Meal and Training timings

Fasted Training

calculated Note: Training can be performed anytime within the above time frame.

First meal

 

Second meal

 

Third/Last meal

 

Pre-workout meal

 

Training

  Note: Training should happen within 3 hrs from conusming the pre-workout meal.

Post-workout meal

calculated Note: This meal should be consumed within 1 hr from training completion.

Pre-workout meal

calculated

Training

calculated Note: Training should happen within 3 hrs from conusming the pre-workout meal.

Second/Last Meal

  Note: This meal should be consumed with a gap of 8 hrs from the Post-workout meal. As this will end the 8 hr feeding window. Note: This meal should be consumed with a gap of 10 hrs from the Post-workout meal. As this will end the 10 hr feeding window.
For Instance: If your "Fasted Training" started at 01:00 pm and ended at 02:00 pm then your "Post-workout meal" consumption should start precisely at 03:00 pm.
Note: Technically this "2 meals/day with 1 pre-workout meal" configuration won't come under 14/10 hrs fast/feed. As there are only 2 meals a day, one will become pre-workout meal and another will become post workout meal. As Pre-workout meal should be eaten 3 hrs before Training and post-workout meal within 1 hr after training completion, this shrinks the 10 hr feeding window to a 4 hr window. So this setup will become a 20/4 hrs fast/feed. If you want a strict 14/10 hrs fast/feed please go for either a 2 meal configuration(No. of Pre-workout meals=None) or any of the 3 meal configurations.
For Instance: If your "Fasted Training" started at 01:00 pm and ended at 02:00 pm then your "Post-workout meal" consumption should start precisely at 03:00 pm, with this meal your 10 hr feeding window opens. So your "Second/Last meal" should end at 1:00 am, with this meal your 10 hr feeding window ends and your fasting phase begins.
For Instance: If your "Fasted Training" started at 01:00 pm and ended at 02:00 pm then your "Post-workout meal" consumption should start precisely at 03:00 pm, with this meal your 8 hr feeding window opens. So your "Second/Last meal" should end at 11:00 pm, with this meal your 8 hr feeding window ends and your fasting phase begins.
Note: Technically this "one meal" configuration won't come under 16/8 hrs fast/feed, as there is only one meal a day this setup will essentially become a 23/1 hrs fast/feed. If you want a strict 16/8 hrs fast/feed please go for either a 2 meal configuration(No. of Pre-workout meals=None) or any of the 3 meal configurations.

Note: Technically this "2 meals/day with both as pre-workout meals" configuration won't come under 16/8 hrs fast/feed. As there are only 2 meals a day, and both becoming pre-workout meals, one should be eaten 7 hrs before training and the other should be eaten 3 hrs before training. This shrinks the 8 hr feeding window to a 4 hr window. So this setup will essentially become a 20/4 hrs fast/feed.
