I had a go using her diet but tbh the stupid rules drove me mad and I'm not actually convinced about it anyway - although do agree with her views on phase 1 (ie intolerances/candida etc) and processed foods.
After reading many books including dukan, ZH, Adore Yourself slim, south beach, lean and clean, what works for me is low carb low fat (but not no carb, just minimal grains) and no processed food. I eat lots of fruit and veg, eggs, fat free dairy, lean protein, oily fish, nuts & quorn.
So breakfast - 2 egg omelette, fat free yoghurt with oatbran (inspired from dukan!)
Lunch - salad veggies plus usually oily fish (generally from tin eg sardines, mackeral, tuna, smoked salmon. Dressing yoghurt based.
Dinner - mountains of veggies plus protein (chicken, turkey, lean beef mince, white fish, tofu, quorn etc etc - sometimes as stir -fry, sometimes with with chopped tomatoes and loads of veggies.
Snacks - when hungry - apple, nuts (25g portion), yoghurt. Maybe couple of oatcakes or ryvita with cottage cheese.
