One of the most consistent gaps I see in nutritional evaluations for women over 45 is not total caloric intake. It is protein quality and when it is eaten.
Research continues to confirm what the clinical evidence has suggested for years: the muscle protein synthesis response to dietary protein becomes blunted with age. After 45, the body requires a higher leucine threshold to trigger the same anabolic response a lower dose would have produced at 30.
Two things follow from this. First, the quality of the protein source matters. Complete proteins with full essential amino acid profiles, including animal proteins, eggs, and specific plant combinations, trigger a stronger response than incomplete sources. Second, distribution matters as much as total intake. Concentrating protein in one or two meals is consistently less effective for lean mass preservation than spreading intake across multiple meals with a complete protein at each sitting.
For women in perimenopause or postmenopause, these are not theoretical concerns. Sarcopenia, the age-related loss of skeletal muscle mass, accelerates when estrogen declines. Muscle loss is not just a body composition issue. It is a metabolic risk factor directly linked to insulin resistance, bone density loss, and reduced functional longevity.
Protein strategy is part of a complete clinical conversation. At The Lamkin Clinic, nutrition protocol is built alongside medical protocol, not separately from it.
