Being overweight or obese ‘linked to 10 common cancers’
By Smitha Mundasad
Health reporter, BBC News

Researchers suggest obesity’s effects on cancers vary depending on the type of tumour

Being overweight and obese puts people at greater risk of developing 10 of the most common cancers, according to research in the Lancet medical journal.

Scientists calculated individuals carrying this extra weight could contribute to more than 12,000 cases of cancer in the UK population every year.

They warn if obesity levels continue to rise there may be an additional 3,700 cancers diagnosed annually.

The study of five million people is the largest to date to confirm the link.

This variation tells us BMI must affect cancer risk through a number of different processes, depending on cancer type”

Dr Krishnan Bhaskaran
Lead researcher

Large numbers
Doctors often warn being overweight can increase the risk of developing cancer, but this study highlights those forms of the disease where the risk is greatest.

Led by scientists from the London School of Hygiene and Tropical Medicine researchers gathered data on five million people living in the UK, monitoring changes to their health over a period of seven years.

They found each 13-16kg (2-2.5 stone) of extra weight an average adult gained was linked firmly and linearly to a greater risk of six cancers.

How big this risk was varied depending on tumour type.

Cancer of the uterus had the highest increased risk
gallbladder
kidney
cervix
thyroid
leukaemia had the lowest rise in risk.

People who had a high body mass index (calculated using weight and height) were also more likely to develop cancer of the liver, colon, ovaries, and post-menopausal breast cancer.

But the effects for these cancers were less clear-cut and were influenced by individual factors such as the menopause.

Researchers say though obesity was associated with the development of the most common cancers – which represent 90% of the cancers diagnosed in the UK, some showed no link at all.

And there is some evidence to suggest a higher BMI is associated with a lower chance of getting prostate cancer.

Modest risks
Dr Krishnan Bhaskaran, who led the research, said: “There was a lot of variation in the effect of BMI on different cancers.

“For example, risk of cancer of the uterus increased substantially at higher body mass index, for other cancer we saw a more modest increase in risk or no effect at all.

“This variation tells us BMI must affect cancer risk through a number of different processes, depending on cancer type”

Tom Stansfeld, at Cancer Research UK, said: “Although the relationship between cancer and obesity is complex, it is clear carrying excess weight increases your risk of developing cancer.

“Keeping a healthy weight reduces cancer risk and the best way to do this is through eating a healthy, balanced diet and exercising regularly.”

Obesity Raises Breast Cancer Death Risk in Pre-Menopausal Women
By Nicole Ostrow May 15, 2014

Women younger than 50 who are obese and have a common form of breast cancer have a higher risk of dying from the disease than women with the cancer who are normal weight, researchers said.

20140525-102124.jpg

Being obese was associated with a 34 percent increased chance of breast cancer death in pre-menopausal women with estrogen receptor-positive disease, which responds to hormone treatment, an analysis of 70 clinical trials found. The study, released yesterday, will be presented at the American Society of Clinical Oncology meeting beginning May 30 in Chicago.

The research is among the latest to tie obesity to cancer risk and the largest to examine weight’s role in the prognosis of estrogen-receptor positive breast malignancy and menopausal status, the authors said. Obesity is associated with increased dangers of other cancers including esophagus, endometrium, colon, kidney, pancreas, thyroid and gallbladder, according to the National Cancer Institute.

“This study is part of the growing body of evidence showing that patients who are obese generally fare worse with cancer –- in this case, younger women with breast cancer,” Clifford Hudis, president of the cancer doctors’ group, said in a statement. “With some two-thirds of our nation’s adult population now obese or overweight, there’s simply no avoiding obesity as a complicating factor in cancer care.”

Breast cancer is the most diagnosed cancer among U.S. women, according to the Centers for Disease Control and Prevention. Two-thirds of all breast tumors are fed by estrogen, according to the National Institutes of Health. More than 230,000 women in the U.S. will be diagnosed with breast cancer this year and 40,000 will die.

Study Results

The study’s results showed no association between weight and death in post-menopausal women with estrogen receptor-positive disease, a surprise finding because obesity increases blood estrogen levels in older women, said lead study author Hongchao Pan.

“This is exactly the opposite of what we expected,” Pan, a senior research fellow at the University of Oxford in the U.K., said in a telephone interview. “We know the effect is definite and real. We don’t know the mechanisms that underlie the association at the moment.”

Researchers in the study looked at 80,000 women in 70 clinical trials. Of those, 20,000 were pre-menopausal with ER-positive disease, 40,000 had ER-positive disease and were post-menopausal and 20,000 were pre-menopausal with ER-negative disease.

