Keeping to 20g net carbs (carbs minus fibre) and tracking using my fitness pal. Total calories for the day are 1500 net, allowing for exercise. And I count everything, a wander to/from shops, walking with DS to the local park etc.
There are a few websites I've looked at for recipe ideas, there's one that has ruled.me in the address. There is another called Ditch The Carbs.
Our menu has been pretty boring, to be honest. I tend to have two proper meals a day and then some snacks.
Breakfast/lunch
Espresso coffee, sometimes with single cream instead of milk
Bacon, eggs, mushroom and spinach
Salmon scrambled eggs (made with 2-3 eggs and cream)
Ham roll ups with cream cheese and cucumber with a boiled egg or two, slice of cheese
Leftovers from dinner
Dinners
180-230g serve of meat, LC sausages or fish with fat left on, served with roasted or steamed veg like broccoli, cauli, sprouts, asparagus, spinach, zucchini, small amount of carrot
Meatballs in creamy sauce served with zucchini pasta
Chicken breast stuffed with ham, spinach and Brie with veg
Mexican-style mince with salad (google for Linda's low carb seasoning mix)
Adapted low carb bolognaise sauce with zucchini pasta
Another side is broc/cauli vegie bake with cheesy cream sauce
Adapted Thai or Indian curries with cauli rice (can buy cheaply pre-done from Asda)
Snacks
Sugar free jelly
Pork scratchings
Sugar free soft drink or squash
Ganache made with double cream and 80% chocolate
'Mousse' made with double cream and 100% cocoa powder. You can also make real mousse with eggs and chocolate but it takes longer and is more of a faff
Slices of ham and cheese
Earl Grey tea
The idea is after a week or so, you shouldn't really be looking for snacks in between meals as the fat helps to keep you feeling full
Measure everything and record accurately. Watch carb content in veg, even the ones I listed contain some carbs. Some version of LC say you can have as many green leafy vegies that you want, but I still prefer to track everything and keep to
