[Health Channel/Comprehensive Report]Many people choose to use fasting to lose weight in order to have a better body. However, many people criticize that fasting may affect female hormones. In response, the University of Illinois at Chicago research team tracked premenopausal and postmenopausal obese women on intermittent fasting for 8 weeks. It was found that DHEA (dehydrocorticosterone, a hormone used to improve ovarian function and egg quality) was significantly lower in premenopausal and postmenopausal women, by about 14 percent.
according to”Science Daily“(Science Daily) reported that the University of Illinois at Chicago published a study on “Obesity” and presented new evidence. The researchers followed obese women before and after menopause for eight weeks using intermittent fasting. They obtained differences in DHEA hormones by analyzing blood sample data.
UIC nutrition professor Krista Varady and her team found that sex hormone binding globulin, testosterone, and androstenone remained unchanged in fasting women’s female hormones, but DHEA decreased after 8 weeks about 14%. While the drop in DHEA was the study’s most important finding, at the end of week 8, DHEA levels were still within normal ranges.
Varady points out that studies show that for premenopausal women, fasting can lead to weight loss, but also a small decrease in DHEA. DHEA declines in post-menopausal women can be worrying, she said, because menopause already causes a dramatic drop in estrogen, the main component of estrogen. However, there are also survey reports showing that there are no side effects associated with low estrogen.
Varady also said that since high DHEA is associated with breast cancer risk, a modest decrease may help reduce cancer risk in women.
Using different alternate-day fasting and time-restricted eating strategies, the study looked at thousands of pre- and post-menopausal women who naturally cut calories by reducing food intake and timing. Most of the current research on the negative effects of intermittent fasting comes from studies in mice or rats. Varady said that more research will be needed in the future to explore the effects of intermittent fasting on the human body.
