Cut just 100 calories a day.
That's all you need to ditch to beat belly bulge, says Mehmet Oz, MD, author of YOU on a Diet: The Owner's Manual for Waist Management. Dropping this amount from your daily intake -- we're talking one cookie, a soda, or a glass of wine -- will help you lose about 12 pounds a year. And it's a cinch to stick to a plan that requires no actual dieting or deprivation.
Build muscle mass.
During a cardio workout, your body zaps hundreds of calories, but your metabolism slows down almost instantly when you stop. After strength training, on the other hand, you burn fat for hours. "Regular weight lifting can boost your metabolic rate by about 15 percent," says Tim Davis, director of personal training at Peak Performance, a gym in New York City. He recommends three 45- to 50-minute sessions a week.
Run from fat.
One of the most effective ways to reduce flab around your middle is to jog it off. "Hit the road for 30 to 60 minutes two to four times a week," Davis suggests. Steady running not your thing? "Interval training -- constantly switching up the pace of your workout -- will also help you lose weight, because it blasts more calories," Davis says. "Do two minutes of sprinting followed by a 60-second walk, then repeat for a half hour."
Eat good-for-you foods.
Your body is smart -- it knows when it's not getting any nutrients. So if you munch on processed foods like chips and doughnuts, you'll still be hungry, Dr. Oz says. The fix: Chow down regularly on fruits, vegetables, fish, low-fat dairy, and whole grains, says Keri Gans, RD, a spokesperson for the American Dietetic Association.
Have a high-protein breakfast.
Skip the sugary cereals. They're too easily digested, which means they speed through your system. "An egg-white omelet is a good choice," says Louis Aronne, MD, a clinical professor of medicine at Weill Cornell Medical College and director of the weight-control program at New York-Presbyterian Hospital in New York City. If you're eating on the go, try unsweetened Greek yogurt with fruit and a dollop of honey or a piece of string cheese with whole-grain bread.
Don't skip meals.
That will only set you up to overeat. "Nosh on small portions every three to four hours to keep your metabolism running, so your body won't panic, go into starvation mode, and stop burning calories -- which is what happens when you haven't eaten in a while," Gans says.
Head off a freak-out.
Stress causes the body to start stockpiling fat in the gut. "Your system thinks a crisis is coming," Dr. Oz explains. "It deposits fat cells into the belly because it's the most convenient storage space." Chill out with yoga, meditation, or massage. If you're a stress eater, keep healthy snacks such as almonds on hand to prevent junk-food binges.
Get your shut-eye.
"Lack of sleep increases the likelihood you'll gain weight," Dr. Aronne says. "When you're tired, the hormones that stimulate appetite increase, while the hormones that help you feel full plummet." Aim for seven to eight hours a night.
Move more all the time.
Computers, TVs, video games, and cars keep us glued to our seats. The result: We're less physical than ever before. To trim your tummy, "do whatever you can to keep moving," says Olson. "Even 10 minutes can help." Studies show that you can burn up to 350 calories a day (the equivalent of your lunch!) by walking around when you're on the phone, tapping your toes when you're surfing the Web, doing squats when you're brushing your teeth. Before you know it, you'll be saying bye-bye, belly fat!

Eat, Exercise, Relax, and Sleep Your Way to Better Sex
Better sex doesn't just involve technique. Keeping a fit mind and body can increase your enjoyment of bedroom antics.
By Dulce Zamora
Thought about leading a healthier lifestyle but haven't gotten around to doing it? Here's a possible incentive: Experts say people who are mentally and physically fit are more likely to have good sex lives. "If you feel good about yourself, you are in a better position to feel good about relationships, including your sex life," says Karen Zager, PhD, a psychologist in private practice in New York City.
"When one is not feeling well, and is exhausted, it can certainly have a negative impact on the quality of one's sex life," says Saralyn Mark, MD, a senior medical adviser at the Office on Women's Health.
