As long as you have eaten your daily calories, stay strong and drink plenty of water!! Just get through today.
I think food can be much like any addiction. Our body sends signals to tell us we are not eating like we have been. It's like our body is using a bullhorn "HEY! WHAT'S GOING ON HERE?? YOU NEED TO EAT MORE SO WE DON'T LOSE ANYMORE WEIGHT!!" "SOS...SEND MORE FOOD!!"
Once your body gets accustomed to not eating certain foods or as many calories, it will behave and not bother you as much! Stay strong and show that hunger who's boss!!!
I know it's a silly analogy, but I use it to get through a tough craving time
