So yesterday you had: scrambled eggs with cheese, coffee and cream, chicken breasts and salad, yogurt and more cream?
If you're new to low carb then feeling very hungry is expected. Your body is craving the easy quick energy boost of carbs and not getting it. If you're hungry then eat. Chicken thighs or drumsticks would be better for satiation than chicken breasts unless you've fried them in butter and added a lot of oil to your salad dressing.
Your breakfast of eggs, bacon, cheese and mushrooms is a really good one as it it has lots of protein to satiate you and is a big, filling, calorific meal that should carry you through to your next meal without snacking. However, in this case it might have been too calorific as it led you to skip lunch and then end up extra hungry in the evening.
Coffee and cream as a meal is a bad idea as it could cause an insulin spike and a blood glucose dip that could well be what made you feel hungry. If you absolutely have coffee and cream then have it as a "dessert" straight after a meal rather than at a separate time.
It could be a mistake to have so many dairy-containing meals in one day. Some people tolerate dairy better than others but, as a rule of thumb, I would limit dairy consumption to no more than once or twice a day.
