Quick Fat Loss

Doesn't live up to claims

I’m not convinced Sleek and Lean is a highly-effective diet pill. It has several ingredients proven to reduce fat or weight. However, the proven dosages must be used, and I’m doubtful they are.

Several users said the product is effective. But these people also exercised and ate healthy diets. These 2 factors alone are enough to cause weight loss.

If you take 6-9 capsules daily, Sleek and Lean only lasts 13-20 days. This product is overpriced. I recommend you buy a different diet pill — one that is more affordable and effective.

Ab Cuts Sleek and Lean is the newest product from Revolution. It’s similar to the original Ab Cuts Midsection Formula. However, Sleek and Lean includes proven ingredients to enhance users’ weight loss.

Usually, the ingredients Revolution uses promote fat loss; not weight loss. Since Sleek and Lean contains proven ingredients, it may actually help people shed fat and weight. So, is Sleek and Lean worth trying?

What Are the Ingredients?

Sleek and Lean does not contain stimulants. In fact, no Revolution product does. This distinction earned Revolution GNC’s #1 Non-Stimulant Brand award for the past 3 years. Here are Sleek and Lean’s non-stimulant ingredients:

Conjugated Linoleic Acid. CLA is a polyunsaturated fatty acid. Multiple studies involving CLA show it reduces body fat and builds lean muscle.[1][2][3] Unfortunately, CLA does not cause weight loss. Instead, it improves body composition.

Raspberry Ketone. Red raspberries get their aroma from raspberry ketone. This enzyme regulates metabolism and breaks down fat cells. It also prevents the body from absorbing and storing fat. Researchers say raspberry ketone promotes weight loss.[4] Dr. Oz calls it a “miracle fat burner.”

L-Carnitine. Many companies advertise L-carnitine as a weight loss ingredient. However, UMMC says there is no research to prove L-carnitine is effective. It may burn fat and increase muscle, which indirectly leads to weight loss in some people.[5] In a rat study, L-carnitine had no effect on weight.[6]

Coleus Forskohlii. Forskolin is the active ingredient here. Researchers believe it triggers chemical reactions which break down fat. This causes fat loss and weight loss. However, studies are inconclusive. One study showed coleus prevents weight gain, but doesn’t promote weight loss.[7] Another study found it does reduce weight.[8]

Borage Oil. This oil contains Gamma Linolenic Acid (GLA). It’s an omega-6 fatty acid, which enhances brain function. GLA may reduce nerve pain and inflammation as well. In 2007, researchers showed GLA prevents weight gain.[9] But there are no supporting studies.

Flaxseed Oil. Lignans control blood sugar, lower cholesterol, and improve insulin sensitivity. Flaxseed oil contains many lignans. Some studies link lignans to faster metabolism and fat loss.[10] But so far, researchers haven’t proven flaxseed oil produces the same benefits.

Fish Oil. The DHA and EPA in fish oil prevent heart disease and reduce cholesterol. They also keep skin healthy and boost the immune system. But whether they help people lose weight is still in question. It’s believed fish oil prompts the body to burn fat stores faster. However, a recent study revealed fish oil is not effective for weight loss.[11]

Sesame Seed Oil. Sesame seeds are packed with nutrients and healthy fat. Both the nutrients and fat may increase satiety, but you have to eat a large amount. Unfortunately, sesame seed oil is high in calories. So, consuming a large amount may be counterproductive. No scientific evidence links the oil to weight loss.

Vitamin E. Antioxidants neutralize toxins and free radicals that damage cells, speed the aging process, and may decrease metabolism. Vitamin E is a powerful antioxidant used in skincare products. Many people believe it also strengthens muscles and improves exercise performance. However, there are no proven ties to weight loss.

Are the Proper Dosages Included?

Sleek and Lean bottles hold 120 softgels. Revolution recommends taking 2-3 softgels before every meal. That’s 6-9 softgels per day. Each softgel holds 735 mg.

Because the company hides the individual dosages in a proprietary blend, I don’t know if Sleek and Lean contains the proper dosages or not. All I know is if you take 6-9 softgels daily, you’ll consume 4,410-6,615 mg. These amounts seem large, but they may not be large enough.

Study participants consumed 3,200 mg conjugated linoleic acid every day to prevent weight gain.[1] Borage oil, flaxseed oil, and fish oil studies also used 1,000-3,000 mg dosages. So, it’s possible Sleek and Lean does not contain all the proven ingredient dosages.

User Ratings and Reviews

GNC.com currently features 51 user reviews. The average rating is 4.3/5 stars, which is very good. 89% of reviewers said they would recommend Sleek and Lean to others.

Here’s what users said about Sleek and Lean:

Effectiveness

Sleek and Lean is effective for weight loss or weight maintenance. The best results come when you combine the product with a healthy diet and regular exercise. Taking so many pills a day is inconvenient though.

Only 6 people said Sleek and Lean was not effective. Also, many people said the pills taste or smell bad, and the product is overpriced.

Side Effects

The Sleek and Lean ingredients are safe. However, CLA, borage oil, flaxseed oil, and fish oil are known to cause side effects. Users reported gas, digestive problems, diarrhea, and bad breath. But these side effects were usually temporary and didn’t affect most users.

Where to Buy Ab Cuts Sleek and Lean

The Revolution official website does not sell Ab Cuts Sleek and Lean. I was surprised by this because it’s their newest product. Luckily, I found listings on several reliable sites:

• GNC.com: $59.99
• Drugstore.com: $58.99
• LuckyVitamin.com: $44.99

These sites do not have money back guarantees. But you may be able to return unopened Sleek and Lean bottles within 30 days.
