18 Shake vs GNC Total Lean Shake Review

18 shake vs gnc total lean shake review

“Why should I buy 18 Shake, when GNC Total Lean Shake curbs my hunger twice as much and provides more vitamins?” That’s what Tom, one of our newest readers, asked. This question gave us food for thoughts and we decided to answer him and all the other people who ask themselves: “Which supplement is better: 18 Shake or GNC Total Lean Shake?”

To determinate which meal replacement shake is better, we have to consider various factors. Including the ingredients…

What about the ingredients in both weight loss shakes?

We don’t have to explain you how essential it is to reduce calorie intake, when you want to lose weight. 18 Shake is a great help with 90 calories per serving, whereby GNC Total Lean Shake offers aroun 180 calories in one protion.

That’s twice as much as 18 Shake. The sugar and fat content in both shakes isn’t supporting GNC Total Lean Shake reputation. 18 Shake contains 1g of fat and sugar in one serving. GNC Total Lean Shake on the other hand, contains 4g of sugar and 2g of fat per protion.

Doesn’t look good for GNC Total Lean Shake, but maybe our next question is going to give GNC a opportunity to catch up…

How much proteins do the supplements offer?

18 shake vs gnc total lean shake review

One portion of GNC Total Lean Shake contains 9g proteins from three different sources: Milk, whey protein concentrate and whey protein isolate.

Whey protein is a special protein that is favored by athletes, because of its high amino acid content. Whey protein is ideal for you, if you want to lose bodyweight without reducing your muscles.

18 Shake doesn’t have milk proteins, but also offers whey protein isolate and whey protein concentrate, therefore it doesn’t lack essential amino acids. Furthermore one serving of 18 Shake contains 15g of proteins! That’s pretty good, even if you compare it with other meal replacement shakes like 310 Shake.

Now let’s take a look at the dietary fiber in both substitutions.

How much fiber can I expect?

Fiber is essential to keep your metabolism healthy and curb your hunger, therefore no meal replacement shake should lack it.

18 Shake validates his good reputation again with a dietary fiber content of 15g per serving. A recent study has proven that 10g of diatery fiber per day improve weight loss significant. GNC Total Lean Shake disappoints again with only 8g of fiber per portion.

Still think GNC Total Lean Shake is better than 18 Shake, Tom? 😉

Which shake contains more vitamins and minerals?

This round goes to GNC Total Lean Shake. 18 Shake provides you with 18 essential vitamins, but GNC Total Lean Shake offers 20 vitamins. The health beneficial effects of all these vitamins and minerals range from weight loss support and cancer prevention, to a better mood and more energy.

Here is a list of all ingredients that can be found in 18 Shake and GNC Total Lean Shake:

Now we will discuss another essential question, when deciding what meal replacement shake you want to buy:

How long do the shakes curb my hunger?

The high amount of calories in GNC Total Lean Shake is a clear advantage now. Most customers felt satisfied for 3-4 hours after drinking 18 Shake, but GNC Total Lean Shake curbed the hunger of most people for 5-6 hours.

Well, that’s a big point for GNC, considering the fact that people often fail their diets, because the temptation to eat junk food or unhealthy snacks is too big.

Are the supplements vegan, gluten- and GMO-free?

GNC Total Lean Shake fulfils all of these points. Unfortunately 18 Shake doesn’t offer a vegan version. At least both supplements are GMO- and gluten-free.

Is one of these shakes backed up by science?

GNC Total Lean Shake is supported by a study that showed significant more weight loss by participants who consumed GNC. Sadly we couldn’t find any studies regarding 18 Shake.

Nevertheless, there are countless clinical studies proving the weight loss promoting capabilities of meal replacement shakes like 18 Shake and GNC Total Lean Shake.
