Caffeine can indeed affect metabolism and fat oxidation. It stimulates the central nervous system, potentially increasing metabolic rate. However, individual responses can vary. Tolerance buildup is common, which might reduce its effectiveness over time. Combining caffeine with exercise tends to enhance its fat-burning effects, as physical activity elevates metabolic demand.
In terms of timing, some find morning consumption beneficial since it aligns with natural cortisol rhythms, possibly supporting more effective metabolism. As for forms, both coffee and supplements can be effective, but they might differ in caffeine dosage and bioavailability.
Monitoring your body’s response and adjusting intake based on personal tolerance is key. It’s important to consider overall health and avoid overconsumption to prevent adverse effects such as jitteriness or sleep disruption.
