You could say that. When you don’t feed your body glucose, after depleting your stored glycogen, your body starts producing ketones but it is not yet efficient as using them as an energy source so you end up peeing some out, hence the urine ketone strips registering ketones. As you continue to keep carbs low, your mitochondria go through changes or adaptations to using fat as fuel, whether its the fat you eat or stored body fat. This transition period usually takes 6-8 weeks. During this adaptation phase, make sure you are eating plenty of fat so you’re giving your body a source of energy since you are no longer giving it glucose and your not efficient as using fat as energy.
I would suggest too that you increase your calories. 1380 seems a bit low for someone of your height. You may first see an increase in weight but as you keep calm and keto on (KCKO), you will most likely see a drop in body fat.
