What Are Thermogenics?

For exercisers, dieters, and bodybuilders, fat burning is a top concern. The amount of fat that your body burns each and every day can play a significant role in how quickly you meet your weight loss goals.

Enter thermogenics. A thermogenic supplement works to increase body heat, which can raise metabolism and boost the amount of fat the body burns each day. Thermogenics are most often used by people who need a jumpstart to their weight loss program or have hit a plateau and find it difficult to lose those last few kilos of unwanted body fat.

Fortunately, there are a number of thermogenic products that contain natural ingredients to provide the desired results. The team at Genesis Nutrition Australia recommends that users steer clear of thermogenics made with ephedra and use natural thermogenic supplements instead.

Natural thermogenics may contain safer stimulants like ginger or caffeine to speed up metabolism and aid in weight loss. Thermogenics raise body heat by activating the central nervous system, which will cause both breath and heart rate to increase as a by-product.

How Do They Work?

A thermogenic supplement works through the process of oxidative phosphorylation - a state where the body expends calories at a faster rate to stabilize body temperature. This process increases the baseline metabolism of adipose tissue to deplete fat reserves in the body.

Keep in mind that a thermogenic supplement is not directly related to fat burning; instead, a thermogenic supplement contains stimulant ingredients that will increase metabolism to encourage the body to use fat storages for energy.

To achieve this purpose, a thermogenic product will contain:

  • Stimulants
  • Sympathomimetics

As reviewed above, a stimulant is an ingredient (safe or unsafe) that will activate the nervous system to speed up basic bodily functions. A sympathomimetic is an ingredient that will simulate the sympathetic nervous system to create a fight-or-flight response, as experienced in a time of danger or stress.

A thermogenic supplement can serve two specific purposes:

  1. Improve energy
  2. Lose weight

The use of a thermogenic product will require the body to consume more energy, a.k.a. calories, to keep up with this metabolic demand. As a result, fat loss is imminent, making thermogenics top-selling products for dieters, exercisers, and weightlifters hoping to trim down and lose weight.

Common Ingredients Found in Thermogenic Products:

When using a thermogenic supplement, it’s more important than ever before to read the label carefully. Depending upon where the product is purchased, it could contain a combination of fat burning stimulants, some of which may not be safe or legal in your country of residence.

The good news is that Genesis Nutrition Australia thermogenics contain a variety of natural ingredients that are safe for regular use in the proper dosage. Thermogenic supplements may contain leading ingredients like:

  • Choline: Choline is a B vitamin that helps the body to properly utilize fat and can support long-term weight loss. Choline supplementation will help fat to move quickly through the body so that it is used as energy instead of deposited in arterial walls.
  • Bitter Orange: Bitter orange is an ingredient that contains octopamine and phenylephrine; for this reason, it is used in a number of thermogenic supplements, along with other stimulant ingredients, since it can effectively suppress the appetite. Bitter orange is best used with guarana and green tea to accelerate calorie burning.
  • Green Tea Extract: Green tea contains a compound called EGCG, which has been proven to stimulate fat burning. Contrary to popular belief, the thermogenic benefits provided by green tea are not related to its natural caffeine content, according to researchers.2 Green tea extract can trigger fat burning in adipose tissue due to its high content of both catechin-polyphenols and caffeine.
  • Guarana: Guarana is a popular fat burning ingredient that improves lipid migration to better convert fat into energy. Guarana is also known to suppress the appetite. Guarana can temporarily increase body temperature and metabolism by activating receptor pathways in the body. This process will release and break down body fat storages for quick energy conversion.
  • Hydroxycitric Acid: HCA is a fruit extract from a berry found in the jungles of India. HCA will inhibit the conversion of both starch and sugar into fat to prevent fat production. HCA also affects levels of serotonin in the brain to better regulate the appetite.

Potential benefits of taking Thermogenic products:

The greatest benefit of a thermogenic supplement is seen in its ability to increase metabolism to support quick weight loss through fat burning. In addition, the stimulant ingredients found in a thermogenic product can help to improve energy levels to make it easier to complete daily tasks and activities.

Depending upon the thermogenic product that you use, it may offer its share of unique benefits. For example, a fat burning product that uses green tea extract as a primary ingredient can provide antioxidant protection to the body, along with other related benefits like:

  • Reduced cholesterol levels
  • Rheumatoid arthritis relief
  • Improved immune response
  • Reduced risk of infection
  • Inflammatory bowel disease relief

For many users, a simple thermogenic supplement can greatly improve quality of life by elevating energy and aiding in weight loss. Instead of struggling with an unrealistic diet and rigorous exercise routine, a thermogenic supplement can be effectively used with a balanced diet and exercise plan to support long-term weight loss goals.


Thermogenic Supplements: Timing and Dosage

Since thermogenics contain stimulants, it is incredibly important to follow manufacturer’s directions carefully.

Depending upon your medical history, it may be best to consult with your doctor before taking a thermogenic product to prevent any adverse reactions to stimulant ingredients.

Many manufacturers recommend taking one thermogenic capsule on an empty stomach 15 to 30 minutes before breakfast for the first three days of use. After three days, an additional capsule can be taken 5 to 6 hours later starting on day four. Other products may direct taking one pill with each meal of the day for the best results.

However, some manufacturers require that a thermogenic product is only used for a period of eight weeks followed by a four-week break. It is also important not to exceed the recommended dosage of up to three capsules within a 24-hour period.

Timing and dosage will depend upon the ingredients that a thermogenic product contains. Highly stimulating thermogenics should be monitored carefully and taken per manufacturer’s instructions to prevent any potential side effects.
