Clinical Definition
Caffeine is a methylxanthine that acts as a non-selective adenosine receptor antagonist, acutely increasing thermogenesis, fat oxidation, and energy expenditure while modestly suppressing appetite. Tolerance develops with habitual use, and high doses can raise heart rate, blood pressure, and anxiety, limiting its clinical role in weight management.
Key Insight
Why It Matters
