It's good to see that you are trying to manage your glucose levels b4 they get out of control.
An OGTT requires you to be sedentary 2 hours post test. Being active 1 hour post defeated your "homemade" test. See this link http://en.wikipedia.org/wiki/Glucose_tolerance_test
Q: "What can be the normal glucose level after 3-4 hours lunch or dinner time"
A: Glucose peaks 2-3 hours after meals where the normal value is <180 mg/dl and the optimum is <140 mg/dl. Four hours you should be at or close to normal levels.
Q: "If i make daily activity is it normal to have lower values?
If i make exercise , can this lower my glucose level."
A: Appears these are the same question on activity worded differently. Yes, daily exercise helps to lower your glucose.
Q: "I learned that during exercise insulin is generated and that can lower my gluce level rapidly."
A: See this link http://www.faqs.org/faqs/diabetes/faq/part1/section-15.html
Q: "Now i bougt a glucose meter, maybe it is better to make my own test at home while i am sitting."
A: Read and understand the instructions that came with the meter. Or, Google the make and model number for a user guide. Its important that you understand how to use the meter correctly or you will get false positive readings.
Many thanks for the information that helps a lot.
I had been looking for that kind of information but could not find until now.
