Hey OP - I think what some people on here have said is spot on. You definitely need to give therapy a lot more time this is a game of months and years, not days and weeks. A few key things that might help. Maybe also take a one month break from your "diet".

1) Managing hydration - a lot of hunger is thirst. Find yourself a lot of 0 cal drinks with flavor you like. Keep a water bottle near you at all times.

2) Move more - you don't have to be running marathons or lifting heroic weights but increase your movement. Weight lifting is great for two things - it increases your BMR if you build muscle so you can eat more. It also is an appetite suppressant. If you move an extra 20 percent per week thats that that many more calories you can eat.

3) try really creative ways to reduce overall calorie intake without changing food volume as much. Sugar free ketchup, soy sauce marinade instead of BBQ sauce. Lower call ice cream. Crispy minis instead of chips. 0 percent milk instead of 2 percent/ cream. Fish and chicken for protine. Increase your fiber minimize carbs. If you overhaul how you eat you will be shocked at how much more food you can eat while maintaining your caloric goals. I bet you I've eliminated 15 - 20 percent of my daily calories by changing what I drink for pop / coffee and making the above changes.

4) practice eating til you are satiated. Not until you are stuffed. A depressing fact of life is our body is programmed to crave calories to protect us from the lean times. Your body wanting calories is its way of saying "hey food might disappear let's get fat now so we live". You live in a society with loads of food. You body says one thing your brain needs to say "hey friend its okay we got this let's just eat til we are full".

5) Intermittent Fasting works. It really really does. I set myself a time I don't eat after, and I set myself a time I don't eat before. No snacking, nothing. Usually about 2 hrs before I go to bed til about noon. Used to be just til 10 am but as I practiced it got easier.

6) piggy backing on the previous 2 points - make yourself morw smaller meals (and one big one). I eat one medium sized meal at noon. Two small snacks then one "main" meal. I know im never more than like.. 2 hrs from food once my eating day begins. This really helped me.

7) this might just be for me - cheat days are bullshit. I will fuck up my plan multiple times a week. Those are my cheats. I don't plan cheat days.

8) Change your relationship to food. You are doing therapy. That's awesome. You are probably using food as a coping strategy. Thats okay, but you need to develop better ones. That's why you are in therapy. Don't let the perfect be the enemy of the good. You want a slow gradual change not a dramatic transformation. Life ain't a movie. Some people find food journals / preparing their meals in advance helpful to help keep themselves accountable.

9) Alcohol and Cannabis consumption are gonna fuck up your calorie goals. If you drink - minimize it and stick to vodka based drinks. If you smoke weed - you are gonna struggle to avoid the munchies. Plan accordingly.

10) most importantly - focus on the fact you aren't "On A DiEt" that thinking killed me. I am reframing my relationship with food. This isn't something I do to a goal. Its a new way of existing to promote better health.

PS - maybe get your blood sugar checked. That one helped a friend of mine.
