Health Tip: Healthy Fats? They Exist

Here are some common sources

(HealthDay News) — All fats shouldn’t be treated equal. Your body craves certain “healthy” fats, which are unsaturated fats mostly found in plant-based foods.

The womenshealth.gov website says these foods are good sources of “healthy” fats:

  • Olive, canola and peanut oils.
  • Most types of nuts.
  • Avocados.
  • Safflower and sunflower oils.
  • Corn oil, soybean oil and cottonseed oil.
  • Fatty fish, such as salmon, mackerel and trout, as well as flaxseed, all of which are good sources of omega-3 fatty acids.

Health Tip: Food Can Affect Sleep

What you eat and drink can keep you up or make you drows

(HealthDay News) — What you eat and drink can have a big impact on your ability to fall or stay asleep. Many foods can make you feel drowsy, while others can cause trouble sleeping.

The National Sleep Foundation mentions these examples of foods and beverages that can affect your sleep:

  • Carbohydrate-laden foods make it easier for a sleep-inducing amino acid called tryptophan to reach the brain. Tryptophan is found in many protein rich-foods. So combining proteins and carbs makes for good pre-bedtime snacks. Examples include milk and cereal, cheese and crackers or peanut butter and toast.
  • Eating a big meal also can trigger sleepiness, particularly when it’s heavy in carbohydrates.
  • Caffeine in the late afternoon or before bedtime can inhibit drowsiness, but can lead to trouble sleeping.
  • Energy drinks may temporarily boost energy levels, but they often cause a crash and ultimately can lead to drowsiness.
  • Alcohol can cause disruptions in sleep and inhibit entering the deep stages of sleep.

How to Keep From Overeating When Eating Out

Try ordering a la carte and skipping foods that aren’t your favorites, study says.

By Jenifer Goodwin
HealthDay Reporter

TUESDAY, Jan. 10 (HealthDay News) — It’s easy to overeat at restaurants. But researchers from University of Texas at Austin say they’ve come up with a strategy that helped a group of middle-aged women who eat out frequently avoid gaining weight and even lose a few pounds.

Calling it “Mindful Restaurant Eating,” researchers taught the women to pay close attention to what they were eating and how they were feeling, with the goal of being satisfied with smaller portions and putting down their forks before they felt overly full.

“Going out to eat has become a major part of our culture. Frequently eating out and consuming high-calorie foods in large portions at restaurants can contribute to excess calorie intake and weight gain,” said study lead author Gayle Timmerman, an associate professor of nursing. “But just saying, ‘Don’t eat out’ isn’t feasible.”

Nor is just telling people to eat only the low-cal options. “You can’t just say, ‘Choose the steamed vegetables.’ People aren’t going out to eat for steamed vegetables. They’re going out to eat for something they’re not getting a home.”

So people need strategies to help avoid excess calories when they do eat out, while still being able to enjoy the experience.

The study, published in the January/February issue of the Journal of Nutrition Education and Behavior, included 35 women, aged 40 to 59, who were mostly overweight or obese and ate out at least three times a week. Eating out included any meal — breakfast, lunch, or dinner — or even getting a pastry and a latte at Starbucks.

About half the women attended six weekly, two-hour group sessions that focused on reducing calories and fat intake when dining out, while the other half were wait-listed. The sessions covered the basics of nutrition, portion size and information about the calories and fat content of foods.

But the women also got into specific strategies to use when dining out, such as what are the least fattening foods to order when eating at a Mexican or Italian restaurant.

