Nutrition Guidelines and Marketing – Who Can You Trust?

by John Barban

Nutrition guidelines are handed to us by government departments and most of us will blindly assume that the guidelines are both accurate and up to date.

The truth of the matter is that much of the guidelines you see are heavily lobbied for by industry and don’t represent a true unbiased scientific opinion of what is the truth.

Government mandated guidelines and marketing health claims are usually only an interpretation of some of the science available and should never be taken as a fact that can be applied to all people.

When it comes right down to it, your body and your health is your responsibility and requires you to do some digging to find out if the guidelines you’re told and the claims you read are even worth the paper they are written on.

In just about every case the claim or guidelines you’ve read have much more than just your best interest at hand.

Hey guys… don’t forget to leave a comment and let us know what claims, research, or guidelines that you want us to deconstruct for you next week.

My vote is for the interval training study… :)

I can’t get these podcasts to download or play. Any suggestions?

I’m interested in the interval training, particularly an Australian study that I’ve linked to that showed significant results from interval training on stationery bikes.

I’ve also read that a short burst of intervals followed by 5 mins rest causes a release of fatty acids into the bloodstream, then you should perform steady state exercise to burn off these fatty acids

I’m interested in your opinions on these ideas and included links to the studies.

You can’t “right click save as” on the “download” link?

No idea. It’s working for me…

I can’t get them to work either (none of the last 3, including the “Fitness Marketing” one), which is really a bummer.

And when I try to download it, it never starts and stays at 0.

Works for me. Good stuff.

I agree with brad with the hiit and tabatha training studies

I’m still working through some of the archives so if this has already been addressed please ignore…

The ones that seem to most flabbergast me and others I know is “how XYZ fat burner can melt fat like butter on a hot griddle” or some similar nonsensical claim.

Ty

What about any studies on testosterone boosters like Protodioscin? Do they work, how they work etc..

Baking Soda as A supplement. there are not to many articles and stuff on that on the internet that are easy for the adverage joe to understand.

Ok so I have started a weight loss regimen simple by accident after losing a girlfriend and I didn’t eat for a while. I lost 6 pounds in a week..I decided instead of falling on my face I would change my routines to be as healthy as I could. Not only would I recover physically, but mentally as well. I started at 234 in early September and now I am 205 give or take a few pounds for fluctuations..just a bit of back story.

I was recommended to only lose 2 pounds per week or it would be dangerous and I would get stretch marks if I lost more then that..is this true?

Also, I was told by a GNC employee to take “BetaStax” to improve my overall weight loss. The Bottle reads”Precision Multi-Pathway extreme weight loss Catalyst. powered by(bold&highlighted) University tested bio-active weight loss matrix” whatever all that means “Ultra rapid action cap technology” It is distributed by BioQuest a division of NutraQuest. The blends in the caps are Xanthicore Proprietary Blend & Purewayslim Proprietary Blend. I have lost weight but don’t know if these are actually helping or not. I could not find what university study they pulled information from.

Thanks for any help!

Hey guys-I just read an article about bmr on a fitness website. They talked about fat loss and said the usual stuff but pointed out that a calorie deficit is essential. Ok, so that was good. But then they talked a little about gaining muscle and said “Positive calorie balance is essential to gain lean bodyweight” and “It is a basic law of energy balance that you must be on a positive calorie balance diet to gain muscular bodyweight”. Can you possibly discuss studies that either support or refute these statements? Personally, I am having difficulty figuring this out based on my own experiences. In the past several months I have lost a significant amount of weight from cutting down my daily calories to about 1600/day. I still eat the same foods, just less. I am proof that you can lose weight eating “bad” foods. Ive been lifting but cant tell if Im gaining muscle because I dont know what the ratio of fat to muscle was/is. Thanks for the great info.–C.L.

What about some things around the ketogenic diet?

I’m well aware that any diet works simply because its less calories in then the body burns. This one seems a bit different since its focus is to have you enter a state of keytosis where the body and brain run on fat(keytones) over sugar. It was originally used to treat epilepsy but wouldn’t it also make it easier to burn away abnormal fat using this method?

Hi there…

I’ve seen a product claiming to be an HGH stimulator, with it’s primary ingredient being Gamma Aminobutyric Acid.

Here’s a quote with the study it references…

“A Study at the University of Milan, Italy showed “In 19 subjects studied, compared with 18 controls, plasma growth hormone levels were significantly increased (above 5mg/ml) by acute oral administration of 5 g of Gamma Aminobutyric Acid”

“This study showed over 550% increase in plasma growth hormone levels 90 minutes after Gamma Aminobutyric Acid Administration a significant increase unmatched by any other nutritional means.”

Reference:
Effect of acute and repeated administration of gamma aminobutyric acid (GABA) on growth hormone and prolactin secretion in man. Acta Endocrinol (Copenh). 1980 Feb; 92(2): 149-54″

Also, dosage instructions recommend taking it before bed, which to me suggests most of the measurable difference would simply be a decrease in resting insulin levels as you enter a more fasted state?

John Barban

These are all good claims.

I think we can tackle them over the next few podcasts.

We’re going to start with the high intensity interval training vs steady state cardio for weight loss. Might be able to get a couple other of these in there as well. But we can get all of these covered in the near future…stay tuned!
