Ok the allowed foods on 810 are:

275g white fish eg- cod, haddock

Choose one of the above options with either 3 tablespoons of salad or vegetables.
Green salad leaves such as rocket, lambs lettuce, watercress, raddiccio, little gem or romaine lettuces
Celery, cucumber or red radishes, courgettes or marrow.
Spinach, kale, turnips or taro tops.
Chinese leafy greens, such as pak choi or chinese cabbage.
Broccoli, cauliflower, or any cabbage even pickled!
Asparagus, fennel or celariac
You still have 3 cd meals a day in addition to the meal mentioned above. Plus you must also have you minimum fluid intake of 2.25 litres as with ss.
The losses with 810 are still good. I have just done 5 weeks on 810 and my weekly losses were on average 3lb's
Hope this helps you!
