Hello and welcome!!!!. Im not too sure who you are responding to but...
I will answer anyway
I havent lost any considerable amount of weight, but Im on my way.....4 month "anniversary" on this very day.

The first few days (or first week) of LCing is pretty tough. You go through some sugar and carb withdrawal. I felt sick, headache, nautious and VERY tired. My headaches were so bad I thought I was going to pass out. MAJOR MAJOR sugar withdrawals.

You need to :
-drink lots of water
-take vitamins
-exercise
-EAT enough--you have to eat 10-12X your weight in calories! I am 268 so I eat about 2600-2800 calories a day!
-You may find that you have a bit of trouble sleeping the first few days-that will pass and then you will sleep like a baby!
-you may get a bit constipated. Make sure you drink a lot of water
-EAT at LEAST 20g carbs a day through veggies. You do not want to go to NO carb-you need the 20g minimum to properly function, especially during your first few weeks.

The LC way does work! I feel like a million bucks after 4 months. I felt great after the first week. You just have to commit and make up your mind! You will do great!

Hope this helps you a bit.
