Caffeine is the most popular and widely consumed substance with ergogenic effect. Through coffee and other foods or beverages we can incorporate it into our diet and a recent study confirms that its consumption prior to exercise increases fat burning.
The recently published research aimed to analyze diurnal variation in fat oxidation and the influence of acute pre-exercise caffeine consumption.
The results indicate that the rate of fat oxidation is higher during the afternoon but caffeine, consumed 30 minutes before exercise, boosts fat burning, regardless of the time of day.
Although the research in question is very small and only included 15 men with an average age of 32 years, it should be considered that it is a triple-blind, placebo-controlled study, which increases the value of the results.
On the other hand, the study leaves us with the conclusion that caffeine consumed in quantities of 3 mg per kilo of body weight, which can be obtained with a large cup of filter coffee or a concentrated coffee, about 30 minutes before moderate intensity exercise, considerably increases fat burning.
Thus, if we seek to optimize fat burning, we recommend exercise in the afternoon, of moderate intensity and after the intake of caffeine that boosts lipid oxidation in the body.
