I have replaced my previous breakfast of cereal with milk for yogurt and berries. I have swapped over to granary bread and reduced the amount to one slice max per meal, plus I still eat spuds every day but vastly lower amounts. I ditched low fat stuff for the real thing (butter, mayo and yogurt) Basically I eat the same meals I always did but with tiny portions of spuds and bread and increased amounts of mushrooms, tomatoes, cauliflower.
I have never eaten ready meals, never had a sweet tooth, rarely eat puddings, only binged on chocolate at Christmas, I don't like savoury rice or pasta so no problem there. (except homemade rice puddings, which I miss) I've never been big on veg except the ones we should avoid plus cauliflower, so again I still have peas and carrots but much smaller portions.
I have tried to make my diet fit round me and my 66 years of eating traditional food without changing too much rather than inventing a completely new diet.. This way I know I can sustain it with portion control, eat the same as my hubby and family, and not feel deprived. It is working. I have lost 17% of my body weight so far and my BS levels are coming down nicely without medication.
