The primary reason behind coffee's energizing effect is its caffeine content.
Caffeine blocks adenosine, a neurotransmitter that promotes sleepiness, leading
to increased alertness, improved focus, and enhanced cognitive function.
Studies suggest caffeine can increase fat burning during exercise, potentially
improving performance and endurance.
Some research indicates caffeine may improve muscle strength and power output,
particularly during high-intensity workouts.
Moderate coffee consumption is associated with a decreased risk of developing
type 2 diabetes, potentially due to improved insulin sensitivity.
Studies suggest coffee may offer some protection against neurodegenerative
diseases like Parkinson's and Alzheimer's, although more research is needed.
