Thermogenics (fat burners), is the name given to a group of compounds that have the effect of speeding up metabolism.

Thermogenesis, as the name suggests, means the production of heat within the body ['thermo': heat, 'genesis': the beginning]. Heat is a by-product of energy production. Therefore, if more fuel is burnt up by the body, more heat is generated.

Some examples of thermogenics include certain foods, herbal extracts and fruit extracts. For example, capsaicin from chillis; caffeine from coffee, tea or guarana; and oxedrine from citrus aurantium.

The most powerful fat burners are supplements that contain combinations of various thermogenic ingredients in concentrated forms.

Fat burners are often used by people wanting to lose weight. They help to create an energy deficit by increasing the body’s overall energy expenditure.

Each day the human body burns energy. The total energy expended comes from three areas: the basal metabolic rate, any exercise performed and the energy used by the body in digesting food. If a fat burner is used it increases the energy expended in the basal metabolic rate and during exercise.

For example, during a day a person may burn 1500 calories (6300 kilojoules). 70% of those calories may come from their basal metabolic rate (1050 calories), 20% may come from their daily exercise (300 calories) and 10% from digestion (150 calories).

If they then take a fat burner, particularly one that contains several powerful ingredients, their daily calorie expenditure may increase to 1800 calories. Of those calories, 71.33% may come from their basal metabolic rate (1284 calories), 20.34% may come from their daily exercise (366 calories) and 8.33% from digestion (150 calories).

By increasing the calorie expenditure each day it becomes much easier to create a calorie deficit and therefore lose weight. So if our person in the example above, consumes 1500 calories from food during the day, without a thermogenic their body fat and weight will remain the same (calories in equals calories out).

However, if they eat (and drink) the same amount of food but also take a fat burner, then they will have a calorie deficit that will need to come from their body’s energy stores, resulting in a loss of body fat and weight.

It is important to note that if their food intake is not controlled or they don’t perform any exercise, then it is highly likely that using a fat burner would not be of benefit in helping them lose body fat or weight; they are not ‘magic pills’. You can’t expect to take a couple of capsules, then go home and eat pizza and drink alcohol and expect to get results.

Thermogenics only work when their use is combined with a good nutrition and exercise program. They simply help you achieve your weight loss goal faster.

Thermogenics are also used by people who simply want an energy boost. If you feel tired during the day or if you want a ‘pick-me-up’ before your exercise session, then thermogenics can certainly help. Thermogenic ingredients stimulate the nervous system helping to boost your energy and increase alertness.

For best results thermogenics should be taken twice a day on an empty stomach at least 30 minutes prior to meals or before exercise and should not be taken after 4:00pm as they may interfere with sleep. Also, it is best to ‘cycle’ their use. This means use them continuously for a maximum of eight weeks and then have at least two weeks off. This prevents the body from becoming desensitised to the ingredients.

There are several very effective thermogenic supplements on the market that can accelerate progress towards your goal. Those containing guarana and green tea extracts along with other powerful herbal extracts like coleus forskohlii and evodiamine are the most effective. They boost your metabolism and promote the use of fat for fuel in your body. It is also best to choose thermogenic supplements in capsule form rather than pill form because the ingredients are more readily absorbed.

They may be used by most people but because they have a powerful effect on metabolism they are not for everyone. In particular, people with high blood pressure or who have heart problems should avoid their use. Also people under the age of 18 or over 65 should avoid them also.

Furthermore, if you are considering using thermogenics, it is essential to see your doctor first and obtain their approval.

If you have tried getting into shape in the past but haven’t got the results and if you are willing to make some changes to your nutrition and exercise habits then thermogenics will certainly help.