They found that both overweight and obese pre-menopausal women had a higher risk of dying from ER-positive breast cancer compared with women who were normal weight.

Less Than 30 mins activity in 28 days!

20140205-155030.jpg

I truly believe we can do better.
Community fitness classes and cheap gyms haven’t made the impact hoped for.

A few days ago I saw a report about special Aqua sessions for those with very high BMI.

This morning I received the report below, and want to DO something about the situation. I’ve been teaching fitness since 1983, seniors since 1995 and Fatloss since 2009.
Last year I qualified as a Metabolic coach so know I could make a difference, if I can get them involved.

I’m looking for studio space and more important Pools to use and promote. If you can help please get in touch!

ukactive release ‘Turning the tide of inactivity report’
Today, ukactive have released the “Turning the tide of inactivity” report which has used local authority figures to calculate the number of people that are officially classed as “inactive” because they did not carry out half an hour of exercise in a 28 day period.

Problems resulting from a sedentary lifestyle are blamed for 17 per cent of premature deaths and cost the economy more than £8bn a year.

In the report, ukactive said: “Over the past 50 years, physical activity levels have declined by 20 per cent in the UK, with projections indicating a further 15 per cent drop by 2030.

“If this trend continues, by 2030 the average British person will use only 25 per cent more energy than they would have done had they just spent the day in bed.”

In the report Lord Sebastian Coe said: “Supporting people that do little or no daily activity to become a bit more active is where the biggest public health gains can be made.”

James Samuel, Event Director of Leisure Industry Week (LIW) said: “LIW are fully committed to helping ukactive in their mission to turn the tide of inactivity and get the country fit and healthy. We urge our LIW community to also continue to push the message to their own customers and databases so as an industry we can help make a difference.”

This report is a must read as it contains insight at a national and local level. Use this link to view the full report. http://www.liw.co.uk/inactivityreport/

Please pass this on to anyone you think might help, either by spreading the word, providing space a pool or funding for this community project.

Nutrition Guidelines Cause Obesity and Diabetes January 14, 2014

I thought I should post this – it covers how many food and diet lies got started and how the proof, the studies are flaky or non existent.

Modern Nutrition Policy is Based on Lies and Bad Science
January 19, 2013 by Kris Gunnars

The Seven Countries Study

Ancel Keyes

20131110-122830.jpg
In the year 1958, an American scientist called Ancel Keys started a study called the Seven Countries Study, which examined the association between diet and cardiovascular disease in different countries.

The study revealed that the countries where fat consumption was the highest had the most heart disease, supporting the idea that dietary fat caused heart disease.

The problem is that he intentionally left out:

Countries where people eat a lot of fat but have little heart disease, such as Holland and Norway.
Countries where fat consumption is low but the rate of heart disease is high, such as Chile.
Basically, he only used data from the countries that supported his theory, a process known as cherry picking.

This highly flawed observational study gained massive media attention and had a major influence on the dietary guidelines of the next few decades.

The McGovern Committee

20131110-122558.jpg
George McGovern

In 1977, an American committee of the U.S. senate led by George McGovern published the first Dietary Goals For The United States in order to reverse the epidemic of heart disease in the country.

These guidelines received massive criticism at the time from many respected scientists like John Yudkin (who insisted that sugar was to blame) and the American Medical Association.

Basically, the dietary goals were:

Eat less fat and cholesterol.
Less refined and processed sugars.
More complex carbohydrates from vegetables, fruits and grains.
These guidelines were picked up by the USDA (United States Department of Agriculture) – very convenient for them since their job is to sell grains.

Basically, a low-fat, high-carb diet… for everyone.

20131110-122932.jpg
The whole guidelines were based on observational studies made by biased scientists and had nothing even closely resembling scientific proof to back them up.

Since then, many randomized controlled trials have shown that this dietary approach doesn’t really work for the people it was meant to help.

An interesting fact is that the obesity epidemic started around the time these guidelines were published and the diabetes epidemic followed soon after.

Nutrition is Stuck in a Paradigm Based on Lies and Bad Science

It is important to realize the massive significance of this.

20131110-122125.jpg

This idea that saturated fat caused heart disease was the cornerstone of modern nutrition policy and the reason health authorities turned away from a higher fat diet rich in animal foods, towards a low-fat, high-carb diet with plenty of grains.

Even though saturated fat has now been proven to be harmless, modern nutrition is still stuck in that same paradigm based on cherry picking, lies and just plain bad science.

Nutritionists are still preaching the low-fat, high-carb dogma that has pretty much been proven to be ineffective for the majority of the population and may even be downright dangerous for some people.

