Hi Volly and welcome…glad you’ve got a start date in mind. It is a bit daunting as its a complete change for lots of people so I understand how you feel in terms of wondering how to shop.
I do a sort of variation on the recipes using what I enjoy, keeping it simple and making sure I can prepare something easily when I get home from work or need to take lunch. It might be a bit unadventurous but I find that it works for me. I can tell you what My shopping list is – obviously I don’t buy all this every week but have a vague idea for meals and keep chicken/Turkey/salmon in the freezer:
Whole Milk – for coffee/ tea
Greek Yoghurt – full fat – good for breakfast with a very few seeds/almonds/ raisins/ground flax (they sell packs in Aldi/Lidl)
Coconut oil – for cooking
Olive oil – to make salad dressing with mustard and vinegar (only use a v small amount but keep in fridge)
Coconut milk (use for stir fries but only a tbls or so and keep the rest in jam jar in fridge)
Chilli flakes, fish/soy sauce, bottled lime juice – use for stir fries
Full fat cottage cheese – make the simple egg muffins in the recipe section so sometimes add a bit of feta, ham or bacon – good for breakfast/lunch
Eggs -boiled, scrambled, omelettes
Chicken/turkey breast – for stir fries or to have with veg
Salmon or other fish to serve with veg and/ or salad
Smoked mackerel/ tinned sardines/tinned tuna – good for lunch with salad and a few chickpeas
Mushrooms -button and flat – good for breakfast
Chickpeas- to make hummus, chuck in a salad etc
Brown rice – I buy packets of ready cooked and just use a couple of tablespoons and keep the rest
Green veg – broccoli, cabbage, pak choi, green beans, courgettes etc- whatever you like for stir fries, steaming etc
Salad veg – cucumber, tomatoes, radishes, peppers, red cabbage, spring onions, watercress, rocket , lettuce etc
Sirloin steak – about once a fortnight
Sorry this is such a long post but hope it helps – I’ve done three weeks and am 12lbs down- all the food looks expensive but it’s not really because not buying all the usual extras I find I actually use everything with no waste.
Good luck and hope it goes well for you!