Among the tips:

  • When you order, request a “to-go box” delivered along with the meal, then slide half of the meal into it before you even start eating. “Research shows when you have less on your plate you eat more slowly, and that helps you feel fuller,” Timmerman said. “If you wait to put the food in the to-go box, you tend to encroach. Then you say, ‘Well, I don’t want to waste it.’ ” Before you know it, you’ve got a clean plate.
  • Order a la carte. If you don’t really want three tacos, rice and beans, pick and choose. Perhaps just order two tacos and call it a day. Also, “ask for gravy, butter and dressing on the side to make sure you’re not getting calories you didn’t intend or you didn’t even necessarily want,” Timmerman said.
  • If you can take it or leave it, leave it. “I like focusing on choosing ‘loved’ calories, and avoiding ‘unloved’ calories,” Timmerman said. “Eat the foods you love, and skip foods you feel neutral about. I’m neutral about rice, so when I eat out, I ask them to not even bring the rice. A lot of time we are eating the ‘unloved’ calories, we’re not particularly enjoying them and we don’t even really want them.” The exception, she added, are foods that are highly nutritious. You may be neutral about broccoli, but eat it anyway.
  • Share. Split a main course, a basket of fries or dessert.
  • Be mindful about what you’re eating and savor each bite. “Let’s say you get those fries,” Timmerman said. “Eat each one slowly and pay attention to the enjoyment you’re getting out of the texture, the smell, the taste. Then you can ask, ‘Do I really need to eat a whole basket of them in order to be satisfied, or can I eat a handful?’ Focus on the pleasure you’re getting from them.”
  • Focus on how you feel. It takes the body about 20 minutes to figure out that you’re full, and research has shown that eating more slowly can prevent over-eating by allowing the brain that time to register feelings of satiety. Even chewing food more can help you slow down and feel more full, Timmerman said.
  • At a Chinese restaurant, choosing steamed over fried rice can save 100 calories or so. At a steak place, sirloin is one of the leanest cuts of beef. When eating Italian, marinara or clam sauce is a better choice than creamy alfredos. And eggplant parmesan? Don’t let the vegetable fool you. Eggplant soaks up oil and is often a very high-calorie dish. When eating pizza, sausage and pepperoni pack on the calories. A veggie pizza is, of course, a good choice, but if you can’t stand broccoli and mushrooms on your pie, even Canadian bacon is lower in calories than other meats.

For the women in the study, such techniques seemed to work. Although the intent of the study was only to prevent them from gaining weight, after six weeks, they’d actually lost an average of about 3 to 4 pounds. Food diaries showed they were also eating about 300 fewer calories daily.

That’s great news, said Joy Dubost, a registered dietician and spokesperson for the Academy of Nutrition and Dietetics.

“Sometimes you hear in the media, or even dieticians may advise, ‘If you want to lose weight, don’t eat out. But you can eat out and enjoy it and with this program lose weight,” she said.

The women’s food diaries showed that they were also consuming fewer calories at home, so the weight loss was probably a result of an overall shift in eating habits, not just when they were dining out, Dubost added.

For anyone trying similar techniques, one of the keys is planning ahead on food choices before you get to the restaurant. And try researching nutritional content on restaurant websites, Timmerman said.

“You have to have a plan going in,” Timmerman said. “It’s too easy to consume extra calories, not even intentionally. In the food environment we have now, we can’t afford to not pay attention. We will gain weight.”

Prior research has shown people eat about 230 extra calories on days they eat out, Timmerman said.

John E. Lewis, an associate professor of psychiatry and behavioral sciences at the University of Miami School of Medicine, said targeting the social, emotional and mental aspects of overeating makes sense.

“Mindfulness is something that is gaining in popularity for a lot of health conditions, and particularly for people who need to lose weight,” he said.

And yet, people should still be reminded that too much eating out — whether at fast-food or restaurants with massive portions — is part of the problem, he said. Cooking healthy meals at home is still your best choice for the majority of your diet, he said.

Health Tip: Set an Exercise Schedule

To help adhere to your fitness routine

(HealthDay News) — Adhering to an exercise routine can be a challenge, but creating a schedule can help you stay on track.

