GNC Weight Loss System Review - 6 Things You Need to Know

GNC, a giant within the supplement sales community, offers a ton of products intended for fat-burning and weight loss. GNC claims that their branded products, including those under the Total Lean umbrella, are as effective as any other product on the market. However, many of their weight-loss product include Waterex, a diuretic, which not only promotes dehydration but also gives users a false sense of weight loss.

We wanted to do our own evaluation of GNC’s weight-loss system, so we did a thorough investigation into the products in their line and the research behind them. We then condensed all of this information to give you the bottom line.

GNC Weight Loss System can be purchased through their Official Site.

What is GNC Weight-Loss System?

Firstly, GNC Weight-Loss products do not have any specific ingredients because they include many products. Some of them include, Burn 60, Lean Shake Burn, and conjugated linoleic acid (CLA). Stimulants are often used, but this isn’t a new thing and stimulants, like caffeine, have been shown to have positive effects on cognitive performance, and memory, according to Current Neuropharmacology.

The effects of CLA on weight and metabolic rate aren’t as clear cut. For instance, a 2015 study published in the journal Nutrition & Metabolism ascertained from a collection of studies on CLA, ” … clinical evidences accumulated thus far show that CLA is not eliciting significantly promising and consistent health effects so as to uphold it as neither a functional nor a medical food.”

All of these GNC Weight-Loss pills are manufactured and sold by General Nutrition Centers, which was established by David Shakarian. They sell a wide variety of supplements, ranging from herbal remedies to protein powder, and vitamins. The prices for their supplements usually start around $40 and can increase up to $190 or more. However, they do have a lasting impression in the market as a reliable seller of health products.

The GNC Weight-Loss System is also known as the GNC Total Lean Starter Kit.

Lack of Weight-Loss

The first issue we had with GNC Weight-Loss Systems was their lack of results, according to some customer reviews. “When people spend their hard earned money on a product, the last thing they want to happen is for it not to work,” says our Research Editor. “That is a complete disappointment.”

According to one customer who used GNC Weight-Loss supplements, “These pills made no discernable difference with regard to weight loss, calorie burning or appetite suppression – and I have gained a few pounds while taking them.”

“This product did not work for me,” another agreed.

Everyone didn’t feel this way, however. One person wrote, “…[I] am very pleased with the results.”

Another individual said, “It REALLY WORKS!!! AWESOME AWESOME product!!!”

Side Effects

Negative Side Effects

The second issue we had with GNC Weight-Loss System was some of its reported side effects. “One of the most common problems we see with any supplement is the issues customers experience while taking it,” says our Research Editor. “No one wants to use a product that has all pain and no gain.”

“At first this product worked for about four days I had more energy, curbed appetite, then I started to become irritable, nervous, tired, and nauseous to the point I couldn’t even sit up without feeling sick,” mentioned one customer.

Another agreed, saying, “I took this one time and it made me SUPER SICK.”

However, these side effects didn’t affect everyone. According to one review, “I’ve tried nearly every popular thermogenic/fat-burner on the market over the past 20 years, and while some may have more kick to them (and usually with bad side-effects), [this supplement] is the best balanced product of its kind.”

“…there was no shaky/antsy/jittery effect…” mentioned another.

After reviewing hundreds of supplements, we at DietSpotlight found that all it takes is something like negative side effects to push customers away and ruin that chance of lasting success. If GNC Weight-Loss shakes and pills have this problem, it can be a major issue for the consumer as well.


The Science

Although we do know that some of the ingredients found in GNC Weight-Loss System have some science backing them, the company claims that all are clinically studied.

However, when you look at the research they provide, it says that the test was performed on one GNC multivitamin and the results showed that it increased levels of vitamins and minerals in the blood system.

Unfortunately, this does no back up their other products. At DietSpotlight, we like to see some support before we give a recommendation, and in this case, we aren’t so sure there is enough.

What Users Are Saying

“Works great. Longer workouts, easier days at work, no afternoon crash and lost 30 lbs so far with this product. I’ve burned 30 going for Burn 60.”

“This doesn’t give me the energy I wanted and it also sometimes makes me feel nauseous if I don’t eat something before I take it. Overall it’s ok but I think I’ll stick with regular CLA minus the caffeine because again it didn’t give me the jolt I was looking for and the nausea was awful. I’ve lost a few lbs but I also exercise and eat pretty clean so can’t chalk it up to this.”

“I haven’t seen any weight lost in over 2 months but I love the taste! I mix it with almond milk and it gives me extra energy so that I can get my workout in… not sure if I agree that it helps me burn more calories though”

Bottom Line

Bottom Line on GNC Weight-Loss System Work

So, should you race out to get one of bottle of GNC Weight-Loss pills? Well, we do like that the company has been around for quite some time and that they offer a variety of health supplements. However, when we looked at the science, side effects, and results, we became hesitant to give this our recommendation.

If you are ready to lose weight, then we think you should try a product that produces real results and is backed by significant science. Also look for customer reviews that talk about real, lasting results.

Among the best products we’ve seen this year is one called Noom. It is a weight-loss program with tools that work to help men and women lose weight and maintain that weight loss for lasting results.

Plus, the company is offering a free trial of Noom, something we think you should check out.