2/13 Nutrition Lies That Made The World Sick And Fat – Calories November 3, 2013

2. A Calorie is a Calorie

20131031-225100.jpg

It is often said that the only thing that matters for weight loss is “calories in, calories out.”

The truth is that calories matter… but the types of foods we eat are just as important.

That is because different foods go through different metabolic pathways in the body (14).

Additionally, the foods we eat can directly impact the hormones that regulate when and how much we eat, as well as the amount of calories we burn.

Here are two examples of why a calorie is NOT a calorie:

Protein: Eating protein can boost the metabolic rate and reduce appetite compared to the same amount of calories from fat and carbs. It can also increase your muscle mass, which burns calories around the clock (15, 16).
Fructose vs glucose: Fructose can stimulate the appetite compared to the same number of calories from glucose (17, 18).
Even though calories are important, saying that they are all that matters when it comes to weight (or health for that matter) is completely wrong.

Bottom Line: All calories are not created equal. Different foods go through different metabolic pathways and have varying effects on hunger, hormones and health.

Obesity and Pancreatic Cancer October 24, 2013

Obesity Before Pancreatic Cancer Shortens Survival
Nick MulcahyOctober 21, 2013

20131023-110617.jpg

Patients with pancreatic cancer who were obese in the years before their diagnosis have reduced survival, according to research published online today in the Journal of Clinical Oncology.

The investigators found that patients with pancreatic cancer who had a prediagnostic body mass index (BMI) in the obese range lived 2 to 3 months less than patients who had a healthy weight before their diagnosis.

They used prospectively collected BMI data on 902 patients with pancreatic cancer from 2 large, long-term cohort studies of health professionals.

Findings from previous case–control studies have been similar, but they were retrospective. Results from this prospective study strengthen the evidence on the subject, according to one expert.

“While previous retrospective studies suggested a link between obesity and pancreatic cancer survival, the prospective nature of this study makes the findings more reliable,” said Smitha S. Krishnamurthi, MD, from Case Western Reserve University in Cleveland, in a press statement. She was not involved with the study, but offered her comments as a member of the Cancer Communications Committee at the American Society of Clinical Oncology.

Clinicians can share the results with patients in general practice and oncology, suggested a study author.

“This study adds to mounting evidence for the role of weight control in improving outcomes for patients with cancer. It also reinforces the importance of maintaining a healthy weight throughout your life, which may lead to better outcomes after diagnosis and help prevent pancreatic cancer from developing,” said senior study author Brian M. Wolpin, MD, MPH, from the Dana-Farber Cancer Institute and Harvard Medical School in Boston, in a press statement.

Obesity Independent of Other Factors

Dr. Wolpin and his colleagues found that the association between prediagnostic BMI and survival was independent of other known predictors of survival with this cancer.

On a multivariable analysis that compared especially obese patients (BMI ≥35 kg/m²) with healthy-weight patients (BMI <25 kg/m²), the adjusted hazard ratio (HR) for death was 1.53 (P trend < .001). The analysis adjusted for differences in age, sex, race/ethnicity, smoking status, and disease stage.

The association between obesity and shortened survival was statistically strongest for people who were overweight 2 decades before their diagnosis. Specifically, in a subset of 202 patients for whom BMI collected 18 to 20 years before diagnosis was available, the HR for death was 2.31 (P trend = .001).

Dr. Wolpin and colleagues acknowledge that they used overall — not disease-specific — survival, which is a limitation of their study. However, pancreatic cancer is so lethal, overall survival is "a good surrogate," they say.

Median overall survival for all patients was 5 months. For patients with metastatic disease, median survival was 3 months; for patients with advanced disease, it was 8 months; and for patients with localized disease, it was 16 months.

Pancreatic cancer is the fourth leading cause of cancer-related death in the United States. Most patients with pancreatic adenocarcinoma, which accounts for more than 90% of new cases, survive less than a year after their diagnosis. Only 5% survive 5 years after diagnosis, the investigators report.

This study not only strengthens the literature on BMI and pancreatic cancer outcome, it adds to a relatively limited body of information about prognostic factors, they note.

For those with pancreatic cancer, "the length of patient survival is greatly influenced by disease stage at presentation, but few other markers of survival have been well characterized," they write.

Obese Patients Tend to Present With More Advanced Disease

The investigators evaluated the association between BMI in 1970s and 1980s and survival after a diagnosis of pancreatic cancer in participants from two cohorts: the Nurses' Health Study and the Health Professionals Follow-up Study.

Participants were surveyed on demographics, medical history, and health behaviors. Deaths were ascertained from next of kin, the postal service, and the National Death Index.

