Exercise For Fat Loss

This article has been provided by guest author Kyle Wood known as one of the best among up and coming Melbourne personal trainers.  Kyle has a keen interest in new and more effective training for himself and his clients and he believes exercise should contribute to your life and make it more fruitful rather than detract from it. He currently runs a blog in his spare time called Kyle’s Fitness Facts so take a look there if you want to know more...

Exercise for Fat Loss

Diet is very important when losing weight. The best training system in the world cannot out do a terrible diet filled with junk food, irregular meals and no veggies. However, as you reduce your caloric intake your body adapts to that caloric intake and the weight loss will plateau. This is where a lot of people will give up, however for those who continue, more calories must be cut and so on. This reaches a point where the calories are cut so low that you begin to starve your body.

A better solution to making that second cut in calories (or even the first) is to add exercise. If you are already exercising regularly then I suggest adding more intense workouts to your training schedule.  Here are some great ideas (that can all be done without a gym membership):

Sprint Intervals

Find your local track or oval (soccer pitches work excellent). Start off by doing one or two laps to warm up and then follow this cycle:

  • Jog 50m
  • Sprint 50m
  • Walk 50m

Repeat this 4 times. Each week add an additional cycle until you reach 10 cycles. When you can do that move onto something new.

Note: A full size soccer pitch is 50m wide and 100m long so you can complete 2 cycles in one lap.

Circuit Training:

I’m not talking about walking around in a circuit on weight machines for 30 minutes, I’m talking all out circuits that will get your heart pumping through your chest and your fat cells dropping like flies. For these circuits you will need a railing or play equipment bar about 1.2m (4 feet) off the ground and a low bench or steps.

Circuit 1:

  • Feet elevated push up x12 (on knees if unable to do on toes)
  • Bodyweight squat x12
  • Crunches x 12
  • Butt Kick Jumps x12

Repeat 2 times before moving onto circuit two

Circuit 2:

  • Burpees x10
  • Inverted row (on railing) x10
  • Forward Walking Lunges x5
  • Reverse Walking Lunges x5
  • Pushups x10

Repeat 2 times. Each week add an extra circuit to one of the circuits until you reach a total of 10 circuits.

Hill Sprints

Find a small hill. Sprint to the top, walk back down, rinse, repeat. You will be amazed at how awesome this simple activity is for cardiovascular fitness and fat shedding. Do this 5 times and then add an extra sprint each week.

Remember to warm up thoroughly beforehand and then warm down and stretch afterwards. This applies when doing any exercise.

You want more?

If you work your way up to doing all of that in a week then you can add low intensity recovery cardiovascular work to your off days. This kind of exercise is excellent at promoting blood to muscles to aid in recovery from your previous workouts. Good ideas are swimming, bike riding or brisk walks with your partner/family/dog.

Give these high intensity techniques a go. Stick to them for at least 6 weeks before you truly give them your analysis. I believe by then you will be addicted to high intensity training. Not only will they help you lose weight faster but you will also have more energy and feel more alert. Before I go, some great fun facts:

  • Muscle requires more energy to exist, so the more muscle you have, the faster your metabolism.
  • 20-30 minutes high intensity training burns more total energy (calories) over 24 hours than 60 minutes of low-moderate total training.
  • Recent studies are continuing to show that the lactic acid system (shorter bursts of energy like sprinting and circuits) is a far greater channel for fat oxidizing (fat burning) than the aerobic study (longer low intensity training) which might explain why sprinters are so ripped.

Treatments improve for breast cancer patients

HOUSTON -- (October 15, 2009) -- More women are surviving breast cancer as a result of improvements in early detection methods and more effective, targeted treatment, say experts at Baylor College of Medicine.

"We continue to make great strides in research and patient care," said Dr. Heather West, assistant professor in the Lester and Sue Smith Breast Center at Baylor College of Medicine. "Survival rates have greatly improved the past 10 years."

Early detection

Early detection remains key to survival, West said. Advancements have improved doctors' ability to catch the tumors when they are at a curable stage.

"Yearly screening mammograms have shown to be most effective in women from age 50 to 70," said West. "However, it is recommended that all women begin them at age 40."

Patients with a family history of breast cancer are at a higher risk and should begin screening at age 35, West said.

"Mammograms are not as sensitive in younger women because most have dense breast tissue," West said. "In younger women, we use ultrasounds. Breast magnetic resonance imaging, or MRI, is useful in selected high-risk populations."

Research advancements

Advancements in genetic research have enabled clinicians to evaluate which treatments may work better for a certain patient.

"Now we can look at how the tumors change at the molecular and genetic level with treatment," said West. "This helps clinicians determine how patients may respond to different treatments, and it rationally guides them on the development of new treatment targets."

Common approaches

The most common approaches to breast cancer treatment include:

  • For hormone-sensitive tumors (estrogen-receptor positive and progesterone-receptor positive), Tamoxifen (premenopausal) and the newer aromatase inhibitors (postmenopausal)
  • For patients with HER-2 gene amplification, anti-HER-2 antibodies (Trastuzumab) in combination with chemotherapy
  • For patients that have no hormone sensitivity or HER-2 amplification, or triple negative tumors, chemotherapy

Researchers are currently investigating new agents to treat triple-negative tumors, which are a rare, aggressive subtype of cancer that affects approximately 15 percent of all breast cancer patients.

