Hey
welcome to the forums and the best decision u have ever made!!! If you stay strong and get into the right frame of mind, this will change your life. You are only 16 bless you, you are doing this at the right time!!!
Firstly... Don't get the chicken soups lol. I felt exactly the same and they are hideous!! I only get the choc and strawberry shakes... If u blend then and stick a couple ice cubes in they are HEAVEN!! so don't be disheartened... The soup is feckin hideous!!!
Anyway... This is gonna be a tough week... You will feel very tired and you are likely to obsess about food, get voices telling you that you won't succeed, and that tell you to scoff some food... But please please just fight through and know it won't last! I'm in week 3 and it's a breeze now. Until u get properly into ketosis it will be very difficult. Just drink as much water as u can... At least 2 litres but more if you can. Keep busy, stay focused on your goal, and most importantly believe in yourself!!! Because you CAN do it... And these forums will help you through. The people in here are amazing and are here to support you, offer advice and share their journeys so that we are all in it together. It really helps!! Everytime the fridge starts calling you, just come here and read through diaries and chat to people. You won't believe how much it gets you through your tough moments.
Also it helps to set up a weight ticker and write a diary. It's great to see your progress!
It's gonna be a long journey but take every day as it is, don't think of it as a whole because it can be so daunting. Just know that for TODAY you are going to be strong and stick to your shakes. And every day it will get easier. You are the maker ofyour own destiny hun and you are 100% capable of being the slim, confident person that you want to be!! Watch the inspirational slideshow at the top to see all the other people who achieved it cuz it truly is inspirational. If they can do it, we can do it!!
Wish you all the best with your journey and if u need any help or support just ask and someone will be there for you xx
