No, Monster does not break a fast. Fasting is an ancient practice that has been used for religious and spiritual purposes for centuries. There are many different types of fasting, but the most common is intermittent fasting, which is when you restrict your food intake for a set period of time. Some people fast for 24 hours, while others may only eat during certain hours of the day or week. There are many health benefits associated with fasting, including weight loss, improved mental clarity and decreased inflammation.
