For me:
Breakfast - usually Yoghurt mixed with a bit (I lie, a lot) of Peanut butter with berries. Sometimes vanilla essence, sometimes Lemon zest and juice and a bit of sweet cinnamon on top.
Sometimes I make an omelette using an omelette maker I got as a 'review' item from a well known web-based retailer. Cook up some ingredients in it (Mushroom and onion) and then thrown in some egg.
I have some low carb bread and usually some low carb batches I've made from a recipe in the Caldesi book. Sometimes have one of those with scrambled egg.
Lunch in the office
I usually take some celery, some home made mustard dressing and veg (Peppers, celery, cucumber, tomatoes) plus some cold meat (Usually chicken). Occasionally go for a subway salad at the nearest subway, or a Pret Salad. Sometimes take some of the low carb bread (LivLife) and have a sandwich. Occasionally make chicken leftovers into a salad with Apple and celery.
For daytime snacks I tend to eat a lot of Almonds or Oat crackers (Just one or two.) with almond butter on. Occasionally some dark chocolate (One or two squares.)
For the nut butters I only buy pure ones with nothing added.
Drinks: tend to drink black coffee in the morning, and then switch to caffeine-free coffee or 'red bush' tea in the afternoon. Diet sodas like Pepsi/Root Beer and water.
Dinner:
Usually some form of meat or fish with vegetables, which could be cauliflower, leeks, onions (I eat a LOT of onion, as I love it.) and tomatoes, steamed. Sometimes make a side order of mushrooms cooked in white wine, garlic and soy sauce.
Eat a lot of sea bass, Salmon and prawns. Use 'Konjac' noodles to make prawn stir fries (Zero carb). We make large curries using chicken and onion and tomatoes and they last a few days and also for lunch. have them with cauliflower rice (Pilau flavoured). I've made a large chile-con-carne from the diabetes.org website which was nice.
I use a lot of recipes in this book:
Caldesi low carb cookbook
They are generally easy and quick to make and very, very tasty. I have a few other books of theirs, but find this one is the best due to the quick and easy recipes.
I sometimes make banana pancakes for breakfast (Banana, peanut butter, egg) and also make banana muffins. They don't use a lot of banana.
Eating out:
Subway salad, Nandos, but occasionally have some potato or a small portion of pasta or chips. I find in small amounts they don't seem to affect my blood sugar levels and when I do an 'experiment' like this I test. For example, today I had a small cappuccino from Caffe Nero and blood sugar showed no rise at all.
At other restaurants I usually go for a dish on the menu but ask them to replace chips with salad, or get side orders of veg.
I occasionally have some Snafflin' Pig pork crunch, but am trying to keep the sat. fat low.
