Researchers at the University of Francisco de Vitoria have uncovered a clear link between caffeine intake and the body’s fat-burning processes. The team published their findings in a nutrition-focused periodical, drawing on a broad analysis of existing research.
In their review, scientists assessed past work on how caffeine influences fat metabolism. They screened 182 sources in total, comprising 157 research articles and 25 reviews. The results suggest that caffeine, regardless of its form, activates the sympathetic nervous system. This activation can raise heart rate, widen airways, increase gut motility in the esophagus, dilate pupils, boost sweat production, and elevate blood pressure. The physiological effects were observed across several delivery methods, including coffee, energy drinks, and caffeine supplements in pill form.
The data indicate that caffeine promotes the release of fatty acids into the bloodstream and enhances lipolysis, a metabolic process that breaks fats down into usable fatty acids. This mechanism supports weight management efforts when used as part of a balanced lifestyle.
Experts also emphasized moderation. High blood pressure, sleep disturbances, and anxiety are potential concerns if caffeine is consumed in excess. For some individuals, caffeine may interact with existing health conditions, so thoughtful dosing is advised.
Some biologists have warned that global coffee production could face shifts in the future due to various agricultural and market factors. This context matters for consumers who rely on caffeine-containing products for daily routines and workouts. [Citation: University of Francisco de Vitoria research team, nutrition journal]
