1. Spirulina, the versatile cyanobacterium for weight loss

spirulina to lose weight

Spirulina is incredibly beneficial for the human body. It has gained widespread international fame because of its richness in nutrients and immense benefits. For those who do not yet know it, spirulina is actually a cyanobacterium that thrives in healthy lake waters at high altitudes.

This cyanobacterium is commonly used as a food supplement for its many properties. But also to replace the proteins of red meat and eggs for vegans and vegetarians. However, in recent times it has also gained a good reputation as an ideal supplement to aid in slimming. It can therefore help you lose weight if you consume it correctly.

How does spirulina work on weight loss?

Due to the high fat content of red meat, people tend to turn to a diet lower in animal protein to induce weight loss. However, this drastic step often results in a severe lack of amino acids in the body. However, the latter are essential for the regeneration and growth of cells.

Therefore, spirulina is a great substitute. It contains 60 to 70% protein (1). And because metabolism takes energy, protein also helps maintain healthy fat burning. Also, according to several studies, spirulina also helps reduce appetite in overweight and obese people.

Spirulina can therefore promote better protein intake, reduction of appetite (and thus allow optimal meal management) and better shape. It is highly effective when combined with regular physical activity and a healthy diet (2).

Benefits and health benefits of spirulina

Besides its slimming effect, spirulina can help treat anemia and prevent it, thanks to its high iron content. Of course, it contains many other minerals and vitamins, which will help you keep in shape. On the other hand, spirulina is a natural anti-inflammatory (3). If playing sports causes inflammation (or if you suffer from it for other reasons), incorporate spirulina into your eating habits.

People looking to lose weight may find it difficult to regulate their blood cholesterol and triglyceride levels. If this is your case, and again, spirulina can help you remedy this. Indeed, this cyanobacterium is ideal for fighting bad cholesterol and reducing the body’s triglyceride levels (4).

Spirulina can help you better regulate your blood pressure, thanks to its hypotensive effects. Finally, with a composition highly concentrated in natural antioxidants, it is ideal for preventing the development of cardiovascular diseases and various types of cancer. If it’s at the top of this list of the best natural dietary supplements for weight loss, it is clearly no accident.

Dosage: recommended dosage of spirulina

The recommended dosages of spirulina vary from 1 to 6 g per day. However, its effects are felt even at low doses. Also, in order to maximize its benefits, try eating spirulina in the morning or during the day, rather than at night. Follow the recommendations and dosages on the packaging of your spirulina tablets to adapt your daily intake.

Side effects and contraindications

It is important to ensure that the spirulina you consume is of good quality and pure. With a good quality spirulina, not contaminated with chemicals, you do not risk anything. However, contaminated spirulina can cause the following side effects, including abdominal pain, liver damage, vomiting and nausea, as well as feeling thirsty. For these reasons, it is important to choose a quality spirulina.

2. Chlorella, the purifying benefactor algae


Chlorella is one of the most widely used supplements in Japan. Like spirulina, chlorella is a freshwater algae with a multitude of benefits for the body. It is also one of the oldest species on the planet. This algae has the unique ability to reproduce up to eight times a day, making it a sustainable source of nutrients.

How Does Chlorella Work on Weight Loss?

As we’ve said before, losing weight can be difficult at times, especially with age. However, with regard to chlorella, clinical studies are very promising. This seaweed is among the best natural food supplements for weight loss due to its notorious effects on several key metabolic mechanisms.

Chlorella acts by several mechanisms. It has regulatory effects on hormones, and thus promotes the general hormonal balance of the body. Thanks to its antioxidant properties, it promotes the elimination of waste from the body (toxins, free radicals, etc.). An organism free from these harmful molecules functions optimally. The metabolism is thus stimulated. And the more it is stimulated, the more fat it burns.

And that’s not all, chlorella, by surrounding toxins and heavy metals residing in the body, facilitates their elimination and also prevents their reabsorption. This is because of its considerable detoxifying properties (5). Finally, this algae, which is both beneficial and purifying, also stands out thanks to its composition. This is particularly rich in mineral salts, vitamins and essential fatty acids (6) (7). It will make a perfect dietary supplement for weight loss, but also for maintaining high energy levels in the body!

The other health benefits and virtues of chlorella

Apart from its slimming effect, chlorella helps lower blood sugar levels, as well as fight bad cholesterol. This algae helps strengthen our immune system (8) and purify the body. Thanks to its exceptionally rich composition, chlorella is currently being studied in the context of cancer prevention. It is also an effective dietary supplement for ulcerative colitis, fibromyalgia and hypertension.

Recommended dosage of chlorella

The dosage depends above all on your needs, your age, your height and your state of health. However, the average remains one to three 500 mg tablets with a glass of water three times a day.

Side effects and contraindications

The majority of side effects are symptoms of any detoxification program (the symptoms of the healing crisis). They are therefore fatigue, headaches, cramps, nausea, diarrhea and insomnia. However, people who are allergic to iodine or are taking medication should consult a doctor before using chlorella. This algae is not recommended for people sensitive to mold and children. For everyone else, chlorella is a safe substance.

3. Garcinia Cambogia, one of the best natural food supplements for weight loss

Garcinia Cambogia weight loss supplement

Garcinia Cambogia capsules represent one of the most famous natural food supplements for weight loss. They are made from an extract of the peel of the fruit, which indeed contains high amounts of hydroxycitric acid (HCA) (9). The latter has demonstrated its ability to lose weight according to numerous studies.

How does garcinia cambogia work on weight loss?

Studies have indeed shown that garcinia cambogia can promote weight loss in two different ways. The first is to suppress appetite and fight cravings by inhibiting the absorption of serotonin in the brain. High levels of serotonin in the body may reduce your appetite, especially the appetite for sweet (10).

