Until recently, very few people had ever heard of raspberry ketones, the aromatic compounds that give the berries their distinctive smell. Today, health food stores have trouble keeping the capsules or drops of the stuff on their shelves. Almost overnight, an obscure plant compound became the next big thing in weight loss - and all it took was a few words from Dr. Oz. In a February episode of "The Dr. Oz Show," Mehmet Oz told viewers that raspberry ketones were "the No. 1 miracle in a bottle to burn your fat. " Once Oz calls something a "miracle," it doesn't remain obscure for long.

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.

In an age of long commutes, late sports practices, endless workdays and 24/7 television programming, the image of Mom hanging up her dish towel at 7 p.m. and declaring "the kitchen is closed" seems a quaint relic of an earlier era. It also harks back to a thinner America. And that may be no coincidence. A new study, conducted on mice, hints at an unexpected contributor to the nation's epidemic of obesity - and, if later human studies bear it out, a possible way to have our cake and eat it too, with less risk of weight gain and the diseases that come with it. Just eat your cake - or better yet, an apple - earlier.

Good form makes for a better workout, and that's one of the keys to ballet-inspired barre workouts. These exercises also increase flexibility and tone the muscles without adding bulk. Pasadena-based fitness expert, video host and teacher Tracey Mallett (www.traceymallett.com) is the founder of Booty Barre, a technique that combines elements of dance, yoga and Pilates to strengthen and stretch the body. No prior experience in any of those disciplines is necessary. Make sure the spine, neck and head are aligned and the movements are slow and deliberate.

Brian Price, once a wrecking ball on UCLA's defensive line, has beaten long odds to return to the NFL after two off-season surgeries aimed at keeping his hamstrings attached to his pelvis, rather than breaking loose and coiling down the backs of his thighs. For Price, who will start at defensive tackle Sunday for the Tampa Bay Buccaneers, his excruciating recovery was a 10-step process. Meaning just two months ago, he could run only 10 steps. "You have these doubts in your head at times," said Price, a second-round pick of the Buccaneers in 2010 who, because of his congenitally malformed pelvis, spent the last half of his rookie season on injured reserve.

Vertigo. For most people, the word summons images of Jimmy Stewart dangling from high places in Alfred Hitchcock's classic thriller by the same name. It means something else, however, to hundreds of thousands of people who experience the strange, dizzying affliction. The most common cause of vertigo, known as benign paroxysmal positional vertigo, usually can be treated with one visit to the doctor.

It was evidently good enough for Gilligan and Robinson Crusoe. But is coconut water a healthy choice for people who aren't stranded on a deserted island? A longstanding treat in tropical regions across the globe, coconut water hit U.S. supermarkets a few years back and is now being marketed with a vengeance. Sometimes billed as nature's sports drink, the slightly sour beverage has also acquired a reputation for being able to improve circulation, slow aging, fight viruses, boost immunity, and reduce the risk of cancer, heart disease and stroke.

"Oh, you mean the guy with the 70-year-old head and the 20-year-old body-builder body? That picture has got to be Photoshopped." Dr. Jeffry Life smiles when I tell him about the general reaction I get about the famous picture of him with his shirt off, the shot that turned a mild-mannered doctor in his mid-60s into a poster boy for super-fit aging and controversial hormone replacement Appearing in medical-clinic ads in airline magazines and...

When it comes to weight control, exercise doesn't matter. Non-exercise is what counts. That may sound like heresy, but, in fact, it's a theory based on years of highly respected research - and the science behind a little high-tech gizmo called the Gruve Solution. The Gruve is one of a gaggle of gadgets called personal activity monitors that you can carry in your pocket, hang on a keychain, wear like a watch. In this case, you "get your Gruve on" - as its maker, Gruve Technologies, likes to say - by attaching it to your waistband.

Gov. Jerry Brown is testy. He's defensive. He's very frustrated. He's only human, after all - not a demigod, not the all-wise, powerful supergov he portrayed himself to be when running for the office. It's hard to know who believed that portrayal the most: the voters, the Sacramento insiders or the candidate himself. Regardless, it hasn't panned out the way most people had hoped, and certainly not the way Brown had envisioned. So on Monday, he was in the governor's press conference room - built by his father, incidentally - trying to explain why the state budget hole had grown 71% deeper since January, expanding from $9.2 billion to $15.7 billion.

