Why does muscle drop when I diet?
When you eat less, your body draws on muscle as well as fat. Lifting tells the body to hold on to it, and protein gives it the material.
What does that look like in practice?
Lift three times a week, hit your protein range every day, and keep the calorie cut moderate. A crash diet costs muscle even with high protein.
How do I know it is working?
Your strength holds or rises while your waist shrinks. A DEXA scan gives the cleanest picture. See DEXA and Cronometer.
