I'm 46 years old and I've been doing a half hour of aerobic and a half hour of lifting 5 times a week for 13 months. My diet is mostly 1/3 protein bar and coffee in the morning, Subway turkey double meat with half the bun and lots of veggies for lunch and chicken, rice a little hommus for dinner. I probably add an apple in the afternoon and a couple of small snacks at night. Any ideas what I should be adding? I do take a multi-vitamin every day. Thanks!
