There is something to say about carbs and satiety at the end of the day. Some people will eat some fruit (strawberries?) with a protein yoghurt for example. If you’re so hungry that you can’t sleep; that’s unsustainable and not necessary.
Try going slow carb (Tim Ferris) and make sure you are eating enough.
You need to eat your daily calorie intake in your eating window, as a man 1500 minimum, usually more. As suggested tighten your window to 4 or 6 hours. Make sure you feast during you window, two legit meals, or one giant one ( I find that hard with a shrunken stomach).
I use to do keto. Now I mostly do OMAD or 2 meals max. I’m still very carb conscious but I’ll eat pasta every now and then. I also don’t waste my carb count on things that don’t fill me up like juice, soda or candy.
Try whole grains like bulger or farrow. They keep me feeling full longer. I also strive for a gallon of water and that helps too. (I count green tea or flavored water in that amount but not my black coffe) Sometimes being thirsty can come off as being hungry.
I would go with more filling food. I do the same eating window and only 1100-1200 calories, but I’m a female with relatively low muscle mass. I eat chicken, rice, and veggies at 5:30pm and then half a cup of cottage cheese and half a banana right before the end of my eating window. Try solids instead of liquids. I do a protein shake for my snack between my lunch and dinner.
Know what helped me? Vitamin C tabs. Those big orange ones from Costco. Grabbed 2, sometimes 3 of those and crunch them, then a glass of water.
Your intake is low. Monitor your progress and adjust your intake if you’re dropping too fast. 1/3 chicken breast, spiced and sliced up thin (plain) is my late night cheat snack.
