Enjoy it! Some more carbs for you - all by the 100gm portion: Asparagus is 2; so is celariac, courgette,fennel,lambs lettuce, radishes, spinach. Celery, cucumber,kale, ordinary lettuce, are only 1 gm per 100gm. Mushrooms are zero carbs - so is steak, roast sirloin, belly pork and pork chops (but not sausages),chicken, goose, duck, turkey - basically any meat you buy from the butcher and cook at home so you know there are no additives are zero carb.. Nuts are hugely fattening (alas) but have fairly low carbs: walnuts 1 carb per 30gms,almonds 3 carbs for 30 gms. You can eat eggs until they are coming out of your ears.
Avoid all breakfast cereal as a product from Hell (lots of sugar hidden away in it). Some people manage porridge (but sadly I can't) made with real oats not that instant muck - think about adding cream instead of milk as it is lower in carbs - indeed it is close to zero - but no sugar/syrup/honey (sorry about that).. A very small bowlful containing 9gms of oats has 9 carbs- a decent sized one (45gs of uncooked oats) 44 carbs.
Milk contains sugar (lactose) but Fage Greek Yoghurt is only 3 carbs per 100gms. There is no need to be hungry just because you are cutting down on carbs.
Fruit is a bit difficult - blueberries are 9 carbs to the 100gm but blackberries only 5 as are raspberries, strawberries are 6 carbs, apples are 10, kiwi fruit,9, peach 8 as is plum - most of the tropical stuff is out of sight - mango 14/pomegranite seeds 16 etc. The book says rhubarb is only 1 carb per 100gm but nobody with normal tastbuds can eat the horrible stuff without 100 gms of sugar to improve the taste....
Do not attempt to go too quickly in reducing carbs. To get down to my level you have to reduce slowly or face keto flu and constipation which would daunt a cement mixer. Until you experiment a bit you will not know how many carbs you can tolerate so let your meter be your guide. Take it steadily, do not panic, and do not let yourself get hungry or you will make silly diet choices like "Oh blow this for a game of soldiers - 2 pints of your best landlord and I'll have a pork pie and chips...." When deciding on veggies look at those with high fibre as well as lowish calories (i.e under 5carbs per 100gms) because fibre slows the absorbtion of the carbs which helps stop your BG spiking (it also avoids the cement mixer syndrome). Good luck and buy the book or download the app.
