Non-Stimulant Diet-Support Solutions
For the Stim-Sensitive Athlete

For many of us, diet support is easy. If you have what could be described as a "normal" tolerance to stimulants, you're good to go when it comes to most "buzz worthy" thermogenic diet-support supplements. In fact, one particular thermogenic weight-loss supplement that has long been acclaimed as the category leader for its advanced and super-comprehensive matrix of transformative mechanisms of action has just been newly amplified for even more weight-loss power. But BioQuest's new BetaStax Elite is a story for another day.

Diet Support Without the Buzz
Today, we're talking non-stimulant alternatives. How do you know if you're stimulant sensitive? Well, we're not talking about that alert, amped-up feeling that many of us enjoy, particularly as we're walking out onto the gym floor in anticipation of a great workout. Symptoms for those who might be better off avoiding typical thermogenics include the onset of dizziness or nausea, heart palpitations, and difficulty sleeping (no matter how many hours have elapsed since your last thermogenic dose). Clearly, this outcome does not apply to your typical athlete. But for those of you out there who do experience these symptoms, this article is for you.

If you're sensitive to stimulants, your choices are more limited, though the best options still pack a powerful punch. This is also a good place to note that non-stimulant diet-support options are not just for the stimulant averse. Many athletes use these products in combination with thermogenics to attack excess fat via as many pathways of action as possible. A stack like this BetaStax / Tonalin CLA offering will pay real dividends for an athlete looking to get lean and rock-hard. So now, let's take a look at some noteworthy supplements that will address excess fat without the amperage.

Conjugated Linoleic Acid (CLA)
Conjugated Linoleic Acid (CLA) is a naturally occurring Omega-6 fatty acid found primarily in meat and dairy products. Bodybuilders have long valued CLA for its unique capacity to help effect body repartitioning via a combination of excess fat reduction and lean-muscle support. And, just as importantly for our purposes here, it is a common non-stimulant ingredient in diet-support products.

So, just how effective is CLA at supporting body repartitioning? In one of the largest and best controlled studies of CLA, researchers from Norway examined the effects of CLA supplementation (3.4 g/day) on whole body and regional composition in overweight men and women. The study used a double blind, randomized, placebo-controlled design in over 100 subjects. The study lasted 6 months during which time subjects were instructed to maintain their normal diet and exercise patterns, the only major change being to supplement with either CLA or placebo. After 6 months, the CLA group lost significantly more body fat (-3.3 pounds) compared to a gain of 1 pound in the placebo group. Further, the CLA group gained 1.3 pounds of lean body mass, whereas the placebo group had little change (+0.4 pounds). In summary, the placebo group had little change in body composition as expected, but simply taking 3.4 g/day of CLA without making any other lifestyle changes resulted in simultaneous fat loss and gain in lean body mass.1

In another study, researchers reporting in the Journal of Nutrition found that CLA supplementation to obese subjects can alter body composition in as little as 12 weeks. In this study, subjects made no other lifestyle changes other than consuming either CLA or a placebo. There were 2 groups of CLA that consumed a low dose (3.2 g/day) or high dose (6.4 g/day). Body composition measured by dual energy X-ray absorptiometry revealed that subjects in the high dose CLA group had a significant increase in lean body mass of one and a half pounds, and they lost about half a pound of fat. The increase in lean body mass with CLA occurred despite no changes in diet or exercise training.2

Clearly, these are exciting results. It should also be noted that of all the sources of CLA available to athletes, Tonalin CLA is far and away regarded as the industry gold standard. ProSource Tonalin CLA is a highly potent and pure premium-grade material that's standardized for an unprecedented 80% Tonalin CLA.

Green Coffee Bean Extract
Another promising non-stimulant technology is green coffee extract, which contains high concentrations of chlorogenic acids that have been associated with diet support by way of their ability to help modulate glucose utilization and fat metabolism. Unfortunately, you can't just brew up a cup of coffee containing these beans because they're exceptionally bitter and the high temperatures used to roast coffee beans damage the chlorogenic acids. To avoid this outcome, supplement manufacturers use concentrated extracts of green coffee beans, which contain higher amounts of bioactive chlorogenic acids.

