No-Diet Ways to Lose Weight
If sifting through the Google results for “diets that work” makes your head spin, try this trick: Don’t call it a diet. “For most Americans, diet is a dirty word that evokes pain, frustration, and bad memories of diets that went belly up,” says Connie Bennett, a life and health coach and author of Sugar Shock: How Sweets and Simple Carbs Can Derail Your Life—and How You Can Get Back on Track. So forget trying to overhaul your eating with detox cleanses and flavorless microwave meals. Instead, focus on making small, manageable changes that fit into your life. The following 11 simple strategies will help you slim down without giving up what you love.
1) Schedule Sweat Sessions. It’s obvious advice, but it works. Exercise can help you lose weight by burning calories, increasing metabolism, and warding off cravings. Italian researchers found that overweight, sedentary women who made no changes to their eating habits but participated in a 12-week indoor cycling program of three 1-hour sessions per week reported weight loss, fat loss, smaller waist sizes, and increased muscle mass after 24 and 36 sessions. The women also lowered their resting and training heart rates and improved cardio-respiratory fitness, according to a study published in the Journal of Sports Medicine and Physical Fitness.

2) Pick Petite Plates. “If you can decrease the amount of food you currently eat by 25 percent, you would quickly see the pounds come off,” says Adam Shafran, cohost of the Atlanta-based radio show Dr. Fitness and the Fat Guy and coauthor of 35 Things to Know to Raise Active Kids. “Try using smaller plates and taller glasses in order to give the appearance of bigger portions.” When you’ve finished eating, leave your dainty dinnerware where you can see it. Sitting among heaps of dirty dishes helped Cornell University graduate students eat 28 percent less than those whose tables were cleared at a free Super Bowl Sunday chicken wing buffet, according to a study published in the journal Perceptual and Motor Skills.
3) Take Time-outs. To keep your body moving—and burning calories—throughout the day, Bennett suggests taking a mini break every 15 minutes. “It reminds me to stretch, take care of my back, do some exercise bursts, be present, and have fun,” says Bennett. “You can take as little as 30 seconds or as long as 5 minutes. Just get up off your rear end, stretch, go get some water, pull in your stomach, rearrange something on your desk or in your home, and stand on your tippy toes.” To schedule your breaks, try setting a timer. This free tool from online-stopwatch.com lets you pick your own sound—like a round of applause—to signal that it’s time to get up and move.
4) Don’t Skimp on Sleep. “Sleep deprivation causes fatigue, clumsiness, and weight gain,” says Carrie Wiatt, owner of Diet Designs, a Los Angeles–based nutritional counseling firm. “Getting enough sleep is crucial to proper cognitive function as well as controlling hunger.” Sleep deprivation has the power to slow down your metabolism, increase your appetite, and throw your body’s hunger and satiety hormones out of whack. Of more than 68,000 middle–age women who participated in a Case Western Reserve University study, those who slept for less than 5 hours each night were 32 percent more likely to gain 33 pounds or more over the course of the 16-year study, compared with those who got 7 to 9 hours of shut-eye.
5) When in Doubt, Delay. Here’s one way procrastination can work in your favor. “If carb cravings are haunting you, just delay,” Bennett suggests. “In other words, look at your watch and promise yourself that for the next 10 to 15 minutes, you won’t give in to your cravings. During that time, you could go to the restroom, wash the dishes, or call a friend.” You’ll give yourself a chance to figure out what your body really wants or needs—maybe a glass or water, a protein-rich snack, an energizing walk, or even a laugh.

Tiny breaks from sitting can whittle a tinier waist
Taking short breaks from sitting, even for only one minute, might whittle your waistline and improve your heart health, according to a new study.
People in the study who took the most breaks from sitting — up to 1,258 short breaks in one week — were about two pant sizes smaller than those who took the fewest, as few as 99 breaks in one week, said study researcher Genevieve Healy, who studies population health at the University of Queensland in Australia.
And a smaller waistline means less abdominal fat and better heart health, Healy said.
"A high waist circumference is associated with an increased risk for type 2 diabetes, high blood pressure and cardiovascular disease," she told MyHealthNewsDaily.
When we stand, the large muscles in our legs and the back are continually contracting to maintain our posture, but when we sit or recline, these muscle groups are basically inactive, Healy said.
"So even short breaks from sitting get these large muscle groups contracting," she said.
The study will be published tomorrow (Jan. 12) in the European Heart Journal.

