Possible Upcoming Article Subject
I haven't blogged much lately, but I wanted to drop a quick note and let you guys know about an interesting study we're exploring here on MyFitTribe.
The subject is one we found very, very interesting. Our team was performing a lot of research lately going through studies and examining how fat is linked to various diseases such as cancer and diabetes and we came across a study that compared the visceral fat percentages of different groups of exercisers (visceral fat is the fat around your organs). It claimed that; of all the participants who exercised, only the people who jogged at least 32kilometers a week lost any visceral fat (the really bad kind). All other groups (even those who ran 19Kms a week, and those who walked 19kms a week) actually went up a bit or didn't change at all. The sedentary group went up 9% (not surprising). This was a very interesting study result, since 32km per week of running is actually relatively high for a lot of strength trainers. And a lot of time you hear people complaining about how they "just can't lose fat" even though they seem to exercise a lot.
Anyhow, we're going to try to dig up more information on these studies to see why this happens, and perhaps locate more studies that correlate those findings.

Very interesting stuff Dan.
Very interesting stuff Dan.
I believe
that's because of when and how your body chooses to use which energy sources.
As we all know, carbs are the most prevalent source for energy.
We'll have to look at those people in the study and see if they changed up their diets at all???
B/c if you lower your carbs, and increase your fats, and maintain a higher protein amount... then slowly lower carbs while increasing fat and protein to account for the decease in overall calories, your body starts to adjust...
it's also very tricky to get your body to tap into certain adipose tissue cell types...
some require exact diet % of macronutrients, and certain intensities of exercise (cardiovascualr) and not just types, but times...
i've seen before that it takes about 15-20 minutes before you start to tap into energy stores like fat... then on the other hand i read a really well credited article focusing on the fact that it only takes a few minutes, say 5?? or somethign like that... but im sure those were intense 5 minutes, with a higher heart rate and MAX V02 rate..
intensities also vary b/c the more intense, the faster your body as to get that energy, which explains why higher intensities require lots of carbs, and lower intensites can utilize fat storage after X amount of time.. which is why they say exercise at 70% MHR or around there to utilize the most fat..
and ALSO why exercising your CARDIO on an EMPTY stomach works well, as long as you make sure you dont use ur own muscle tissue as fuel... so maybe drink a small protein shake... b/c ur not going to use protein as energy , that's not how our bodies are made.. we dont look for protein for energy, our first sources are carbs,,... then once sources are exhausted, our bodies look elsewhere... which is why its so hard to pinpoint WHEN and HOW our bodies use fat for energy...
Good Points
But what I found most interesting about the study was not the OVERALL fat loss of the groups, but rather the specificity of the visceral fat loss. Because they alluded to the fact that some people in the shorter walk/run group could have lost subcutaneous and retro fat, but not visceral fat! And of course, the ultimate goal for any "apple" shaped people is to lose fat from their waist area, since (from what I understand) it is the visceral fat that is "active" and contributes to "bad" (IGF, leptin, etc) hormone secretion.
Dan,
this is very intersting. I cant wait to learn more. Im going to have a look through my journals to see if i can pick up on any info in regards to this subject.
peace!
