Fasting before beginning Paleo?

I'll be committing to Paleo for at least the next couple of months and a friend of mine is telling me to fast for 24 hours beforehand to give my digestive system a rest, then slowly ease into Paleo with "light" foods like eggs, etc. Is there are any benefits to this approach?

Thanks. :)

Just say no. Seriously gradually switch to paleo. If you do it over the course of 2-3 weeks you will have no issue adjusting. If you do not, you're much more likely to suffer serious digestive upset.

Ketogenic is not a necessity either. I'd advise strongly against dipping carbs too low at least initially.

I don't see a pro or a con in this approach. I really don't think it will matter either way. HOWEVER, good luck fasting before you are fat adapted! I couldn't go two hours without eating pre-paleo because I was a sugar burner. I would have died if I went a whole day! It wasn't until I became fat adapted I can handle fasting.

Fasting before introducing/reintroducing a food is the perfect way to assess how your body responds to it IMO. I'm only talking about a 12-24 hour fast maximum, beyond 24-36 hours there's every chance that a food you would usually find very tolerable will go straight through you!

I'm not a fan of the shock and abruptly change everything, then maybe fall back on old habits, approach. 24hr fasts / paleo diets are useful tools, but you might want to build up some experience with them first before diving head first into the deep end. I can think of a few things that can go wrong with the sudden transition and no benefits above doing that once it's comfortable to do so. (I'm thinking electrolytes get out of whack, dehydration sets in, blood sugar freaks out, insulin sensitivity drops, brain fog, heart palpitations, gut / digestive issues, hunger / discomfort, adrenals ramp up, etc.) Once you've figured out the diet and you've pulled off eliminating snacking, then skipping a meal or so every day, then, occasionally bump it up to two for fun. I tend to look at eggs as a fairly rich food myself.
