Before reading on

I’m not an expert in this field, but I am passionate about nutrition and health.

The articles you’ll find on my site are the result of in-depth research that I’d like to share with you. However, I would like to stress that I am not a health professional and that my advice should in no way replace that of a qualified physician. I’m here to guide you, but it’s important that you consult a professional for specific questions or medical concerns. Your well-being is important. So be sure to consult the appropriate experts and take the best possible care of yourself.

As rates of overweight and obesity increase in Europe, so does the demand for effective slimming capsules. Although it is possible to burn fat and lose weight without these weight loss pills, weight loss pills offer a number of potential benefits over dietary changes or exercise alone. This is because weight loss capsules contain stimulants and other ingredients that can encourage an increase in metabolic rate, among other effects. One should carefully examine the ingredients in weight loss capsules to ensure that the benefits outweigh the side effects and consult a doctor before using these supplements.

Sharon says “Zotrim fits so easily into my busy life and helps me eat less so effectively. I found I was able to eat normally again and because I wasn’t overeating and I didn’t snack between meals, I managed to get rid of my pregnancy pounds and now I’m like the person I was before I got pregnant!”

Glucomannan Complex, konjac in capsule

My opinion

Glucomannan Complex is a dietary supplement rich in dietary fiber and designed to help with weight loss while providing the body with additional health benefits. There are a lot of diet pills on the market, but there are only a handful of products that are actually effective. Glucomannan Complex belongs to the latter category. This supplement is made up of known weight loss agents that have been clinically proven to reduce excess weight.

Glucomannan Complex is designed and manufactured by Evolution Slimming, one of the UK’s leading supplement manufacturers. Its main ingredient is glucomannan, a clinically proven fiber that helps the body lose weight in different ways. Extracted from the root of the konjac tree, glucomannan provides a feeling of fullness by absorbing water and creating a bulky fibrous substance in the stomach. This helps the patient feel full for much longer.


Each Glucomannan Complex capsule contains 500 mg of glucomannan powder, 50 mg of green tea extract, chromium, microcrystalline cellulose, magnesium stearate, silicon dioxide and vegetable gums. Glucomannan Complex is free of artificial flavors, additives and harmful chemicals. Here is its composition:

  • Glucomannan: It is a soluble fiber extracted from the roots of the konjac plant. It is known to promote weight loss, improve digestive health and control blood sugar;
  • Choline: it is a nutrient derived from vitamin B, which helps preserve liver health and boost metabolism;
  • Vitamin B3: important vitamin in the body, it is useful for developing metabolism, reducing cholesterol and contributes to the proper functioning of the nervous system;
  • Chromium: which is an essential trace element for the metabolism of carbohydrates and lipids;
  • Vitamin D3: a vitamin that improves bone health and the immune system.


    • Source of fiber;
    • Helps reduce hunger;
    • Delays digestion;
    • Enriched with vitamins B3 and D3.


    • Not accessible in pharmacies;

Mode of action of slimming capsules

Slimming capsules use various metabolic mechanisms to induce weight loss. Depending on their composition, these medications can address a single or multiple aspects of obesity to induce a reduction in fatty tissue and excess weight. Reducing appetite is one of the mechanisms used by slimming capsules. The ingredients in weight loss capsules can achieve this goal in two ways. They can chemically stimulate the hypothalamus and trick the brain into thinking that satiety has been achieved. Slimming capsules can also act on the stomach by filling it and slowing it down. In both cases, the appetite is suppressed and there is a reduction in the patient’s food consumption, which ultimately leads to weight loss.

Other slimming capsules act on the absorption of nutrients. These compounds use various mechanisms to slow down the absorption of certain nutrients in the intestine. The targeted ingredients include fats and carbohydrates, which are the main nutrients underlying the production of adipose tissue. Instead of entering the bloodstream, they end up in the feces. Consequence: the body receives less and less nutrients and the silhouette becomes slimmer.

Another category of weight loss capsules is that of fat burners. In fact, losing weight involves reducing the volume of adipose tissue already formed. This is where fat burners are very interesting. They force the body to use fat as an energy source instead of carbohydrates which are the body’s preferred energy source. To burn fat effectively, these slimming capsules must be accompanied by more or less intense physical exercises. However, it must be remembered that there is no such thing as a miracle slimming capsule. To be effective, these supplements must be combined with a balanced and moderate diet. The patient should eat quality foods, but in reduced quantities. This diet must also be combined with a physical exercise program in order to burn more fat.

