects of heavy bags on our deportment. Over time, bad posture leads to distorted fat distribution.
“Our posture affects where we store fat,” Ivana Daniell says.
“If you do more weight-bearing exercises on one side – i.e. by carrying a heavy bag – you’re not only activating the muscles more on one side, you’re also creating a muscular and skeletal imbalance which can affect fat distribution.”
Her advice? “Don’t carry so much, because it affects your posture, and good posture makes you look slimmer. And switch your handbag from side to side.” As well as evening out fat stores, this will also reduce pain in your neck, shoulders, and back.

2. Fake tan
For years we’ve thought a fake tan will leave us looking slimmer and more toned. But could it actually make us fatter in the long run? Scientists in Sweden have discovered that chemicals known as phthalates in self-tanning lotions make us more prone to weight gain and twice as likely to develop diabetes.
The chemical is also found in make-up, cleaning products and plastic containers. The study has raised concerns that phthalates can encourage your body to store fat around the stomach area because they disrupt the hormone balance (in a similar way to puberty or the menopause) which can cause weight gain.
Study author Monica Lind says: “These phthalates are making people obese. Many are used in body products like fake tan and they are absorbed into the body and bloodstream through the skin.”
For most women, continuously switching between chores is part and parcel of daily life. But new research has found that serially switching tasks exhausts the part of our brain that regulates self-control.
“When you help your kids with their homework, then respond to a work email on your BlackBerry, then go right back to algebra, you’re doing tasks that require very different mindsets, which is what we found saps self-control resources,” says Professor Ryan Hamilton, who worked on the study.
“Being busy also affects the food choices you make,” says personal trainer Dalton Wong, who trains Hunger Games actress Jennifer Lawrence.
“If you’re so busy you can’t think straight, you’re more likely to grab a coffee and a pile of biscuits to keep going.
“However, while this type of snack provides a quick hit of energy, it will lead to more stress and exhaustion. Artificial sugar disrupts the body’s blood-sugar levels, leading to tiredness and more sugar cravings, and more than two or three cups of coffee will flood your body with the stress hormone cortisol.”
Dalton Wong advises never eating a meal while distracted (“You won’t chew properly because you’ll be in a rush, and this leads to bloating”).
He also says you should snack on nuts and berries, or vegetables and hummus, until you’re completely distraction-free.
That trusty wardrobe staple, a pair of black leggings, can hide a multitude of sins. But can wearing them too often make you fat? Sammy Margo, a physiotherapist who works with the England football team, has warned that too-tight leggings can cause your muscles to become lazy, which results in a flabby stomach, bottom and legs.
“Leggings feel good and look great, and I am as addicted to them as anyone, but there is a downside,” Sammy Margo says.
“They hold in and support the thigh muscles, buttocks and core muscles in your tummy, and do the job the muscles are supposed to do.
“As a result, the muscles are allowed to relax and switch off. So when we reveal our bodies for the first time as summer approaches, they are not as svelte or firm as they otherwise would be.”
Sammy Margo advises that people “should already be weaning themselves off their leggings if they want to look their best in time for summer”, and they should also try the String Workout.
“Suck your stomach in as far as it will go, then breathe out about halfway,” she explains.
“Tie a piece of string around your stomach at that point and keep it there all day.”
This ensures you’re working your abdominal muscles and not letting them get slack.
5. High heels
You wouldn’t believe it from looking at super-slim stiletto lovers like Victoria Beckham, but high heels can give you a pot belly. That’s the opinion of personal trainer Dax Moy, who thinks that wearing vertiginous heels too often can cause your stomach muscles to spill forward.
“Wearing very high heels causes the forward tilting of the pelvis, which allows the abdominal contents to spill forward, producing a pot belly which many women have wrongly come to think of as a fat stomach,” says Dax Moy.
Dalton Wong agrees. He says: “High heels can weaken your abdominals, leading to a tummy that sticks out just below your belly button. I tell my clients to wear their heels on the red carpet, but to slip them off once they’re sitting down.
“So wear them in a nice restaurant, but travel there in your trainers and put your heels on at the last minute. Then slip them off underneath the table once you’re seated. When you’re at home, walk around barefoot throughout the house. This strengthens muscles that have been weakened by wearing high heels.”
Losing weight just got twice as hard because of a new way of calculating the effects of dieting.
Conventional guidelines fail to take into account changes in metabolism, says U.S. expert Dr. Kevin Hall.
As a result, dieting is always going to be a struggle, Dr. Kevin Hall argues. Cutting calories leads to a slowing of metabolism which means it takes longer to lose weight.
At a rate of 100 calories lost per day, it would take the average person a year to shed 5 lbs of body weight.
Under the “old” guidelines, based on the idea that each pound is equivalent to 3,500 calories, the same degree of weight loss should be possible in roughly half that time.
Speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) in Vancouver, Canada, Dr. Kevin Hall said: “People have used this rule of thumb to predict how much weight people should lose for decades now, but it turns out to be incredibly wrong.
“The reason it’s wrong is because it doesn’t account for the metabolic changes that take place when people change their diet.
“We know that if you cut the calories in somebody’s diet their metabolism starts to slow down, and it slows down more and more the more weight that is lost. So eventually you’ll reach a plateau.
“Some of my work has been to develop realistic mathematical models about what happens to metabolism when people start changing their diets and can we come up with some better rules and better predictions.”
Cutting calories leads to a slowing of metabolism which means it takes longer to lose weight
Because of the way metabolism slows weight loss, dieting away 100 calories daily would lead to the loss of just 10 lbs in three years, said Dr. Kevin Hall, from the Laboratory of Biological Modelling in Maryland.
Five pounds of that weight loss would go in the first year.
Dr. Kevin Hall has developed an online slimming aid that explains what level of dieting is needed to achieve a weight loss target. It takes numerous factors into account including metabolism.
The website (bwsimulator.niddk.nih.gov) is designed to assist researchers rather than members of the public, though anyone can access it.
Dr. Kevin Hall said: “Instead of using that old rule of thumb that we now know is incorrect, people can plug in what their goal weight might be in a specific time period.
“What the model will do is simulate what changes in diet and exercise that person will have to do to achieve that goal weight and even more importantly what they have to do permanently to maintain that weight loss.”
