Jess don't get disheartened.
If you are going to someones place or going shopping eat before you go! That way you aren't tempted to dig into the food. All logic goes out the window when your hungry. Also eat before doing grocery shopping, it helps you to walk past what you don't need.
The selection of meals i eat during the week consist of a lot of vegies, i love them. If you want something easy grill some chicken and boil or steam some carrot, brocolli and pumpkin.
Or for something else thats easy cut into cubes potato, pumpking, sweet potato, carrot, cauliflower and pumpking and cook it in a fry pan on the stove, cook up small diced chicken, throw it together and add a little sweet chilli sauce, its yummy.
Eat off a smaller plates. i find my eyes a way bigger then my stomach so i load up my plate and make sure i eat it till its all gone and never stopped at full. Smaller bowl will make you think your eating more and slow you down a bit. Try to keep bad foods away from the house so your not tempted.
Last tip i can give is frind a sport or exercise you love to do so it doesn't feel like your forcing yourself.
I hope you can keep going Jess. You can't let yourself fall off the wagon (or go to hell in a handbasket)
I know you can do great at it.
