Not a pretty picture is it?

BAD NEWS

Abdominal Visceral Fat (aka Belly Fat) has been strongly linked to:

  • Depression
  • Heart Disease
  • Cancer
  • Systemic Inflammation
  • Diabetes
  • Metabolic Syndrome
  • Death

In a nutshell, a big gut is not a good thing.

GOOD NEWS

High Intensity (HIIT and/or HIRT) Training burns off belly fat faster than any other form of exercise.

The Magic of HIIT

The Science

Study # 1

In 2008, researchers took 27 middle-aged obese women with metabolic syndrome and subjected them to one of three exercise programs.

  • Group 1 was the no-exercise control group
  • Group 2 was the low intensity (aerobic) exercise group -
  • Group 3 was the high intensity (HIIT) exercise group

Groups 2 & 3 performed 5 workouts per week @ 400 calories per workout.

After 16 weeks, the HIIT group had significantly reduced total abdominal fat, abdominal subcutaneous fat and most importantly abdominal visceral fat.

Sadly, Groups 1 & 2 saw no significant changes in fat loss.

Study # 2

In study #2, researchers took 45 normal women (mean BMI 23.2plusminus2.0 kg m-2 and age of 20.2plusminus2.0 years) and subjected them to a 15 week HIIT exercise program.

As in the first study, the women were divided into 3 groups.

  • Group 1 was the no-exercise control group
  • Group 2 was the low intensity (aerobic) exercise group -
  • Group 3 was the high intensity (HIIT) exercise group

After 15 weeks, both exercise groups demonstrated a significant improvement in cardiovascular fitness.

However, only the HIIT group had a significant reduction in:

  • total body mass (TBM),
  • fat mass (FM),
  • trunk fat
  • and fasting plasma insulin levels.

.

Conclusion

 

High Intensity training (HIIT or HIRT) is more effective than cardio training for burning off belly fat.

In study 1, did group 3 really performed HIIT 5 times a week? In the real world, you likely can't perform it more than 3 times a week at maximum intensity because you would be too tired and slow down. Even if you can, you may overtrain.
For low intensity cardio, what was the heart rate, and did they exercise until they can carry on breathless continuously?
I've read articles stating that cardio (75% HR) was more effective than resistance training or both combined. Resistance training had no reduction
It would be interesting to know if HIIT or cardio has a bigger preferential target for visceral fat. Incorporating HIIT certainly is better for overall reduction of body fat than steady state cardio.

Gotta love HIIT. First time I lose weight was by doing kung-fu 3 times a week - those were certainly HIIT classes. Great workouts. Most competitive martial arts provide a good workout (non-competitive guys often take it a bit too easy ....)

regarding the picture with the swimmer.. are you trying to say it's the same guy in the left, the one with 100 bags of chips around his waist?:)) come one... HIIT might work, but that's unvelievable

Nope - 2 different guys
One of them is an Olympic weightlifter...can you guess which one?

Hi Doug: Really like your succinct presentation of the study results and love that you are getting the word out. Will you be doing a post that focuses on the second "I" in HIIT as you do not mention the Interval factor much. Keep spreading the message and not the middles! Ahh haa

that picture is fake, right? no one can believe that it's the same guy, before and after, not even me, although i've seen some pretty good results with some guys, even akebono:P

Totally fake - 2 different guys

How many times have you heard it mentioned that sugar causes cancer, that cancer patients should avoid sugar, or that sugar is the favorite food of cancer cells? The truth is, this goes beyond mere hearsay or traditional knowledge; there is actually a large volume of scientific evidence available which shows the link between sugar and increased cancer risk.
A study team at Duke University School of Medicine has suggested a possible reason why cancer cells like sugar so much.
Basically, according to the researchers, in healthy cells, certain growth factors regulate their metabolism and cell survival. When these growth factors are removed, there is loss of glucose uptake and metabolism, and the cells die.
However, they found that cancer cells are able to maintain glucose metabolism by using a protein called "Akt", which promotes glucose metabolism. This prevents cell death, even when the growth factors are not available.
Refined sugar is devoid of important nutrients, causes obesity, causes cavities, and also increases cancer risk. If you or a loved one are battling cancer, or are serious about avoiding the disease, you may want to take note of your intake of this common yet dangerous substance.

Amen brother. That's all I have to say about that.
