If you do decide to diet, you still need to maintain good nutrition. You want to cut back on calories, not nutrients. And while you want to reduce fat, don't eliminate it entirely. Some studies suggest that older women who maintain a higher body-fat percentage are less likely to suffer from osteoporosis and other conditions associated with menopause. Fat cells also retain estrogen, which helps maintain the calcium in your bones. Younger women should be careful, too: a low body fat percentage can lead to infertility; below 17 percent may lead to missed periods, also known as amenorrhea.
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.
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).
A well-balanced diet, comprised of a variety of foods, adequately meets women’s needs for vitamins, minerals and energy. For good health, women need to pay special attention to calcium, iron and folate (folic acid) intake. A healthy diet also should minimize the intake of fat and sugar. Diets high in saturated or trans fat can promote high levels of blood cholesterol and increase risk for heart disease. A diet that includes high sugar provides empty calories, or calories that do not provide any nutritional value and often times replace more nutritious food selections.
There were also supplementation programs that targeted nonpregnant women. National supplementation programs that provided food baskets to low-income families increased maternal BMI and improved household food insecurity (92, 93). However, there were some unintended consequences. In Mexico, food transfer programs disproportionately increased weight gain in overweight women compared with underweight women (93), and 1 study in Bangladesh found that food transfers had larger impacts on men's intake than women's intake, except with less preferred foods (94). Adolescents who received protein-energy supplementation at school showed an increase in weight gain during supplementation, as well as improvements in school attendance and mathematics scores (46, 95). However, the impact of supplementation on micronutrient deficiencies and, specifically, hemoglobin concentration, was limited (46).
If motivation is your hang-up, change your exercise routine every 14 days. A University of Florida study discovered that people who modified their workouts twice a month were more likely than to stick to their plans compared to those who changed their regimens whenever they wanted to. Boredom didn’t appear to be a factor; it seems people simply enjoyed the variety more.
