Wednesday, May 23, 2012 the Phase IV and Dr. Chris Renna will examine the relationship between diet, exercise and disease explaining how simple dietary changes and science based exercise can prevent and in some cases reverse diseases and conditions that plague our largely sedentary society.
Everyday we read how chronic conditions associated with inactivity and obesity, such as diabetes, high blood pressure, cardiovascular disease and cancer are the leading killers in Western societies and are increasing exponentially in developing nations as well. In fact, obesity, diabetes, and hypertension are now even commonplace in children. Overwhelming evidence from a variety of sources including epidemiological, prospective cohort, and intervention studies point to relatively simple solutions to the epidemic of these diseases: science based exercise and a healthy diet. Learn the simple and ordinary things you can do to achieve extraordinary results in your health and appearance. Hear how subtle changes in diet and exercise can make positive and long lasting changes in the quality of life and longevity.
This Lecture will include:
The dynamics of poor dietary choices and inadequate levels of activity and disease
Discussion of the effects of exercise and diet in the prevention of chronic disease
Highlights of the effects of lifestyle modification for both mitigating disease progression and reversing existing disease
Suggestions of potential mechanisms for beneficial effects.
Simple steps you can take now to create a new you!

Talk about unrealistic. The study suggesting that allowing 16 hours between dinner and the next meal will help you lose weight is ridiculous.
Assuming you finish dinner as early as 6 p.m. (unlikely, especially if you prepare it after work), waiting 16 hours until the next meal means 10 a.m., too late for breakfast before work or school. And skipping breakfast is associated with weight gain, according to many other studies.
Avoiding snacks after dinner is good advice, but otherwise the article is yet another reminder that we are not rats.

In the Woody Allen movie Sleeper, scientists of the future determine that steak, cream pies, and hot fudge are good for you.
In other words, if I may quote another ’70s comedy icon, everything you know is wrong.
This is especially true in the constantly evolving world of food, weight gain, and dieting. The latest news comes from a mathematician, Carson C. Chow, in a paper he gave to the American Association for the Advancement of Science and an interview with the New York Times.
Mr. Chow works for the National Institute of Diabetes and Digestive and Kidney Diseases, specializing in obesity, which now afflicts one out of every three Americans. In fact, he notes, over the last 30 years, the weight of the average American has increased by 20 pounds. So he and a colleague, Kevin Hall, decided to look at the problem through mathematics.
Mr. Hall is a mathematical physiologist, so the two of them worked out a formula to predict what people will weigh when you factor in their body size, how many calories they consume, how much they exercise, and so on.
Before we get to their results, I just have to say this: A mathematical physiologist? There really is such a thing? In the community of nerds, of which I am a proud member, that has to be the coolest job ever. Well, maybe after astronaut.
The big headline news that came out of Mr. Chow and Mr. Hall’s calculations is their answer to the question of why so many Americans (and increasingly, people worldwide) are overweight and obese. They see a direct correlation between the gain in weight and the increased production of food.
“Beginning in the 1970s, there was a change in national agricultural policy. Instead of the government paying farmers not to engage in full production, as was the practice, they were encouraged to grow as much food as they could,” Mr. Chow told the Times.
At the same time, farming techniques continued to be more efficient. Farms produced more food than ever, outpacing the rate of population growth. Doing the math (they’re big on math), they determined that there are now 1,000 more calories available to Americans than there were in the 1970s.
What do we do with all that extra food and all those extra calories? We eat them.
You’ve probably heard how much food Americans throw out these days. Everyone bemoans this huge amount of waste, but Mr. Chow points out that if we were discarding less food, we as a nation would be even heavier.
This theory can also be applied to the sense, shared by many, that the proliferation of restaurants and our increasing habit of going out to eat are also leading to our weight gain. According to Mr. Chow, the huge increase in the food supply has made restaurants cheaper. And cheaper food has led to more fast food restaurants.
But it was their other mathematical discoveries that interested me even more. Perhaps you know the theory that if you eat 3,500 fewer calories (or work off a similar amount) you will lose one pound.
According to the mathematicians, everything you know is wrong.
They found that the body changes as you gain or lose weight. Obese people gain weight faster from the same number of calories. As Mr. Chow put it, “an extra 10 calories a day puts more weight onto an obese person than on a thinner one.”
They also discovered that one of the most vital factors in all diets is time. They found it takes three full years for your body to adjust to a diet; after three years, the weight you have lost will stay off — unless you go back to eating the way you did before. Similarly, eating a lot more food or a lot less over a short period of time will not affect your weight in the long run, as long as you average the same amount of calories from one year to the next.
All diets work, they say. But for lasting results, they take some time.

