Frazer is devoted to her dogs, and loves spending time with them. "Any type of walking has increased mental and physical health benefits, but studies have shown that walking in nature is more effective than taking a stroll through the city," says Nancy MacGregor, MA, ATR-BC, LPC, ACS.

Frazer loves the many health benefits of spending time at the beach. "I make it a point to go on a beach walk with my husband and our two dogs at least twice a week," says Christine Scott-Hudson, MA, LMFT, ATR, a psychotherapist and art therapist in Santa Barbara, California. "Going on a beach walk has restorative powers that exercising inside of a gym just does not have. Looking out onto the blue water is both relaxing and healing."

Frazer enjoys scrambled eggs for a quick, healthy meal. "Both the egg white and yolk are rich in nutrients, including proteins, vitamins and minerals," says registered nutritionist Jo Lewin. "The yolk contains fat-soluble vitamins (such as vitamins D and E) and essential fatty acids; while most of the protein is found in the egg white."

Frazer loves hiking and exploring, especially when traveling to new places. "Hiking allows us to disconnect from the hustle and bustle of our everyday lives," MacGregor says. "When we are out in nature, we are provided with a peaceful escape from everyday life. Research has shown that the constant use of technology and the noise from urban areas, disturb our focus, increases anxiety, and causes overwhelming effects on the body.

Frazer says she still has body dysmorphia after undergoing a gastric bypass at age 22. "[The surgery] worked out really well for me, I've had a lot happier of a life. Not that my body image is great but it's better than it was and I'm a lot happier for it," she says.
