You won't know you're losing bone density until something breaks.
This isn't just an age thing. Sitting all day, crash dieting, smoking, drinking heavy, or being on a GLP-1 can all be quietly costing you bone density right now — no matter how old you are.
Here's what's actually happening and the 3 things that make the biggest difference:
1️⃣ Lift heavy — resistance training is the strongest signal you can send your bones to stay dense. Cardio alone won't cut it.
2️⃣ Get your protein, calcium, and vitamin D in. Calcium needs go up with age — women at 51, men at 71. Don't guess on vitamin D, get it tested.
3️⃣ Don't crash diet. Rapid weight loss without resistance training — from an extreme deficit or a GLP-1 — takes muscle and bone with it.
