Cardio exercise is such a strange thing. In theory, it should work so perfectly good for all men and ladies, but as anyone who has tried it knows, the practicality of it just doesn't sum up.
At the end of the day, some men and women do cardio 6 hours, 9 hours, or more per week, and still have belly  fat to burn. On the other hand, it works just fine for others.
English scientists wanted to get more insight into this dilemma, and studied 35 fat men and women, who weren't previously exercising.
(Reference: International Journal of Obesity 32: 177-184, 2008).
Subjects worked out 5 times per week for 12 weeks. That's a lot of training, but it helped the subjects lose an average of 8.2 pounds, which is great - I was positively surprised by the results.
So cardio exercise will work for some folks, however, in my experience, it works best in young boys, who need the help the least!
Back to the study, the variance in fat loss between individuals was huge. Check this out...
The best individual lost a staggering 32.3 pounds in 12 weeks, while the worst subject actually GAINED 3.74 pounds.
The researchers think they know where things went sour. Theyclassified the subjects into 2 groups, called the "Compensators"and the "Non-compensators".
The Compensators were hungrier, and as a result ingested an extra 268 calories per day, all but wiping out their cardio efforts.
Therefore, the Compensators lost the least amount of weight, and researchers believe that was due to the huge "compensatory" increase in appetite experienced by this group.
Does your appetite increase when you do slow cardio? If it does, studies show it will ruin your cardio efforts.
So if your cardio program is not working for you, check your appetite and calorie intake to see if you are "compensating" for your efforts. If you are, you might be better off using a program of high-intensity resistance and interval training (i.e. Turbulence Training) for your weight loss efforts.
As Australian Professor Steve Boucher has demonstrated in his research, interval training increases hormones called catecholamines. And increased catecholamines can reduce appetite, among other fat-burning benefits.
In the real world, few people lose 33 pounds after 12 weeks of cardio. hell, few  people even achieve an average weight loss of 8 pounds with aerobic training.
So again, check your appetite, and consider giving high-intensity workouts a go for your next workout program.
Beat the curse of cardio with high-intensity Turbulence Training.