The American Academy of Orthopaedic Surgeons suggests how to create a workout schedule:

  • Create a weekly schedule that includes time off.
  • Start out by scheduling moderate-intensity exercise of about 30 minutes per session, including a variety of activities from walking to gardening.
  • Consider scheduling shorter intervals at first, such as by allocating two 15-minute workouts per day instead of one 30-minute block.
  • Avoid skipping a workout in the beginning if you feel sore, unless you feel severe pain or notice any swelling.
  • Schedule workouts in the time of day that’s most comfortable. Avoid exercising just after a meal or outdoors when it’s too hot or too cold.
  • Wear comfortable, supportive shoes that fit well.

Persistence Is Key to Losing Weight and Keeping It Off

Mastering any new skill, including eating right and exercising, takes practice, expert says 

 

 

SUNDAY, Jan. 1 (HealthDay News) — Losing weight is one of the most common New Year’s resolutions, but changing long-held behaviors is a skill in itself, a medical expert says.

To shed unwanted pounds and keep them off, people have to be ready to face some setbacks and keep on trying, said Dr. Jessica Bartfield, an internal medicine and medical weight-loss specialist at Gottlieb Memorial Hospital, part of the Loyola University Health System.

“People need a motivation to lose weight and the new year is an opportunity to start fresh,” Bartfield said in a Loyola news release. “Behavior change is the cornerstone of healthy, successful weight loss and it takes about three months to establish a new behavior,” she pointed out.

“When you learn to ride a bike, you expect that you will fall down a couple times and are prepared to try again and get back on; you need to have the same expectation with weight loss and to plan accordingly,” she explained.

Only 20 percent of Americans who’ve tried to lose weight will keep the weight off after one year, according to the U.S. Centers for Disease Control and Prevention. Bartfield offered the following tips to help reverse this trend and help people achieve and maintain their weight-loss goals:

  • Don’t skip breakfast. “Eating within one hour of awakening can boost your metabolism up to 20 percent for the rest of the day,” Bartfield said. “Eating something is better than eating nothing, but ideally try to incorporate protein for longer-lasting fuel.”
  • Have a weekly weight check. “Monitoring your weight on a weekly basis provides a fairly accurate weight trend and, more importantly, an early detection of any weight regain, which allows you to adjust behaviors accordingly,” Bartfield said.
  • Exercise for one hour every day. “Snow shoveling, vacuuming, taking the stairs — you don’t have to run like a hamster on a wheel for 60 minutes. Take three 20-minute brisk walks, or compile the one hour based on a series of activities,” she advised.
  • Limit TV to fewer than 10 hours each week. “Many argue they don’t have time to exercise, but when I ask them to count the hours they spend watching TV or surfing the Net, they are able to find the time for activities where they are moving instead of sitting,” Bartfield said.
  • Keep track of your physical activity. “Park your car farther away, take the stairs, manually change TV channels — these are all simple ways to get more physical activity and you need to write them down as they are performed to keep yourself honest,” Bartfield said. “Also wearing a pedometer can help accurately document and track your progress.”
  • Keep track of calories. Do not underestimate how many calories you consume at each meal.
  • Set clear, realistic goals. Avoid setting vague goals. Objectives need to be specific and attainable. People can start by trying to lose 10 percent of their body weight, Bartfield recommended.
  • Be consistent. “Eat at regular intervals seven days per week,” Bartfield advised. “Being ‘good’ on the weekdays and then splurging on the weekend creates a harmful cycle that discourages weight loss.”
  • Plan for setbacks. “When you learn to drive, or learn a sport or musical instrument, you make mistakes and you have an experienced instructor — maybe even several — to help correct the mistakes and prevent repeats. Enlist a trusted friend, or enroll in a program to learn and master the rules of weight loss,” Bartfield said.

When it comes to teenagers who need to lose weight, parents should get involved. “Treating child and adolescent obesity needs to be a family effort; families need to change behaviors,” she said. “Research shows that families — and even couples — who change behavior together are the most successful.”

More Exercise Could Make For Better Sleep: Study

Those getting 150 minutes’ activity a week were less likely to report daytime fatigue.