Due to the popularity of recent findings, green tea has almost become synonymous with weight loss and diet. The addition of green tea diet into diet pills and weight loss supplements is perhaps spurred by reports of harmful side-effects of other drugs like ephedra.
Why Choose the Green Tea Diet?
For four thousand years, green tea has been used all throughout Asia as a beneficial health and medicinal drink. It is different from all other tea diets because its liquid is extracted by steaming the leaves of the Camellia sinensis plant as opposed to full oxidation. In this way, the green tea diet manages to preserve a lot more antioxidants and keep them intact for the body to use.
The green tea diet is an excellent source of polycatechin polyphenols, a group of antioxidants that act on free radicals. These free radicals have harmful effects on the body since they are the major causes of diseases and aging. With polycatechin polyphenols, a person has a better chance of avoiding ailments and keeping himself healthy for a much longer period of time.
Another antioxidant in the green tea diet is also being studied as a potential cure for cancer. Epigallocatechin gallate or EGCG found in the diet has been discovered to destroy cancer cells while keeping surrounding healthy cells unharmed.
The EGCG also acts with another compound, caffeine (a small amount of this is found in green tea). The interaction of these two compounds causes the diet to promote thermogenesis in the body.
It has been noted by a study published in the American Journal of Clinical Nutrition that with the consumption of the green tea diet, the body’s total 24-hour energy expenditure is increased by up to four percent. This is roughly equivalent to losing more than 10 pounds of weight a month.
The diet helps increase the body’s metabolic rates. With its thermogenic properties, it is only natural that it can also promote faster metabolism of fats and sugars. Excess glucose found in the body is turned into fats by the hormone insulin. Because green tea has an inhibiting effect on insulin, it therefore helps keep sugar from being stored as fats and instead, send them directly into the muscles for immediate use.
The Downside
Although the diet has a reputation for boosting health, scientific proofs of its health benefits are still somewhat mixed. However, in an article published in the Archives of Internal Medicine, American researchers collaborated with their Chinese counterparts to discuss the beneficial effects of green tea diet on cholesterol levels.
Using 240 men and women (average age 55) who possess mild to moderately high LDL cholesterol levels, the researchers instructed them to retain their usual low-fat diet, green tea diet intake, and activity levels. After twelve weeks, it was found that those who consumed the green tea diet extract with their regular meals lost more than fifteen percent of their total LDL cholesterol levels.
Although the researchers never explained how the green tea diet may influence cholesterol levels, previous studies have shown that certain compounds play a role in reducing the amount of cholesterol absorbed by the body, increasing amount of cholesterol excreted, and thus keeping cholesterol from being stored in the liver.
Subsequent studies were made to test the findings of the first group of researchers. Their results were contradictory. They found there was no significant effect on the cholesterol profiles of their subjects.
There is no such thing as a miracle diet. The green tea diet like all other diets needs a lot of work and input from those who enroll in it. It requires both discipline and determination for it to make any significant impact on your weight loss goals.

Many diet formulas are just fads that don’t work. The Chi Tea Weight Loss Program is based on scientifically effective ingredients that help you lose weight and keep it off.Dieters are always searching for the holy grail of weight loss — a healthy product that melts fat effortlessly. As a result, ads for miracle diet pills and weight loss methods are everywhere. At best, many of the diet formulas that people try are ineffective and disappointing; and at worst, some have major side effects and can cause serious damage to your health. Ephedra, or ma huang, for example, is a stimulant that can cause jittery behavior or even heart trouble. It’s not a true thermogenic, and in fact, it’s dangerous. Unlike other herbal products like ephedra and prescription drugs for obesity, green tea extract does not increase heart rates or raise blood pressure.The Chi Tea Weight Loss Program is based on clinical evidence and healthy results. The products in the Chi Tea Weight Loss Program have been scientifcally proven to help you lose weight naturally and safely. A study published in the American Journal of Clinical Nutrition found that green tea extract resulted in a significant increase in metabolic energy expenditure and a significant effect on fat oxidation. A 4% overall increase in energy expenditure was attributed to the green tea extract. What’s more, the researches found that the extra expenditure occurred during the daytime, which led them to conclude that since thermogenesis (the body’s own rate of burning calories) contributes 8-10% of daily energy expenditure in a typical subject, that this 4% overall increase in energy expenditure due to the green tea actually translated to a 35-43% increase in daytime thermogenesis! Chi Tea products harness these impressive thermogenic properties.So what is the Chi Tea Weight Loss Program? It consists of three fat-burning supplements: Ultimate Green Tea, Ener-Chi Cafe and Ener-Chi Sport.Chi Tea Ultimate Green Tea is a concentrated extract that uses 50 pounds of premium quality green tea leaves per pound of product. This means that drinking 1 cup of Ultimate Green Tea is equal to 12-15 cups of regular teabag green tea! Chi Tea Ultimate Green Tea contains more than 95% polyphenol antioxidants and 62% fat-fighting EGCG. The Ener-Chi collection consists of two natural energy elixirs filled with fatigue-blasting vitamins and herbal extracts. Ener-Chi has a high concentration of green tea and other fat busters like L-Carnitine which help to rapidly melt away stored fat in your hips, thighs and belly.
