Metabolism is a complicated system that includes almost every chemical reaction that takes place within your cells and provides energy for most of your body's vital processes. In other words, your metabolism encompasses way more than the process of burning up the calories from the food you eat, which means that its efficiency, or "speed," is reliant on many different factors.
The speed of your metabolism is dependent on a variety of factors, including genetics, gender, age and your percentage of lean body mass. Thanks to genetics, some people have "speedier" metabolisms than others. However, there are some scientifically backed things you can do to make yours work a little more quickly.
Among these things are certain drinks that can temporarily increase the speed of your metabolism, which may allow you to lose weight faster.
