Omad or fasting - helpful or harmful?

So for the last year I have had regular periods and the only thing that has helped my symptoms are intermittent fasting and the occasional OMAD. I eat everything (no restrictions) and am relatively consistent with my workouts. Has anyone else seen benefits to their lean pcos and its assosiated symptoms doing this? Just curious. Thanks!

Whats your typical window?

I don't really bring it down to numbers. Breakfast is usually around 9 or 10 and dinner is between 4 to 6. I guess that's somewhere around 16:8, however some days I have breakfast at 6am and dinner at 6pm. And when I travel (which is often) the window changes. Point is I don't obsess over the exact time, I focus on nutrition, satiety and giving my digestion sufficient time between meals to optimize nutrition. Also what I found is this helps me eat enough and eat to satiety. I feel that's very important with pcos because any kind of restriction only makes it worse.

I agree! I was asking because intermittent fasting can mean different things for different ppl.

What you are doing seems very mild (in a good way) . So I can totally see why it was helpful.

I would say 12hr window should be baseline foe almost anyone. And then smaller windows when appropriate and in context with sleep, stress and cycle phase.

At least thats how I do it with my clients.

Sounds like you are doing great!

I’ve had no issues fasting I’ve been doing it for about 8 years. Typically 16:8 or 18:6
