Is	there	hope	for	nutrition?
	
														With	the	proliferation	of	meaningless	statistico-epidemiologic	studies
and	the	media	flipping	back	and	forth	between	low-carb	and	low-fat,	it	is
increasingly	clear	that	individual	dieters	are	on	their	own.	We	all	have	to	sift
through	the	mass	of	information	and	search	personal	accounts	for	authenticity.
	
														This	book	will	be	a	great	help	for	its	emphasis	on	the	value	of	fasting
rather,	as	is	so	common,	the	warnings	about	the	dangers	of	eating	too	much.
Cristi	describes	the	evolution	of	his	thinking	and	behavior	from	early	religious
practice	to	the	ketogenic	diet	and	the	values	of	the	total-only	water	fast.	The
evolutionary	perspective	and	the	rather	surprising	story	of	fasting	in	the	animal
kingdom	are	well	presented.	The	dental	and	anatomical	evolution	as	well	as
social	influences	puts	this	in	a	broad	perspective.
	
														In	the	end,	the	reader	has	an	insight	to	the	fast,	how	to	get	in	and	how	to
re-feed.	Encouraging	for	most	of	us	is	the	history	of	fasters	in	history	including	a
discussion	of	Upton	Sinclair	who,	like	Cristi,	gave	us	a	blow-by-blow.	Of
current	interest,	of	course,	is	how	we	are	going	to	prevent	and	cure	cancer	and
defy	ageing	with	fasting	and	ketogenesis.	There	is	a	very	good	if	maybe	overly
optimistic	picture	of	the	potential	here	and	the	drift	of	current	as	well	as	details
of	what	to	eat	--	principles	rather	than	recipes.
	
														In	the	end,	this	is	a	remarkably	comprehensive	view	of	fasting.	Cristi	is
clear	that	neither	the	book	nor	the	subject	have	final	answers	but	researchers	and
individual	dieters	have	a	great	place	to	start.
Introduction
Introduction
	
														At	the	time	of	this	writing	(Jan.	2015),	I	was	already	fairly	intimate	with
the	practices	of	periodic	fasting	and	intermittent	fasting.	I	had	been	doing	it	for
more	than	12	months.	This	book	is	not	about	religious	fasting,	though	my
childhood	experience	of	fasting	involves	religious	practices.	It	is	the	starting
point	of	the	book.
	
														From	a	very	young	age	I	was	raised	in	the	Christian-Orthodox	religion.
I	lived	with	my	grandparents	in	a	small	village	in	the	north-western	Romania
until	I	was	5	years	old	and	left	to	attend	kindergarten	in	a	nearby	city.	We	used
to	go	to	church	every	Sunday.
	
														Christian	Orthodoxy	implies	several	religious	fasts	(abstinence	from
certain	foods	or	total	abstinence	from	foodstuff)	throughout	the	year.	The	two
biggest	fasts	are	The	Christmas	Fast	and	The	Easter	Fast.
	
														The	Christmas	Fast	runs	every	year	from	November	15th	until
December	25th,	while	the	Easter	Fast	is	determined	in	a	more	complicated	way,
but	both	of	them	last	approximately	40	days.
	
														Milder	versions	of	fasting	(according	to	Orthodoxy)	imply	not
consuming	animals	or	animal	derived	products	every	Wednesday	and	Friday.
Tougher	versions	require	the	practitioner	to	refrain	from	these	foods	every	day
of	the	fast.	It	is	similar	to	a	vegan	diet.	On	the	extreme	end	of	the	spectrum,	there
are	people	who	abstain	from	food	consumption	for	the	entire	40	days.	They	only
drink	water.
	
														As	a	child	I	found	it	very	hard	to	believe	that	someone	will	not	eat	for
such	a	long	period	of	time.	My	grandparents	were	following	the	usual
"Wednesdays	and	Fridays	No	Animal	Products"	protocol,	so	they	suggested	I	do
the	same,	which	I	did	without	much	discomfort.
	
														My	practice	of	religious	fasting	started	becoming	a	challenge	during	a
Good	Friday	(which	is	also	known	as	the	Black	Friday,	Easter	Friday,	or	Holy
Friday),	the	Friday	before	the	Orthodox	Easter	[1].	My	grandmother	used	to	fast
for	the	entire	day,	until	nightfall.	She	didn't	consume	water	either.	She	prayed
various	times	throughout	the	day.
Description:In a modern world where it's considered normal to consume 3 meals and additional snacks everyday (otherwise you will get sick), fasting can be considered an outrageous and even dangerous practice. One of the biggest fears of fasting is the fear hunger, the false hunger that most people are afraid of
