About Diet Over Disease

My name is Dr. Gregory A. Villar-Byers, though most people online know me as OldGuyOutside.

After decades working with the U.S. military overseas, I realized that the same discipline, planning, and care we use to protect others should apply to our own wellness. As I grew older, I saw firsthand how much our daily habits shape our long-term health, mobility, and happiness.

I also saw how hard it can be to find clear, trustworthy guidance—especially in a world full of quick fixes, harsh opinions, and conflicting advice.

So I built Diet Over Disease to be different:
a place where adults—especially seniors—can learn, grow, breathe, laugh, and take steps forward at their own pace.
