Hi, low carb / ketogenic diet.
I don't eat any grains, fruit, starchy vegetables, or anything with added sugars.
I eat salad and green vetables, nuts (in moderation), meats, eggs, cheese, butter, cream.
Look up Bernstein diabetes university on utube. lots of great information.
I can't believe you don't eat grains & fruit, grains are bread, & isn't some fruit better for you berry family?
this is what works for me and means I use very little insulin and rarely have highs or lows (and never rapid ones), and can keep an a1c in the low 5s.
theoretically on low carb I can eat some berries from time to time. Truth be told though, I am not a fruit eater. I much prefer vegetables (greens, celery, capsicum, tomato, egg plant, pumpkin, beans, avocado, etc). I do eat upripe fruits such as green papaya and green mango occassionally.
I don't miss grains at all. they give me indigestion. I do make low carb breads from time to time (particularly for my children) out of almond flour or coconut flour. There are some great low carb website for lowcarb baking (alldayIdreamaboutfood) is a great one. However, I mostly just stick with basic foods.
Breakfast is typically just coffee with cream. Both lunch and dinner will typically be some sort of meat and veges.
