WAY too many search results came up, so I'm starting a thread on this for me, hope you don't mind!
Two years ago I was explaining how cavemen would eat meat in the winter and then wait until spring and summer and gorge on meat and all the fresh produce, and then winter would come and they'd just stick with meat (and rare seasonal fruit/veggies).
Funny how I didn't think of that since being paleo on/off the past year. Is this what people mean when they say they are eating seasonally?
If so, would this be optimal for 1.) weight loss and 2.) killing yeast (associated with alcohol that's been cut down to 1x a wk).