This may all seem intuitive, yet many people find the road to a fitter mind and body to be bumpy, especially if it involves losing weight, starting an exercise program, reducing stress, or getting enough sleep.
One big reward, though, is to look and feel better -- arguably a plus for good romantic and sensual activities.
Eat Right
While there is no proven connection between a balanced diet and bedroom performance, a poor diet can cause health problems that can possibly interfere with sex.
Studies show animals that get too few calories tend to have weakened immune systems, says John Allred, PhD, professor emeritus of nutrition at Ohio State University. He says illness can be a big hurdle for pleasurable intercourse.
"If you have heart disease, then you might be taking medication that would inhibit sexual activity, or you might be afraid to have a heart attack," says Allred. "If you have the flu, a high fever, or just don't feel good ... any of these things would be a turn-off."
Mark Kantor, PhD, associate professor of nutrition and food science at the University of Maryland, agrees, saying, "You will feel sexy if you look and feel good."
A way to do that is to eat an overall balanced diet and to exercise each day. The two go hand-in-hand, says Kantor, as demonstrated by today's obesity problem, in which people eat too much food and aren't active enough.
Move That Body
Being physically active can be a natural Viagra boost, according to the American Council on Exercise (ACE), which recommends 20 to 30 minutes of moderate exertion a day.
"Men and women who exercise regularly are going to have increased levels of desire," says Cedric Bryant, PhD, ACE's chief exercise physiologist. "They're going to have enhanced confidence, enhanced ability to achieve orgasm, and greater sexual satisfaction."
If that isn't motivation enough to work out, consider this: Researchers have found that there is a correlation between waist size and a man's odds of having erectile dysfunction (ED). The larger the man's waist size, the greater his chance of having ED (because of a higher risk of underlying cardiovascular disease).
Need more positive reinforcement? Studies show that regular, moderate exercise can have a positive benefit on major sexual problems, such as ED in men and low libido in both men and women.
It only makes sense, say experts, since ED is often caused by poor blood flow to the penis, and exercise can improve the body's ability to pump and circulate blood throughout the body.
The same can be true for the ladies. In one University of Texas at Austin study, physically active women who watched an X-rated film had a 169% greater blood flow to the vagina compared with when they were inactive.
And there's more good news. Mark says exercise can promote the body's release of hormones important for sexual arousal, increase aerobic capacity and muscle strength, and boost self-body image -- all definite benefits for between-the-sheets play.
Sweet Dreams
For many of us, a good roll in the sack requires energy and the right mood -- elements that can be compromised when we are sleepy or tired.
While there is no direct relationship between slumber and better sex, a National Sleep Foundation (NSF) poll, conducted in 2002, shows people's moods can be affected by the amount of shut-eye they get.
People who sleep less than six hours are more likely to report they are tired, stressed, sad, and angry than those who sleep more than eight hours. On the other hand, those with few sleep problems tend to report they are "full of energy," "relaxed," and "happy."
In his practice, Russell Rosenberg, PhD, director of the Northside Hospital Sleep Medicine Institute in Atlanta, says chronic sleep-loss patients report not only being too physically tired for sex, but also having decreased libido.
Unfortunately, lower sex drive, tiredness, and grouchiness are the least of worries with sleep deprivation. Research shows people who don't catch enough winks tend to:
• Get into more accidents. Inadequate sleep affects perception and motor skills.
• Find it harder to lose weight. Not enough shut-eye can affect the body's ability to metabolize carbohydrates.
• Have an increased chance of a hormonal or metabolic disorder, which can indirectly put you at risk for medical problems such as type II diabetes and heart disease.
All of these consequences could undoubtedly put a damper on a person's sex life.
Rosenberg recommends trying to increase your total sleep time, even if it's just adding a half-hour or more per week. "Try it, and see how it affects your sex life," he says.
Relax
The brain may be the most important sex organ of all. It is perhaps in the mind where beliefs take hold and flourish about the effects of certain foods on sexual prowess, even as scientists deny any direct connection between diet and erotic fitness.
