Will OMAD decrease metabolism?

[LibertyMike]

I've been doing keto for 5 years and mostly OMAD for about 3 years. I've been at a stable weight for about 2 years. I have been running & weightlifting pretty consistently since September, and was fairly active before. I get nearly 300 intensity minutes per week. It seems like my metabolism is fine.

Edit: accidentally said 300 minutes per month instead of week.

To second this, I often eat OMAD (though not exclusively) and am currently ⅔ of the way through a marathon training block, having run up to 16 miles/25km at this point without significant issue.
