The study was carried out by researchers from Uppsala University in Sweden, Imperial College London, University of Bristol and the London School of Hygiene and Tropical Medicine. They used a statistical technique called Mendelian randomization, which examines cause and effect using genetic evidence. For this study, researchers looked at 10,000 people (mostly of European descent) with genetic traits associated with how quickly the body metabolizes caffeine.

Does this study prove that drinking more coffee will automatically help with weight loss and reduce the risk of diabetes? No. It just turned out that almost half of the reduction in the risk of type 2 diabetes was due to weight loss. Caffeine can help burn fat, boost metabolism, and reduce appetite, which may play a role in this condition. Dr. Dipender Gill, one of the study’s senior authors, noted that “Further clinical study is warranted before individuals should use these results to guide their dietary preferences.”
People with certain genetic traits metabolize caffeine more slowly and usually drink less coffee. But they have high levels of caffeine in their blood. The researchers found that such people tended to have a lower body mass index, body fat mass and risk of type 2 diabetes. The study notes that previous observational studies have shown that coffee consumption (3-5 cups per day) may be associated with an increased risk of type 2 diabetes and cardiovascular disease. However, long-term studies are required to investigate this further.

Dr Stephen Lawrence, an associate clinical professor at the University of Warwick’s School of Medicine, said Mendelian estimation was a “relatively new technique” and “vulnerable to bias”, The Guardian reported. The authors of the study themselves admitted that their findings may not apply to non-European populations, as the study was limited to people of predominantly European descent.
