Is garcinia cambogia (HCA) a legit weight loss agent? Is it safe? What dose is needed? Learn the FACTS in this video!
“You are what you eat” is an old expression your grandmother’s grandmother probably used, but it’s not actually correct technically speaking. Putting on my nerd hat to be a stickler for the details, it’s more accurate to say “you are what you absorb.” Grandma’s sage advice does a good job of illustrating that what we ingest is obviously essential to our health, but what we ingest that actually gets absorbed and utilized by the body is the crux of the issue truth be told.
The piles of studies that have been growing in recent years showing all manner of potential benefits of various nutrients has been very encouraging. We are experiencing an exciting time in nutritional science where new compounds are being discovered – and tested for their potential benefits – almost daily. Compounds that may help prevent cancer, improve immunity, improve weight loss, improve brain function, or improve athletic performance, to name just the tip of the iceberg of where science is currently looking to isolate and test various nutrients for their bio active properties.
How the process works:
Once a compound is discovered, it tends to get isolated, and then tested in either animal models and or in vitro (test tube) to test what positive or negative properties may exist as well as elucidate how they work. That is, understand not just what system they may impact (such as increase an animal’s ability to resist cancer causing chemicals for example) but also examine the isolated compounds’ “mechanism of action” which shows how it achieves the effect. How does that work? Let’s say some spice has been used for generations to reduce infections or improve immunity. Scientists might then feed, or inject, large amounts to lab animals (e.g., mice, rats, rabbits, etc.) and see if it does indeed have activity; perhaps testing how that spice reduces the size of tumors when the mice are exposed to known carcinogens, or bacteria known to cause infections and so forth. If that spice shows biological activity, scientists will often look deeper into that spice to see which specific constituent(s) in the spice are having the “active” compounds, and once found, will concentrate and isolate that active compound and further tests on animals, or humans, or in vitro (test tube) will continue. Foods and spices for example, are highly complex and can have hundreds or even thousands of biologically active compounds in them.
Or maybe both? In this vid I cover this controversial supplement and give science based advice. An extensive article that examines the study mentioned in this video on the effects of ARA on strength and muscle mass can be read HERE!
Whey protein has become a staple nutritional supplement with both athletic populations requiring the highest possible quality protein to help recuperate from exercise, and those interested in the various health and disease fighting benefits of whey.
However, whey is a complex protein which leads to various questions regarding this biologically active protein. Some of this confusion has stemmed from the marketing efforts of various companies competing for sales in a very competitive market. Some of the confusion stems from a simple misunderstanding of the science of whey.
This Q&A will attempt to address some of the most common questions regarding whey as it applies to some of the major differences between types of whey, such as whey concentrates and whey isolates and other common sources of confusion. For in-depth information on whey and its many potential health benefits, read the “50 Shades Of Whey”
Q1:“What are the essential differences and advantages/disadvantages of each type of whey protein? Isolate, concentrates?”
DHEA (dehydroepiandrosterone) is most known for being a pro-hormone which in the body gets converted to testosterone and estrogen. It is a long held view that DHEA exerts all its effects via conversion to testosterone and estrogen. However, recent studies show that DHEA also has several interesting non-hormonal actions…
In this vid I cover the essential points I covered in a lengthy article by the same name: absorption, solubility – as a key factor in absorption – and a new technology that improves solubility.
For those in the supplement industry especially, you’ll want to watch this vid!
Will has previously mentioned DHEA as it relates to hormonal effects and health promotion:
When it comes to health promotion and longevity, DHEA is a supplement which deserves more attention than it is getting.
DHEA levels (the main circulating form of DHEA in the bloodstream is DHEAS) decrease approximately 80% between ages 25 and 75 year.[1, 2] This large decline in DHEA has led to interest in the possibility that aging related DHEA deficiency may play a role in the deterioration in physiological and metabolic functions with aging, and in the development of chronic diseases.
In support of this, it has been reported that DHEA level is negatively correlated with mortality and risk of developing cardiovascular disease (CVD) (i.e. lower DHEA(S) levels are associated with higher mortality and CVD risk).[3-5] More recently it has been found that a steep decline or extreme variability over time in DHEA(S) levels is associated with higher mortality, more so than baseline DHEA(S) levels.
Aging not only reduces DHEA(S) levels, but also results in an increase in arterial stiffness [7, 8], which is an independent predictor of cardiovascular disease (CVD) risk and mortality.[9-11] It has been reported that DHEA levels are inversely associated with arterial stiffness (i.e. lower DHEA levels are associated with increased arterial stiffness. [7, 12, 13] Therefore, it is possible that DHEA replacement could reduce arterial stiffness, and thereby contribute to reduction in CVD and mortality…
As with fashion, what gets sold for supplements are often many decades old, and have been re marketed to people as new and “cutting edge.” . Case in point, Deer Antler products. Been around longer than I have yet made a big return to the market recently. It didn’t perform as advertised then, and it doesn’t now. Yet, millions of bottles sold sadly.
