Abstract

In the United States, people have come to rely heavily on everyday caffeine consumption for numerous reasons. Inspired by this profound use, our group investigated the interaction between macronutrient metabolism and caffeine consumption. We further explored how macronutrient metabolism is impacted when caffeine is ingested with food. Three investigators independently conducted a literature review. Research databases were searched between July 2015 and January 2016, using the metabolic effects of caffeine, carbohydrates, protein, metabolism, and insulin response to caffeine as keywords. Three studies investigated glucose intake with coffee supplementation. These trials resulted in decreased insulin sensitivity, glucose disposal, and absorption in adipose cells. Five papers described coffee and lipid metabolism. They showed caffeine reduced body fat mass by adipose tissue lipolysis, in both animal and human trials. In contrast, there was no impact on fatty acid uptake in skeletal muscle reaction as well as subsequent metabolism during exercise. Few studies focused on the relationship between caffeine and protein. Three trials assessed co-ingestion of carbohydrates and proteins with caffeine, and reported endurance performance was enhanced. There is a clear gap in the literature, and studies investigating the effects of caffeine on protein metabolism are needed. Trials investigating the impact of caffeine intake on carbohydrate and lipid metabolism shows beneficial or negligible effects. Future work should focus on protein metabolism and overall metabolic impact of caffeine consumption with mixed macronutrient meals.
