The Impact of Coffee on Metabolism

September 7, 2019 by

Many struggle with obesity. In fact, recent statistics show that 71.6% of the U.S. population is either overweight or obese. It is important to know that you can’t out-exercise a poor diet, and you have to combine exercise with healthy eating in order to maintain a healthy weight.

However, the number of active dieters since 2015 has declined, as seen in product purchasing trends of diet pills, supplements, shakes, frozen entrees, and medical weight loss clinics.

There are a lot of factors that can contribute to your weight loss ability, such as getting high-quality sleep every night, which supports a healthy gut microbiome. Also, choosing to consume more fruits and vegetables and less processed junk food greatly contributes to your weight. The most recent research has shown that drinking coffee may impact your metabolism and reduce the amount of your active brown fat.

Coffee can stimulate brown fat because brown adipose tissue can generate heat and burn sugar and fats. Having a balance in energy can prevent the development of weight gain or obesity, and while exercise may get rid of some energy, your body also produces heat by burning energy.

Caffeine may reduce the potential for weight gain or obesity and improve insulin sensitivity because it is of the systems that burns brown fat. Studies have looked at the impact of caffeine on brown adipose tissue both in a test tube and in humans.

Past studies have demonstrated the activation of brown adipose tissue through nutrients and exposure to cold. Caffeine causes an upregulation of UCP1 in obese mice, however, the direct impact that it has on humans is unknown.

Researchers used several tests to analyze their data and then studied nine healthy human volunteers with a normal BMI. The subjects either drank a caffeinated beverage or water and then stayed seated for 30 minutes.

The researchers found that those who drank caffeine had an increase in the expression of UCP1. They also analyzed the thermal imaging completed 30 minutes after the subjects drank their beverage against the images taken before.

The images showed an increase in the brown adipose tissue temperature in adults after drinking coffee, while there was not an increase in heat production in brown adipose tissue in those who drank water.

This was the first study to look at the effect of drinking coffee on neck fat. Researchers already knew that brown fat was mainly located in the neck region, so they could take a picture of someone directly after drinking to see if the brown fat increased in temperature. Because the results were positive, researchers now need to make sure that caffeine is in fact the ingredient in coffee that is the stimulus or if it is a different component that helps with the activation of brown fat.

However, the researchers did believe that their results suggested that the caffeine in a standard cup of coffee may increase the metabolic rate and enhance brown adipose tissue function, which they believe could lead to weight loss.

Coffee may also impact your metabolism. New studies that looked at the impacts of coffee on one’s health are often reported. Some reports show that caffeine may increase your life span, while others believe caffeine can increase your potential risk for health danger.

One recent study showed that coffee changed significantly more metabolites than they had previously realized. After you consume food or have a drink, your body makes metabolites, which are chemicals that help make use of the calories. An increase in affected metabolites may have an impact on the amount of effects that coffee has on your body.

By evaluating the blood of those who drink coffee for the number and type of metabolites, researchers have found that the levels of 115 metabolites were changed by consuming coffee, and 82 of these changes were known to impact 33 biological pathways.

Researchers also discovered three new links to coffee and they found metabolites related to the androsteroid system, which suggested to the researchers that coffee could possibly help eliminate steroids from your body. This can help reduce cancers that are affected by steroid levels.

The association between coffee, weight loss, and a reduced risk of diabetes is often thought to be caused by caffeine’s ability to boost the metabolism of fat, and new findings have linked coffee to endocannabinoids, which offers alternative explanations that can be studied more to help people lose weight.