For postmenopausal women who are obese, breast cancer is more likely. That’s because fat tissue seems to behave essentially as an organ of the endocrine system, pumping out the hormone estrogen. And estrogen is a driver of many common breast cancers. But losing as little as 5% of one’s body weight — 10 pounds for a 200-pound woman — drives down levels of estrogen and other hormones that raise breast cancer risk, a new study finds.
In combination with weight loss, exercise drove down hormone levels even more, an effect that is likely to reduce a woman’s risk of developing breast cancer. But by itself, exercise did not have a significant impact on circulating hormones.
The more weight a woman lost, the greater the reduction in hormones linked to breast cancer risk.
While many studies have linked obesity to breast cancer, this is the first to show that losing weight will drive down that risk. Obesity is just one of many risk factors for breast cancer that a woman can do something about. Others include breastfeeding one’s babies, reducing alcohol consumption and steering clear of hormone-replacement therapy. Women at high risk of breast cancer are sometimes urged to consider taking one of several medications, including two first approved to prevent osteoporosis, to reduce their risk.
“This shows it’s never too late to make lifestyle changes to reduce your risk for breast cancer,” said co-author Dr. Anne McTiernan from Fred Hutchison Cancer Center.
While more significant weight loss drove down estrogen and other helper hormones more deeply, even a weight loss far short of what would be needed to exit the obese category helps a lot. The study’s authors estimate that a 5% loss of body weight would lower a woman’s breast cancer risk by 22%.
The study took 439 postmenopausal Seattle-area women who were sedentary and overweight or obese, and divided them into four groups. One group got an intensive weight-loss program focused on reducing calories and fat and choosing fruits, vegetables and high fiber; another group got an intensive exercise program only — five 45-minute aerobic exercise classes a week. A third group got a program that had exercise (mostly walking) and diet help. Members of the fourth group were asked not to change their diet or exercise habits but were offered four weight-loss classes and eight weeks of physical exercise training at the end of the study.
After a year, the average weight loss among the dieters was 10.8% of body weight, and among those who added exercise to their regimen, 11.9% (while the control group’s average weight inched up almost imperceptibly, the exercise-only group added 3.3% of body weight.)
The big changes were in levels of circulating hormones such as estradiol, estrone, testosterone and sex-hormone binding globulin, which takes estrogens out of circulation and is therefore protective against breast cancer. With diet, average levels of those hormones fell by 10% to 20%, and adding exercise generally subtracted as many as five percentage points from subjects’ hormone levels. The hike in SHBG — the breast-cancer protective agent — was 22.4% in dieters and 25.8% in those who did both diet and exercise.
The diet-and-exercise group also saw a decline in fasting insulin levels and measures of inflammation. The exercise-only group saw much smaller changes in all these measures — on the order of 5%.
The authors use hormone levels as a direct measure of increased or decreased breast cancer risk: they did not follow women to see who went on to develop breast cancer and who didn’t. Epidemiological studies have found that women who exercise regularly are less likely to get breast cancer. Acknowledging that, the authors suggested the exercise may help lower breast cancer risk by some means other than lowering estrogen levels.