Some of the most promising research announced in the last year focuses on PARP, or Poly (ADP-ribose) polymerase, inhibitors, which have been shown to be effective in this subtype of breast cancer, West said.

"In certain types of cancer, there is a defect in DNA repair pathways and mutations develop," said West. "PARP is an enzyme involved with DNA damage repair. PARP inhibitors actually impair the tumor's ability to repair damage, thus killing tumors more effectively."

Medicaid pay could be cut again when stimulus money runs out

Federal stimulus funding has helped state Medicaid programs avoid drastic reductions in eligibility and physician fees, but program directors already are contemplating such cuts when the additional federal support runs out at the end of next year.

States faced unprecedented financial pressures in fiscal 2009, which ended on June 30 for most states. They experienced a surge in new Medicaid enrollees and a historic decline in tax revenues. States coped by trimming or freezing Medicaid fees and restricting benefits, among other actions, according to a ninth annual survey of state Medicaid directors released Sept. 30 by the Kaiser Family Foundation and Health Management Associates.

Medicaid enrollment grew by 5.4% in fiscal 2009 -- the highest rate in six years -- while total program spending increased by 7.9%, the fastest pace in five years. The enrollment spike was the main reason spending grew, according to report co-author Vernon K. Smith, PhD, principal with Health Management Associates. "As more people lost their jobs and lost their health coverage, more people became eligible."

Meanwhile, state revenues plummeted: Tax collections dropped by 16.6% in the 12 months leading up to June 2009, according to U.S. Census Bureau statistics. This contributed to a 6.3% decline in the state portion of Medicaid spending -- the first in the program's history, Smith said.

But the 2009 Medicaid cuts would have been much worse without the most recent federal stimulus package, Smith said. "Without any doubt, we would have seen widespread cuts to eligibility. Cuts to benefits and provider payment rates would have been much, much more severe." Twenty-nine states said they would have cut Medicaid eligibility had the stimulus act not prohibited them from doing so as a condition of accepting the additional Medicaid funding, the report said. Fourteen states had to reverse enacted cuts to obtain the federal money.

Medicaid enrollment grew by 5.4% in fiscal 2009.

Despite the stimulus, states are far from being on solid financial ground, Smith said. The additional federal Medicaid funding expires on Dec. 31, 2010. State revenues probably would not rebound for a year or two even under an immediate economic recovery, and Medicaid enrollment likely would remain steady for many months to come, he added.

Medicaid directors are worried about conditions when the stimulus funding runs out. For example, Nevada would need to find about $240 million in fiscal 2010 to maintain its existing Medicaid program, said Charles Duarte, administrator of the Division of Health Care Financing and Policy at the Nevada Dept. of Health and Human Services. New York would have to find about $6 billion for its Medicaid program, said Deborah Bachrach, the state's Medicaid director.

Some said Medicaid cuts that were unthinkable a few years ago may be necessary. Duarte said Nevada might reconsider a list of potential cuts he prepared last year that weren't implemented -- including wholesale elimination of eligibility groups, restricted home- and community-based benefits, and reduced hospital and physician Medicaid pay. "This could affect access, but we're at the point where that may be a secondary consideration."

Bachrach said physician Medicaid pay is an obvious target. New York increased payments by more than 50% in recent years in an effort to get them closer to Medicare levels. "That is one of the goals that may be shortchanged as a result of the plummeting resources."

Medicaid pay on the chopping block

Nine states cut physician Medicaid fees in fiscal 2009, and 13 have adopted pay cuts for fiscal 2010 -- the most since the Kaiser Family Foundation and Health Management Associates began tracking doctors' fees in 2004. But the situation could have been -- and still could be -- much worse.

Although legislatures have closed billions in budget gaps, they could face combined deficits of $350 billion in their 2010 and 2011 budgets, according to Robin Rudowitz, principal policy analyst for the Kaiser Commission on Medicaid and the Uninsured.

Additional Medicaid funding from the stimulus package expires on Dec. 31, 2010.

Also, spending and enrollment projections for 2010 don't add up, Smith said. State budgets predict an average 6.3% growth in Medicaid spending, but enrollment is expected to grow by 6.6%, the report found. State budget shortfalls are likely so large as to prevent states from matching expected enrollment growth with general funds, he said.

Washington state physicians, like those in California and Utah, saw Medicaid fees reduced for 2009 and 2010. "We had some increases the session before, and they took those increases away," said Jennifer Hanscom, spokeswoman for the Washington State Medical Assn.

The report found that some states, such as Maine, managed to boost Medicaid pay for office-based physicians for 2009 and 2010. But Maine's increases came at the expense of hospital-based physicians, said Andrew MacLean, deputy executive vice president of the Maine Medical Assn.

