Curb your blood sugar
You can also improve blood sugar levels after meals without using drugs. There are two important approaches.
Firstly, if a small, protein rich snack is taken first thing in the morning, and breakfast is delayed for two hours, the rise in blood glucose after breakfast is reduced by about one half. This is called the second meal effect and although it has been recognised in non-diabetic individuals for almost a century, it has only recently been shown to work in people with type 2 diabetes.
Secondly, if you go out for a half hour walk after a meal (or do any physical activity) then the rise in blood glucose will be very much less compared to just sitting in a chair. This is because muscle tissue takes up glucose more rapidly during exercise, and the meal time rise in glucose is blunted.

my personal note:
from the breakfast to be taken -
if you can remove the protein portion first,
it may not disturb the total calories.
in a way this is the "several small meals advice" modified.
