If the objective of IM is to enter a state of ketosis, 10 hours is not enough time or at least for me. I used to be a LCHF diet rider and monitored my ketones with a meter. It takes days to enter ketosis. Fat just melts off in that state and once you are used to it. Anyone who does a thru hike on the AT, knows this because they are always in a fat burning mode and it takes a couple weeks to get there. I suppose my diet now is constantly IM since dinner is at 5:30 pm and then I break fast at 8:30 am. Perhaps, IM is just a technique to avoid snacking after dinner?
