Hi - it's not so much that you're eating so little you're starving yourself - for me (have been taking it since January), yes my portions are smaller now - I use a side plate for meals instead of a big plate and I get full much quicker than before. I'm probably eating half in volume of what I used to eat - but I'm eating protein and veg, very little or no carbs most of the time. That's not even a deliberate choice - it's just what my body wants to eat!
So a meal for me might be a chicken thigh on spinach (am obsessed with baby leaf spinach at the moment), with some broccoli, cherry toms and dollops of greek yoghurt. Or a couple of sausages on the same, etc.
Breakfast for me tends to be a fruit smoothie, with lots of frozen fruit, dates, flaxseed, greek yog and milk.
I've not eaten any 'naughty' things since starting - my cravings for sweets, chocolate and crisps has completely disappeared and I've reduced my alcohol intake dramatically.
So for me it's been about listening to what my body wants to eat - which pre-MJ was impossible because of the 'food noise' telling me to eat all the time! I've now got space to think about what I want to eat, without eating and drinking all the time.
I don't count calories, but know that I must have reduced my intake significantly just by cutting out crap and reducing portion sizes - and I never feel massively hungry. Am definitely not starving though - I've got lots of protein-y stuff in the fridge which keeps me full!
