Welcome @Flopisfatteningbingforchristmas .. basically the plan is ...
3 meals a day
2 snacks a day
Delicate portions (whatever they means! Probably not overspilling and heaving plates of food - sadly)
No sugar at all really. So the odd half a banana is fine and on plan plus an array of fruit - you don't see much in the way of tropical fruits really though. No honey. No dried fruits.
No bread, pasta, white rice, baked beans - although the odd GOOD slide of spelt or wholemeal is fine as is a wholemeal wrap or roll
Louise is fond of using the best ingredients you can find and afford. However you can do this plan relatively cheaply as the food really is pretty much every day food
Lots of Birchers, porridges, smoothies, veggies, chicken, fish , beef, salads, cheese , tofu, fruit etc features. Meals easy to assemble ... quinoa with veg and halloumi, a roast chicken with veg, roasted veg with feta, salmon with green veg, all sorts really
I'm vegetarian so I basically just stick to the principles and seem to be getting on ok
