This is my first 600 cal day of the 5:2 plan. If it works well, I may just stick to the same thing every low-cal day, but I thought I'd share it and suggest others do the same. It might give us ideas:
Coarse Oatmeal Porridge 60g & water 222
Black Coffee 6
Banana 125g 120
Steamed White Fish 150g 150
Raw Cucumber 200g 20
Wholemeal Bread Slice 36g 80
Total 598