It is in the mind that people feel self-confident when they like the effects of exercise on their bodies. It is also where they feel happy and energized once they've gotten enough sleep.
Yet the inner workings of the brain can also keep a person from focusing on the delights of bedroom actions.
"In order to have a really healthy and pleasurable sex life, you have to be able to dismiss work; you have to be able to unwind and experience pleasure," says Zager. She says this means being able to temporarily forget about what your boss said, what was in the memo, what bills need to be paid, and what the children need.
Sex requires relaxation and time, adds Zager, noting that some couples may be too stressed and busy to enjoy or even have intercourse. She suggests setting priorities.
"Just how important is sex to you and your partner?" asks Zager. If it is vital to your relationship, she advises finding a way to work it into your schedule and working on making yourself less stressed or tired.
Some recommendations include eliminating some activities from your busy life, delegating jobs to someone else (by giving it to a partner, or hiring someone to do it), and doing an across-the-board cut in time spent on each activity.
To unwind, Zager suggests taking 5 to 30 minutes either to walk, meditate, take a hot bath, do yoga, or sit by yourself. This time can help charge personal batteries and can help make transitions between your work, family, and sex life.
To Your Bedroom Health
Living healthy may, indeed, have its benefits. If you eat a balanced diet, exercise regularly, sleep enough, and take time to relax, there's a good chance your life between the sheets will improve.
Of course, there is no guarantee. But, as Zager says, it all forms a really good foundation.
"If you've got a good foundation of stress management, and setting your priorities, and taking good care of yourself, then on top of that, you can build relationships with other people and an enjoyable sex life," she says.
Before you jump on that Stairmaster or start pounding the pavement, make sure you have a cardio exercise plan that will give you the most bang for your muscle burn.

Whether it's pounding the pavement, logging miles on the bike, or climbing those stairs that seem to go nowhere, it's all about cardio exercise. But other than a sweaty t-shirt, what do you have to show for your workout? A slimmer stomach? Killer quads? Are you exercising for the right amount of time to reap the full health benefits of cardiovascular fitness, or often enough?
Exercise experts, including fitness maven Denise Austin, answer cardio questions for WebMD, so you can make the most of your muscle burn.
Cardio Exercise: The Heart of the Matter
"Cardiovascular exercise is any type of exercise that increases the work of the heart and lungs," says Tommy Boone, PhD, a founding member of the American Society of Exercise Physiologists. "Walking, jogging, and running are common forms of cardiovascular, or aerobic, exercise."
From running and walking, to swimming, elliptical cross-training, biking, Stairmaster, and rowing -- to name a few -- the physical benefits of cardio exercise abound, explains says Len Kravitz, PhD, senior exercise physiologist for IDEA Health and Fitness Association. They include:
Reduced risk of heart disease:
- Improved blood cholesterol and triglyceride levels
- Improved heart function
- Reduced risk of osteoporosis
- Improved muscle mass
"The American College of Sports Medicine and the CDC recommend, for health, that adults should accumulate 30 minutes of moderate-intensity physical activity on most days of the week," says Kravitz, who is also a coordinator of exercise science at the University of New Mexico. "And to improve cardiovascular endurance, they recommend 20 to 60 minutes on three to five days per week."
Now that you know the benefits of cardio exercise, where should your heart-pumping fitness plan begin?
Getting Into the Zone
To help you make the most of your cardio exercise workout -- help your heart, increase muscle, and lose fat -- Denise Austin, fitness expert, author of seven books, including Shrink Your Female Fat Zones, and star of 50 fitness videos, gives WebMD some tips.
"To reap all the benefits of a cardio workout, you should sustain your workout for 20 minutes or more -- I do 30 minutes myself -- on a schedule of about three to four times per week," says Austin.
Not only that, but you need to get in the zone, which calculates into burning calories and fat.