Swine flu could mix with bird flu, expert warns
Bird flu kills more than 60 percent of its human victims, but doesn't easily pass from person to person. Swine flu can be spread with a sneeze or handshake, but kills only a small fraction of the people it infects.
So what happens if they mix?
This is the scenario that has some scientists worried: The two viruses meet — possibly in Asia, where bird flu is endemic — and combine into a new bug that is both highly contagious and lethal and can spread around the world.
Scientists are unsure how likely this possibility is, but note that the new swine flu strain — a never-before-seen mixture of pig, human and bird viruses — has shown itself to be especially adept at snatching evolutionarily advantageous genetic material from other flu viruses.
"This particular virus seems to have this unique ability to pick up other genes," said leading virologist Dr. Robert Webster, whose team discovered an ancestor of the current flu virus at a North Carolina pig farm in 1998.
The current swine flu strain — known as H1N1 — has sickened more than 2,300 people in 24 countries. While people can catch bird flu from birds, the bird flu virus — H5N1 — does not easily jump from person to person. It has killed at least 258 people worldwide since it began to ravage poultry stocks in Asia in late 2003.
"Do not drop the ball in monitoring H5N1," WHO Director-General Margaret Chan told a meeting of Asia's top health officials in Bangkok on Friday by video link. "We have no idea how H5N1 will behave under the pressure of a pandemic."
Experts have long feared that bird flu could mutate into a form that spreads easily among people. The past three flu pandemics — the 1918 Spanish flu, the 1957-58 Asian flu and the Hong Kong flu of 1968-69 — were all linked to birds, though some scientists believe pigs also played a role in 1918.
Webster, who works at St. Jude's Children's Research Hospital in Memphis, Tenn., said bird flu should be a worry now. Bird flu is endemic in parts of Asia and Africa, and cases of swine flu have already been confirmed in South Korea and Hong Kong.
"My great worry is that when this H1N1 virus gets into the epicenters for H5N1 in Indonesia, Egypt and China, we may have real problems," he told The Associated Press. "We have to watch what's going on very diligently now."
Spokesman Dave Daigle said he could not comment specifically on how concerned the U.S. Centers for Disease Control and Prevention is about the scenario Webster describes, or what it is doing to study such a possibility.
Malik Peiris, a flu expert at Hong Kong University, said the more immediate worry is that swine flu will mix with regular flu viruses, as flu season begins in the Southern Hemisphere. It is unclear what such a combination would produce.
But he said there are indications that scenario is possible. Peiris noted that the swine flu virus jumped from a farmworker in Canada and infected about 220 pigs. The worker and the pigs recovered, but the incident showed how easily the virus can leap to a different species.
"It will get passed back to pigs and then probably go from pigs to humans," Peiris said. "So there would be opportunities for further reassortments to occur with viruses in pigs."
He said so far bird flu hasn't established itself in pigs — but that could change.
"H5N1 itself has not got established in pigs," he said. "If that were to happen and then these two viruses were both established in pigs in Asia, that would be quite a worrying scenario."
"Everything with influenza is a huge guessing game because Mother Nature holds all the rules, and we don't even know what they are, so anything's possible," he said. "We don't have any evidence that this particular reassortment is that much more likely to pick up H5N1 than any other reassortment out there."
"We don't have to put these things together," he added. "This is not chocolate and peanut butter running into each other in the dark hallway."
But there is in fact discussion of putting them together — in a high-security laboratory — to see what a combination would look like, according to Webster. Similar tests have been done at the CDC mixing bird flu and seasonal human flu, resulting in a weak product, he said.
Daigle, the CDC spokesman, refused to comment on the prospect of any such experiment.
Webster has done groundbreaking work on both swine and bird flus in his 40-year career, and has followed the evolution of the current swine flu strain from a virus that sickened a handful of people who worked with North Carolina hogs into a bug that has spread from person to person around the world.
He is closely involved in the global effort to analyze what the virus might do next. It has killed 42 people in Mexico and two in Texas, but so far has not proven very deadly elsewhere, leading to some criticism that the World Health Organization's warnings of a potential pandemic have been overblown.
Webster said underestimating the swine flu virus would be a huge mistake.
"This H1N1 hasn't been overblown. It's a puppy, it's an infant, and it's growing," he said. "This virus has got the whole human population in the world to breed in — it's just happened. What we have to do is to watch it, and it may become a wimp and disappear, or it may become nasty."

Pregnant women often deny smoking
Overall, about one in four women who smoke while pregnant deny it, a new study hints. The numbers could be even higher in certain groups of women, like those in their early 20s.
In the United States, smoking by moms-to-be is one of the most common preventable causes of illness and death among infants, Dr. Patricia Dietz from the division of reproductive health at the Centers for Disease Control and Prevention in Atlanta, and colleagues note in their report.
In their study, they estimated how many pregnant and nonpregnant smokers aged 20 to 44 years did not disclose their habit on a health questionnaire.
How did they catch the deception? They took blood samples from the women to measure levels of cotinine -- a byproduct of nicotine that serves as a marker of exposure to tobacco smoke. Their analysis included 994 pregnant women and 3,203 nonpregnant women.
Overall, 13 percent of pregnant women and 30 percent of nonpregnant women were active cigarette smokers. The pregnant smokers smoked an average of 11 cigarettes a day, while the nonpregnant smokers averaged close to 14 cigarettes a day.
According to the investigators, far more pregnant than nonpregnant smokers failed to disclose their habit - 23 percent versus nine percent - and were identified by their cotinine concentrations.
For a variety of reasons, such as the fact that pregnant women's bodies break down cotinine faster, the researchers think the results "likely underestimate" the true number of pregnant women who smoke and don't say so.
Among both pregnant and nonpregnant smokers, those most likely to keep this information to themselves were women aged 20 to 24, as well as those with Medicaid or other source of government-funded health insurance and those with less than a high school education.
Race also factored in. Pregnant smokers who failed to report their habit were most likely to be non-Hispanic black. In women who weren't pregnant, nondisclosure was most common among Mexican-American women and non-Hispanic blacks.
Writing in the American Journal of Epidemiology, Dietz and her colleagues say their findings may have important implications for researchers studying how smoking during pregnancy affects the developing baby, as roughly one in four pregnant smokers, and one in 10 nonpregnant smokers, deny smoking.
Studies and surveillance systems that rely on people to accurately state their smoking status may get inaccurate information, "especially among pregnant women," they warn.
