Ketosis Strips and Water

Answered on August 19, 2014
Created July 23, 2011 at 1:52 AM

I drink a lot of water, and as such my urine is usually clear or light light yellow. Does this high water content of my urine mean that the ketosis strips wont work or arent going to work as well?

I am losing weight relatively rapidly, but my ketosis strips are still not changing color. I dont much care because I am losing weight, but I would like to know what is going on biochemically in my body as much as I can...

It's true that your urine will be more concentrated, but the ketone levels will be lowest in the morning. It's best to check them last thing at night.

Yes if you drink a ton of water the amount of ketones in your urine will be less than otherwise. So it is less likely to show up on the sticks.

The best time to check your urine is first thing in the morning when you wake up. It will be most concentrated then and it's easier to get a positive. If you are drinking a lot of water throughout the day you are diluting your urine, and thus the ketones in it, and they are less likely to be detected by the sticks.

try measuring first thing in the AM since your urine will be less diluted.

At first I was testing at different times day to see what/how these work and to understand ketosis etc. I found that after eating, drinking lots water, the strips always come out negative.

If I wait and test before a meal, when I've perhaps not drank as much water or eaten for 4-6 hours, they tested stronger.

If you are indeed in ketosis then likely are ok and will be in out of it due to these reasons. You'll save a bundle on strips if you just test when you believe a positive result will occur....if it comes out negative when you know it should be positive, just pull back on your carbs a bit...that always worked for me.

I could almost never get the ketostix to change, even when I knew I was in ketosis because I was losing weight and wasn't hungry. I think something like 1 out of 10 people don't have measurable ketones in their urine even when in ketosis. It could be because of the water you're drinking, or it could be exercise-- exercise burns ketones. Kind of bothered me because I wanted to see the color change. The only time I could get it to change was mid-afternoon if I hadn't drank anything for several hours.

I know that dehydration causes false positives, meaning your specific gravity has concentrated and your ketones (and other ingredients) is of a greater percentage. By that logic, the opposite might be true. Is it possible you're over-hydrating? Also, ketostix gives a false negative if you have a certain amount of acetone...

Ketones are lowest in the morning and highest in the evening (especially if you have eaten fatty foods and done some exercise).

They are measured in mmol of ketone per litre of urine, so you can easily dilute them out by drinking too much liquid.

My experience (I check blood and urine ketones every day) is that when you are in deep ketosis you'll be able to change the colour at almost any time, but they'll be darkest at night (although as someome else noted above, the concentration will vary from person to person).

If you want a darker colour, cut down your protein intake to 0.6 to 1g per lb of lean body weight.

But as you say, it doesn't really matter than much...
