How do appetite suppressants work?

Sympathomimetics (the so-called chemical appetite suppressants) block the hunger center in the diencephalon; are appetite suppressants natural?

Natural supplements that act as appetite suppressants stimulate the sympathetic part of the nervous system, causing an “inhibition” of the hunger center and thus reducing appetite.

Increased performance, euphoria, and high energy consumption are other effects of appetite suppressants, among others.

Although they are safe up to certain doses or in certain circumstances, you should pay attention to the labels and advice and avoid dubious sources.

But let us leave the technical matters aside and look at your problem… appetite, hunger, or whatever you call it… cravings… if you are overweight and cannot stick to any kind of diet, including a hybrid or balanced one, you will NEVER succeed.

Appetite takes hold of you and breaks you down after a few days, leaving behind hopes of regaining the figure, a flat stomach, and a muscular physique that you only dream of. Remember, dreams are dreams, so you must face reality.

Fighting appetite is like fighting a toothache. It is a sensation that constantly occupies the mind and can overcome even the strongest motivations, and this is where appetite suppressants could help.

First, recognize the problem

Wanting to eat and having an appetite are two different signals.

• Appetite arises when the body does not have enough energy, but also when the stomach is completely empty. The food from the last meal has been processed and sent to the intestines, where much of it will be absorbed by the body.
• The need to eat can occur at any time, sometimes even right after a meal. In this case, your body is sending you the wrong signals, making you eat when you do not need to. This is largely due to hormonal imbalances caused by various factors, including psychological ones.

So, before considering appetite suppressants, analyze your problem on your own or with a professional and try to identify what is happening and how to solve it.

Second, understand things

With excess weight:

• Abdominal fat acts as an organ that alters hormonal balance and triggers inappropriate changes in insulin, ghrelin, and leptin (hormones that regulate appetite).
• The higher your body fat percentage, the harder it will be to distinguish between appetite and cravings, so work on this mainly by training hard while following a diet that is not too restricted in calories.

On a high-carbohydrate diet:

• Carbohydrates are metabolized by the body under the action of insulin, the hormone responsible for storing sugars and proteins.
• When you eat too many carbohydrates or sugary foods, your insulin levels spike and keep you hungry; it is often said that sugar requires sugar, and that is absolutely true.
• The more carbohydrates you consume, the more you stimulate your appetite; moreover, you need to be careful because this also applies to complex carbohydrates, which are known to reduce appetite and increase satiety. They also stimulate insulin to a lesser extent, but inevitably too much will be stored as fat, which in turn disrupts the hormones that regulate appetite.

When you eat lots of snacks:

• It is your worst enemy; eating snacks (not protein snacks) between meals prevents your body from using nutrients properly and keeps you hungry for food.
• You are not really hungry, but frequently eating small amounts of food such as sweets or even lots of nuts keeps you wanting to eat and triggers cravings again, because leptin and ghrelin can no longer perform their regulatory functions.

Appetite suppressants: where do they come into play?

It is vitally important to discipline yourself not to eat between meals and to avoid consuming too many carbohydrates, especially sugars, which are rapidly absorbed.

In addition, it is important to know that during a diet we all have to go through a period of adjustment, or abstinence, during which we are not really hungry but simply want to eat something more.

If you manage to get through this milestone, which lasts about 10 days, it will be very easy to continue your diet without setbacks or inconveniences; but if you cannot, appetite suppressants can help you avoid feeling hungry.

They will be a great help in maintaining your weight-loss or definition diet over the long term.

Let’s remember that hunger is the desire to eat, which may be physiological or may be driven by external factors ranging from stress and mood to frustration.

This is where things start to get complicated, because the feeling of hunger arises in response to physiological needs.

Basically, the body needs fuel; it needs an intake of nutrients to ensure proper functioning. However, this physiological hunger can be difficult to recognize and may be confused with emotional hunger.

In fact, many effective weight-loss supplements help combat the harmful effects of emotional eating, but do they work on satiety?

