Hello, I am a prefiabetic and practicing lchf diet since last 2 years ( few failures)
I am afraid I cannot stick to 20g carbs per day consistently so exploring other approaches as well ,
When you say eat to your meter what does it mean , postprandial glucose levels should be how much ideally I know less than 7.2 is normal but what is ideal ?
A) it should come back to pre meal blood glucose level or close to it
B) should not raised more than 2 mmol
My levels are always good hba1c is 4.7
LCHF is generally accepted to be under 130 g carbs a day, and 20g a day is actually pretty strict ketogenic, so there's no reason why you should have to stay that low carb unless you absolutely
need (or choose) to do so. You really only need to eat as few/many carbs per meal as you need to keep your glucose levels under control and this definitely doesn't
have to be a fixed number of carbs every day.
Eating to your meter is essentially a guide to help manage those carbs by monitoring your resulting glucose levels, so both your options A and B are useful, and are generally accepted recommendations rather than absolute requirements.
When you test will to a certain extent depend on what you're eating - e.g. for a carby meal try testing pre meal for your base level, then 1 hour post meal for any rise then the 2 hour point to see how close back to base you are; for combinations of higher carb and higher fat food (e.g. pizza) test pre meal, then 1 hour, 2 hours and 3 or so for a late spike; though this combination of both higher carbs and fats will give
me a long "hump" rather than a later sharp rise.
I follow both options depending what I want to know, and aim to have a minimum post meal rise followed by under 2mmol higher than pre meal at the 2 hour point if I'm monitoring something slightly higher carb than normal; otherwise, I aim to be back approximately where I started. The high (i.e. normal full) fat part of Low Carb High Fat for me is an important part of keeping my levels steady and stable.
