The only scientifically PROVEN fact about why IF works is calorie deficit. It helps control calories. Nothing more, nothing less.
I find it helps with energy levels too, but that is merely a widely reported anecdotal experience with scientific theory to back it up. In the same respect, i've seen quite a few similar studies that say the same thing about eating a big breakfast. Which has just as much validity. So you need to be objective.
But being objective doesn't include ignoring the articles that don't fit your argument and waving around the ones that do.
I've been IF'ing for about 2 years now. Done it for so long because i just got used to eating that way. Used it for both cutting and bulking. In the past week i have gone back to eating 'normally'. To be honest IF made fvck all difference whatever my goals were.
I have come to my own conclusion that you can eat whenever and whatever you want as long as it matches what your daily kcals and macros are, fvcking around with timings and sh1t really doesnt matter.
Eat healthy, lift weights, live healthy, have fun and treat yourself now and again is the best 'lifestyle' and 'diet' you can do.
Lyle McDonald really has quite a background though, being a former collaborator of the great Dan Duchaine. Years ago, before he started writing books, he trialled Duchaine's BodyOpus program and wrote a very detailed journal of his experiences. He proved himself very scientifically adept and apparently even Duchaine conceded that Lyle understood his BodyOpus better than he did himself.
It really is a shame that he has become so bitter and twisted.
unfortunately too many people want a magic pill, 'super foods' or secret formula to convince them that they are being 100% committed or hardcore.
People spend more effort on convincing themselves that meal timing, keto or chicken n sweet potatoes or IF is the 'final missing piece of the puzzle" rather than reading up from an objective point of view and realizing it matters very little
In my humble opinion one of the most common errors (at least to my mind) which many on here make is that they follow diets which are so damn bland that it's unbelievable. Apart from the sheer monotony, I'm sure that the lack of variety also leads to a lack of complete nutrition from micronutrients.
I realise that time is a constraint for most of us which may limit choices for the first few meals of the day until we're home from work. But at least once a day it's worth spending slightly longer in the kitchen to actually make something worth eating. So many nice great things to eat which are fully compatible with our bodybuilder diets.
Learney was subtly referring to that in this article: http://www.phillearney.com/nutrition...-a-discussion/
Fasting and Intermittent fasting as a dietary method has been something we’ve seen an awful lot about as of late and if I’m honest some great data and studies to support it. Shame that the one site I’ve seen heavily promoting it as a method uses a LOT of VERY indirect studies that have a loose association with the subject. Infact I read a few of the references and they where downright bad for what was trying to be validated tbh. But anyways
Think Alan Aragons articles are very good though, doesn't take things to extremes..
I used to read and post to misc.fitness.weights in the 90s, when I first heard about Lyle. Now true enough, he doesn't suffer fools, and maybe batters home his point, but I've not known him pursue an argument with fervour and be wrong.
And I struggle HUGELY with the concept that you beat him intellectually.
