Spanish scientists at the University of Granada recently found that drinking "the equivalent of a strong coffee" in the proportion of 3 milligrams per 1 kilogram of body weight half of an hour before starting an aerobic exercise would noticeably increase the rate of fat oxidation in adult men.
Additionally, this study, which was published in the Journal of the International Society of Sports Nutrition, shows that aerobic exercise that came after coffee consumption is more effective in the afternoon than in the mornings.
As part of the study, a group of middle-aged men (around 32) was running exercises under several specific conditions, having received either a dose of caffeine or placebo before the start either at 8 a.m. or at 5 p.m.
Scientist ended up with several interesting outputs, such as:
- Fat oxidization, which causes the human body to burn the highest amount of fat, regardless of caffeine usage, was at its best in the afternoon, not in the morning.
- Morning exercises caused more fat oxidization if caffeine was used before the start.
- According to data, consuming caffeine in the morning somewhat increases fat oxidation during afternoon exercises.
Taking it short, afternoon exercises paired with a good dose of caffeine is the best way to burn more fat that includes coffee drinking. What happens if subjects will increase caffeine dosage and exercise intensity is unknown yet and should be investigated in further research
