“When a woman feels safe with her partner, the level of cortisol—the body’s primary stress hormone—drops. At the same time, the production of oxytocin and serotonin increases.

These changes are completely natural,” says Kate Novaya, an integrative doctor and self-described 'biohacker' who goes by @doctor.novik on Instagram.
Kate’s now-viral Instagram post, where she claimed that women tend to gain weight in healthy relationships, has triggered a fierce online debate.
