Review: Revolution's Thermogenic Push for Women

Revolution's Thermogenic Push is a "extreme fat burner" for women, and is advertised to...

Boost the metabolismIncrease energySuppress appetiteProvide mood supportReduce water retention

This, of course, is the standard series of claims made for just about any weight loss product targeting women. But there are problems with making too many promises; given the logistics of capsule size and the required minimum effective dose of the appropriate ingredients, most of the time it's next to impossible to deliver on all of them.

And, by creating a product that promises to be "all things", the retailers dilute the overall effectiveness of the product because they can't focus on a single element of the formula.

So let's take a closer look at Thermogenic Push for Women and see if that's the case.

One capsule contains 408 mg of ingredients—and there are 11 of those in total. Recommended dosage is 2 caps in the morning, and 1 cap later in the afternoon. Given the large number of ingredients and relatively small serving size, it's not unreasonable to assume most ingredients will not be present in a dosage strong enough to elicit any effect.

For some ingredients, this will be fairly obvious, but not so for others—since Revolution does not provide a detailed breakdown of the ingredient profile. In other words, we don't know which ingredients are included at what dosages.

Anyway, let's take a closer look at them...

Dandelion root: This ingredient is included as a diuretic—therefore addressing the "water retention" claim. And yes, there is some preliminary evidence it works in this regard. However, products that are focused on water loss contain either a significant amount of dandelion root (250-500 mg and up), or combine it with other natural diuretics. At the two capsule dosage, Thermogenic Push may contain enough dandelion root to elicit an effect, although we cannot verify that for sure. Green tea extract: Green tea exhibits numerous characteristics that make it a helpful supplement for weight loss, although its effects are extremely exaggerated. Like all supplements, it needs to be standardized for the appropriate compounds and be present in a potent enough dosage to offer any effect. The retailers of Thermogenic Push don't reveal what they've standardizing their tea for, and how much ingredient is included. It's value, therefore, is somewhat debatable. Caffeine: The obvious energy booster in this formula; caffeine has a well established record as a mild thermogenic, and does deliver mild weight loss results (see Am J Clin Nutr. 1989 Jan;49(1):44-50, Am J Clin Nutr. 1980 May;33(5):989-97). It also cheaply and effectively addresses the most common complaint of dieters; lack of energy.White willow: A natural source of salicin, an anti-inflammatory similar to aspirin. In the old days, white willow was used as an alternative to aspirin in the ephedra / caffeine / aspirin stack. In non-ephedra based fat burners like this one, white willow offers no demonstrated benefit beyond that as an anti-inflammatory. Hoodia: An African succulent advertised to suppress appetite and enhance weight loss. I say "advertised" because there is no clinical evidence to validate these claims. Plus, there are additional problems with hoodia which may call its effectiveness into question. Yohimbe: From our glossary...

"The bark of Pausinystalia yohimbe, a tree indigenous to Western Africa. The active ingredient in yohimbe is the alkaloid yohimbine. Yohimbe bark extracts are often added to fat loss supplements and/or “male” enhancement supplements, although the amount of yohimbine is variable, and often low."

Yohimbe also possesses stimulant qualities, which may enhance the "energy-boosting" effect of the caffeine in this product. There have been studies performed on its weight loss characteristics, for which of course, it is used in this formula. Study results have been less than stellar: they range from showing no effect at all (J Pharmacol. 1986 Jul-Sep;17(3):343-7) to a slight improvement. This study concluded...


"The results obtained warrant further research on the applicability of alpha 2-receptor inhibitory drugs as a supplementary management in the treatment of obesity."

Evidence does validate yohimbe's "lipid-mobilizing action", however.

N-acetyl-l-tyrosine: In large doses (100-150 mg/kg of bodyweight) tyrosine helps with cognitive stress and fatigue (see here and here!). It's often added to weight loss supplements on the basis that as a precursor to the thyroid hormone thyroxine, it may elevate thyroid levels, and consequently, the metabolism. There is little evidence this is the case however. Evodiamine: Several thermogenic products I've investigated recently include Evodiamine, a compound derived from the Chinese fruit Evodia Rutaecarpa.

