What Everybody Ought To Know About Exercise

I have been exercising daily for the past nine days, doing the Slim in 6 'Ramp it Up' workout.

I had forgotten how good exercise makes me feel - physically, emotionally, and mentally. I feel like a new person. I feel healthy and clean on the inside.

In addition to my appetite decreasing, my cravings for unhealthy foods has decreased as well. Instead, I've been wanting to drink more water.

The only explanation for how I feel now is the fact that I've been exercising.

Here's a quote from the article below:

"Volkow knows - from her own 6-mile daily runs and from her scientific experiments - that the brain literally likes physical activity. Exercise seems to invigorate neurochemicals that sense and reinforce pleasure."

The article below is about the benefits of exercise as it relates to the prevention of drug or alcohol addiction. I believe that exercise can prevent food addiction as well.

Can Exercise Help Prevent Addiction To Drugs Or Alcohol?
by Lauran Neergaard, AP Medical Writer

Sure, exercise is good for your waistline, your heart, your bones - but might it also help prevent addiction to drugs or alcohol?

There are some tantalizing clues that physical activity might spur changes in the brain to do just that. Now the government is beginning a push for hard research to prove it.

This is not about getting average people to achieve the so-called runner's high, a feat of pretty intense athletics.

Instead, the question is just how regular physical activity of varying intensity - dancing, bicycling, swimming, tae kwan do - might affect mood, academic performance, even the very reward systems in the brain that can get hijacked by substance abuse.

What first caught the attention of National Institute on Drug Abuse chief Dr. Nora Volkow: A study found tweens and teens who reported exercising daily were half as likely to smoke as their sedentary counterparts, and 40 percent less likely to experiment with marijuana.

Volkow knows - from her own 6-mile daily runs and from her scientific experiments - that the brain literally likes physical activity. Exercise seems to invigorate neurochemicals that sense and reinforce pleasure.

"In children, it's innate," she notes. "Children want to move."

But the nation's children are becoming more sedentary, as illustrated by the obesity epidemic, "screen time" replacing outdoor play and a drop in school P.E. And as youngsters approach adolescence, the run around the yard that used to be fun too often becomes a chore _ the dreaded jog around the school track or the nagging to get off the couch. The sedentary teen turns into the sedentary adult.

"Why do we lose the ability to experience pleasure from physical activity?" asks Volkow.

Last week she brought more than 100 specialists in exercise and neurobiology to a two-day conference to explore physical activity's potential in fighting substance abuse, and announced $4 million in new research grants to help.

Drug treatment programs often include exercise, partly to keep people distracted from their cravings, but there's been little formal research on the effects.

The best evidence: Brown University took smokers to the gym three times a week and found adding the exercise to a smoking-cessation program doubled women's chances of successfully kicking the habit. The quitters who worked out got an extra benefit: They gained half as much weight as women who managed to quit without exercising, says lead researcher Dr. Bess Marcus.

She now is working with the YMCA on a larger, NIDA-funded study to prove the benefit.

Marcus cautions that people trying to kick an addiction have a powerful incentive to exercise. Could that possibly translate into prevention? Among the clues:

• Rats were less likely to ingest amphetamines if their cages had running wheels, suggesting exercise stimulated a reward pathway in the brain to leave them less vulnerable to the drug's rush.
  
  
• In people, exercise acts as a mild antidepressant and relieves stress. Depression, anxiety and stress increase risk of alcoholism, smoking or drug abuse.
  
  
• Volkow is intrigued that attention deficit disorder and obesity both involve problems with the brain chemical dopamine, one system that drugs hijack to create addiction.
