Lipid-based nutrient supplement (LNS) programs are intended to enrich diets with micronutrients and essential fatty acids (97), and are often used in emergency settings to meet nutritional needs of pregnant and lactating women (98). Of the studies that report on women's health outcomes, LNSs provided to pregnant and lactating women increased body weight and midupper arm circumference, particularly of multiparous women and women >25 y of age (99). They were associated with increased plasma α-linoleic acid, although not plasma lipids and other fatty acids (100). LNSs did not affect women's immune responses, particularly pregnant women's anti-malarial antibody responses (101). There was limited evidence connecting LNS supplementation to unhealthy weight gain and retention, and this is being explored in ongoing studies in Ghana (97).
A 55-year-old woman who gets less than 30 minutes of daily physical activity should eat five ounces of grains; two cups of vegetables; one and a half cups of fruit; three cups of milk; five ounces of meat and beans; five teaspoons of oils, and no more than 130 calories of additional fat and sugar. If she got 30 to 60 minutes of daily exercise, she could increase her intake to six ounces of grains; two and a half cups of vegetables; and up to 265 additional calories of fat and sugar.
There are many well-documented challenges in disentangling empowerment interventions from other interventions with which they are delivered. Empowerment interventions are often integrated into income-generating activities and agricultural extension, and many empowerment approaches are retroactively classified as “nutrition-sensitive” despite a lack of nutrition components in the original intervention designs (5). In addition, many studies are limited in scope and their evaluation of nutrition outcomes (159), and it is difficult to evaluate which dimensions of women's empowerment matter most for nutrition (162). Notably, indicators to quantify women's empowerment are also not used consistently and vary widely between individual studies (158).
Nutrition education, including communication and counseling to raise awareness and promote nutrition-related knowledge and behaviors aligned with public health goals, was found to increase women's knowledge and improve women's dietary diversity and protein intake (15–21). It also reduced energy intake of overweight women over a 9-mo period (22). However, evidence for the effectiveness of nutrition education interventions showed mixed impact on biological and anthropometric markers of women's nutritional status (14–16, 18, 23–29). This could be due to lack of statistical power given the small sample sizes of the reviewed studies. For adolescent girls, nutrition education was found to reduce odds of overweight, and improve knowledge, dietary intake, physical activity, and sedentary behavior (27, 29, 30). This was particularly true for nutrition education that lasted longer than 12 mo (29). Nutrition education was also more strongly associated with changes in health outcomes in studies evaluating childhood obesity treatment, rather than childhood obesity prevention (29).
Both your nutritional needs (the food and water) and your metabolism (how fast your body converts food to energy) change at this age. Your metabolism gets slower. Women lose about half a pound of muscle per year starting around the age of 40. That makes losing weight even more difficult. Some of the changes women experience are due to decreased hormones, reduced activity level, and medical conditions.
Trimming some fat may eliminate some guilt, but be warned: Buying foods labeled “low-fat,” “non-fat,” or “fat-free” may encourage you to eat up to 50 percent more calories, according to three studies by Cornell University’s Food and Brand Lab. Fat’s not the issue when it comes your weight since most of these foods only have about 15 percent fewer calories than their regular counterparts. Go for the full-fat version and eat less—you probably will naturally since they taste better.

Calcium: For adult women aged 19-50, the USDA recommended daily allowance is 1,000 mg/day. For women over 50, the recommended daily allowance is 1,200 mg/day. Good sources of calcium include dairy products, leafy green vegetables, certain fish, grains, tofu, cabbage, and summer squash. Your body cannot take in more than 500 mg at any one time and there’s no benefit to exceeding the recommended daily amount.

What you eat is even more important as you enter your 40s. Women need protein (meat, fish, dairy, beans, and nuts), carbohydrates (whole grains), fats (healthy oils), vitamins, minerals, and water. These foods have been linked to some disease prevention, such as osteoporosis, high blood pressure, heart disease, diabetes, and certain cancers. The American Academy of Family Physicians supports the development of healthy food supply chains in supplemental nutrition programs so as to broaden the availability of healthy food.
