The More You Run, The Less You Eat. Go Figure

January 21, 2013 9:09 am 0 comments

Exerciimagesse, which burns calories, should make you hungry, right? Not exactly. Writing in the New York Times, Gretchen Reynolds explains that exercise does in fact, boost the production of ghrelin, a hormone that tell us that we want food. But wait, here comes the strange part. Reynolds cites a 2012 study from the University of Wyoming, for which a group of women either ran or walked and, on alternate days, sat quietly for an hour. Yes, the researchers found that those who ran produced more ghrelin, but the same group also ate fewer calories than they burned. Why? Because, the researchers believe, exercise also boosts the production of other less understood hormones that tell the body that it doesn’t really need more food. Reyolds cites a second study published in December that found that after 12 weeks of jogging, formerly sedentary, overweight men and women began recognizing, without consciously knowing it, that they should not overeat. Reynolds quotes Catia Martins, study author and a professor at the Norwegian University of Science and Technology in Trondheim, saying exercise “improves the body’s ability to judge the amount of calories consumed and to adjust for that afterward.” Running, says Martins, does that better than walking, and the longer you do it, the more better it works.

    No, not marijuana. The researchers at the University of Washington were looking at drugs like Benadryl, anti-depressants like Sinequan, anti-histamines like Chlor-Trimeton, and antimuscarinics for bladder control like Ditropan.  A university news release reports that the scientists, who tracked nearly 3,500 Group Health seniors participating in a long-running joint Group Health-UW study funded by the National Institute on Aging, found that such drugs, with anticholinergic effects, significantly increased risk for developing dementia, including Alzheimer’s disease, in people who took them for longer […]

    Research Suggests That Exercise Cuts Breast Cancer Risk

    Can exercise really help to ward off breast cancer? Researchers at the University of New Mexico in Albuquerque think so. The Wall Street Journal, reports that scientists at the school have been studying the cancer fighting effects of irisin, a hormone that is released from muscles after vigorous exercise. When the researchers tested genetically engineered irisin on aggressive breast-cancer cells and on nonmalignant breast cells, they found that irisin treatment reduced the number of malignant cells by 34 percent compared with untreated cells, […]

    The Beet Juice Conundrum: Does It Boost Blood Flow?

    For years, athletes have been drinking beet juice before working out to increase blood flow to muscles and boost performance. Now comes a study from researchers at Penn State suggesting that the beet juice strategy was all for naught. A Penn State news release reports that while beetroot juice is in fact rich in nitrates, it did not enhance muscle blood flow or vascular dilation during exercise. The good news, although not necessarily for athletes, is that the researchers found that […]

This study, a meta-analysis of others, comes from scientists at Toronto’s University Health Network (UHN) and Institute for Clinical Evaluative Sciences, and like others, identifies a definite relationship between the amount of time a person sits everyday and heart disease, cancer, diabetes, and death. Wait, there’s more unsurprising news.  Science Daily reports that study found that the […]

HealthDay reports that scientists at the institute put 29 people in casts that completely immobilized their hand and wrist for four weeks. Fourteen of those people were told to routinely perform an imagery exercise, imagining that they were intensely contracting their wrist for five seconds with five seconds of rest. Wait, there’s more: As they performed this imagery exercise, they were […]

    Some wives’ tales turn out to be true. Maybe. A Yale University news release reports that researchers at the school are convinced that the common cold virus can reproduce itself more efficiently in the cooler temperature found inside the nose than at core body temperature, suggesting that there is truth to the popular notion that people are more likely to catch a cold in cool-weather conditions. The researchers examined cells taken from the airways of mice, and compared the immune response to […]
