[QUOTE=phunkscene;1565106411]Thanks a lot, for the reply. Problem is that im still recovering from a crash diet. Eating around 1800 calories. I’m scared that if i start lean bulking, then most of it will go into fat. Not to mention that ive been hit hard with an eating disorder :([/QUOTE]
As suggested you can try reverse dieting although I believe the science behind it doesn't really show any benefit for the general population other then preparing your mind and stomach to eat more food (your 'appetite thermostat' is usually lower when dieting). It is advised if you have been cutting for a long time, its a good thing to eat at maintenance calories (minus about 100-200 as your new cut maintenance is lower then your bulked one) for two weeks to stabilize all the hormones involved during a cut (remember you may add some weight during this phase or at the start of the lean bulk which is a tad larger then expected due to water weight and glycogen levels increasing this completely normal and expected).
Then add calories until you start gaining 1-2lbs a month, according to some scientific thinkers as long as you train hard with correct volume/ weight and eat a small surplus of calories (200-300 calories above your new maintenance) after this two week of maintenance, a optimum amount of weight gain will be muscle (please remember though you will add some fat never freak out as its a lot quicker to lose fat later then it is to build muscle).
As for the eating disorder I can't offer any advice as only a professional can do that, however one thing to remember is that you can't get fat over night it takes a prolong period of overeat to get fat so if you stay in the range of 1-2lb a month (excluding the first month due to water and glycogen) then you are doing it correctly.
