Per a previous glipizide response: onset of action is 90 minuets and the maximum effect happens between 2-4 hours later.
Why am I instructed to take glipizide 30 minutes before breakfast and dinner? My breakfast is usually small low carb and larger lunch, wouldn't glipizide be more effective after breakfast so maximum effectiveness aligns with higher carb meal?
Why take glipizide 30 minutes before breakfast and dinner?

Food intake interferes with the absorbtion of glipizide. If you take the medicine before a meal, the body can absorb it and its effects begun before the food reaches the stomach. If you take it after the meal, your glipizide levels will be much lower. Digestion takes several hours after a meal so if you took it after breakfast it wouldn't line up with lunch
You do raise an interesting question about whether you should take it before the larger meal.
