First some context: my primary interest is healthy aging, not to be a competitive power lifter. My lifts are ‘decent’ (aka insectoid). I lost some bellyflop, gained some strength and still enjoy riding my race bike and the occasional (kick)boxing session.
I’m getting a lot of conflicting information on this topic, some people say its no good for nothing at all, but: https://www.youtube.com/watch?v=iywhaz5z0qs tells a different story. Same goes for many aspects of nutrition. What I would really, really, reallllyyy, REALLY love is for you and Rhonda to do an extensive podcast on nutrition from both your sides of view. She has strong opinions on healthy micronutrients, that might differ from yours (she’s a biochemist, not an MD).
Perhaps if you join forces we can distill some usable information for us sporty types…
As of this writing, I don’t think a focus on micronutrients or fasting greater than the standard between meal times is useful for improving longevity or health outcomes otherwise unless it produces a calorie deficit (if someone is overweight) or changes something else about the person.
Apologies for bumping an old post but having searched for posts on the topic I wanted to address it seemed to make more sense than starting a new one.
I have two questions but I guess I should also ask, firstly whether your thinking has changed in respect of the OP’s original question given a year or so has passed since ‘as of this writing’?!
My questions are:
There appears to be a lot of research backing caloric restriction/various types of fasting diet and IF as having benefits for general health and longevity. In addition a lot of seemingly ‘credible’ people back that horse (Rhonda Patrick being one, who has been mentioned a few times on this forum, but I am not sure you are that familiar with her work based on your responses in the relevant threads). So my question is whether you feel you have read all or an extensive amount of the relevant research and subsequently concluded that the evidence does not back up the purported benefits or whether it is something that you have not looked at in much detail and it’s simply a case that you haven’t come across any evidence without having focussed on the topic?
And by extension, if the answer is the former, have you looked into other interpretations of the evidence(by erm 'credible people!) and found that you disagree with them or it’s more the case that you have formed your own conclusions from the research and have not looked into other responses?
All other things being equal do you think an IF diet (say restricting eating to ~8 hours) has any negative effects on gains/retention of muscle and strength? Particularly when cutting but also at bulking/maintenance? My main concern is lack of protein over that period of time although there seems to be some research around protein pulse feeding that maybe counteracts that…
The reason for my first questions is that I find it disconcerting when people you feel are credible in a certain area come up with different conclusions from the same research, particularly if they have had a chance to examine the arguments that oppose their own view. It’s much easier when all the ‘credible’ people line up on one side and less credible people on the other!
Thanks (and apologies for repeated use of the word credible!).