Here again, the science supporting this non-stimulant mechanism of fat loss is persuasive. A 22-week crossover study was conducted to examine the efficacy of a commercial green coffee extract in reducing weight and body mass in 16 overweight adults. Subjects received high-dose green coffee extract, low-dose GCE, or placebo in separate six-week treatment periods followed by two-week washout periods to reduce any influence of preceding treatment. Treatments were counterbalanced between subjects. Primary measurements were body weight, body mass index, and percent body fat. Significant reductions were observed in body weight (-8.04 ± 2.31 kg), body mass index (-2.92 ± 0.85 kg/m2), and percent body fat (-4.44% ± 2.00%), for the high-dose GCE subjects, all with no significant changes to diet over the course of the study. The results are consistent with human and animal studies and a meta-analysis of the efficacy of green coffee extract in weight loss.3

As always, it's worth the effort to read the ingredient label of your green coffee bean extract supplement very closely, because chlorogenic acid content and quality varies widely by brand. ProSource's Green Coffee Bean Extract is unrivaled in power and purity, and is standardized for a potent dose of 50% chlorogenic acids (200mg).

Raspberry Ketones
Ever think of eating more raspberries to help increase your body's ability to burn fat?  It turns out a key ingredient found in raspberries has properties that a couple of preliminary studies suggest may help to increase fat breakdown and limit fat accumulation. Scientists originally became interested in raspberry ketones because structurally they are very similar to capsaicin, another common diet-support ingredient, but without capsaicin's spicy or pungent effect.  

The first study to examine the impact of raspberry ketones on its ability to prevent weight gain provided various doses of raspberry ketones to laboratory mice and fed them a high-fat diet.  The high levels of raspberry ketones in the animals diet helped to reduce weight gain and also increased the amount of lipolysis or fat breakdown in fat cells found in the animals.4

Several years passed before another study was conducted and recently scientists exposed fat cells to raspberry ketone in an effort to examine what exactly was responsible for the perceived prevention in weight gain and increase in fat breakdown as seen in the initial study. When exposed to fat cells, raspberry ketone significantly increased the amount of lipolysis or fat breakdown in fat cells.  A follow-up analysis revealed that raspberry ketones favorably increased the expression of adiponectin, an important hormone released primarily by fat cells.

Equally important, exposing fat cells to raspberry ketone decreased the amount of fat which accumulated in the fat cells, which is a favorable change linked to reduction in overall body fat.  The authors concluded that raspberry ketone holds great promise for its ability to both reduce fat accumulation and increase fat breakdown.5 Certainly, additional research is needed to further confirm these results in humans to see if they can be used as an aid to help lose fat and control your body composition, but the early results are encouraging.

Interested in trying this emerging new technology? Your best bet is ProSource's Razberi-K supplement. ProSource's premium-grade Razberi-K product contains only the highest quality Raspberry Ketones [4- (4-hydroxyphenyl) butan-2-one] in a 100mg dose.

Protein And More Protein
As most athletes are well aware, simply doing your best to support muscle tissue is, in itself, a valuable diet strategy because muscle is more metabolically active and may improve calorie expenditure, thus further supporting a leaner physique. Therefore, maximizing protein intake throughout your day is essential. Of course, not all proteins are created equal when it comes to body repartitioning. One protein, in particular, ProSource's Vectron, contains an elite fractionated protein complex called Prolibra, a specialized bioactive peptide matrix along with a special whey mineral complex designed to precisely target essential mechanisms of body transformation.

How effective is it? Let's take a look at the science. In an independent, randomized, double-blind, 12-week clinical trial published in the Journal of Nutrition and Metabolism, subjects taking Prolibra retained twice as much lean muscle while at the same time experiencing 79% fat-loss compared to the control group at 51% fat loss. Those are results you can really get excited about. Other proteins, such as ProSource's NytroWhey Ultra Elite, are also critical to supporting your workouts and recovery, and should form the cornerstone of your daily supplementation regimen.

And there you have it. Clearly the fitness-conscious, stimulant-sensitive athlete has plenty of options when it comes to attacking excess fat. So go out there and beat the bulge, without the buzz!
