I subscribed to this in MY early 20's way back in the magazines infancy. Back when the cover photo's were black and white and most of the cover "models" were female athletes. It's changed since then, catering a little more to the "Cosmo" crowd. Which is fine, just not for me. It just doesn't feel like it applies as much to someone in their thirties married with kids as someone in their twenties who apparently has the money and lack of self-control to spend $90 on a designer t-shirt (really). 

A number of health and medical research advocates, such as the Society for Women's Health Research in the United States, support this broader definition, rather than merely issues specific to human female anatomy to include areas where biological sex differences between women and men exist. Women also need health care more and access the health care system more than do men. While part of this is due to their reproductive and sexual health needs, they also have more chronic non-reproductive health issues such as cardiovascular disease, cancer, mental illness, diabetes and osteoporosis.[7] Another important perspective is realising that events across the entire life cycle (or life-course), from in utero to aging effect the growth, development and health of women. The life-course perspective is one of the key strategies of the World Health Organization.[8][9][10]

Although growing bodies need plenty of energy in the form of calories, many children and teenagers consume way too many, says Ruth Frechman, RD, a spokesperson for the American Dietetic Association. The latest findings from federal surveys show that 18% of adolescents and teenagers are fatter than they should be. Kids who are obese are 16 times more likely than healthy weight children to become obese as adults, other findings show.
Fourth and finally, there was a general lack of focus on the relevant delivery platforms for nutrition interventions. Many studies were not explicit about how and where interventions were delivered, and we had to cross-reference multiple sources to identify the delivery platform for many interventions. Delivery platforms are important and relevant information in terms of replicability, but also for identifying who is effectively reached and missed. Information about delivery platforms is also instrumental in understanding gaps in implementation. A greater emphasis on delivery platforms could enhance the reach of nutrition interventions and could also strengthen the capacity to mobilize resources more effectively. For instance, organizing and grouping interventions by delivery platform (e.g., antenatal care, community centers, schools, clinics) or by the relevant stakeholders required for delivery (e.g., ministries, health care providers, teachers, administrators, transporters, etc.) could have the potential to more efficiently deliver nutrition interventions.
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. 
Anaemia is a major global health problem for women.[132] Women are affected more than men, in which up to 30% of women being found to be anaemic and 42% of pregnant women. Anaemia is linked to a number of adverse health outcomes including a poor pregnancy outcome and impaired cognitive function (decreased concentration and attention).[133] The main cause of anaemia is iron deficiency. In United States women iron deficiency anaemia (IDA) affects 37% of pregnant women, but globally the prevalence is as high as 80%. IDA starts in adolescence, from excess menstrual blood loss, compounded by the increased demand for iron in growth and suboptimal dietary intake. In the adult woman, pregnancy leads to further iron depletion.[6]
Family planning and birth spacing can influence the nutrition of adolescent girls, women of reproductive age, and women with young children by reducing the number of adverse outcomes associated with pregnancy and abortion. For adolescent girls, in particular, pregnancy is associated with increased risk of birth complications, anemia, hindered linear growth, and loss of educational attainment (8, 107). Delaying early child marriages and providing access to family planning, particularly for young wives, allow girls to achieve their maximum growth potential (8, 142). However, for women with young children, there was scarce evidence from observational studies to suggest that greater birth spacing had any impact on anthropometric status (BMI, weight), micronutrient status (anemia, as well as serum zinc, copper, magnesium, and folate), and maternal mortality outcomes (13, 107, 143–147). Findings were mixed, which was attributed to sample size and other confounding factors such as maternal age, breastfeeding status, and supplementation status (146, 147). The strongest evidence of the impact of birth spacing on women's nutrition was related to increased risk of preterm delivery and maternal anemia in interpregnancy intervals <6 mo (14, 146, 147) and increased risk of pre-eclampsia in intervals >5 y (107).

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.
