Last 4 months I did below,
1. Intermittent fasting 16/8
2. Normal meal at lunch but keto meal at dinner. By 3 pm my blood sugar is near 100.
So 21 hours my blood sugar is below 100.
3. Daily exercise and sports
Still my A1C is refused to go down. It did from 6.3 to 6.2.
Is this common? What I should be doing to take A1C below 5?
Hi and welcome. Thing about reducing carb: keto is a level of carb intake that induces dietary ketosis - which is when the body uses bodyfat for fuel. Ketones are a product of this and will be picked up by using keto stix to test pee.
The problem is that a "keto meal" (whatever that is) plus a "normal meal" might not when taken together be low enough carb to induce ketosis or to lower the amount of glucose entering your system. In practical terms: some meat and cheese and a hard boiled egg for dinner is practically zero carb. However, if you have pie, chips, and gravy for lunch that is going to be a meal high enough in carbs to ensure you're not going to be anywhere near ketosis for a couple of days at least.
My experience over the last five years has been that anything over around 40g carb per day (not per meal) is enough to stop ketosis. That's approximately 2 slices of bread. You need to think of your food intake in terms of the whole day - one low carb meal might achieve nothing if your carb intake is high elsewhere.
