Overall calories, you're hitting 151 grams of protein a day.
So your absolute minimum is 604 calories a day.
Obviously if you eat a lot of meat you're going to be getting a bit of fat in there too.
My favorite meal to have during dieting is a fryup of shredded chicken and onions with lots and lots of spices. Onions have like 3 grams of sugar in them so I plan around this by drinking protein shakes the rest of the time.
The 30 grams of carbs aren't a goal, they're an upper limit until you're no longer in ketosis. It's wiggle room for supplements, protein powders, and the occasional scoop of gatorade during a workout.
As a category 3 you get 2 cheat meals a week. These are regular, normal meals which a normal person might have three times a day. They are not a trip to the local buffet or an eight course meal at a restaurant.
It's up to you as to when you do your cheat meals. Before, after, or around a workout is the usual advice. These are just for diet compliance so don't wig out too much as to what you do, you're fat enough to live off your fat without seriously effecting your hormone profile.
I recommend giving it a solid go for at least six weeks and then see where you're at body fat percentage-wise, or if you even have the will to continue at that point.
Things I've learned since my original post.
1) Fiber supplements are an absolute necessity unless you want to wage total war in a public restroom. You know what I mean here.
2) Don't try to do too much in the gym, hit a few lifts hard with low volume and go home. You're not going to be gaining a serious amount of strength on a starvation diet.
3) Expect to sleep lighter on the diet. I'm usually a very heavy sleeper but during RFL dieting I wake up a lot more in the middle of the night from random sounds and whatnot.
4) If you're not lifting, you don't have to eat as much protein. Honestly I recommend eating that much protein anyways because you're going to want something in your stomach.
5) Avoid excess cardio.
6) Make a tea out of a chicken or beef bouillon cube in order to get electrolytes. Drink it if you're feeling lightheaded.
7) Unless you enjoy eating pounds of chicken every day I recommend buying a quality protein powder that is low in fat and more importantly carbs. I generally recommend Syntrax Matrix or MyProtein Impact Whey depending on your budget.
