The study was conducted by researchers from Uppsala University in Sweden, Imperial College London, the University of Bristol, and the London School of Hygiene & Tropical Medicine. They used a statistical technique called Mendelian randomisation, which studies cause and effect using genetic evidence. In this study, researchers considered 10,000 people (mostly of European descent) who had genetic traits linked to how quickly caffeine is metabolized in the body.

Does this study prove that drinking more coffee will automatically help you lose weight and reduce your risk of diabetes? No, it simply found that nearly half of the reduction in type 2 diabetes risk was driven by weight loss. Caffeine can help burn fat, increase metabolism, and reduce appetite, which may play a role in this condition. Dr. Dipinder Gill, one of the study’s senior authors, determined that “further clinical study is warranted before individuals use these findings to guide their dietary preferences.”
People with certain genetic traits metabolize caffeine more slowly and usually drink less coffee. But they do have high levels of caffeine in their blood. The researchers found that these people tend to have a lower body mass index, body fat mass, and a lower risk of developing type 2 diabetes. The study noted that in the past, observational studies have suggested that coffee consumption (3-5 cups per day) could be associated with a lower risk of type 2 diabetes and cardiovascular disease. However, long-term studies are needed to further investigate this.

Dr Stephen Lawrence, associate professor at the University of Warwick Medical School, said the Mendelian assessment was a “relatively new technique” and was “prone to bias”, reports The Guardian. The study authors acknowledged that their findings may not apply to non-European populations, as the study was restricted to people of mainly European descent.
