The results of my research into Look Slim pills were somewhat surprising. We at DietSpotlight created one of our comprehensive reviews, examining the ingredients, side effects, customer-service quality and scientific studies. We additionally read hundreds of user responses and comments from all over the internet. Finally, we compacted all of the information we collected to give you the facts you need.

What is Look Slim?

To start, Look Slim is a capsule supplement for weight-loss. It’s available over-the-counter and can be purchased through the official website. This product is claimed to boost energy levels, burn off excess body fat and encourage stamina. [1] The key ingredient in this diet formula is raspberry ketone.[2] No caffeine or stimulants are used in this supplement. [3] You simply take two capsules each day between dinner and bedtime (with a glass of water). This should be done for 90 consecutive days.

Health Nutritional Supplements is the company behind Look Slim pills. There is no special diet or exercise program mentioned with this product. Both women and men can take this weight-loss formula, and there are some positive user comments posted on the web, but read on…

Fad Ingredients – “Concerned Yet?”

The first concern we have is with Look Slim ingredients. According to our Research Editor, “The only active component used in this diet supplement is raspberry ketone. Unfortunately, this fruit extract has not been proven to help with fat loss as often claimed.” [4]

One user reported, “This stuff does nothing at all. Took it for 30 days straight. No results whatsoever. I want a refund.”

However, a different user had this to say, “May help a little. I exercise regularly, so it’s difficult to tell if it’s the Look Slim pills.”

Another said, “Not sure yet. Been taking Look Slim capsules for about two weeks. I will give it more time.”

Minimal Results – “Not a Good Sign”

Another concern we have is with minimal weight-loss results. According to a number of customers, this supplement does not produce the fat-loss effects it claims to. For instance, one user revealed, “No Look Slim side effects. But, no fat loss either. I guess I will chalk this up to a $50 loss.”

But, a different person posted, “Seems okay. I like that it has no caffeine. I am combining it with diet and exercise.” [5]

“Gives me some abdominal discomfort. But, I think it’s helping me lose weight,” said another individual.

According to our research, if there is a certain facet of a diet supplement or weight-loss pill that’s very problematic (fad ingredients, minimal results, side effects) the odds of long-term success are not very promising. In other words, if Look Slim pills do in fact fail to produce real fat-loss effects in a lot of people, this could be a serious problem.

The Science – “Is There Any Presented?”

At DietSpotlight, we like to see some actual research or documented studies that support the weight-loss product we’re investigating. Sadly, we could not pinpoint any science that backs up Look Slim capsules and the marketing claims posted on the website. Therefore we only see a big red flag.

The Bottom Line – Does Look Slim Work?

Now the moment you’ve been waiting for. Here is our bottom line on Look Slim diet pills. First of all, we like that this supplement does not require a prescription and it’s easy to use anywhere. However, we have some doubts about this product because it’s not supported by any published clinical research. Furthermore, we’re concerned about the minimal weight-loss results that some customers have reported.

If you’d really like to get rid of some pounds, then we advise you to select a product that contains clinically tested ingredients for weight-loss, is backed by numerous user testimonials and comes with excellent customer service.

Among the best products we’ve seen in 2016 is one called Leptigen. This supplement uses a blend of four powerful ingredients, which have been clinically tested and are shown to help accelerate fat loss and ignite metabolism. We have not found any discouraging user remarks online, and comments around the web show people are seeing actual results.

The makers of Leptigen are so certain of their product they’re offering a Special Trial Offer, which is a good sign.

What You Should Know

Millions of overweight Americans are tired of structured diet plans that just don’t work. Ultra Slim 90, when used with diet and exercise, promises to provide great results. It is designed to help lose unwanted and dangerous excess body fat. Lookslim 90 comes in two formulas: original and an “A.M.” formula. The product is taken at night. You stop eating for three hours before bed, and take three capsules right before you go to bed. The all-natural formula of Ultra Slim 90 can be taken in conjunction with prescription medications and other herbal supplements. The active ingredient in Ultra Slim 90 is an all-natural collagen protein that may assist the body in getting rid of excess body fat naturally. For maximum weight loss, the A.M Formula includes an ingredient called conjugated linoleic acid (CLA) that has been shown in clinical trials to aid body fat reduction. Neither the Original formula nor the A.M formulas contain dangerous drugs, like ephedrine, amphetamines, caffeine, herbs or harmful stimulants. Ultra Slim 90 will not cause the jitters or nervousness that is often associated with diet pills. It can also be used by those who are underweight, to encourage stamina and energy. The formula is designed to support the body and fuel its natural mechanisms for processing sugar more efficiently. To see the maximum effect, users are advised to exercise regularly and eat well. The company recommends eating more vegetables, increasing your intake of whole grains, and watching your portion sizes.

Collagen protein, gelatin, magnesium steareate and cellulose.

why isn’t look slim 90 not working for me. it seems to make me more hungry. I try to watch what I eat, but I still have gained 5 pounds. Not happy.

James Grams

I followed the instructions, strictly, for two months, even added 30 mins aerobic exercise and could not lose one pound. I followed a reasonable diet, too. I have tried to get a refund for the two bottles I paid about $120.00 for and cannot get that either! This product did not work for me at all!
