Adopting a plant-based diet could help tip the scales in your favor. A five-year study of 71,751 adults published in the Journal of the Academy of Nutrition and Dietetics found that vegetarians tend to be slimmer than meat-eaters even though both groups eat about the same number of calories daily. Researchers say it may be because carnivores consume more fatty acids and fewer weight-loss promoting nutrients, like fiber, than herbivores do. Go green to find out if it works for you.
It's easy to get lost in a killer playlist or Friends rerun on the TV attached to the elliptical, but mindless exercise makes all your hard work forgettable—and you can forget about seeing results too. “There is a huge difference between going through the motions of an exercise and truly thinking, feeling, and engaging the key muscles,” says Kira Stokes, master instructor at the New York City location of indoor cycling studio Revolve. “Be conscious of and enjoy the sensation of your muscles contracting and the feelings of growing stronger and more powerful with each rep.”
Social protection interventions are intended to support vulnerable households by providing them with in-kind (e.g., food) or cash transfers. The impact of social protection on women's nutrition was nuanced, as such interventions were associated with protecting against adverse nutrition outcomes, but were also associated with excess weight gain in some settings. In-kind transfers, including food baskets, fortified foods, and school lunches, improved women's and adolescent girls’ energy and micronutrient intakes, as described in the preceding sections. Both CCTs and unconditional cash transfers were common around the world and were associated with improvements in health care utilization and increased food expenditures (5, 14, 195, 196). CCTs were dependent on “conditions” such as school attendance and health care utilization. For children in Burkina Faso, CCTs were associated with greater numbers of preventative health visits compared with unconditional cash transfers (197), and this could be relevant to adult women's health care utilization as well. Unconditional cash transfers, such as old-age pensions, were also common, including in low- and middle-income countries (5, 198). Older women who received pensions had fewer missed meals (199), although evidence was mixed (200). In South Africa, granddaughters who cohabitated with women who received pensions had improved anthropometric measures and fewer missed meals, indicating spillover effects of pension transfers (199, 201).
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.
For this comprehensive narrative review, we evaluated both nutrition-specific and nutrition-sensitive interventions. Nutrition-specific approaches are those that address the immediate determinants of nutrition (e.g., food and nutrient intake, diet-related practices and behaviors, disease, etc.), whereas nutrition-sensitive approaches are those that address the underlying determinants of nutrition (e.g., food security, access to resources, safe and hygienic environments, adequate health services, etc.) (5, 12). We evaluated the following nutrition-specific interventions described by Bhutta et al. (13, 14): nutrition counseling and education, micronutrient supplementation and fortification, protein and energy supplementation, and lipid-based supplementation. We also included the following nutrition-sensitive approaches described by Ruel and Alderman (5) and Bhutta et al. (14): health care; family planning; water, sanitation, and hygiene (WASH); empowerment; income-generation; education; and social protection. For each intervention, we 1) described the scale and coverage of the intervention, when available; 2) summarized the evidence of effectiveness for women's health and nutrition outcomes; and 3) described and evaluated the target population and delivery platforms, as described in the published articles and as summarized in Table 1. The delivery of interventions included the physical platforms, as well as the adherence and the implementation challenges of the different interventions.
Vitamin D: Over the past decade, dozens of studies have revealed many important roles for vitamin D, the nutrient that skin cells produce when they are exposed to sunlight. The recommended daily intake of Vitamin D is 600 IU per day, although recommended levels are under review. If you avoid the sun or live in the northern half of the U.S., ask your doctor whether your vitamin D level should be tested.
Adult women, and particularly women with children, were the primary targets for empowerment interventions. Empowerment interventions were predominantly delivered through community-based programs, including home visits, community groups, and community centers (5, 161, 163). There was some evidence that empowerment interventions that included delivery platforms such as radio and television, as a complement to the community- and home-based delivery platforms (5), could have some impact on reaching a wider audience. Adolescent girls were largely not the target of empowerment interventions, except for those relating to reproductive health (158), and could potentially benefit from them.
The new guidelines encourage eating more nutrient-dense food and beverages. Many of us consume too many calories from solid fats, added sugar and refined grains. The guidelines promote a diet that emphasizes vegetables, fruits, whole grains, fat-free or low-fat dairy products, seafood, lean meat and poultry, eggs, beans and peas, and nuts and seeds.
Women and men differ in their chromosomal makeup, protein gene products, genomic imprinting, gene expression, signaling pathways, and hormonal environment. All of these necessitate caution in extrapolating information derived from biomarkers from one sex to the other. Women are particularly vulnerable at the two extremes of life. Young women and adolescents are at risk from STIs, pregnancy and unsafe abortion, while older women often have few resources and are disadvantaged with respect to men, and also are at risk of dementia and abuse, and generally poor health.
Most vegetarians eat milk products and eggs, and as a group, these lacto-ovo-vegetarians enjoy good health. A healthful vegetarian diet falls within the food pyramid guidelines offered by the USDA. However, meat, fish and poultry are major sources of iron, zinc and B vitamins, so pay special attention to these nutrients. Vegans (those who eat only plant-based food) should consult a health care professional about adding vitamin and mineral supplements; make sure you consume sufficient quantities of protein, vitamin B12, vitamin D and calcium.
Here, too, body size is the main difference between the needs of males and females. Despite all the hype about high-protein diets, our protein requirements are really quite modest — only about a third of a gram per pound of body weight. For a 125-pound woman, that amounts to about 42 grams, for a 175-pound man, 58 grams. That's a tiny difference, just about half an ounce a day.
Popular belief says if you really want to make a big change, focus on one new healthy habit at a time. But Stanford University School of Medicine researchers say working on your diet and fitness simultaneously may put the odds of reaching both goals more in your favor. They followed four groups of people: The first zoned in on their diets before adding exercise months later, the second did the opposite, the third focused on both at once, and the last made no changes. Those who doubled up were most likely to work out 150 minutes a week and get up to nine servings of fruits and veggies daily while keeping their calories from saturated fat at 10 percent or less of their total intake.
Systematically report and evaluate women's nutrition outcomes in research and program evaluation documents in low- and middle-income countries, including outcomes for adolescents, older women, and mothers (as opposed to reporting on women's nutrition as child nutrition outcomes alone). When possible, report and evaluate differences by setting (e.g., rural compared with urban) and socioeconomic status.
