It can stop you from eating to much, or to little, for example if you see you've eaten to many calories in a day it can stop you from eating more. It can also convince you too eat a little more if you're under the recommended calorie intake a day. If you're under working yourself it can convince you to work out a little more, but also tell you to take a break if you're overworking yourself.
hope this helps :)
