So I went primal last year and lost 35 pounds and felt awesome and great and all that.

But this year I let myself go and ate donuts and raviolis etc. Needless to say, I've gained the weight back.

So I keep restarting my primal diet/lifestyle and then stalling, and restarting and stalling, and I kid you not.... I plucked like 5 beard hairs that were alternating patterns of brown white. Like a frickin zebra.

The natural conclusion: Hair going white/grey is totally affected by diet. Going grey, eat primal!
