What to know before purchasing a fat burner

Although some ingredients within fat burner supplements may support weight loss, they can not cause it directly. It is crucial to be in a caloric deficit if you are trying to shed pounds through diet and/or increased physical activity.

It is also important to note that almost all fat burner supplements contain caffeine. According to the FDA recommendations, the maximum upper limit of caffeine per day is 400 mg in healthy adults. Depending on their healthcare provider's advice, some individuals may need to consume less.

Caffeine should also be consumed in the first half of the day as it can have a negative impact on sleep. There are also caffeine-free fat burners that work well in night time.

Some fat burners have been linked to serious adverse events. For instance, green tea extract has been linked to acute liver injuries.

If you are unable to lose weight, it is important to consult your doctor as certain conditions may be impacting your efforts.

Separating facts from fiction about female fat burners

If you are looking for the best fat-burning supplements for women, you may have come across a wide range of product options that promise hassle-free fat loss. However, dietary supplements can not cause weight loss directly, and may only support your efforts.

Please be cautious when choosing dietary supplements as they are not regulated by the FDA in the same way prescription medications are. This means that the efficacy of fat burners may vary greatly.

For those who want to make a more informed decision, we have prepared a short summary of what ingredients may be helpful in weight loss in the section.

The science behind fat burner supplements

In general, fat burners contain a wide range of ingredients, typically between 5 to 20. Most of these ingredients have very little scientific backing as there is a lack of studies on weight loss supplements.

The two most widely studied ingredients for weight loss remain caffeine and green tea extract. With both having been studied in humans, the common proposition is that these two compounds may speed up metabolism. Moreover, caffeine is often included in pre-workout formulas due to its potential to boost performance in the gym.

Other ingredients have been studied sparsely, thus we need more studies to confirm their benefits.

For example, chili pepper extract, rich in the active compound capsaicin, has also been investigated as a potential aid for weight management. One study indicates that consuming capsaicinoids prior to a meal might assist in reducing overall food intake.

Another common ingredient found in fat burning supplements is Grains of Paradise — a spice that belongs to the ginger family. One clinical trial in 19 healthy women suggested that this ingredient may help to reduce body fat.

When it comes to other ingredients in fat burners, the claims of their properties are usually drawn from animal studies. For instance, this includes black pepper extract which is promoted to be useful for weight loss because of early findings of rat studies.

Keep in mind that although some research studies are pointing out certain ingredients as potentially being able to aid weight loss, their effects are modest.

Who shouldn't take fat burners

Not everyone should take fat burners because of certain active ingredients within them. If you have any underlying condition or are taking medications or supplements, consult your physician before purchasing weight loss supplements.

Below, we will name a few examples of groups of people that are advised against taking fat burners.

Individuals with diabetes

If you have been diagnosed with diabetes, be cautious before purchasing fat-loss supplements. One research study suggests that fat burners may have a negative impact on glucose metabolism and insulin resistance. According to the authors, this unwanted result may be attributed to caffeine or a combination of other ingredients tested in the clinical trial.

Pregnant or breastfeeding individuals

Due to limited evidence of safety, fat burners are not recommended during pregnancy. Moreover, caution should be exercised if you are breastfeeding as well.

Individuals with hypertension

Caffeine, a common ingredient in weight loss supplements, may increase your blood pressure. It applies both to caffeine from natural sources such as coffee and dietary supplements.

Although the recommended limit of caffeine per day in healthy adults is 400 milligrams taken sparsely throughout the day, you may want to consult your physician about whether you should consume less than that if you have hypertension.