My mom's first day of motherhood was one of the happiest of her life. It was also one of the worst. She had accompanied my dad from Sri Lanka to Washington State University in 1968, so he could complete his doctorate as a Fulbright Scholar. The school was in Pullman, a small town near the Idaho border. Fluent in English, she worked as a university librarian. During her pregnancy, at age 30, she received care from one of Pullman's few obstetricians. She endured labor without drugs, and I was born healthy in 1972.

Don't forget to bring water to your workout, and not just to quench your thirst. Two water bottles are handy for this simple drill, demonstrated below by celebrity personal trainer Mike Donavanik (www.mikedfitness.com).

Just remember to keep your core tight through the entire drill and to not overreach when you pick up the bottle. Why you should try it: It's a great plyometric exercise that will work your legs, butt and core and improve hand-eye coordination.

Michael "Frosti" Zernow likes to vault, flip and catapult his way from A to B. The Santa Monica-based professional parkour athlete and instructor has 10-plus years of experience, and it shows: The man defies gravity when in motion, as you'll see if you check out the videos online. Parkour (or free-running) is a discipline that involves smoothly navigating obstacles like walls, stairs and trees with jumps, climbs and acrobatics. Zernow makes it look effortless, but it takes practice and discipline if you don't want to smack a wall.

In a new study examining diet, physical activity and obesity in prison populations, researchers at the University of Oxford in England have found that in most cases, male prisoners are less likely to be obese than men in the general population. Female prisoners, on the other hand, were more likely to be obese than other women - at least, in the U.S. and Australia. The findings, which were published Thursday in the journal Lancet (subscription required), reflect broader health disparities between advantaged and disadvantaged people, the researchers wrote.  They noted that in 2008, 36 million out of 57 million deaths worldwide resulted from non-communicable diseases such as heart disease, stroke, diabetes, cancer and respiratory disease.

Gloria Hale rose at 5:30 a.m. Tuesday, as usual, to swim laps before work. Active though she is, however, the 55-year-old Orange County woman was a bit stunned to learn the latest advice from researchers regarding exercise -- that women should work out 60 minutes a day, seven days a week, to maintain a normal weight over their lifetime. "Most people are going to say, 'No way. I don't have time for that,' " said Hale, a trim 5-foot-5 and 138 pounds. The 60-minute-a-day recommendation, released online Tuesday in the Journal of the American Medical Assn.

What are the advantages and disadvantages of using the supplement nitric oxide? Richard Sunland Nitric oxide is a gas naturally found in the body; its function is conveying information between cells. One of its main jobs is increasing blood flow by dilating blood vessels, and that's why it's sometimes given in supplement form to heart patients, orally and intravenously. In at least one study it's been shown to be effective for lowering blood pressure.

Even if you're 80 or older, it's not too late for daily exercise to reduce your risk of developing Alzheimer's disease, according to a new study. And if hitting the gym isn't quite your style, here's more good news: You can also benefit by doing housework, researchers say. Plenty of research has suggested that people who make a habit of exercising are less likely to get Alzheimer's, though scientists aren't sure how to explain the link. Other activities that have been correlated with a reduced risk for Alzheimer's include engaging one's brain in mentally stimulating activities, spending time in social groups and eating a healthful diet, according to the National Institute on Aging . The new study , published in the journal Neurology, involved 716 people who were part of the Memory and Aging Project at Rush University Medical Center in Chicago.

Toward the end of Cheryl Strayed's memoir, "Wild," the author, who is in the middle of hiking 1,100 miles alone across the West Coast's formidable Pacific Crest Trail, loses one of her hiking boots. She stands at the edge of a precipice and gasps. But the moment has passed and the shoe is gone. "The universe, I'd learned, was never, ever kidding," she writes. "It would take whatever it wanted and never give it back. I really did have only one boot. " This line about the universe could be the catchphrase for the book itself, which pivots with unflinching honesty around the author's loss of her mother to lung cancer when Strayed was 22. This crushing blow leaves Strayed unmoored as her family splinters apart without its matriarch.
