The first two weeks were hard. I was hungry ALL. THE. TIME. I didn't feel too well the second week, due to the drastic change. It also messed with other certain bodily things that I won't go into detail about.
Then last week, week three, I was traveling. That was really hard, too. I didn't stay under my goal every day, but I just squeaked under the goal with my weekly average thanks to my propensity for barely eating when flying. Eating low calorie is incredibly difficult when you're forced to eat out for every meal.
I have a difficult time on the weekends due to the fact that I don't go to the gym. I try to substitute the Wii Fit some days, but I'm not always good about doing that and I don't get anywhere close to the same benefits as the gym equipment.
This week I've still been hungry every day during the day, though I'm finding it somewhat easier to deal with. I try to drink a lot of water (still working on that) and I chew gum to help with hunger cravings. My jaw is not happy with that solution, but it does help keep me from feeling as hungry. (I recommend Extra Root Beer Float!) The great thing, though, is that thanks to my workouts, I have plenty of extra calories at the end of the night and I can have a snack. That does wonders for a girl's mental health!
I weighed in again this morning and even after the travel week I've lost a total of 6 - 8 pounds in 4 weeks! (I changed scales, not sure how accurate the first one was.) My goal for healthy weight loss was 2 pounds per week, so I'm right on track. I hope this keeps up, but it is NOT easy.
