Now it seems that the notion that fat substitutes will keep fat off our bodies is a big fat lie. That, at least, is the suggestion of a study by Purdue University researchers that found that when rats consumed a fat substitute, signals that could help control food intake were disrupted, and the rats gained weight. The study gave laboratory rats crushed potato chips as a supplement to their diet, and divided the rats into two groups that were given either a low-fat chow diet or a high-fat chow diet. Wait, it gets more complicated: These groups were each split into two smaller groups. One group on each diet was fed a mixture of high-fat chips and the fat-substitute chips, containing olestra, which is a synthetic fat with no calories, while the other group received only regular high-fat chips. After four weeks, rats on the high-fat chow diet gained more weight and developed more fatty tissue when they were given fat-substitute chips compared to the animals that ate only regular high-fat chips. The researchers also found that when the rats that had previously consumed both fat substitute and high-fat chips were moved from a low-fat standard chow diet to a high-fat chow diet, they gained more weight.

    Another Troublesome Thing About Testosterone

    First, we learned that low testosterone can make us nicer people, or at least nicer male people. Now it looks like it can also spare us the frustration of prostate enlargement. Maybe. Researchers at the University of California at Santa Barbara are convinced that an overabundance of testosterone may be the dark force behind enlarged prostates. A UC Santa Barbara news release points out that benign prostatic hyperplasia (BPH) — or, simply, prostate enlargement — is one of the most common […]

    Is it safe to exercise if you experience atrial fibrillation, commonly known as irregular heartbeat?

HealthDay reports that after reviewing 14 studies involving 380,000 people with atrial fibrillation, the researchers are persuaded that moderate and vigorous levels of exercise are safe for women with atrial fibrillation but vigorous exercise may be risky […]

    Itchy eyes and sniffles no doubt seem insignificant to someone who’s pushing her body to run 26 miles, but researchers at Northumbria University are convinced that it’s a mistake for marathoners to ignore such symptoms. Why? Because, they warn, allergies that manifest themselves in itchy eyes and runny noses can lead to exercise induced asthma and inflammations of the airways. ScienceDaily reports on research involving 150 runners in the London marathon, 61 percent of whom reported nose and eye allergy […]

    “Ow, that hurts” apparently hurts less than just “that hurts,–” 20 percent less, to be precise. That’s the verdict from researchers at the National University of Singapore, where scientists asked 55 students to immerse one hand into ice-cold water. The students were then tested in five scenarios which included saying “ow”; sitting passively; pressing a button; listening to a recording of them saying “ow”; and listening to another person saying “ow”. The envelope please….The researchers found that participants who sat passively could […]
