A busy, stressed-out mind does not support your body's needs. In fact, stress can actually slow your metabolism down. According to Sports Club/LA trainer and lifestyle coach Julie Barrett, MS, RD, when our bodies are under stress, "our adrenal glands pump out excessive amounts of the stress hormone cortisol, causing an imbalance in our bodies' natural hormonal rhythms," which reduces your ability to burn fat.
Make sure you're spending a little bit of time every day to practice self-care. Whether it's a long bath, a quiet meditation, or moving through some relaxing yoga poses, don't think of these things as an extraneous luxury. Self-care is essential, and it is time well spent.
