If you are efficiently burning ketones for fuel, they won't be showing up in your urine. At least not in any great amount, especially if you are physically active.
If your net carb intake is under 20 (maybe even under 50-100 depending on your metabloism) you
will be in ketosis. The more used to ketosis your body gets, the more efficient it becomes at burnig ketones ---> less ketones show up on your keto strip.
If you are judging success vs. failure by the color on a urine soaked stick rather than your body composition, you are doing it wrong.
And finally, the number one rule: if you are trying to lose weight on a ketogenic diet, macro ratios are meaningless for weightloss if you are not in a caloric deficit.
tl;dr during the initial 48 hours to a week of not eating carbs, keto sticks can be useful to see when you enter ketosis or to judge your carb intake threshold. Once your body starts to adapt to readily burning ketones, the strips will no longer show any major ketones.
