This is something I didn’t do the very first time I did a keto diet and wasted a lot of time not really understanding what I was eating.
Keto urine testing strips measure the level of ketones in your urine which indicates how much into ketosis and fat burning you are. The darker the colour the stronger the level.
I’d really recommend these because if you test and the strips go white indicating you have fallen out of ketosis you can then quickly assess what you have eaten incorrectly. It’s such a great guide to make sure you stay on track. Lots of fitness people use these to get stronger and stronger ketosis but for beginning and learning I think it’s a good measuring stick and guide.
