Drinking coffee can speed up your metabolism. Tatiana Romanenko, therapist and cardiologist, spoke about this. As the expert explained in the commentary to Arguments and Facts, caffeine inhibits the enzyme PDE (phosphodiesterase). This increases the breakdown of glycogen, which is also known as an easily utilized source of energy.
“Liver glycogen is broken down when the concentration of glucose in the blood decreases, primarily we are talking about breaks between meals,” the doctor explained.
She added that after 12-18 hours of starvation, glycogen stores decrease. It is also possible to reduce its amount in the muscles with the help of physical activity.
According to the doctor, caffeine has the ability to inhibit phosphodiesterase and stimulate metabolism in the body and tissues. As a result, as Romanenko pointed out, energy is consumed from fats.
At the same time, the doctor recalled that excessive consumption of the drink can lead to insomnia, tachycardia, arrhythmias, nausea, and called for moderation when including coffee in the diet.
