I tried this a long time ago. Its just easier to fast, and you get way more mental energy during a fast in my opinion.
Usually I just eat carbs on lift days and eat ketogenically on off days. Your muscles are more sensative to insulin, so you end up getting the best of both worlds.
Also OMAD.
I agree, I love fasting and definitely feel a clearer mind when I do so! That's a great strategy, I tried something similar called Carb Backloading. What does OMAD mean?
One meal a day. The variation I do, I usually only eat one meal, except on lift days where I eat carbs and protein half hour before and right after the lift, usually followed by the rest of my food when I get home. I haven't done it long enough to swear by it, but I have done OMAD and 5-8 hour eating windows for about a year and have seen results. Look up research on fasting in general.
Side Bar:
There have been studies done on patients who have fasted for 3 days prior to kemotherapy exhibited far less negative side effects than a non fasting control group.
