And am sorry but food comas thing is pathetic, it means you have an eating disorder, you cut out too much of your body needs it plays you psychologically to get what it needs and more. Eat a diet rich in everything, but in moderation, i have 4 packs year round, am about 80kg with low bodyfat, and i eat chocolate almost everyday, or chips, as long as its in my macros, i alternate between a pasta, a bowl of rice, a candy that i want, don't take away something you want from yourself, if u keep this up, soon enough this wouldnt happen, i could have the tastiest foods infront of me and i wouldnt want to eat at all and am ex mega fatty too.
To start over give yourself 2-3 days of total freedom, eat anything you desire, fill yourself up with food till you hate it.. the following days your blood sugar might be a bit crazy but your desires for food will be under control, alot of water, fruits, veggies and proteins and you wont be that upset. go strong this way for 2-3 weeks and gradually introduce more carbohydrates as you go, more starchy and complex carbs early in the day, simple ones after workouts and late at night..
If you feel like it, my personal approach for year round goals is IF, i.e you fast 16 hours and eat your calories within 8 hours where you usually have your workout sometime in those 8 hours.. in the 16 hours you should sleep/do some walking and light cardio and consume zero calories and in the 8 hours, rest, workout and eat..
this is not the information you requested but i used to be somehow in your spot so am just helping a bro out, hope you dont take it the wrong way
