It also wreaks havoc on the body, causing it to produce excess cortisol, which can result in a unhealthy abdominal fat that creates an unattractive potbelly.Reduce your stress by taking time out of your day to relax in a way that works for you. Try meditating, going for a walk in a quiet park or doing a few deep breathing exercises from time to time. You can also get rid of stress by working out. Do an activity you enjoy to get the most benefits.Set short-term goalsWhen striving for a beauty or fitness outcome, you may think to yourself, "I'd like to fit in a pair of size 6 jeans" or "I want to have perfect skin."
