I came off MJ because of side-effects after 3 months but still have weight to lose. The hunger has been pretty intense, but it was before MJ as well, so just back to normal. People who blithely say they have one meal a day, or that if you ‘ignore the hunger it goes away’ have no idea. I sometimes wake at 3am absolutely ravenous and have to eat, I can’t get back to sleep otherwise. I am aiming for 1200 calories (I’m short) but have been ending up at 1700 calories which is my maintenance.
BUT, I seem to have found a solution. I got a CGM for a couple of weeks to try and see what really amped up my blood sugar. I was surprised to see that my blood sugar doesn’t really spike that high, but does spike quite easily, and I am often hypoglycaemic, particularly overnight. I have changed my breakfast completely so that it is pretty much pure protein and I’m eating a lot more in one go rather than eating a bit, getting hungry again quickly, snacking etc. This morning I had 3 eggs, feta, spinach, then a couple of spoonfuls of natural yoghurt, chia, flax, raspberries. That lasted me for 5 hours which is unheard of. My previous oats, flax, yoghurt or whole meal toast with peanut butter would only last for an hour or so. For a snack just before bedtime I have half a banana with peanut butter. This stops me waking up at night - my previous snack of nuts and cheese just wasn’t enough.
Sorry for the essay but it’s really pleased me to have found some kind of solution for myself. Your 600 calories a day though OP is way too low to function on, you need to up it.