On the other hand, as one of the best natural weight loss supplements, garcinia cambogia is also a powerful anti-inflammatory herb. It will therefore help you fight against muscle or joint pain (associated with playing sports). And since it is a natural concentrate of antioxidants, this plant will allow you to fight against oxidative stress and boost your metabolism (12).

Recommended dosage

The recommended doses may vary, but, as a general rule, it is recommended that you take 500 mg of garcinia cambogia three times a day, 30 to 60 minutes before meals. Against bulimia and its attacks, the dosage to be respected is 1000 and 1800 mg of fruit per day.

Side effects and contraindications

Most of the studies done have concluded that garcinia is safe for healthy people, in the recommended doses. However, due to lack of studies, it is best not to take garcinia during pregnancy and while breastfeeding. In addition, this plant is not recommended for people undergoing treatment for cholesterol, diabetes or dementia.

Normal consumption of garcinia cambogia does not cause side effects. On the other hand, in high doses, this plant can cause gastrointestinal disturbances. These disorders can be diarrhea or gas. Observe the dosages to avoid them!

4. Green tea, a powerful antioxidant with recognized slimming properties

green tea to lose weight

Green tea extract is a popular ingredient, used as a base in many supplements to aid in weight loss. In fact, several studies show that epigallocatechin gallate (ECGC, the main antioxidant in green tea) promotes fat burning.

How it works ?

Epigallocatechin gallate (ECGC) is the major antioxidant in green tea, although it contains many others. It works to promote fat burning in the body (13). Besides the effect of ECGC, green tea extract works by increasing the activity of norepinephrine in the body. It is a hormone that helps burn fat and thus promotes weight loss. In fact, watching horror movies has been shown to help burn calories, this being an effect of adrenaline, a derivative of norepinephrine!

Physical activity is essential for weight loss. Green tea, thanks to its stimulating effects on the body, contributes to the improvement of physical performance. Better physical condition promotes weight loss and a better balance between fat and muscle mass.

Benefits and health benefits of green tea

All of the health benefits of green tea should apply to green tea extract. This therefore includes improving general health and fitness. The presence of caffeine in green tea extract helps fight fatigue and regain greater vitality.

Green tea capsules can be taken with or without food.

Finally, remember not to exceed three to five cups of green tea per day, or to follow the dosage indicated on your product if you consume green tea in the form of herbal tea.

Side effects and contraindications

Green tea extract is generally well tolerated, except for people with sensitivity to caffeine. However, it should be avoided by young children and adolescents, due to the presence of caffeine in its composition. In addition, it should be noted that caffeine has addictive power. It is therefore necessary to respect periods of pause so as not to become dependent (e) on this molecule.

Guarana is best known for its fruit the size of a coffee bean. As a food supplement, it is above all a natural stimulant. In fact, a bean of guarana contains up to ten times the amount of caffeine than a coffee bean. In other words, its stimulating capacities are increased tenfold!

How does guarana work?

Studies on guarana have concluded that it does have a thermogenic effect on the body. This means that the guarana acts as a real fat burner (14). If it is among the best natural food supplements for weight loss, it is above all for its ability to increase caloric expenditure during exertion and at rest. As such, guarana speeds up the basal metabolism, thereby increasing body heat and fat burning.

On the other hand, guarana has another interest in weight loss. This fruit transformed into a food supplement promotes the feeling of satiety, which allows you to better control your hunger, and your weight (15)! Guarana (and more precisely the caffeine it contains) thus helps reduce appetite, better manage the contents of your plate, and facilitate weight loss.

In addition, the caffeine in guarana also increases urine secretion which obviously results in less water retention. This is because caffeine is a diuretic and an alkaloid, which means that it is metabolized in the liver and excreted by the kidney.

Health benefits and virtues of guarana

Guarana has other benefits that should not be overlooked. Indeed, this fruit or food supplement helps fight fatigue and drowsiness. As a reminder, it can contain up to ten times more caffeine than coffee beans. This fruit is therefore ideal for combating fatigue and its effects on concentration.

Indeed, it can be harmful in large doses or over a long period. Ultimately, how safe it is most often depends on how much we consume and use it.

Some potential side effects may occur, such as nervousness, heart palpitations, insomnia, or heart irritation from the caffeine. This is why it is essential to stick to the recommended doses and not to combine guarana with other sources of caffeine.

6. Konjac, the last slimming secret

Konjac supplement to lose weight

Konjac is often cited among the best natural food supplements for weight loss. Thanks to its richness in soluble fibers, Konjac promotes weight loss through several mechanisms. First, it absorbs up to 100 times its own weight in water. It therefore acts as a real natural appetite suppressant (16). By taking up space in the stomach, it helps strengthen the feeling of fullness after meals, or when you are feeling hungry. You should also be aware that Konjac delays stomach emptying. In addition to strengthening the feeling of satiety, it prolongs it over time!

In addition, this food is very low in calories. It therefore allows you to fill up with nutrients, without increasing your calorie intake. Finally, and like other soluble fibers, it delays the absorption of fat. However, glucomannan is different from other soluble fibers because it is more viscous, which makes it even more effective.

Health benefits and virtues of konjac

According to several studies, glucomannan can lower cholesterol as a whole, and in particular LDL, which is the bad cholesterol. Konjac also acts on the blood triglyceride level and helps to lower it.

The blood sugar level in those at risk can be reduced by consuming konjac in the form of regular cures. Finally, this herb is also found to be very effective in restoring and regulating bowel function (17).

Recommended dosage

Side effects and contraindications

According to research, green coffee extract seems to have a very interesting protective role for the body. However, like all products, moderation remains the rule of thumb.
