What @KBG said. If you feel like eating everything in sight, go ahead. The only thing is make sure it is fat. The other day I made the eggnog recipe someone posted recently. It was a 16 oz of HWC, a cup of coconut milk, 2 tablespoons of swerve 4 eggs and some other things. I meant to only drink one glass but I ended up drinking the entire thing (honestly was not that great but I am told if you let it sit overight it is much better). Other than feeling a little too full I had no bad effects and ended up starting a fast the next day. Since I do not weigh myself during the fast I have no idea but I felt fine the next morning and did not feel bulgy or bloated and my clothes felt the same the next day.
Stop focusing on calories, this diet has nothing to do with calories or even macro percentages, stop tracking everything. The main limitation is carbs. With protein do not eat it to excess. Do not go for that 3rd or 4th piece of chicken like on a high protein diet. As for the first two pieces, stop weighing it and just eat a normal serving. With fat, limit fat bombs and nuts, especially macadamias but otherwise enjoy and eat until you are satisfied. Then stop.
At this point since you are ready to give up anyway, you have no downside to trying it this way but stop counting calories
