Wouldn’t it break the fasting window and not technically be OMAD if you ate a separate snack? IF works because of the ratio of eating/fasting. If you break the fast with a snack, you’ve technically started your eating window, right?
In terms of fasting and eating windows, a “meal” is any time you eat. So even an RX Bar and an apple, or just the apple, is a “meal”.
My basic understanding of “set weight” relies on not spiking your insulin as often, nor to such a degree as something with a lot of sugar/carbs would to train your body over time to a lower weight.
So, to avoid spiking your insulin, you either have to eat less often, less carbs, or less often AND less carbs.
So… in short, yeah the 200-300 calories during the day count as a meal, and you’re not in a fasted state after eating those things.
