It may also improve muscle contractions and reduce the perceived rate of exertion, making a workout feel easier. This allows one to exercise harder for longer and delay muscle exhaustion. Nonetheless, most studies show that these effects are short-term rather than long-lasting.Ĭaffeine may also help improve exercise performance by increasing the use of fat as fuel and preserving glucose in the muscles for longer periods of time. Although this only equates to the amount of energy in a piece of fruit, it can be meaningful in the long term. Some research shows that the stimulant may help increase metabolism by 11 percent and fat burn by 13 percent, which would mean burning an extra 70-100 calories per day. In other studies, caffeine helped lower the risk of depression and risk of suicide.Ĭaffeine is also associated with potentially boosting metabolism and fat burning capability due to the stimulation of the nervous system. In one study, participants who ingested 40-450 mg of caffeine demonstrated improved alertness, short-term memory recall, and reaction time. It does this by acting on the three neurotransmitters already discussed (adenosine, dopamine, and norepinephrine) and shifting their communication messaging.
