I'm finding my levels peak at the 3 hour mark...

Certainly the more fat you eat with a meal will have a bearing, but this normally keeps the peaks lower and longer. Also whether any carbs are slow release ones, which also keeps the peaks longer. Also how bad your insulin resistance is. Also whether you have a slow digestive tract. There are so many factors involved.

Unfortunately, two tests, one at 2hrs and one at 3 won’t tell you when your peak is. They are just two dots on a wiggly graph line that you can’t see, so you’ve no idea what happens inbetween, or whether the number is rising or falling.

In reality you could be getting a double peak, one (before 2 hrs) from the carbs, then a second peak from protein, and the second peak could be rising or falling at 3 hrs...

Sorry to be the bearer of bad news.
When I got the Libre and actually saw, with my own eyes, the amount of ups, downs, wiggles and molehills my bg achieves in a given day, I was stunned. Exercise, stress, snacks, etc. etc.

I lost faith in prick testing for a while, but then the Libre showed me a whole new, more flexible way to view things. Trends, and the teeter totter play of sleep (deprivation), meal times, different cabs (grains v root veg), fat and fibre impact...

I would recommend people try a single Libre sensor when they are getting to grips with their testing regime. It is a brilliant learning curve, and the 2 weeks it runs for is enough to answer many questions.

@Brunneria Thank you for your informative reply. I'd love to try a libre sensor I've been looking into it.just wish it wasn't so expensive

They are very useful. If you can put one on your birthday list you will find it worth it. You only need one or two to see what happens.

Im definitely going to consider getting one . In the mean time Should I keep testing at 3 hours or should I save strips and just test at 2 hours?

Until you find some consistency with your peak times, I would suggest you test your main meals at 1, 2, 3, and 4 hours to determine if you are still on the rise at 2 hours and when you start to reach base line again. You don't need to do this for long, just until you find a pattern.
