Dr. Betty Murray explains why fat loss matters more than weight loss. Losing muscle contributes to sarcopenia, which tanks your metabolic rate, bone density, strength, and mobility. Preserving lean mass isn't about looks—it's about staying independent as you age.
Weight loss is different than fat loss, and it's different than lean body mass. What does the research actually show about lean body mass? Because again, this is what I was pissed off about. Weight loss is different than fat loss, and it's different than lean body mass, right? What we want is fat loss. Overall weight loss isn't awesome if I'm losing muscle mass. You're already at risk of what they call sarcopenia— lean muscle mass loss, muscle loss due to just loss of hormones and aging. Preserving lean mass is not just cosmetic to look good in a shirt, sleeveless shirt. It is so, so very important about your metabolic rate, your bone density, your strength, and your ability to move and your freedom later on in life.
