A study published in the journal Nutrients found that moderate coffee intake before moderate-intensity endurance exercise can help increase fat oxidation. In other words, the body uses more excess fat for energy during exercise, according to the health website Medical News Today (UK).

Coffee helps the body mobilize energy from fat
Caffeine in coffee helps the body mobilize energy from fat through many complex biological mechanisms. First, caffeine stimulates the sympathetic nervous system, increasing the concentration of adrenaline hormone in the blood. This hormone promotes the breakdown of triglycerides in adipose tissue into free fatty acids for the body to use as energy.
Additionally, caffeine dilates blood vessels and increases blood flow to skeletal muscles. This allows oxygen and fatty acids to travel more quickly to skeletal muscles, thereby optimizing fat oxidation.
Caffeine not only increases fat oxidation, but also increases the maximum amount of oxygen the body can absorb. This suggests that caffeine may help the body use more fat instead of carbohydrates, especially during moderate-intensity endurance exercise. Additionally, caffeine also activates muscle cells, improving the transport of free fatty acids to muscle tissue, supporting more efficient fat burning.
However, with short-duration, high-intensity, and low-continuity abdominal exercises such as sit-ups or planks, the body mainly uses glycogen instead of fat for energy. Glycogen is a stored form of carbohydrate. Therefore, the fat-burning effect of caffeine may be limited if the workout is not long enough or not combined with running, cycling, or swimming.
One thing to keep in mind is that if you only do abdominal exercises, the fat burning effect from caffeine is often much lower than endurance exercises such as running or cycling. Therefore, it is best to combine abdominal exercises with light cardio or extended planks to optimize the fat burning process with the support of caffeine.
Additionally, the body's response to caffeine can vary from person to person, especially for those who are used to drinking coffee every day. They may feel less of the fat-burning effects than others.
It's important to note that caffeine isn't a substitute for overall diet and exercise. If you're already eating too many calories or not getting enough sleep, adding caffeine won't make a significant difference, according to Medical News Today .
