I've been tempted a few times but concerned about how processed it was and about piling it back on after my body getting used to eating no food.
I do a kind of own version but with real food. No breakfast, broth like soup for lunch. Snacks of black coffee with cream, babybel or egg then a 'normal' sized dinner of protein and veg.
Last night I had paneer, couliflour and courgette spinach. With a small amount of butter chicken and yoghurt.
Other nights
Bolognese meat with butter fried broccoli
Salmon in lemon, garlic and cream sauce with shredded spouts.
Burger patties with cheese, salsa and coleslaw
Chicken and bacon baked in creamy mushroom sauce.
Stir fried beef and broccoli with garlic and soy sauce.
Home made nuggets (chicken dipped in egg then parmesan) with hm ranch dressing and coleslaw.
Fajita chicken without the flatbread with fried peppers and onions, sour cream, cheese and salsa.
