My Patient Started Eating More Protein But Wasn’t Losing Weight. She Was Surprised When This 1 Particular Kind Made A Difference.
A physician-researcher recounts treating a 58-year-old patient who followed the latest protein-heavy advice, including new federal dietary guidelines aimed at women over 40, without losing any weight despite months of Greek yogurt, chicken, shakes, and lifting twice weekly.
The doctor found the patient's protein intake was already generous but almost entirely animal-sourced, with little from beans, lentils, soy, or whole grains. Citing the team's own randomized trial in postmenopausal women, plus a 130,000-person cohort study and a separate meta-analysis, the piece argues that shifting protein source toward plants, not just adding more protein, drove reductions in hot flashes and modest incidental weight loss.
The patient was then advised to swap ground beef for lentils, dairy for tofu, and protein bars for lentil soup, reorienting her grocery list rather than her calorie count.
