Keep at it Hun!!! Draw a line under today and start again tomorrow. I've said this to say many people who've struggled with low losses, and I've even been there myself with a couple frustrating weeks of staying the same!!!
What happens when you start a diet like CD is this:
In the first week a lot of what you Lise is water and glycogen weight. In some people glycogen stores can weigh up to 4lbs!!!
The second third and sometimes fourth weeks your body is adjusting to the new lower calories. It works to it's own times scale and has no idea you've put it on a diet. The body still functions in a very primitive fashion.
Because you've put it on a VLCD it automatically assumes that it's starving to death and hangs onto it's fat stores initially, then after a couple of weeks it realizes that it's getting these 500 ish calories on a regular basis and it won't starve to death, this is when your fat reserves get used up.
By eating things that have lots of carbs in your body will take the easy option always, and burn the carbs fir fuel first, before turning to the harder to break down stuff - fat!! Once the carbs are gone on then does it knuckle down and start on the fat.
I like to think that there's little miners inside, they pick the walls they have to tunnel through. Iif you have high carb high cal food wall they choose to tunnel through is going to be the clay carb glycogen wall, cos they're lazy little monsters. Then once that wall has gone they get bored and make a start on the harder fat wall. Occasionally they go on strike, hoping that they'll get another clay wall to tunnel through.
I prefer to punish my mini miners by making them work at the fat wall, this keeps me happy lol.
I hope this helps you understand what's happening to your body without sounding too much like a lecture and I hope you don't think that the miner analogy is too patronizing but it's how it was explained to me.
Stick with it it's worth it!!! xxx