A feeling of satiety could be defined as a state of not feeling hungry, whether physiological or emotional. In other words, a product can stimulate satiety with a powerful appetite-suppressing effect.

However, you should bear in mind that there are also other ways to reduce appetite naturally, whether through food or exercise, using signals that act on the secretion of serotonin, a hormone that plays a role, among other things, in regulating appetite.

Appetite suppressants: are they reliable?

As mentioned above, it is perfectly possible to reduce appetite; however, this does not always happen naturally!

Many people still use synthetic drugs to achieve satiety.

But nowadays, the industry, using herbal technology, has turned to plants with appetite-suppressing effects, which have been used for thousands of years all over the world.

Natural appetite suppressants have also attracted interest in the scientific community as a way to prevent the complications of overeating. Consequently, positive effects have been observed at many levels of the body: the liver, the cardiovascular system, etc.

Although older formulas inspired the development of certain slimming food supplements, scientists have also taken their research further. As a result, they identified and isolated natural active compounds with appetite-suppressing effects.

Several of them are now available as nutritional supplements; however, you must follow the recommended doses and maintain daily physical activity. In short, the reliability of any appetite suppressant is established if:

• They have a clear list of ingredients;
• You understand everything on the label;
• They give you a slight boost during training;
• They do not cause insomnia or stomach discomfort;
• Of course, you notice that you have less appetite.

Above all, these natural formulas, which come in complex matrices, will help you reduce your intake of fats and carbohydrates by directly or indirectly inhibiting fat synthesis and the accumulation of body fat.

The fact is that appetite suppressant supplements act on the brain and hormones, as well as on certain enzymes, to perform their function. Obviously, it would be ideal to add some foods that support the process, right?

Appetite suppressants: how do they work?

In various ways, appetite suppressants (natural ones) can increase serotonin, dopamine, and noradrenaline levels in the brain.

• These neurotransmitters transport, enhance, or transmit signals throughout the cells in your body.
• By increasing the levels of these neurotransmitters, signals are sent to the hormones, reducing appetite and helping you feel satisfied for longer.

In other words, they work by tricking your brain into believing that you are not hungry and that your stomach is full.

Most do this by increasing levels of the hormone serotonin to “feel good”; it is responsible for regulating mood, appetite, and sleep patterns, among other things.

There are also solutions that fill the stomach by forming a gel that slows digestion, and others that block hunger through the adrenal gland, inhibiting the brain from sending appetite signals to the body.

Many products, however, add ingredients that help reduce appetite while doing other things, such as increasing energy or performance, eliminating excess fat, and counteracting the effects of training-related fatigue or even stimulating the nervous system.

But, to measure the effects of the best appetite suppressants, we will discuss each of them, to name a few:

• Caffeine
• Conjugated linoleic acid – CLA
• Psyllium
• Glucomannan
• In addition to herbs such as: Garcinia cambogia, Griffonia simplicifolia, Caralluma fimbriata, Cyamopsis tetragonolobus or Ceratonia siliqua, Amorphophallus konjac, or Citrus aurantium.

Among other ingredients that continue to be used and other formulas being developed day by day in the weight-loss and slimming supplement industry.

Appetite suppressants: let's talk about protein

Protein itself regulates appetite by optimizing the action of leptin, an appetite-suppressing hormone, and reducing the secretion of ghrelin, which increases appetite.

Casein is the gold standard for weight loss and appetite regulation. Derived from milk, micellar casein forms a gel in the stomach that slows gastric emptying while also maintaining a positive nitrogen balance that is more sustainable over time.

This process increases metabolism, burns more calories, and reduces appetite for a long time, making it great for everyone—not just athletes and bodybuilders eager to use protein powders.

Appetite suppressants: caffeine, really?

Caffeine is an alkaloid from the methylxanthine family that stimulates the central nervous system. Naturally present in coffee and green tea, it affects appetite hormones, reduces the sensation of hunger, and activates metabolism.

