If you like to jog, then don’t read this. If you are doing it because you want to lose weight and get healthy, please continue.
Jogging is running at a gentle pace.The definition of jogging as compared with running is not standard. One definition describes jogging as running slower than 6 miles per hour (10 km/h).Jogging is also distinguished from running by having a wider lateral spacing of foot strikes, creating side-to-side movement that likely adds stability at slower speeds or when coordination is lacking.
Here are three facts to consider before reading from my opinion:
1.International Journal of Obesity: Williams, P. Wood. The Effects of Changing Exercise Levels on Weight and Age-Related Weight Gain. International Journal of Obesity. 2006. 30)3), 543-551
WHAT THIS SAYS: In this study 12,568 runners were tracked for 9 years. The majority of the runners gained body fat and increase waist circumference during that time period, even if they never quit running. The only one’s who didn’t get fatter were the one’s who increased their running significantly during this period, some by as much as 3 times the amount they started with.
WHAT IT MEANS: Of course this is one study but it does display some important evidence that “jogging” isn’t the answer to fat loss. Losing fat is ultimately about spending more calories than you take in. So with this study the emphasis is on moving more and not necessarily on what you put in your mouth. A point that needs to made is about homeostasis. Your body will do everything it can to stay the same and will not change unless you force to adapt to a new stimulus. Meaning your body will eventually adjust to what you are doing and become more efficient. As with all exercise, this boils down to a change in intensity or volume. We already have defined jogging as running at a “leisurely,” pace, which means our only option is to bump up the volume to increase the number of calories a person is spending. The data clearly displayed that the only successful runners’ in regards to weight loss were the one’s who ran more. Obviously, more time dedicated to exercise isn’t very practical for most.
2. Jim Fixx, The Complete Book of Running
WHAT THIS SAYS: Jim Fixx was said to start the “jogging,” craze in America when he published his bible on running. In a sad twist of irony, Fixx died at 52 from cardiac arrest following his daily run. Doctors later determined that his death was largely due to many lifestyle factors.
WHAT IT MEANS: This should be a pretty foregone conclusion that “jogging,” alone can’t solve all our health related problems or even come close to preventing them. In my experience with clients is that there exist’s a tendency to rationalize unhealthy behavior’s because we put effort into something that is “healthy.”

WHAT THIS SAYS: These studies conclude that injuries to the knee, hip, ankle, and shoulder do occur in a large number of “runners.” Studies estimate that between 19.4% and 79.3% of runners sustain an overuse injury in a 1 year period. The evidence in from the studies determine’s we can expect 4 injuries per 1,000 hours of running.This amounts to 2 injuries per year for each runner running 5 to 10 hours a week. Even after recovery 20 – 70% of runners will have a recurrence injury.
WHAT IT MEANS: Injury from “jogging,” is almost unavoidable. Consider that each time our foot hits the ground while jogging, our foot and ankle must absorb an impact of up to 8-times the amount of our body-weight. The Centers for Disease Control has determined the average weight for a person in North America is 195 pounds. That means the average person would would be taking about 1,600 pounds every step while jogging! That’s a whole lot of stress for a perfectly designed skeletal system. The problem is that most people who decide to “get up and get fit,” don’t have perfectly aligned skeleton’s.
My business (www.romfit.com) is teaching people exercise’s to avoid chronic pain due to largely from bones being out of alignment. The most common postural deviation I see is overpronation (flat-feet; loss of arch). I would guess 75% of my client suffers from this. For folks that overpronate, their foot rolls in too much after their heel hits the ground while running. This is a problem because their knee get’s tugged along with it , which creates a whole lot of stress which could ultimately be felt up through the shoulder. My point is that not many in this country are aligned perfectly, and for those that aren’t it is very easy to see the risks for injury involved in running.
My completely honest opinion is that “jogging,” can have as much of negative influence on our rates of obesity as many other lifestyle factor’s. If the chances of getting injured and re-injured are as high as reported this means there are two very important question’s to consider.
1. If people aren’t moving as much because they are on the mend, then what are they doing? NOT MOVING. If the generally excepted equation for fat loss is move more and eat less, then we have an obvious problem. The prevalence of fat accumulation and an increase in waist circumference measurements will continue to rise.
2. If avoiding things we like to do because we can’t move, what are the chances of depression setting in? JUST A GUESS, BUT HIGH. If you can’t move well then obviously there will be certain things that you won’t participate that would normally. The typical way that folks will feel this void is with high-fat and high-sugary foods. Obviously, this is a problem.
I really don’t think our body was designed to run for great distances at a time. I think we have an amazing capacity to continually adapt to allow us to, but if look at evolutionary trends to compare us back to our ancestral route it doesn’t appear as if we ever needed to. Consider the fact that early humans would feed from animals they would catch. We don’t need scientific data to hypothesize of the likelihood of anyone ever chasing down an animal for multiple miles at a time.
