Hi Rachellee, I know how hard it is to get properly motivated to get started on a diet, but you really need to have a good talk to yourself.
First, how badly do you want to lose weight? What are your reasons for wanting to lose weight, is your need to lose it stronger than your need to eat something nice. You really do need to think about this and be very clear in your mind about how badly you want this.
If you decide that this is the time to go for it, you need to devise a plan that you can stick to. Just cutting down on snacks is too open ended, it leaves too much leeway to go wrong. One thing that you must concentrate on is that you must eat food you can enjoy. There is nothing more miserable, and more likely to make you fail than having to eat something you really dont go for. So if you really dont like salad for instance, then dont eat it. Whats the point.
Then you need to take a deep breath and go look in your cupboards and fridge, then throw out everything you know will sabotage your resolve, then make a shopping list and go shopping and buy only what you need for the next 2 or 3 days. Do not buy anything thats not on the shopping list, even if its something you spot in the supermarket that might be good to add into your diet. If you really want it, add it to a new shopping list and buy it next time.
Also, treat yourself to a good book, or something you can concentrate on to take your mind off food. If you can just have 3 days of being resolved and really good then you will find that the following days are so much easier to get through. I always believe the first 3 days are crucial
One of the key things to make a diet work is to make sure you have the right foods in the house and none of the wrong things.
Good luck! Keep blogging and let us knwo how you get on. We all want you to succeed!