It's claimed to burn fat by increasing the body's production of heat, as well as reducing the body's ability to store fat.

Although a preliminary animal study shows promising results, to date there's no evidence showing evodiamine works in people.

Cayenne powder: At extremely large doses (3-10 grams) evidence suggests cayenne can elevate the metabolism, reduce appetite and decrease fat intake (see study abstracts here, here and here as examples). At the dosage included here, we doubt it will do anything much. Vinpocentine: An alkaloid derived from periwinkle that affects cerebral blood flow, memory and learning. Vinpocentine is often added to pre-workout, stimulant blends designed to improve focus, concentration and training drive. It does not need to be present in a large dosage in order to work, however; most effective products only contain 10 mg of ingredient. 5-HTP: Also known as 5-hydroxytryptamine and derived from Griffonia simplicifolia, it is used as an alternative treatment for depression, and, at a much larger dosage (900 mg/day) as an aid for weight loss and appetite suppression.

And there you have it; the entire Thermogenic Push formula deconstructed.

How's it measure up?

At the risk of sounding like a broken record, this is a difficult formula to analyze effectively since a complete breakdown of each ingredient's potency is not revealed. Ingredients like vinpocentine, 5-HTP, caffeine, dandelion root and green tea may be present in dosages high enough to provide some benefit, but it's impossible to tell.

Other ingredients are much less likely to be included at the dosage shown helpful in various clinical studies (if the ingredients are listed in decreasing order of amount, as they are supposed to be).

Since Revolution is charging a premium price for their product—$40 for a month's supply at BodyBuilding.com—we feel they need to come to the table with some specifics—anything to justify the cost they are charging.

For a vastly reduced cost you can buy each of the three ingredients most likely to be present in a useful dosage, and stack them together...

... and probably get 90% of the benefits for a third of the cost. Despite the slick packaging and cool name, there's not a lot here to justify the elevated cost.

Review: Hydroxycut Shape For Women

Hydroxycut Shape is the "professional strength weight loss formula" for women. According to the advertising I viewed...

"Fast weight loss is important to professionals who make their living looking good in front of the camera, on the stage or on the set – being in shape is their livelihood. That’s why there is Professional Strength Hydroxycut Shape – the professional solution for weight loss with key ingredients clinically proven in 8- and 12- week studies. Use as part of your healthy, active lifestyle including your nutrition and exercise program."

After reading this, I imagine you're wondering...

Are Vegas showgirls, Broadway actors and dancers and Hollywood starlets using "Shape" to stay in shape? And have the key ingredients actually been "clinically proven" as the good folks at Iovate / Muscle Tech insist they have?

To answer these questions, let's take a look at the ingredient profile, and especially the "W8 Lean™ Complex", a blend of four ingredients advertised as being proven in two clinical trials.

Incidentally, this exact same foursome of ingredients is labeled as the "HydroxyPro" complex in the Hydroxycut Hardcore Pro series fat burner.

In addition to a peppering of calcium, Vitamin C, folic acid and iron, two capsules contain an under-whelming 383 mg of ingredients, divided up between the following...

 L-Carnitine Tartrate: Carnitine has been a common ingredient in weight loss supplements almost since the time when dinosaurs roamed the earth.

And that's despite the fact that clinical evidence validating its effects is contradictory, even when consumed in multi-gram doses. Quite simply, the carnitine in this formula is present only as label dressing—it's present at a dose much too low to offer any effect.

Caffeine: Caffeine is a well known thermogenic with a proven track record of modest weight loss (see Am J Clin Nutr. 1989 Jan;49(1):44-50, Am J Clin Nutr. 1980 May;33(5):989-97).

Almost every stimulant-based fat burner on the planet contains it for this, and a couple of other good reasons—its cheap, and it effectively addresses the fatigue so many people feel contributes to their inability to execute and maintain an exercise program.

According to the product labeling, this product contains 200 mg of caffeine per serving, which means you'll be consuming a whopping 600 mg per day when you're up to the full 6 caps per day.