By Randy Dotinga
HealthDay Reporter

  

THURSDAY, Dec. 1 (HealthDay News) — A new study suggests regular physical activity might encourage better shut-eye: People who met national exercise guidelines reported better sleep and less daytime fatigue than those who didn’t.

The research doesn’t confirm that exercise directly leads to improved rest, and it’s possible there may be another explanation for the apparent connection between exercise and sleep. Still, the findings are mostly consistent with previous research, said Matthew P. Buman, an assistant professor of exercise and wellness at Arizona State University who’s familiar with the study.

But if you think a daily walk or jog will clear up your sleep problems, that might be a bit too optimistic.

“In general, the relationship between physical activity and sleep is moderate,” Buman said.

More than one-third of U.S. adults have trouble falling asleep at night or staying alert during the day, according to background information in the study. Inadequate sleep has been linked to depression, cardiovascular disease and other health problems.

The new study, led by researchers at Oregon State University, looked at statistics from a U.S. health survey conducted from 2005 to 2006. The researchers focused on more than 2,600 men and women — aged 18 to 85 — who measured their activity levels and answered questions about sleep.

All wore accelerometers, devices that measure physical activity, for a week.

The researchers adjusted their statistics so they wouldn’t be thrown off by unusually high or low numbers of people of certain ages, weight, health condition, smoking history or other factors.

The researchers then determined how many participants met or exceeded national exercise guidelines by getting at least 150 minutes a week of moderate exercise or 75 minutes a week of vigorous exercise or a combination of both.

Those who met the guidelines were 65 percent less likely to report often feeling sleepy during the day compared to those who got less exercise. They were also 68 percent less likely to report sometimes having leg cramps and 45 percent less likely to report having trouble concentrating while tired.

The study appears in the December issue of the journal Mental Health and Physical Activity.

Buman called the finding intriguing, even if it doesn’t prove that exercise improves sleep.

If that is the case, however, the causes are unclear. Some researchers think physical activity improves sleep by helping reduce levels of stress, anxiety and depression, he said. “Others have suggested an energy conservation hypothesis, essentially saying that when you burn more calories through exercise, your body more efficiently uses the sleep period to recover. Others have suggested that exercise can modestly reduce body weight, which in turn helps people to sleep better.”

Another theory suggests that exercise helps the body deal better with the cooling down of its temperature during sleep, he said.

So should you avoid exercising before bed, as conventional wisdom suggests? The new research doesn’t look at the timing of exercise, but the study authors do note that most previous studies haven’t shown that late-night exercise disrupts sleep quality.

Study co-author Brad Cardinal, a professor of exercise science at Oregon State, said in a statement that the study is unusual because it directly measured how much exercise people got instead of relying on their memories, which can be faulty.

Mid-Morning Snacks May Thwart Diets

Women who ate between breakfast and lunch lost less, study found.

By Kathleen Doheny
HealthDay Reporter

TUESDAY, Nov. 29 (HealthDay News) — Dieters may want to reconsider that mid-morning snack.

In a 12-month study of 123 overweight or obese women, those who snacked between breakfast and lunch lost less weight than those who skipped a mid-morning nosh.

The finding may not relate to time of day as much as the short interval between breakfast and lunch for these snackers, explained study author Dr. Anne McTiernan, director of the Prevention Center at the Fred Hutchinson Cancer Research Center’s Public Health Sciences Division.

The women may have been eating out of boredom, or for reasons other than hunger, she said. The net result is too many calories in a day.

“Snacking, per se, isn’t bad, it’s more what you eat and when you are snacking,” she said. “If you start snacking in the morning, you might be eating more throughout the day and taking more food in.”

Smart snacking can be part of a sound weight-loss plan, McTiernan noted. The timing of snacks, frequency of eating them and quality of snacks all have to be considered, she added.

The study is published in the December issue of the Journal of the American Dietetic Association. The U.S. National Cancer Institute and U.S. National Institutes of Health funded the research.

