Bear Grylls has switched from Vegan to an 'Ancient' diet eating mostly meat - offal so it's not so expensive - and just a little rice or potato. Not quite as dramatic as your friend but he says he feels much better for the switch.
I can't imagine following such a diet. It feels wrong on so many levels, and goes against all the advice I have heard all my life. 'Fraid I'll listen to Chris Packham rather than Bear Grylls on this and keep meat for just an occasional meal.
Butterflies, I've never seen this one before
Branston’s pickle, Colman’s mustard and Bisto gravy ..
