Hi starbear, the Scarsdale diet fits in well with family meals. Lots of meat, fruit and veg/salad. He tells you what to eat for 2 weeks no restrictions on portion size, but you have to eat what he says! then you have 2 weeks off, on the maintenance diet, when you can eat whatever you want except fat, sugar and starches.
I'm making it sound far harder than it is. This site has the diet all written out.
I love the Scarsdale diet. Today I've had:
fruit for breakfast; cold meat and tomatoes for lunch; prawn salad for dinner, with fruit for pudding. Tomorrow it's fruit for breakfast (it's always fruit for breakfast, with black coffee and a slice of dry toast!), fruit salad for lunch, hamburger (as much as you want!) and salad for dinner.
I cook the family the same as my meals, but add potatoes or pasta, etc, to bulk them out into "proper" meals.
It forces you to eat shedloads of fruit and veg. It's strict, but I lovelovelove it. You lose weight quickly and last time it all stayed off, till I got up the duff again.
