According to a recent study, people who have high blood caffeine levels are more likely to maintain their weight. The rate at which the body metabolizes caffeine can affect weight, according to researchers at Imperial College London. If more coffee can aid in weight loss, more research is required to confirm this.
Six lengthy studies involving close to 10,000 participants totaled the study. People with higher blood caffeine levels had lower BMIs, according to the study’s findings. In addition, there were fewer chances of developing type 2 diabetes.
In contrast, research has shown that rapid caffeine metabolism is associated with a slightly higher BMI in people with type 2 diabetes.
A clinical scientist at American College London named Dr. Dipinder Gill says that 95% of the caffeine we take in is broken down by an enzyme. Two genes that influence the expression and function of this enzyme are CYP1A2 and AHR.
According to him, studies using these genetic variations—which affect how quickly or slowly people metabolize caffeine—showed that slow metabolizers had higher levels of the drug in their blood and that consuming more of it lowered body mass index and diabetes risks.
