greetings & salutations this variation-on-a-theme is brought to you by the letters I and F
so i can do a 16:8 daily fasting window just fine, i can even do 18-20 fasted. my question regards types and durations of training and fasting/non-fasting.
for a 45-60 minute strength training with limited metcon (or if it's primarily metcon), im pretty sure fasted is the way to go. but what if someone is doing more skill based training, such as gymnastics, circus arts, capoeira, etc? does skill based training benefit from non-fasted training? the training in question is also 90 minutes in duration.
what about training twice per day? if the skill training is in the morning, and the strength training is 6+ hours later? what about vice versa?

I'll probably add more to this answer tomorrow, but I don't think skill based training would benefit from being fasted nearly the same way that endurance or strength training would.
As to the 2/day question, skill training in the morning and strength training in the afternoon probably works best when you consider the daily patterns of testosterone and cortisol,
but fasted strength training would probably give you great adaptations and so doing it in the morning would probably be most feasible

This is something I've been experimenting with lately so I'll give you some of my observations. Some personal background:
- Follow the 16:8 approach (for approximately 8 weeks)
- Strict paleo diet
- 24 hour fast every 1-2 weeks.
- Coffee(usually Bulletproof or containing cocounut oil) in the AM.
- Consume 10g BCAA preworkout.
- Try to workout fasted 100% of the time as part of the experiment.
- Typically high fat/mod protein/low carb
Here are my observations and data from my most recent lower body workout. I began the workout @ 4 PM It consisted of the following exercises:
- Squats (1x10, 3x5)
- Deadlift (4x5)
- Glute-Ham Raise (3x max-rep, neg to failure)
- Barbell Hip Thrust (3x10)
- Calf Raise (3x12, 3x12, 3x12) multiple toe angle superset
- Seated Calf Raise (3x12)
I "felt" noticeable stronger in my heavy lifts compared to the previous sessions. Not sure how much has to do with adaptions since last sessions, but I didn't feel weaker with no "gas in the tank". No ill effects were noticed. I also haven't noticed any ill effects during HIIT or LISS. I have retained and gained muscle mass during the protocol. Fat loss (especially the stubborn areas) has increased. I'm still gathering all the data for a blog post on IF coming up soon. I haven't done any of the metabolically challenging stuff in the mornings due to my fears of elevated Cortisol in the morning.
Hope this helps! Best thing to do is some self experimentation and record results!
