Introduction:Higher consumption of coffee and caffeine has been linked to less weight gain and lower body mass index in prospective cohort studies, usually with exposure assessment limited to baseline values. As BMI is a proxy for adiposity but does not capture fat tissue or its metabolically relevant distribution, precise measurements of distinct adipose tissues are needed, so the cardiometabolic impact of an anti-obesity effect can be assessed.Hypothesis:We assessed the hypothesis that an increase in coffee consumption is associated with a reduction in body fat, in particular with trunk fat and visceral adipose tissue (VAT).Methods:In the setting of a large, randomized trial of Mediterranean diet and physical activity intervention, we evaluated 1483 participants with metabolic syndrome. Changes in the consumption of caffeinated and decaffeinated coffee were derived from validated food frequency questionnaires at baseline, 6 months and yearly during follow-up. Fat tissue was measured with dual x-ray absorptiometry at baseline and after 6, 12 months and three years. Linear multilevel mixed effect models were used to investigate the relationship between changes in coffee consumption and corresponding concurrent changes in fat tissue over three years.Results:After adjustment for intervention group, and other potential confounders, an increase in caffeinated coffee consumption from no or infrequent consumption (≤ 3 cups/ month) to moderate consumption (1-7 cups/week) was associated with reductions in total body fat (Δ z-score: -0.06; 95 % CI: -0.11 to -0.02), trunk fat (Δ z-score: -0.07; 95 % CI: -0.12 to -0.02), and VAT (Δ z-score: -0.07; 95 % CI: -0.13 to -0.01). However, changes to even higher levels (> 1 cup/day) showed no significant association.Conclusions:Moderate consumption of caffeinated coffee, but not high consumption, was associated with reductions in total body fat, trunk fat and VAT in a Mediterranean cohort with metabolic syndrome. Decaffeinated coffee was not linked to adiposity indicators. In conclusion, moderate consumption of caffeinated coffee may be part of a weight management strategy. |
