Want to know how to walk off the calories from a Thanksgiving dinner? Keep walking. About 18 hours after you start, you’ll be back to ground zero. According to this calories burned chart, walking burns about 250 calories an hour. And according to this Thanksgiving calorie counter, a Thanksgiving meal delivers 4,575 calories. The math is simple, the journey is not. Here’s some more math: if you walk at a normal pace of 3.5 miles per hour for 18 hours, you’ll cover 63 miles.

To Impress Women, Men Eat

November 23, 2015 8:31 am 0 comments

It dq-menu-food_single_cheeseburger_02may not be the most elegant way to show off, but elegance rarely gets in the way a man on the make. Researchers at Cornell University are convinced that men eat more, a lot more, when women are seated at their table. Why? That’s a tough one, but the researchers theorize that men may overeat to highlight their fitness through excessive, risky eating behaviors. They say this type of risky activity is meant to show females how tough and strong a man might be in the face of challenges. OK. Maybe. HealthDay reports on the research, for which scientists secretly observed 105 adults having their lunches at an all-you-can-eat Italian buffet over the course of two weeks. Ready, the envelope please….Men who dined with at least one woman ate 93 percent more pizza and 86 percent more salad than those who ate only with men. And the women? They ate the same amount of foods, whether they dined with women or men.

Researchers Say Once A Week Is The Magic Number

Yes, we’re talking about sex. We’re also tcopy2-1362920805-0004alking about academic research, in this case at the University of Toronto Mississauga, where scientists have determined that sex is good, and more sex is better. But how much is just right? HealthDay reports that the Canadian researchers studied the results from a survey conducted in the United States every other year between 1989 and 2012, focusing on responses from more than 25,000 people, aged 18 to 89. Among other things, participants answered questions about sexual frequency (from not at all to four or more times a week) and their perceptions of their happiness. Ready? The envelope please….The researchers found that couples who had more sex were happier, but well-being leveled off once couples reached a frequency of about once a week. Note well: people who had sex more than once a week were not less happy, they just didn’t get happier with more sex. They just had more sex.


Three Cups Of Coffee Lowers Death Risk

November 17, 2015 8:12 am 2 comments

Three to five cups of coffee imgresa day won’t just keep you from falling asleep at work, it may save you from premature death. That’s the suggestion of a recent study by researchers at Harvard’s Chan School of Public Health. A Chan School news release reports that the researchers analyzed health data gathered from three large ongoing studies: 74,890 women in the Nurses’ Health Study; 93,054 women in the Nurses’ Health Study 2; and 40,557 men in the Health Professionals Follow-up Study. Ready, the envelope please…The researchers found that moderate coffee consumption was associated with reduced risk of death from cardiovascular disease, diabetes, neurological diseases such as Parkinson’s disease, and suicide. There was no association with cancer.

Low Vitamin D and ED, Maybe

November 16, 2015 8:29 am 1 comment

imagesIs vitamin D related to ED, as in erectile dysfunction? Researchers at Johns Hopkins Med School think it may be. HealthDay reports that when scientists at the school analyzed data from more than 3,400 men, age 20 and older, they found that vitamin D deficiency was present in 35 percent of men with erectile dysfunction, compared with 29 percent of those without erectile dysfunction. That means that men with vitamin D deficiency were 32 percent more likely to be impotent than those with sufficient vitamin D levels, and that association held even after accounting for other factors associated with erectile dysfunction, such as drinking, smoking, diabetes, higher blood pressure, inflammation and certain medications. How big a problem is that? The researchers claim that about 40 percent of men older than 40 and 70 percent of those older than 70 are unable to attain and maintain an erection.

