Hi, I'd echo all that Rosebud said. And don't worry about not showing ketones. Some folk never do and lose fine. You could be burning up all the ones you're producing and so leave none to excrete.
You sound like you're doing very well - keep up the good work! Those reports of people losing tens of pounds in induction are often from people who have 100+ to lose - as Rosebud says, you lose a proportion of what you have to lose - so for you, that will be a small number in actual pounds.
Take care, Jay
