Running is one of the best forms of aerobic conditioning for your heart and lungs. It can significantly increase your metabolic rate and the amount of calories you burn, leading to loss of excess body fat. Running is also beneficial for slowing down the aging process. Those who run regularly are less likely to experience bone and muscle loss due to the body’s positive response to additional physical demands.

Running can also have many psychological benefits. Most runners typically report being happier and feeling less stressed from the grind of daily life. Why? Because regular exercise has the ability to alter mood, attributable to a surge in hormones called endorphins. These hormones create a sense of euphoria often referred to as a “runner’s high” and can result in an improvement in mood.

Here are some great tips, courtesy of running coach Chipper Robinson from Running on the Edge in Ramsey, N.J., on how to maximize your running experience:

* Incorporate cross training into your running routines. Add weight-lifting, bicycling, yoga, elliptical training, or swimming. Why? They make you fitter and less prone to injury.

*Exercise your abdominal muscles almost every day. A strong midsection (core) is a key component to running. In fact, it can often be the single most important factor for success in long-distance running.

* Change your intensity levels by running faster or farther. Alternate which one you choose to implement in various workouts. It prevents your body from adapting to routines.

*Pay attention to your shoes. Most shoes wear out after 300 to 500 miles. You often can’t see the wear, but, your knees, hips, and back will feel it. Visit a running specialty store for quality shoes and talk to your doctor for suggestions on the best shoes to get. Not just any shoe will do.

* Run on different surfaces. See how many different surfaces you can run on in a month: asphalt, gravel, trail, grass, track, treadmill, and beach. Each stresses your leg muscles in a slightly different way, helping to prevent overuse injuries. (If possible, avoid concrete, the hardest and most harmful surface for runners.)

* Keep a training journal. A journal can be a great way to maintain motivation and consistency. Keep it filled with running times, routines, motivational quotes, and how your body reacts to various routines. You should have a documented road map for reaching your running goals.

* Take some time off. You don’t have to run every day, every week, or even every month (as long as you’re performing other cardiovascular activities). For healthy, consistent training, your body needs regular recovery periods. Performance suffers with too much exercise. Start slow and work your way toward higher mileages and/or more frequency.

* Introduce high-intensity interval training into your running routine. Alternate, pace, speed, tempo and rest periods during a single running session. For example, keep a steady pace for a mile and then sprint run for 30 seconds. Do this for several cycles and notice how your heart rate and muscle fatigue threshold increase.

Every great journey starts with a single step; now just put one foot in front of the other to see how far this new journey takes you. Welcome to the wonderful world of running. Talk to your doctor to learn more about the benefits of running.

Does More Frequent Meals Really Rev Up Your Metabolism?

You’ve probably heard that eating smaller meals, several times a day will stimulate your metabolism, and keep it revved to burn more calories throughout your day.
…………….CLICK & SEE
The New York Times points out that although some studies have found modest health benefits to eating smaller meals, the research usually involved extremes.

Many weight-loss books and fad diets claim six meals a day is a more realistic approach.

But will it really make a difference?

The New York Times states:

“As long as total caloric and nutrient intake stays the same, then metabolism, at the end of the day, should stay the same as well. One study that carefully demonstrated this, published in 2009 in The British Journal of Nutrition, involved groups of overweight men and women who were randomly assigned to very strict low-calorie diets and followed for eight weeks. Each subject consumed the same number of calories per day, but one group took in three meals a day and the other six.

Both groups lost significant and equivalent amounts of weight. There was no difference between them in fat loss, appetite control or measurements of hormones that signal hunger and satiety. Other studies have had similar results.”

Exercise, on the other hand, seems to effectively increase metabolism according to studies.

Sleep Habits Linked to Fat Gain in Younger Adults

Researchers found that among adults younger than 40, those who typically slept for five hours or less each night had a greater accumulation of belly fat over the next five years.
……..CLICK & SEE
But those who logged eight hours or more in bed each night also showed a bigger fat gain, although it was less substantial than that seen in “short sleepers.”

On average, short sleepers showed a 32 percent gain in visceral fat, versus a 13 percent gain among those who slept six or seven hours per night, and a 22 percent increase among men and women who got at least eight hours of sleep each night.

A similar pattern was seen with superficial abdominal fat. Even when the researchers considered factors like calorie intake, exercise habits, education and smoking, sleep duration itself remained linked to abdominal-fat gain.

The study does not prove that too little or too much sleep directly leads to excess fat gain. But the findings support and extend those of other studies linking sleep duration — particularly a lack of sleep — to weight gain and even to higher risks of diabetes and heart disease.

Many Ignorant of Waist Fat Risk

[amazon_link asins=’B00VSSJYEG,B01HO5ZBNY,B01DQS5XPE,B06Y2JVG8B’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’7bdb8495-4998-11e7-a8e4-8f700ceff42f’]

Almost nine in 10 people are not aware of the risks of carrying extra fat around their waistline.

A survey of 12,000 Europeans found most had no idea that a thick waist was a sign of a build-up of a dangerous type of fat around the internal organs. This “visceral fat” is strongly linked with type 2 diabetes and heart disease.

It is thought that the danger of visceral fat is related to the release of proteins and hormones that can cause inflammation, which in turn can damage arteries and enter your liver, and affect how your body breaks down sugars and fats.

Sugar May Be Bad, But This Sweetener is Far More Deadly

Scientists have proved for the first time that fructose, a cheap form of sugar used in thousands of food products and soft drinks, can damage human metabolism and is fueling the obesity crisis.
……….…..click & see
Fructose, a sweetener usually derived from corn, can cause dangerous growths of fat cells around vital organs and is able to trigger the early stages of diabetes and heart disease.

Over 10 weeks, 16 volunteers on a controlled diet including high levels of fructose produced new fat cells around their heart, liver and other digestive organs. They also showed signs of food-processing abnormalities linked to diabetes and heart disease. Another group of volunteers on the same diet, but with glucose sugar replacing fructose, did not have these problems.