High-Intensity Training Best For Endurance

November 13, 2015 8:52 am 1 comment

It seems counterintuitive, but short bursts of high-intensity training appear to do more for endurance than running a marathon does. The Wall Street Journalimages reports on the research supporting the claim, which was conducted at the Karolinska Institute in Stockholm, where researchers asked 50 men to cycle as fast as possible for 30 seconds, rest for four minutes and then repeat the exercise six times. They then collected muscle tissue samples from the cyclists’ thighs, and looked for evidence of free radicals that break down calcium channels in the muscle cells and tell cells to increase their muscular endurance by boosting the production of mitochondria. Ready? The envelope please…..The Journal reports that the researchers found that when compared to the muscle cells of people who had recently run marathons, the cells of high-intensity exercisers showed a bigger effect on their calcium channels than running 26 miles. Why? Because a normal workout may release 20 percent-30 percent more free radicals, high-intensity exercise can release upward of 200 percent more free radicals. The bottom line: add high-intensity workouts to training regimes to boost stamina.

The Leg Strength/Brain Strength Link

In healthy women at least, theCachedImagere appears to be a link between leg strength and brain activity. A news release from King’s College in London reports that researchers at the school have found that leg strength was a better predictor of brain health than any other lifestyle factor looked at in a recent study, which involved 324 healthy female twins, aged 43 to 73. The researchers measured thinking, learning and memory at both the beginning and end of the study. Generally, the twin who had more leg power at the start of the study sustained their cognition better and had fewer brain changes associated with aging measured after ten years.

Energy Drinks Light Up Stress Hormone

November 10, 2015 7:57 am 2 comments

Just one energy drink is enough to seriously boost the fight-or-flight hormone norepinephrine, even imgresin young healthy adults. Yikes! HealthDay reports that researchers at the Mayo Clinic gave 25 healthy adults between the ages of 26 and 31 either a 16-ounce can of Rockstar Punched or the sham drink in random order on two separate days. The researchers then measured participants’ blood pressure and blood levels of norepinephrine before and 30 minutes after they chugged each drink. Ready? The envelope please….the researchers found that Rockstar Punched elevated blood levels of the “fight-or-flight” hormone norepinephrine 74 percent, compared with a 30 percent increase in those who consumed a fake energy drink.

Fat? Study Says It’s Not The Junk Food

November 9, 2015 8:12 am 1 comment

imgresAre you sitting down? A new study from researchers at Cornell claims that for all but the most overweight and underweight people, the consumption of soda, candy and fast food showed no correlation to BMI. A Cornell news release reports that the findings upend the seemingly self-evident conclusion that consuming unhealthy foods is the cause of high rates of obesity. According to researcher David Just, previous studies reporting a positive correlation between indulgent foods and weight status at the population level failed to take into account the distorting effects from the roughly five percent of people who are either chronically underweight or morbidly obese. For the rest of the 95 percent of the population, the consumption of those indulgent foods and beverages showed no significant difference between the habits of healthy weight and overweight individuals. “Simply put, just because those things can lead you to get fat doesn’t mean that’s what is making us fat,” says Just. “By targeting just these vilified foods, we are creating policies that are not just highly ineffective, but may be self-defeating as it distracts from the real underlying causes of obesity.” The study blames the increasing rates of obesity on “other things,” like the likelihood that you’re sitting down while reading this.

Extreme Exercise Could Be Bad For Your Heart

November 6, 2015 8:00 am 3 comments

imagesExtreme exercise, such as running more than 35 miles a week or biking more than 150 kilometers a week, could increase levels of coronary artery calcium–a bad thing. The Wall Street Journal reports on a recent study conducted by British physicians that looked at the cardiac health of 169 serious endurance athletes. Forty-one men and 16 women in the group ran more than 35 miles or cycled more than 150 kilometers a week. The researchers found that, compared with the control group, athletes who ran fewer than 35 miles a week or cycled fewer than 150 kilometers a week had lower levels of coronary artery calcium. But athletes who ran or cycled beyond that threshold had higher levels of coronary artery calcium than did the control group. Wait, there’s more. Intensity of exercise also appeared to influence coronary artery calcium. The Journal reports that, compared with the control group, there were significantly lower levels of coronary calcium in the slowest men and women. In women, those levels rose as speed increased, though not to the levels of the relatively sedentary control group. The fastest men, however, had significantly higher levels of coronary calcium than did men in the control group.
