My food shopping has changed totally - but in a great way! We have a weekly Ocado order delivered on Friday (no naughty purchases then while in the supermarket hungry!), so am ready for the weekend. Everything we buy gets eaten now, the veggies are now longer going to waste. Cupboards are turning over and everything getting used. I've found lots of LCHF foods (Peters Yard crackers if you love your cheese, only 2 carbs each!) and discovering new recipes.
In 6 weeks since diagnosis I've lost over half a stone, down to sub 12 stone for first time in years. So all this healthy eating is good for you!
Need to head further afield to Lidl for those protein rolls, Camden branch doesn't do them sadly ...
Generally my food shopping has only improved - no more "I don't want the healthy stuff, I want a pie" evenings.