Additionally, coffee is rich in chlorogenic acids and PYY protein, just like green tea; these acids control and suppress appetite, while PYY protein, released in the large intestine, literally eliminates the need to eat [1].

Appetite suppressants: CLA, too?

Conjugated linoleic acid CLA is a natural product that acts by burning fat, preventing its formation, and blocking calorie storage, thereby reducing weight gain, especially weight regain.

But CLA is also one of the effective appetite suppressants, because it increases the feeling of fullness. In a study that included all variants, in just 13 weeks of intervention, CLA significantly increased the feeling of fullness and satiety [2].

Appetite suppressants: apple, how?

The thing is, these fruits contain plant fibers; in apples, these are pectins that, in the form of extracts, apple cider vinegar, or as an isolated supplement, absorb water and form a viscous gel in the stomach.

In this way, the pectins found in some appetite suppressants will slow gastric emptying and induce a feeling of fullness.

This appetite-suppressing action is ideal for satisfying the small pangs of hunger that may occur at the end of a meal, for example.

Appetite suppressants: psyllium fiber, more gel?

It is ultimately a soluble, gel-forming, non-fermented fiber supplement that may help consumers stay fuller for longer and support their weight-loss diets.

Although the mechanisms involved in controlling body weight are very complex and involve many more variables than satiety alone, psyllium husk may be a viable option for you, as it has demonstrated its effectiveness in more than one study showing that it can gel in the stomach, an important aspect in real life [3].

Appetite suppressants: glucomannan

Derived from the root of the konjac yam, glucomannan is a water-soluble fiber that swells with water in the stomach, providing an accelerated feeling of fullness and noticeably reducing appetite.

On the other hand, it slows gastric emptying, reducing cravings and the urge to snack—the ones you may sometimes experience while following a weight-loss or cutting diet.

It absorbs so much liquid that a small amount of glucomannan added to a glass of water turns the entire contents into a gel, and according to a study published in several health journals, it provides an essential benefit: in addition to delaying stomach emptying to increase satiety, it may protect against fat gain [4].

Appetite suppressants: what about natural herbs?

Garcinia cambogia is a fruit that contains the active ingredient hydroxycitric acid, HCA, which burns stored fat but also affects appetite. By increasing serotonin levels, which reduce hunger and sugar cravings, it also reduces fat accumulation in adipocytes [5].

On the other hand, Griffonia simplicifolia is one of the best sources of 5-hydroxytryptophan (5-HTP) and one of the recognized appetite suppressants; a compound that is converted into serotonin in the brain. Serotonin tells the brain to reduce food intake and sugar cravings [6].

Here is a well-kept secret: native to India, Caralluma fimbriata is a plant used for many years by local tribes to increase endurance and suppress hunger. It has a natural appetite-suppressing effect and helps support the body's physical performance [7].

Like carob, Cyamopsis tetragonolobus provides an appetite-suppressing gum; this is the famous guar gum. Obtained from the seeds of Cyamopsis tetragonolobus, it has a high content of galactomannans that swell in the stomach, delaying gastric emptying and increasing the feeling of satiety [8].

Likewise, Magnolia officinalis has benefits against impulsive snacking because it does not stimulate the feeling of satiety, but it helps combat stress, a factor known to increase emotional eating, the risk of overeating, and the cravings experienced by overweight people [9].

Finally, behind the scientific name Citrus aurantium lies bitter orange. Due to its p-synephrine content, it promotes fat elimination or increases energy expenditure and lipolysis, but it can also act as one of the best appetite suppressants in the world [10].

Conclusions

Although appetite-inhibiting supplements are popular, many of these products have been found not to work well.

Some supplements on the market also contain synthetic ingredients, which can sometimes cause side effects.

That is why we implemented a strict procedure to provide you with an extensive reference list, including multifunctional supplements recognized as reliable and safe.

To complement these goals, remember to eat well, drink plenty of fluids (preferably water), sleep well, and exercise.

In every respect, you should try to activate the AMPK pathway to lose fat and choose some fat-loss supplements, as shown in a video prepared by MASMusculo several years ago.
