The ability to not eat food for prolonged periods of time (fasting) is one of the most important and advantageous one you can train for and get used to.
It allows you not only to heal almost any health issue, become strong and ressilient, repair and refresh your brain, and clean and reset your body, but also lose any amount of fat and become shredded in the fastest possible way. Also, it balances the hormones and all the processes in the organism.
The price you pay for all these benefits is the discomfort you will need to endure.
