Appetite Suppressants – how do they work

appetite suppressants diet pillsAppetite suppressants can be very effective for reducing the daily intake of calories. In fact one of the most sought after weight loss drugs in the world is an appetite suppressant. It’s called Phentermine, but here in the UK it is only available via a GP and most people will be unable to attain a Phentermine prescription because the drug has such an addictive nature doctors only use it to treat the dangerously obese.

However, the fact that the go-to-drug doctors use in such cases is an appetite suppressant speaks volumes for the benefits appetite suppression can provide, and Phentermine is not by any means the only appetite suppressant that works. Many hunger controlling supplements can be just as effective and are not subject to the same restrictions.

The Greed for Food

People eat for two reasons:

  • A biological need for nourishment
  • The desire to do so

The calories and nutrients in food are the body’s fuel. The calories provide the body with the energy it needs to power normal function and the nutrients are used for cellular repair and other important biological needs. When it comes to weight loss and weight gain though, it’s all about the calories. The average person only requires 2000 – 2500 calories per day and this should be sufficient to maintain the present weight. However, when the body is provided with too many calories it converts them to fat. Conversely, in situations where the body is deprived of calories, either through deliberate restrictions (dieting) or circumstances that result in food being unavailable, the body takes advantage of its stores of fat and burns them for energy. It is normal for feeling of hunger to kick-in before such a situation arises because hunger is the body’s way of saying it’s time to top-up the tank and provide some more fuel.

Unfortunately people also eat for another reason, other than the desire for food, and in many cases this could best be described as greed.

When someone has just eaten a meal and their mind turns to thoughts of puddings etc., it is not a biological need that feeds these thoughts, but rather the desire for something that is unusually sweet or tasty. In-between-meal snacking can also usually be attributed to desire rather than need. Eating pudding and treating yourself to snacks can quickly become a habit and habits can be very hard to break. Eating food can also provide a feel-good factor that is often taken advantage of by those who “comfort eat”.

Breaking Bad Habits

The habit of overeating can be extremely hard to break. When people have allowed their eating habits get out of control the body adapts to all that “over-stuffing”, the stomach stretches to create space for more food, excessive eating becomes easier, and the habit becomes harder to break. Of course, not everyone allows things to go so far, but obesity is on the rise and the associated health risks place a huge financial burden on the NHS.

People usually decide to try and break their bad eating habits for one of three reasons:

  1. They take a look in the mirror and don’t like what they see
  2. They begin to fear for their health
  3. Their GP instructs them to do so

Unfortunately the desire to lose weight is often dwarfed by the desire for food; so many people need some extra help. That’s where appetite suppressants come in.

How Appetite Suppressants Work

Some appetite suppressants work on a mental level by removing the desire for food; others provide a feeling of fullness that makes it hard or uncomfortable to continue stuffing the stomach with food.

The prescription drug Phentermine is a good example of an appetite suppressant that works on a mental level. When the active ingredients have been absorbed into the body they trigger the release of the hormone norepinephrine, which then puts the body into a state of flight or fight. This is an age-old survival mode that dates back to the times of early man. Food was not always available and early man’s existence was constantly under threat from predators. Feelings of hunger could be a fatal distraction in a life or death situation, so the body adapted by secreting hormones capable of quelling the hunger pangs. Phentermine can trick the body into making the necessary secretions when no danger is present and a number of diet supplements are designed to work in the same way.

Konjac is also a powerful appetite suppressant and is one of a number of ingredients that work by providing a feeling of satiety. It is a fibrous ingredient taken from the roots of a plant. It is low in calories and provides very little in the way of nutritional value but it is extremely absorbent and soaks up liquid like a sponge. Appetite suppressing diet supplements that contain Konjac are generally consumed half-an-hour before meals and are taken with plenty of water. This causes the fibres to swell inside the stomach, reducing the space available for food and creating a feeling of satiety that signals the brain the stomach is full.

In Conclusion

People put on weight because they consume too many calories. Good appetite suppressants that work in the intended manner can provide dieters with the extra help they need to control their desire for food, lower their calorie intake, and make the changes that are necessary for them to reach their weight loss goals. They also offer a benefit that fat burners and other types of supplements do not. Good habits are as easy to acquire as bad ones, so after a period of time eating less can become a habit as well. It is a habit that can help ensure the weight stays off and may further explain why one of the weight loss drugs favoured by doctors is an appetite suppressant.