That means that this is not a product for those of you who are sensitive to stimulants, or who have an underlying health issue like heart disease, high blood pressure and so on. It also means you'll definitely "feel" this product—the caffeine in this product will definitely provide you with a "boost" of energy, if that's what you want.

W8 Lean™ Complex: Ah, here's that blend of 4 ingredients responsible for the "amazing" weight loss effects of this product. They are Alchemilla vulgaris extract, Olea europaea extract, Cuminum cyminum extract, and Mentha longifolia extract.

And are they "clinically proven" as claimed?

Sort of. While the folks at Muscle Tech / Iovate aren't revealing the study they are referencing for us to verify, there has been a study published on this quartet of ingredients that we can check out.

According to the advertising, participants lost an average of 20.94 over a 12 week period; not particularly impressive when you consider that equates to 1.75 lbs. of weight loss per week (well within the realms of what you can accomplish on your own with proper diet and exercise), and participants were restricted to a calorie reduced diet.

The devil, however, is in the details.

In this case, the details make it difficult to allot a ton of credence to the study results. For example...

1) The participants in the study did not have their caloric intake restricted or monitored. Instead, they were asked only to restrict their meals to three per day. Since the calorie value of meals can vary dramatically depending on your food choices, this essentially places each individual into his/her own unique study group—as no two participants will consume exactly the same amount of calories.

Think about it: if you know participants are still over-consuming calories in a significant amount, yet losing weight, that makes these ingredients significantly more valuable. If participants are under-consuming calories, that undermines the study results, does it not? Fact is, if you don't know how many calories your audience is consuming, it's impossible to accurately attribute any success or failure to a series of ingredients.

2) This study was not placebo controlled. In other words, the folks in the study group taking the product knew that they were, while the folks in the control group received nothing.

This is a big deal.

Folks taking the product may have seen it as a license to eat more (or perhaps less). The folks in the control group had very little incentive to stick to the straight and narrow.

As we both know, the placebo effect is very real, which is why any good study puts both the study group and the control group on a pill, with neither of them knowing who is getting the real thing.

I can't see any reason why this wasn't done in this case... unless you want to tip the scales towards a favorable outcome, that is.

In other words, all this study does is indicate the need for a properly controlled and monitored one to further confirm or dispel the claims that this quartet of ingredients actually "works". Perhaps the studies referenced by Muscle Tech used better methodology (if they exist at all), but since we can't examine it, we'll never know, right?

Gamma-oryzanol: A group of constituents derived from rice oil bran. Normally, it is included in supplements to lower cholesterol or raise testosterone and / or hGH (human growth hormone) levels. Clinical evidence supporting its use however, is extremely scarce.    L-ornithine HCl: An amino acid, also used to boost hGH levels and athletic performance. However, clinical data does not bear out ornithine's hGH-boosting effects (see Int J Sport Nutr. 1993 Sep;3(3):290-7). 

And that, my friends, is the Hydroxycut Shape for Women formula in all its "glory".

The core of this product is the combination of its caffeine content and the quartet of "clinically proven" ingredients, which as you now know, are clinically proven by a study that has some serious issues with its methodologies.

And, even if these results stood up to real scrutiny, it's not like the results were revolutionary; 1.75 lbs. a week is on par with what you can accomplish with proper diet and exercise.

Well, if you've enjoyed previous Muscle Tech / Iovate offerings (like Hydroxycut Max, for instance) you'll probably enjoy this product simply for its caffeine content. But caffeine is cheap (you can buy an entire bottle of 200 mg tabs for around $5) and that on its own hardly justifies the cost of a purchase.

And in our opinion, Muscle Tech hasn't proven the "quartet" of special ingredients provides any more than the mildest weight loss benefits (if any at all), and therefore we'd argue they don't deserve your money. Of course, we can't prove a negative, and it's possible we're wrong... but we highly doubt it.

And if you happen to be a Vegas showgirl, Broadway actor or dancer or a Hollywood starlet... sorry, there`s no magic pill here.

Why don't you tell us what you think? Have you used the new Muscle Tech Shape offering? What did you think...
