I wouldn't say the process is reset, you don't go back to your normal Insulin Resistance GH/autography/etc. just because you consume a few calories. Many people advocate it even up to 500 cals a day. I wouldn't call that fasting at all though, that's just eating at an extreme caloric deficit. But back to the point, it does bog down the process while you switch back to a carbolic digestive system until that protein/carb/fat is broken down into insulin and used. This is what I understand of it, so far and I'm not a medical professional. Maybe [the way Dr.Ekberg explains may make it more clear](https://youtu.be/Wzmacu2TgFg?t=1760)? Just do what you can, use it as an exercise in self-discipline or whatever you are pursuing. It's your first time, EXPERIMENT, grow, learn. One more thing I didn't mention is you will be more thirsty. If you decide to start doing this every week you may want to look into taking more salt, potassium, D3, K2 and Magnesium. Don't worry about it this time, it's just 48 hours.
