Before you start a juice cleanse diet, know that drastically restricting your caloric intake to drop pounds may backfire: In a 2010 study, women placed on a 1,200-calorie diet for three weeks had elevated levels of cortisol, our primary stress hormone. [Tweet this fact!] Chronic stress has been associated with an increased risk of weight gain as well as coronary heart disease, hypertension, diabetes, cancer, and impaired immune functioning. 
Another major difference between the January covers we picked up: the scantily clad women versus coverboy Mark Wahlberg, who got to keep all of his clothes on. Shields (“Fitter Than Ever At 52!”) and Menounos (“Huge career. New fiancé. Then a brain tumor” right next to the shot of her in a teeny red bikini.) were not so fortunate. Maybe it’s on purpose: Menounos appears happy to show off her huge engagement rock as well as her impossibly flat abs, while Shields has been modeling since she was 11 months old, although hardly in such an unappealing posture as this one.
When trying to adopt new healthy habits, it's important to work around other long-standing practices that could sabotage your efforts if overlooked. For example, if you are a morning person, working out in the a.m. is likely best, but if you’re a night person, exercise after work, says Tara Stiles, owner of Strala Yoga in New York City. [Tweet at Tara!]“Don't try to become one or the other if it's not natural to you. You're more likely to stick to it if you like the time of day and the whole experience.”
The U.S. Public Health Service recommends that all women of childbearing age consume 400 mcg of folic acid (a B vitamin) daily to reduce their risk of having a pregnancy affected with spina bifida or other neural-tube defects. Women who are actively trying to get pregnant should consume 600 mcg, and lactating women should consumer 500 mcg. Women of childbearing age should also take care to meet the daily requirements for calcium, fiber, iron, protein and vitamin D. Discuss supplements with a health care professional, however. Iron and vitamin D in particular can be dangerous in high amounts.
Fortunately, this trend is not across the board; on the cover of the January issue of Shape, Mandy Moore is in a black leather jacket so that her ensemble kind of resembles Wahlberg’s. This is not to say that Shape always covers up its cover women: Kate Walsh (right) was famously naked on her Shape cover (“How She Stays This Hot At 44!”), while The Biggest Loser’s Alison Sweeney also favored a red bikini.
Although creating financial incentives to lose weight isn't a new idea, now we know cashing in to stay motivated works long-term. In the longest study yet on this topic, Mayo Clinic researchers weighed 100 people monthly for one year, offering half the group $20 per pound lost plus a $20 penalty for every pound gained. Those in the monetary group dropped an average of nine pounds by the end of the year, while non-paid participants shed about two pounds. If you’re ready to gamble away weight, consider sites such as Healthywage, FatBet, or stickK.
The delivery platforms of birth spacing and family planning interventions were often associated with health clinics and community health posts (148–150). Many interventions targeted lactating women during the follow-up with their young children (148, 151–153). Home visits by community health workers and service provision at community health posts and mobile clinics were also used to target women and adolescents who were married, and were found to be effective at increasing use of contraception (150, 154). School-based programs were also effective at reaching adolescent girls and increased their knowledge about contraceptives and sexually transmitted infections, use of contraception, and treatment of sexually transmitted infections (155). In high-income settings, school-based interventions were most effective at reducing pregnancies and repeated pregnancies among adolescents when contraception was also available on-site (107). This might have implications for their effectiveness in low- and middle-income countries, as well. In addition, formative work of 2 ongoing studies suggested that mass media, mobile devices, texting, and community mobilization could also be used as platforms to reach adolescent girls and women of reproductive age (156, 157). Community-based programs that target men, families, and communities, beyond those that reach married and postpartum women alone, have potential to change cultural norms and enhance women's health outcomes; however, these are not well captured in the literature.
If you usually head to the gym after work, take heed: Mental exhaustion can make you feel physically exhausted, even when you have plenty of energy, reports a Medicine & Science in Sports & Exercise study. When people played a brain-draining computer game before exercising, they reported a subsequent workout as being harder, yet their muscles showed the same activity as they did doing the same workout after an easy mental game. So if you think you can’t eke out those last 10 minutes on the rowing machine, remember: You can! [Tweet this motivation!]
For girls and adult women, educational interventions are considered a powerful means of improving their health and nutritional status throughout their lives. Education level is often associated with maternal caregiving practices and the nutritional outcomes of their children (174, 175). Few studies, however, evaluated the impact of education as an intervention on women's nutrition outcomes. Instead, many studies used survey data and reported on associations between education and nutrition. For instance, in low- and middle-income countries, higher levels of education were associated with lower prevalence of underweight and higher prevalence of overweight among women (176, 177). However, this depended on the type of employment in which women participated (178, 179). In addition, in many high-income settings, the converse was true (177). Level of literacy was also associated with improved anthropometric measures. In southern Ethiopia, literate mothers were 25% less likely to be undernourished than were illiterate women (180). One econometric analysis suggested that doubling primary school attendance in settings with low school attendance was associated with a 20–25% decrease in food insecurity (181). Overall, though, these associations were limited in their ability to draw conclusions about causality and the effect of education interventions on nutrition outcomes.