McTiernan assigned the women, aged 50 to 75, to either a diet-alone program or a diet plus exercise program. Those in the diet-alone group ate 1,200 to 2,000 calories a day, depending on their starting weight. Those in the diet and exercise group also reduced calories but, in addition, put in 45-minute workouts five times a week.

The participants were given counseling about nutrition but no special instructions about snacking.

The women recorded the time, type and frequency of meals on a normal day. The researchers evaluated calories from fat and fiber, fruit and vegetable intake, and other information.

At the study start, the average body mass index (BMI) was 31.3. (A BMI of 30 is termed obese.) Weight loss in the two groups was similar. Those in the diet-only group lost about 10 percent of their body weight and those in the diet and exercise group lost 11.6 percent after one year.

However, snacking patterns were linked with the amount of weight loss. The mid-morning snackers lost about 7 percent of their total body weight, but those who didn’t snack mid-morning lost 11.5 percent, according to the report.

More women snacked in the afternoon than the morning. Snacks might be appropriate if the interval between meals is long, such as five hours or more, McTiernan said.

Commenting on the study, Connie Diekman, director of university nutrition at Washington University in St. Louis, said that appropriate snacking is key.

“The study shows that appropriate snacking can help with achievement of nutrition goals and aid weight loss,” Diekman said. “While it isn’t conclusive from this study, it appears morning snackers may not lose as much as those who snack later in the day. More studies are needed to assess if this connection is real, is about food choices or if it is just a difference in the individuals,” she added.

“Snacking can help boost nutritional status and often helps manage emotional eating, but the key is choosing the right snack choices,” Diekman explained. “Since this study was done in overweight women it would be helpful to see if similar results occur in normal-weight, postmenopausal women.”

Until more research is in, McTiernan encourages dieters to limit a snack to no more than 200 calories. Healthier snacks include low-fat yogurt, string cheese or a handful of nuts, she suggested. Other good choices are non-starchy vegetables (avoid potatoes and corn), fresh fruits and whole grain crackers.

The study included only women, so the researchers can’t say for sure if it applies to men. “But studies have shown calorie intake is equally important in men and women,” McTiernan noted.

Even Without Weight Loss, Mediterranean Diet Helps Heart: Study

Foods like olive oil and avocados may help body use insulin.

WEDNESDAY, Nov. 16 (HealthDay News) — A new study offers further evidence that a Mediterranean-style diet is good for your heart.

The research found that unsaturated fats from foods such as avocados, olive oil and nuts increase the body’s ability to use insulin. Reduced insulin action can lead to diabetes, which is a risk factor for heart disease.

Researchers examined how three different types of balanced diets consumed by 164 people with mild hypertension but no diabetes affected the body’s ability to maintain healthy insulin levels and regulate blood sugar levels. The three diets were rich in either carbohydrates, protein or unsaturated fats such as those found in olive oil.

The participants ate each of the three diets for six weeks in a row, with two to four weeks off in between each diet. Blood samples were used to monitor insulin and glucose levels.

The diet rich in unsaturated fats improved insulin use significantly more than the high-carbohydrate diet, which featured refined carbohydrates such as pasta and white bread.

This beneficial effect of the unsaturated fat diet occurred even though the participants did not lose weight.

“A lot of studies have looked at how the body becomes better at using insulin when you lose weight,” Dr. Meghana Gadgil, a postdoctoral fellow in the division of general internal medicine at the Johns Hopkins University School of Medicine, said in a Hopkins news release. “We kept the weight stable so we could isolate the effects of the macronutrients. What we found is that you can begin to see a beneficial impact on heart health even before weight loss.”

The researchers said their findings show that dietary changes can improve heart health in those at risk for cardiovascular disease, even if they don’t lose weight.

“The introduction of the right kind of fat into a healthy diet is another tool to reduce the risk of future heart disease,” Gadgil said.

The study was to be presented Wednesday during the American Heart Association’s annual meeting in Orlando, Fla. Because this study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.
