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!]

Third, of the interventions that were evaluated, many interventions targeted women who were pregnant, lactating, or with young children <5 y of age. We do not refute the important focus on mothers and their children as a group deserving of special attention, given women's increased nutrient needs during pregnancy and lactation and the intergenerational consequences during this period. However, even the interventions that focused on maternal nutrition often only reported on birth and nutrition outcomes of the child, and not those of the mother. In addition, although there were interventions that targeted adolescent girls and women of reproductive age, they were fewer and less well evaluated than interventions that targeted women as mothers. This aligns with findings from other research which illustrated a higher proportion of programs targeting pregnant and lactating women and women with young children (209). We also found major gaps in the targeting of interventions for older women. With growing rates of overweight, obesity, and noncommunicable diseases, in addition to undernutrition and micronutrient deficiencies, it is essential to think outside of the maternal-focused paradigm to reach women at all life stages.
Many nutrition-sensitive approaches were delivered in broader community-based settings and more equitably reached women across the life course. Non-facilities-based settings more equitably delivered nutrition interventions to women who were not pregnant or lactating, and who were less engaged with health clinics and schools. For instance, food fortification, which was often delivered through markets, home visits, and community centers, seemed to be more effective at reaching women of reproductive age than health center–based delivery platforms. Community-level interventions are often reported as more equitable than platforms that require access to “fixed and well-equipped health facilities” (212). This aligns with our findings, where we found that community-based platforms such as home visits, community centers, homes of community leaders, work, mass media, mobile phones, and commercial settings were effective at reaching women across the life course (Table 1). Other delivery platforms such as marketplaces, water points, tailoring shops, and agricultural points for seeds or inputs were also effective. These locations need to be context-specific in order to capture where women spend their time. For instance, in countries where many adolescent girls do not attend school, school-based delivery platforms might be less effective. Delivery platforms also need to be sensitive to the sociodemographic differences that influence where women spend their time, such as differences for women in rural and urban areas, and of different socioeconomic statuses. Additional research needs to identify and report where women and adolescent girls are, and how best to reach them.

Many women and teenage girls don't get enough calcium. Calcium-rich foods are critical to healthy bones and can help you avoid osteoporosis, a bone-weakening disease. Additionally, recent studies suggest that consuming calcium-rich foods as part of a healthy diet may aid weight loss in obese women while minimizing bone turnover. The National Institute of Medicine recommends the following calcium intake, for different ages:

Nutrition-sensitive approaches are difficult to link to women's nutritional status (5, 102). This is due to limited measurement of benefits to program beneficiaries, families, households, and communities, limited timeframes to evaluate long-term impact, logistical and political realities that make implementation difficult, and different priorities of different stakeholders in multisectoral programs (102). Many nutrition-sensitive approaches, as will be described, thus focus on more distal measures of impact (e.g., coverage, knowledge) and not more proximal measures of women's nutritional status (e.g., BMI, anemia status, etc.).
