the reality TV star more famous for her extreme manipulation of her looks than her short-lived part on The Hills
, reported earlier this year that she had lost 30 pounds
by dieting and working out 14 hours a day. Her reasoning? She had to wear a bikini to host a pool party. While there's nothing wrong with wanting to look good in your swimsuit, exercising excessively can lead to
injury, insomnia, depression, heart attacks and strokes, electrolyte imbalances, and even death.
Dr. Elizabeth Lyster, a gynecologist specializing in women's hormones adds, "If exercise is experienced as [too] stressful, this can stress the adrenal glands. Adrenal glands make cortisol in response to stress. When there is too much cortisol release, the body goes into the "save" mode and will retain weight, especially around the midsection."
