Honey has calories. Remember that. You ideally should be drinking that during the 1 meal time.
But no, it doesn’t “ruin”. OMAD means you eat once a day, and over a week you have eaten 7 meals worth of calories instead of 21 meals.
Are you perhaps thinking of “ketosis?”. Because the sugars in honey would definitely kick you out of ketosis. In which case you messed the ketosis, not the OMAD.
