I have found I need to increase protein, and I have found that doing this in the morning over the “fast” period benefits me in many ways, energy and injury healing as well as mentally.

Will having a protein shake at 9:30am pull me out of fat burning mode?

“having a shame at 9:30am” is a fantastic Freudian slip 🙂

Thanks for taking the time to reply. I’m doing IF 5 days a week.

As far as i understand, brushing your teeth, having a small amount of milk in tea, water with lemon squeezed in etc, while these things result in calories entering the system, they don’t stop your fast.

I have read that as a general rule of thumb, if you drink something with less than 50 calories you are still fasting.

This is my question about the shake. If you look at the calorie counts, they are low, energy is round 100 calories, that they are more comparable with a cup of tea with milk than a meal.

So does taking in this amount of energy end your fast? Where is the cut-off if so? 50 cals? 75 cals? Then I can titrate my protein shake to fit in and see if it works.

Does this make sense?