The benefits associated with taking slimming capsules

Although eating foods that contain fiber and protein can help you feel full, weight loss requires calorie restriction. However, weight loss capsules may offer appetite suppressing ingredients that will curb food cravings without involving calorie intake. Stimulants, such as caffeine, can reduce appetite, and research suggests that herbal extracts like hoodia may have appetite suppressant qualities. A study by Van Heerden et al published in the October 2007 issue of the journal Phytochemistry, found that hoodia-containing compounds triggered a small decrease in food intake, suggesting an appetite-suppressing effect.

In addition to helping reduce body weight by burning fat, slimming capsules can reduce the amount of water in the body, which also reduces weight. Compounds that remove water from the body are called diuretics. However, water weight is easy to regain once you drink fluids. Although many supplements focus on promoting fat-burning effects, preventing the development of new fat, a process called lipogenesis, is also important. Many slimming capsules claim to have this effect, but there are few ingredients that have gained scientific support. One ingredient that appears to reduce the likelihood of lipogenesis is betaine. This compound may reduce the activity of genes that promote lipogenesis, according to a study published in the September 2010 issue of the journal Molecular Biology Reports.

Although many slimming capsules can encourage increased energy levels, it is also possible to increase your resting energy expenditure. This means that the patient will burn more calories while resting rather than exercising. This effect is documented by a study carried out by Y. Li et al and published in the June 2010 issue of the International Journal of Obesity. A slimming capsule of multivitamins and minerals may be enough to increase energy expenditure.

Synthetic ingredients

Research has developed a number of molecules that used under medical supervision can help significantly lose weight. It should be noted, however, that these are rather sensitive medications and that their use for self-medication should absolutely be avoided.


Orlistat, reduces the absorption of intestinal fats by inhibiting pancreatic lipase. Some side effects of using orlistat include frequent, oily stools (steatorrhea). if fat is reduced in the diet, symptoms improve. Initially available only by prescription, it was approved for sale over the counter. Of the 40 million orlistat users worldwide, only 13 cases of severe liver damage have been reported.


Lorcaserin has been approved to combat obesity and other co-morbidities. Participants’ average weight loss during the study phases was modest, but the drug’s most common side effects were considered mild. This molecule reduces appetite by activating a serotonin receptor known as the 5-HT2C receptor in a region of the brain called the hypothalamus, which is known to control appetite.

Sibutramine is an appetite suppressant or appetite suppressant, which reduces the desire to eat. Sibutramine can increase blood pressure and cause dry mouth, constipation, headaches and insomnia. Sibutramine has been withdrawn from the market in the United States, United Kingdom, Europe, Australia, Canada, Hong Kong and Colombia. Its risks (myocardial infarction and stroke) outweighed the benefits.


Rimonabant was an anti-obesity appetite suppressant that was approved in Europe in 2006 but was withdrawn worldwide in 2008 due to serious psychiatric side effects. It was never approved in the United States. Rimonabant is an inverse agonist of the cannabinoid CB1 receptor and was the first drug approved in this class.


Pyruvate is a chemical produced by the body during the production of glucose. It is also found in some weight loss capsules, generally in the form of calcium pyruvate. Pyruvate could increase fat burning potential as well as metabolism, which could theoretically help with weight loss. Although pyruvate appears to help promote small amounts of weight loss, current research is limited. And like many ingredients found in diet pills, more research is needed to evaluate weight loss claims.

Natural ingredients

Many plants contain compounds that can help curb appetite and boost fat burning. These ingredients are generally healthier than their synthetic counterparts because the associated side effects are generally fewer.


Many diet pills contain caffeine as an active ingredient. These can be coffee or caffeine extracts from plants such as guarana, yerba mate or kola. As a stimulant, caffeine increases metabolism, but usually not enough to create significant weight loss. Caffeinated herbs may aid weight loss by delaying gastric emptying, meaning they keep the stomach full longer, according to a 2001 study published in the Journal of Human Nutrition and Dietetics. However, diet pills containing caffeine cause adverse effects, such as nervousness, or serious ones, such as brain swelling.

Green tea

Green tea is also a source of caffeine, but it’s not the only active ingredient believed to help with weight loss. Tea also contains catechins, which are phytochemicals that can increase metabolism. However, while green tea is a source of nutrients that help burn calories, it doesn’t help with losing much weight, according to a study published in 2012.

