Recent Research in Science on 4 Popular Fat Loss Supplements

Fat Loss Supplements
Burn fat fast. Crank up your metabolism. Get a beach body by summer.

You've read the hyperbolic promises fat loss supplements often make, accompanied by before-and-after pictures of a former obese person who used that product and now looks absolutely fabulous.

Then you read the small print. Maybe that "miracle supplement" isn't such a miracle after all...

Rather than rely on buzz or savvy marketing, I looked at the science behind four popular fat loss dietary supplements. Will they increase your metabolism or otherwise help you lose fat fast? An emphatic perhaps is my short answer. Read on.

Green coffee bean

What is it?

An extract present in raw coffee. The polyphenol antioxidant chlorogenic acid (CGA), also found in a few fruits and vegetables, seems to provide most of green coffee extract's (GCE) benefits. Extracted GCE becomes frequently marketed as a weight loss supplement. Among its purported benefits include decreased gut glucose absorption and decreased glucose accumulation after meals.

What do the actual studies say?

Studies have been fairly favorable about supplementing with green espresso extract (GCE).

One mice study found GCE possibly effective against putting on weight and fat accumulation. Another mice study showed decaffeinated green coffee enhances diet-induced insulin resistance and brain energy metabolism.

Fewer human studies regarding GCE exist. One 22-week randomized, double-blind, placebo-controlled, linear dose, crossover research using GCA (a brand of GCE) found GCE can help reduce "weight within preobese adults, and may be an inexpensive means of preventing obesity in overweight grown ups. "

And a meta-analysis that reviewed three eligible clinical human trials discovered "a significant difference in body weight in GCE compared with placebo. " However , experts found every study they reviewed "associated with a high risk of bias" along with poor methodological quality.

Studies show humans absorb and metabolize chlorogenic acid along with other nutrients in GCE very well.

My thoughts

Studies appear promising about eco-friendly coffee extract (GCE). I wouldn't expect any miracles on its own, but coupled with an intelligent eating plan that addresses food intolerances, GCE might become that needle componérselas to overcome plateaus and nudge you towards fat loss.

Conjugated linoleic acid (CLA)

What is it?

A naturally-occurring fatty acid found in many dairy products and meat. Amongst CLA's purported benefits as a dietary supplement include improving fat loss.

What do the research say?

Most have been positive. Some show CLA can help decrease body fat bulk and increase body lean mass as well as reduce fat accumulation.

CLA appears to target abdominal (belly) fat -- the type of stubborn, won't-vacate fat we all would like to get rid of.

Several longer-term studies confirm those benefits. A one-year double-blind, placebo-controlled study found long-term CLA supplementation helps reduce body fat mass (BFM) within healthy overweight adults, while another study found CLA could prevent vacation weight gain and "significantly reduced body fat over six months. "

Getting the right quantity of CLA becomes crucial here. One meta-analysis found supplementing with 3. two grams of CLA daily creates modest fat loss in humans.

Some experts express concern about potential adverse effects using CLA, including lipid profile, sugar metabolism, and insulin sensitivity. Yet for most people, CLA seems safe at the suggested dose.

My thoughts

Patience and taking the right amount become crucial along with CLA supplementation. Don't expect dramatic overnight changes, but combined with a smart eating and working out, supplementing with CLA might provide a favorable nudge on the scales. To get the three. 2 grams the above study recommended, you'll need to take four or five soft gels every day.

Garcinia Cambogia

What is it?

Perhaps the most-hyped supplement currently on the market, mostly due to "Dr Oz how to lose weight" calling Garcinia cambogia "an exciting breakthrough in natural weight loss. "

The Garcinia cambogia plant's skin contains hydroxycitric acid (HCA), that seems to provide most of the supplement's benefits.

While marketed as a fat-loss supplement, experts aren't entirely clear how HCA works. Some speculate it increases body fat breakdown, others that it down-regulates obesity genes; still others believe HCA may increase your feel-good neurotransmitter serotonin to suppress appetite.

What do the studies state?

Almost all involve animals. One using high-dose Garcinia cambogia found it under control fat accumulation in obese rats but also created toxicity in the testis. Later on reviews found design flaws in this study and argued the HCA utilized may have been contaminated.

Regardless, human studies haven't been as promising. Researchers in a single review found little evidence to support using Garcinia cambogia. Another randomized manage trial with 135 people concluded, "Garcinia cambogia failed to produce significant weight reduction and fat mass loss beyond that observed with placebo. "

The meta-analysis using nine studies found small but statistically significant difference in weight loss within the HCA group. Researchers concluded cost of garcinia cambogia extract and HCA can be the benefit of short-term weight reduction, although one study noted gastrointestinal side effects occurred twice as often in the HCA team.

Garcinia cambogia seems to work best combined with other nutrients. One very recent research that combined Garcinia cambogia with Ascophyllum nodosum extract and l-carnitine came to the conclusion these nutrients as a team could suppress appetite.

My thoughts

Combined with other nutrition as a synergistic fat loss formula, Garcinia cambogia might become beneficial, though research don't support those benefits using it alone.

Raspberry Ketones

What is it?

Rheosmin or even raspberry ketone resembles capsaicin and synephrine, two compounds that favorably change fat metabolism. Reported benefits as a supplement include fat loss and improved lean muscle mass.

What do the studies say?

Almost all raspberry ketone studies involve animals. 1 involving mice found raspberry ketones prevented fat accumulation and increased body fat breakdown in fat cells. Another rodent study showed raspberry ketones assist break down fat.

In both studies, researchers fed these rodents massive amounts of raspberry ketones -- potentially impractical or unsafe to replicate on humans -- to get those effects, and no human studies using raspberry ketones alone can be found.

One human study did use a branded product that combined raspberry ketones with other weight loss aids like caffeine and ginger.

Researchers found beneficial body-fat changes in the overweight men and women who used this product compared with the placebo, though we are going to not sure whether raspberry ketones or another component provided those benefits.

My ideas

As a supplement, raspberry ketones seem to have the most effect when combined with some other nutrients to create a synergistic fat loss supplement. Even then, I would hardly consider it the actual "miracle supplement, " as some folks describe raspberry ketones.
