Women‘s Protein Needs Significantly Underestimated, New Research Suggests
WASHINGTON D.C. - December 2, 2025, 05:18:16 EST – A growing body of scientific evidence indicates women are routinely consuming insufficient protein, potentially impacting their health across all life stages, from reproductive years through menopause and beyond.While general protein recommendations exist, emerging research highlights unique physiological needs in women that necessitate a reevaluation of current dietary guidelines. This shortfall can contribute to muscle loss, weakened bone density, hormonal imbalances, and diminished overall well-being.
Traditionally, protein intake recommendations have been based largely on studies conducted on men. Though, women experience distinct hormonal fluctuations, metabolic differences, and physiological demands – particularly during pregnancy, lactation, and the menopausal transition – that increase their protein requirements. Experts now suggest that many women may benefit from significantly increasing their daily protein consumption to optimize health and prevent age-related decline. The implications are considerable, affecting an estimated 3.5 billion women globally and prompting calls for updated nutritional advice and increased awareness.
Protein is essential for numerous bodily functions, serving as the building block for tissues, enzymes, hormones, and antibodies. For women, adequate protein intake is crucial for maintaining lean muscle mass, which declines with age and impacts metabolism. Studies demonstrate a direct correlation between higher protein consumption and improved bone health, reducing the risk of osteoporosis, a condition disproportionately affecting women. Furthermore, protein plays a vital role in regulating appetite and supporting hormonal balance, particularly during periods of significant physiological change.
Current dietary recommendations suggest a minimum of 0.8 grams of protein per kilogram of body weight. However, recent research indicates that women, especially those who are physically active, pregnant, breastfeeding, or experiencing menopause, may require up to 1.2-1.7 grams per kilogram. For a 68kg (150lb) woman, this translates to a daily protein intake ranging from 82 to 116 grams.
Sources of high-quality protein include lean meats, poultry, fish, eggs, dairy products, legumes, and plant-based protein sources like tofu and quinoa. nutritionists recommend distributing protein intake evenly throughout the day, rather than concentrating it in a single meal, to maximize absorption and utilization. Prioritizing protein-rich foods is a proactive step women can take to safeguard their health and enhance their quality of life.
