OK - first of all, BREATHE.
You have lost 14lbs in 4 weeks! That is amazing. You have to remember that you are NOT going to see huge numbers on the scale every week - once your body adjusts to the diet you should average between 2-3lbs per week, which is exactly where you are at. You are not only following the plan, you are losing at the correct rate.
If you've read through the threads, you may have seen that spotting/wacky TOM is TOTALLY normal on IP. Women store estrogen in their fat cells, so when we drop a lot of weight quickly that estrogen floods our systems and can wreak havoc on our cycles AND our moods. Yes, it causes us to feel PMS symptoms a LOT in the beginning too. The good news - what you're feeling and experiencing is TOTALLY expected, and once your body has normalized a little on the diet and your weight loss is in a more consistent rhythm, you wont' see those things happening as much.
You probably won't see much of an effect on the scale from eating an extra restricted a few days in a row, but I wouldn't recommend making a habit of it. There are MANY things you can do to combat hunger:
-Drink extra water or hot tea. Thirst can mask as hunger, you may just be thirsty! If you drink something and 20 minutes later you aren't hungry, you were probably really thirsty
-Use the unlimited lettuce to your advantage. You can have as much romaine, iceberg or butter lettuce as you can stomach - and can be a good indicator of whether you're dealing with REAL hunger or MENTAL hunger. If the idea of eating a bowl of lettuce isn't appealing, you may not be PHYSICALLY hungry - try distracting yourself with something you like doing, or a task that you need to get done.
-You can have 2 egg whites per day as a "freebie" (in that amount they meet the 0/0/0 rule) - sometimes a little egg white omelet is just what you need to get you over a hunger hump.
-We really shouldn't be using an extra packet beyond the first week, but if you need it choose an unrestricted. Your body may be sensitive to carbs and easy to get out of ketosis - ketosis acts as an appetite suppressant. Restricted items are higher in carbs AND calories.
You CAN do this. No, it isn't going to be easy, but nothing worthwhile is really easy
Don't ever hesitate to post when you get frustrated - preferably BEFORE you grab for food - we have ALL been there and someone's experience may be just the thing that helps you push through! Good luck!
