The clients who struggle most with fasting are not the ones who can't get through the fast. They usually manage that fine after the first week or two. The ones who fall apart are the ones who get to their eating window with nothing ready and then just eat whatever is closest. Hunger plus zero prep is a reliable way to blow the whole point of what you spent the day doing.

Meal prep is something I push hard with people doing OMAD or 18:6 because the window is short and there is no margin for standing in the kitchen figuring it out when you are already past hungry. Having one solid meal ready to go changes the behavior completely, not because it is magic, but because it removes the moment where bad decisions get made.

What I'm less sure about is how much prep is actually necessary versus how much is just comfort. Some people do fine with a loose plan and real food that takes ten minutes. Others need everything portioned and labeled or it falls apart.

Curious what people here have found over time. Does having the meal ready in advance actually move the needle for you, or is that just a personal training thing that does not translate outside that context.

Something I started doing with a few clients that has been more useful than expected is running a simple spreadsheet on what they eat in their eating window, not to count every macro obsessively, but just to see the pattern after a few weeks. Most people doing OMAD or 18:6 have no real picture of what they are actually eating when that window opens. And what shows up in the data is almost always the same thing. They are under on protein and way over on whatever they were craving all day

The fasting part works. That part is not really the problem for most people once they get past week two. The meal itself is where things go sideways. One big plate does not automatically mean balanced. And when you are that hungry, the tendency is to eat fast and stop tracking mentally before the meal is even over

What helped was logging the meal the day before as a plan, not the day of. It sounds like extra work but it takes maybe four minutes and it removes the decision from a moment when hunger is running the show.

Anyone else found that the eating window is where most of the actual effort lives once the fasting habit is locked in? The fasting itself becomes background noise pretty fast for most people

Been training clients for a while now and the question that comes up most is how to fit fasting around workouts without tanking performance. I run myself so I have a personal stake in this too.

What I've found works better than most people expect is OMAD or a solid 18:6 window built around the training block. Eat after the session, not before. Most people overthink the preworkout meal and it ends up being anxiety eating more than anything functional.

The harder part is getting clients to trust the process when they feel flat in the first week or two. That adaptation period is real and it throws people off. They assume something is wrong when really the body is just recalibrating.

Where I still have questions is resistance training specifically. Endurance work during a fast feels manageable. Heavier lifting sessions are where I notice the most pushback from people, and honestly from my own body on longer fasts.

Curious what people here have landed on, especially if you're pairing fasting with any kind of consistent training load. Not looking for bro science, just real patterns people have noticed over months of doing it.