Other states' Medicaid rates essentially are holding steady. South Carolina trimmed Medicaid fees for physicians in 2009 before reversing the cuts for 2010, said Gregory Tarasidis, MD, president-elect of the South Carolina Medical Assn. But continued budget deficits could threaten those fees, he said.

Balking at the expansion price tag

Smith said state Medicaid directors are confident that the program could provide quality coverage to millions more low-income people without health insurance. But they're concerned that Congress will ask states to shoulder too much of the cost.

The House and Senate health system reform bills would expand Medicaid eligibility to any citizen earning 133% or less of the federal poverty level. Seventeen states offer some coverage to childless adults, but it is often very limited.

The House bill would pay for the expansion using only federal funds, but the pending Senate bill would provide less federal support to states that already enacted Medicaid expansions, such as New York. "In essence, we're being penalized for the decisions we've made in past years to invest state dollars to cover people who are very low-income individuals," Bachrach said.

Smith said states probably are waiting to see what Congress does on reform instead of adopting their own health care expansions. "If you go ahead and enact a change now, you will not be rewarded in the future."

GAO finding on potential Medicare overuse attracts lawmaker attention

Washington -- Backed by a recent government watchdog report, one key lawmaker is making the case that not only is beneficiary access to Medicare doctors good, in some areas patients might be accessing too many services.

Senate Finance Committee Chair Max Baucus (D, Mont.) commissioned the Government Accountability Office to assess the level of physician services used in the program. The agency determined that Medicare patients experienced few problems accessing doctors, and the use of services increased nationwide from 2000 to 2008. Physician willingness to accept Medicare patients also increased during that time, as did payments.

But the report, released Sept. 28, detected a pattern of potential overuse of services, especially in more densely populated urban regions and in the eastern part of the U.S.

Large metropolitan areas were much more likely to be "potentially overserved" than were rural areas, the GAO found. Patients in these areas received substantially more evaluation and management services, minor procedures and imaging services than did those living in other areas.

Beneficiaries in potentially overserved areas on average received 44% more minor procedures in 2008, including ambulatory procedures, eye treatments and colonoscopies. They also had 29% more laboratory tests and 19% more imaging services than those in other areas, the GAO reported.

Medicare patients nationwide used more services in 2008 than in 2000.

These findings of potential overuse did not sit well with Baucus. Part of the health system reform effort he is leading in the Senate is focused on squeezing dollars out of Medicare without harming beneficiary access.

"This report makes clear that serious work remains in determining why the use of certain services under Medicare -- like imaging and minor procedures -- is much higher in certain parts of the country than others, irrespective of a patient's real need, health status or the availability of doctors," he said. "Moreover, the potential abuse and excessive spending revealed in this report is further evidence the status quo of rising health care costs is unacceptable for America's seniors and the long-term fiscal health of the Medicare program."

But physician organizations said the situation was more complex than it might appear. For instance, some services may seem to be overused in certain areas of the country simply because they are medically necessary for the higher volumes of patients that live there, said American Medical Association President J. James Rohack, MD.

"The medical profession is committed to addressing variations in care, but it's important to note that high growth in services does not always equal overuse," Dr. Rohack said. "For example, services that the GAO identified as growing rapidly, like colonoscopies and office visits, are encouraged by Medicare policymakers to promote early detection, prevent disease and manage chronic conditions."

Dr. Rohack noted that the issue is too complicated for such broad solutions as redistributing funds from low-spending to high-spending areas. He said the most successful interventions on the utilization issue will be based locally.

"Through the AMA-convened Physician Consortium for Performance Improvement, physicians are developing evidence-based appropriateness measures that can be implemented at the point of care, and are working to integrate these and other quality measures into electronic medical records," he said.

The argument against cuts

While the GAO found that very few Medicare beneficiaries reported significant problems accessing physician services, the agency did note that the legislative uncertainty surrounding doctor fees points to an ongoing need to monitor access. Medicare physician payments are projected to be cut by 21.5% in January 2010 unless Congress intervenes, and additional years of reductions are set to follow.

"Absent congressional action, the Medicare trustees project payment cuts of about 40% over the next five years to physicians caring for Medicare patients," Dr. Rohack said. "Our concern, shared by AARP and lawmakers, is that these looming cuts will make it difficult for physicians to care for today's seniors and the huge influx of baby boomers into the Medicare program. Permanent repeal of the current payment formula should be part of health reform to keep physicians caring for seniors."

Despite the report's findings on imaging, the American College of Radiology said the overall growth rate for medical imaging in the Medicare system is down dramatically. The Medicare Payment Advisory Commission, for example, found the nationwide imaging growth rate for 2006-07 to be only 2%, which is less than the figure for the growth of physician services as a whole, said Shawn Farley, an ACR spokesman.

"The ACR has addressed unnecessary utilization for the last 20 years via the development of extensive practice guidelines, facility accreditation programs and appropriateness criteria to aid referring physicians regarding which, if any, scan should be prescribed for a given indication," Farley said. "Our highest legislative priority has been to get the Congress and the administration to adopt these utilization strategies for the Medicare program."