"The best way to find out if you are burning fat is to take your pulse halfway into your cardio workout for six seconds, then add a zero to that number," Austin tells WebMD.
This number is your heart rate per minute.
Next, calculate your zone.
"Take the number 220, then minus your age, then calculate 70% of that number for your target beats per minute," says Austin, and that's your zone. "If your heart rate halfway through your workout is over that 70% mark take it down a level, and if under, pick up the pace."
Not a math wiz? There are easier ways to figure it out.
"Another great way to find out your zone is to get a pulse monitor, which takes the math out of it," says Austin. "Or very simply, take the talk test: while you are doing aerobics, talk a sentence. If you are too winded to finish the sentence, you are overdoing it, or if it's too easy to say, kick it up a notch!"
Getting Cut With Cardio
If you're looking for ripped abs and toned arms, interval training will help get you there -- especially if you throw in some weights.
"I love interval training because it consistently jump-starts your metabolism," says Austin. "Let's say you are walking -- you could power-walk really fast for three minutes to get the burst of calorie burn, and then walk calmly and slowly for one minute, which offers recovery. By switching back and forth, you push the muscle and let it relax over and over and this gives you maximum results." You can do interval training on any type of cardio exercise machine -- alternating a high intensity with a more moderate level.
Austin suggests doing weights during your recovery time, such as bicep curls or tricep toners, to reap the benefits of both cardio exercise and weight training, and along with interval training, add dedicated weight sessions to your regimen to burn fat and sculpt muscle at the same time.
"Do cardio four days a week for 30 minutes, and add a weight-training workout at least two times a week at 20-minute sessions," says Austin. "Cardio will burn the fat, and it's the weight training that gives you the toned sculpted look that will have you bikini ready."
Cardio's Best Fat Burner
So you want the bottom line: Which cardio exercise will fat-bust the best?
"Running is the best option for calorie burning, in my opinion," says Niki Kimbrough, personal fitness expert with Bally Total Fitness. "Whether it's outside or on a treadmill, it's the best exercise because you're burning calories and you're strengthening your legs and heart -- it'll get you nice and lean."
Beginners should start with 20 minutes, explains Kimbrough, and work their way up.
"It takes about 20 minutes for your body to get going, and then your body starts to kick it to another level," says Kimbrough. "Ideally, you want to run for about 30 or 45 minutes."
For those with bad knees, Kimbrough recommends the elliptical machine as a good second choice.
In case running isn't your game, Kravitz takes another track.
"I really feel the most important message is to chose a cardio modality or modalities that you like," says Kravitz. "Because in the final outcome, if a person enjoys a mode of exercise, that is what all research shows they will choose."
Splitting It Up
While it may not be the fastest way to a body built for the beach, splitting up your cardio exercise still has its benefits.
"In order to achieve the best results, and also in order to maintain a healthy heart, it is best to not split up your cardio workouts," says Austin. "You need the consistency of 20 minutes or more of an elevated pulse to ensure great results. However, something is better than nothing. If all the time you have is 10 minutes or even five minutes, it is better than sitting still; you will still be garnished benefits and lose weight."
Kick Up Your Cardio
Let's be honest -- cardio exercise can get boring after awhile. How can you jazz it up and make it interesting again? The experts recommend never letting it get stale in the first place.
"I believe you should do different types of cardio exercises during the course of a week, if possible," says Austin. "The thing to remember is that too much repetition will fatiguemuscles and you will plateau, which will slow your results down. By adding variety to your workouts you give muscle groups a chance to recover on their days off and you can maintain a steady progress."
Kravitz agrees with adding options to cardio exercise.
"Vary the mode, vary the place you train, vary the workout, vary the time of day, vary the intensity of the workout, vary the duration -- vary, vary, vary," says Kravitz. "That is what I have found to work the best for exercise compliance."
Before starting a new exercise program, it is important to have a discussion with your doctor about types and levels of activity. Your doctor can advise on any limitations or restrictions you may have.
