I have always wanted to do this but so far struggled with what to eat, whether to eat at all and when on FD. Now I have a plan:
Breakfast: Green tea
Lunch: Can of tuna with steamed broccoli = 130kcal
Dinner: veggie soup = 150kcal
Snack: 30g pack of almonds = 175kcal
Total 455 kcal
So I could even have a cup of white tea with the extra 45 kcal 
I am hoping that having the almonds to nibble on will get me through moments where I would normally open a pack of biscuits or choccies.
I am not really overweight, just flabby and chubby after 2 DCs and I just don't feel right. I am binging more and hiding food, so I want to get back on track before I go downhill. Plus my mum died of cancer, so I am trying to reduce that risk as well as having all the other health benefits.
Here are my stats:
SW: 68.8kg / 10st 11.7lb
GW: 62kg / 9st 10.7lb
167cm height
Posting this so I can keep track, care to join me?
