Women need more of this mineral because they lose an average of 15 to 20 milligrams of iron each month during menstruation. Without enough iron, iron deficiency anemia can develop and cause symptoms that include fatigue and headaches. After menopause, body iron generally increases. Therefore, iron deficiency in women older than 50 years of age may indicate blood loss from another source and should be checked by a physician.
Three related targets of MDG5 were adolescent birth rate, contraceptive prevalence and unmet need for family planning (where prevalence+unmet need = total need), which were monitored by the Population Division of the UN Department of Economic and Social Affairs.[64] Contraceptive use was part of Goal 5B (universal access to reproductive health), as Indicator 5.3.[65] The evaluation of MDG5 in 2015 showed that amongst couples usage had increased worldwide from 55% to 64%. with one of the largest increases in Subsaharan Africa (13 to 28%). The corollary, unmet need, declined slightly worldwide (15 to 12%).[37] In 2015 these targets became part of SDG5 (gender equality and empowerment) under Target 5.6: Ensure universal access to sexual and reproductive health and reproductive rights, where Indicator 5.6.1 is the proportion of women aged 15–49 years who make their own informed decisions regarding sexual relations, contraceptive use and reproductive health care (p. 31).[66]
After 40, your hormone levels (estrogen) drop. This causes your insulin (hormone that helps your body use sugar) rise. Your thyroid levels go down. This combination makes you hungrier. You end up eating more and burning fewer calories. Much of the weight gain occurs around your belly. Eat more foods with fiber (berries, whole grains, nuts) to fill you up and help you eat less. Aim for 25 grams of fiber each day after the age of 40. Other ways to increase your metabolism include:

In addition to diet, exercise and other lifestyle factors can also play an important role in bone health. Smoking and drinking too much alcohol can increase your chances of developing osteoporosis, while weight-bearing exercise (such as walking, dancing, yoga, or lifting weights) can lower your risk. Strength or resistance training—using machines, free weights, elastic bands, or your own body weight—can be especially effective in helping to prevent loss of bone mass as you age.