Green coffee

Green coffee, which is unroasted coffee, is also a source of caffeine. It also contains high amounts of chlorogenic acid, a compound that has been shown to prevent fat accumulation in mice and humans, according to the Office of Dietary Supplements. Although it appears that green coffee bean extract shows promise for weight loss, very few studies exist on the subject. To better evaluate how green coffee bean extract might help with weight loss, additional clinical research is needed.

White bean

White beans are legumes native to Central and South America that prevent the breakdown and absorption of carbohydrates, while suppressing the appetite. In slimming capsules, the legume appears under the name Phaseolus vulgaris. When taken as part of a low-calorie diet, these seeds can help you lose up to 6 pounds over a 12-week period, according to a study published in 2014 in the journal Obesity. However, a 2011 study published in the British Journal of Nutrition says much of the research on white beans and weight loss is flawed, and recommends larger, more rigorous studies to understand how it works.

Conjugated linoleic acid

Conjugated linoleic acid, or CLA, is made from linoleic acid. It is found naturally in foods of animal origin such as milk and beef. Scientists theorize that CLA helps promote weight loss by destroying fat cells. Supplementing with CLA appears to help promote weight loss in obese people, according to a 2012 study published in Nutrition. However, the researchers note that while the study subjects lost weight, the loss was modest. This suggests that CLA alone is not a silver bullet for significant weight loss. Additionally, a study on CLA and weight loss reports mixed results. The study authors also expressed concerns that the substance could increase triglycerides and bad cholesterol, while lowering good cholesterol levels.

Hoodia gordonii

Hoodia gordonii, also known as ‘Bushman’s Hat’, is a leafless, thorny succulent plant that grows naturally in Botswana, South Africa and Namibia. The plant is sought after as a slimming capsule for the treatment of obesity. A small clinical study, conducted at the University of Michigan, found that hoodia latex can significantly reduce food intake in test subjects due to the herb’s ability to suppress hunger in humans. Hoodia gordonii, as a slimming capsule, contains a molecule that is much more effective than glucose in treating health problems related to blood sugar, including food cravings and fluctuations in blood sugar levels.

The vitamins and minerals contained in slimming capsules

Apart from chemical compounds and plant extracts, slimming capsules also contain minerals and vitamins which contribute to weight loss.

Vitamins that make you lose weight

In the context of weight management, vitamin B6 is extremely important because it helps convert food into usable energy. Also known as pyridoxine, this nutrient supports muscle growth by increasing the number of protein building blocks (amino acids) that are used for protein synthesis. More muscle means a higher metabolism, an important aspect of weight loss. Not only does vitamin B6 increase energy expenditure and metabolism, it also improves blood flow by helping with hemoglobin synthesis. It also helps balance blood sugar levels, which in turn reduces sugar cravings and the likelihood of overeating. It is therefore an essential nutrient for weight management.

Vitamin B12 helps convert carbohydrates into glucose. The same goes for fatty acids. It therefore provides a great advantage for those who want to lose weight. In addition to this, vitamin B12 also increases the body’s ability to absorb and digest food, which helps with digestion, protein synthesis and nutrient assimilation.

Minerals for weight loss

Microelements and trace elements help regulate metabolism and many cellular reactions. They are also necessary for the body’s production of energy called adenosine triphosphate (ATP).

Chromium is a trace element necessary for carbohydrate metabolism. It enhances the effect of insulin, maintaining, balancing and optimizing energy levels. For this reason, it has been called glucose tolerance factor (GTF chromium) since the 1950s. This mineral stimulates protein synthesis and reduces fat levels in the body. It also increases satiety and reduces hunger and cravings. Anyone who wants to improve their physique needs enough chromium in their diet to achieve their goals.

Zinc is an element that has been shown to improve the immune system, heal wounds and maintain taste and smell. Plenty of zinc in the diet can help improve weight loss for people who are overweight or obese. A 2013 study published in “Biological Trace Element Research” reports that obese individuals tend to have low levels of zinc. Therefore, consuming more zinc can benefit overweight and obese people. Another study published in 2013 in “Advanced Pharmaceutical Bulletin” showed that obese subjects, who consumed zinc supplements, lost weight and had improvements in their triglyceride levels.
