On average it takes most people about three days to get into ketosis.The sticks will confirm that ketones are being excreted through your urine. That’s all. They won’t change color at all for no ketones, then there is trace (light pink) and it goes up from there to dark purple. The darkness of the stick doesn’t matter. As long as you are showing even trace amounts, then you are in ketosis and good to go. In fact, if you are showing really dark on the stick, you may be dehydrated and need to drink more water (see #4.)
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