The investigators used World Health Organization (WHO) criteria to categorize body mass. A BMI from 18.5 to 24.9 kg/m² was considered healthy weight, from 25.0 to 29.9 kg/m² was considered overweight, and 30 kg/m² or higher was considered obese. For some analyses, the sample size was adequate to further classify the obese group into 2 categories: 30.0 to 34.9 kg/m² and 35 kg/m² or higher.

No statistically significant differences were seen in study cohort, smoking status, or disease stage. However, when baseline BMI groups were compared (≥35 vs <25 kg/m²), the association was stronger for never-smokers (HR, 1.61; P trend = .002) than for ever-smokers (HR, 1.36; P trend = .63).

Higher prediagnostic BMI was also associated with more advanced stage at diagnosis. More patients with a BMI of 30 kg/m² or higher presented with metastatic disease than with a BMI below 25 kg/m² (72.5% vs 59.4%; P = .02).

This study was partly funded by the National Cancer Institute, the American Society of Clinical Oncology Conquer Cancer Foundation, the Howard Hughes Medical Institute, the Lustgarten Foundation, and Promises for Purple. The authors have disclosed no relevant financial relationships.

Scientists Discover One Weird Way To Better Heart Health (and fat loss) October 3, 2013

Scientists Discover One Weird Way To Better Heart Health (and fat loss)

By Kevin DiDonato MS, CSCS, CES

There are an increasing number of people that are at risk for developing heart disease.

And, they are not just at risk because of the common issues – altered cholesterol levels, inactivity, or smoking – but, by more uncommon issues.

One of the reasons for the sudden spike in cardiovascular risk: overweight, obesity, altered cholesterol levels, and insulin resistance.

More commonly referred to as metabolic syndrome, this condition may be leading to more health related issues than ever before.

But there is good news!

There is ONE nutrient that, research shows, may slow the rise in blood lipid levels, alter cholesterol metabolism, and even reduce inflammatory states associated with being overweight or obese.

And, to say this nutrient is important, well, that would be the BIGGEST understatement of the year…

Omega-3 and Cholesterol Metabolism

According to this study, elevated cholesterol levels combined with being overweight or obese, and insulin resistant may set the stage for future adverse heart health conditions.

And the sad fact is: There are more overweight or obese people in this country – and around the world – that may suffer from this unfortunate and, often times, preventable health condition.

Now, studies also show that omega-3 fatty acids may do some wonderful things inside your body.

From increasing adiponectin levels (fat burning protein) to improving blood lipid levels, omega-3 fatty acids have been shown to improve many aspects of your health.

Although there are many people that consume omega-3 fatty acids – from krill oil, almonds, olive oil, etc. – there may also be a large number of people who don’t.

And this could be leading to a serious health epidemic.

Now, back to the study…

Researchers attempted to see if increasing omega-3 fatty acid intake – through supplementation or in the diet – could positively affect elevated cholesterol levels and inflammation in the body.

Here’s what they found:

They found that omega-3 fatty acid supplementation resulted in a significant improvement – or decrease – in the postprandial response for triglycerides, apoB48, and lipopolysaccharide binding protein (LBP) when compared to controls.

ApoB48 is a molecule in the body that is responsible for transporting cholesterol to the tissues in your body.

And LBP is a protein that binds to bacterial lipopolysaccharides that creates an immune response by your body.  In simple terms, it binds to a molecule that creates inflammation.

The researchers also showed that supplementing with omega-3 fatty acids resulted in a decrease in body weight gain and an increase in adiponectin – with a reduction in food intake – compared to the control group.

What did they conclude?

“Acute dietary omega-3 supplementation can improve fasting as well as postprandial lipid metabolism and components of the associated inflammatory response in the JCR:LA-cp fat.  Further, moderate dose omega-3 supplementation may reduce corresponding body weight during conditions of hypercholesterolaemia and/or decrease inflammation associated with obesity and the metabolic syndrome.”

More Omega-3 Fatty Acids

Omega-3 fatty acids have been linked to a lower risk for heart disease, improved eye health, improved brain function, and even improvements in reproductive health.

Now, according to this study, people who suffer from metabolic syndrome (collection of health issues such as high blood pressure, high cholesterol, and insulin resistance) may benefit from the use of omega-3 fatty acids.

From improvements in lipid metabolism to lowering inflammation, this study shows that omega-3 fatty acids may provide positive health benefits for people suffering from metabolic syndrome and who are overweight/obese.

So if you’re looking for a way to boost your health, heart health, or overall health, then taking a high quality omega 3 fatty acid supplement may be the answer for you.

A bit technical but important info!
